Loss of the tooth substance by chemical or mechanical processes
The wearing away of a tooth as a result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It is chiefly associated with aging. It is differentiated from TOOTH ABRASION (the pathologic wearing away of the tooth substance by friction, as brushing, bruxism, clenching, and other mechanical causes) and from TOOTH EROSION (the loss of substance caused by chemical action without bacterial action). (Jablonski, Dictionary of Dentistry, 1992, p86)

One of a set of bone-like structures in the mouth used for biting and chewing.
A disorder characterized by grinding and clenching of the teeth.
The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action. (From Jablonski, Dictionary of Dentistry, 1992, p2)

Diagnosis and treatment of dentinal hypersensitivity. (1/52)

This bibliographic review provides a general view of the etiology, characteristics and treatment of dentinal hypersensitivity, so that professionals can use this information in the therapeutic management of this clinical condition. For this purpose, the authors have analyzed whole texts of relevant articles on the subject. This study showed that the predisposing factors associated with the causes of dentinal hypersensitivity must be controlled or eliminated, by educating the patient regarding the excessive intake of acidic food, as well as providing guidance on the proper tooth brushing technique and analysis of occlusion. Effective treatment must be preceded by a proper diagnosis, established after the exclusion of any other possible causes of the pain. These cases must be managed efficiently, quickly and permanently. The availability of a wide variety of treatment could be an indicator that there is still no effective desensitizing agent to completely resolve the patient's discomfort, or that it is difficult to treat, irrespective of the available treatment options. Even with the large number of published studies, it has not been possible to reach a consensus about the product that represents the gold standard in the treatment of dentinal hypersensitivity.  (+info)

Reasons for placement of restorations on previously unrestored tooth surfaces by dentists in The Dental Practice-Based Research Network. (4/52)

OBJECTIVE: The authors conducted a study to identify and quantify the reasons used by dentists in The Dental Practice-Based Research Network (DPBRN) for placing restorations on unrestored permanent tooth surfaces and the dental materials they used in doing so. METHODS: A total of 229 DPBRN practitioner-investigators provided data from their practices regarding 9,890 consecutive restorations in 5,810 patients. Information the practitioner-investigators provided included their reasons for restoring the teeth, the specific teeth and surfaces they restored and the restorative materials they used. RESULTS: Primary caries (85 percent of teeth, 8,351 of 9,890) and noncarious defects (15 percent, 1,479 of 9,890) were the main reasons participants gave for placing restorations. Participants placed restorations necessitated by caries most frequently on occlusal surfaces (49 percent, 4,091 of 8,351). They used amalgam for 47 percent of the molar restorations and 45 percent of the premolar restorations. They used directly placed resin-based composite (RBC) for 48 percent of the molar restorations, 50 percent of the premolar restorations and 93 percent of the anterior restorations. CONCLUSION: DPBRN practitioner-investigators cited dental caries on occlusal and proximal surfaces of molar teeth as the main reasons for placing restorations on previously unrestored tooth surfaces. RBC was the material they used most commonly for occlusal and anterior restorations. Amalgam remains the material of choice to restore posterior teeth with proximal caries, although the authors noted significant differences in the use of amalgam and RBC by dentists in various regions of the DPBRN.  (+info)

Tooth wear: prevalence and associated factors in general practice patients. (5/52)


Tooth use and wear in three iron-biomineralizing mollusc species. (6/52)

Chitons and limpets harden their teeth with biominerals in order to scrape algae from hard rock surfaces. To elucidate relationships between tooth structure and function, light and electron microscopy were used to examine naturally worn teeth in three species of mollusc with iron-mineralized teeth and to analyze the grazing marks left by members of these species feeding on wax. For the two chiton species, teeth wore down progressively from the medial to the lateral edge of the cusp, while for the limpet, wear was more evenly distributed across the edges of each cusp. In chitons, this pattern of wear matched the medially biased morphology of the cusps in their protracted position and relates to what is known about the mineral composition and substructure of the teeth. The patterns of progressive tooth wear for each of these species, together with the distinct grazing marks left by each species on the wax substrate, indicate that the teeth are designed to remain functionally effective for as long as possible, and have proved to be a valuable means of rationalizing the internal architecture of the teeth at a range of spatial scales. This information is critical for ongoing studies aimed at understanding the interactions between the organic matrix and mineral components of these teeth.  (+info)

Tooth wear is the progressive loss of tooth structure that can occur as a result of various factors. According to the medical definition, it refers to the wearing down, rubbing away, or grinding off of the hard tissues of the teeth (enamel and dentin) due to mechanical forces or chemical processes.

There are three primary types of tooth wear:

1. Abrasion: This is the loss of tooth structure caused by friction from external sources, such as incorrect brushing techniques, bite appliances, or habits like nail-biting and pipe smoking.
2. Attrition: This type of tooth wear results from the natural wearing down of teeth due to occlusal forces during biting, chewing, and grinding. However, excessive attrition can occur due to bruxism (teeth grinding) or clenching.
3. Erosion: Chemical processes, such as acid attacks from dietary sources (e.g., citrus fruits, sodas, and sports drinks) or gastric reflux, cause the loss of tooth structure in this type of tooth wear. The enamel dissolves when exposed to low pH levels, leaving the dentin underneath vulnerable to further damage.

Professional dental examination and treatment may be necessary to address significant tooth wear and prevent further progression, which can lead to sensitivity, pain, and functional or aesthetic issues.

Tooth attrition is a type of wear on the teeth that results from normal dental occlusal forces during biting, chewing, and grinding of food. It involves the loss of tooth structure by mechanical forces and is typically seen as a flattening or reduction in the vertical height of the crowns of teeth.

Attrition differs from other types of tooth wear such as abrasion (which is caused by external factors like toothbrush bristles, toothpaste, or habitual pen/pencil biting), erosion (which is caused by chemical dissolution of tooth structure due to acid exposure), and abfraction (which is caused by flexural forces leading to cervical lesions).

While some degree of attrition is considered a normal part of the aging process, excessive attrition can lead to dental sensitivity, aesthetic concerns, and even affect the functionality of the teeth and overall oral health. Dental professionals may recommend various treatments such as fillings, crowns, or even orthodontic interventions to manage the consequences of severe tooth attrition.

Tooth erosion is defined as the progressive, irreversible loss of dental hard tissue, primarily caused by chemical dissolution from acids, rather than mechanical forces such as abrasion or attrition. These acids can originate from extrinsic sources like acidic foods and beverages, or intrinsic sources like gastric reflux or vomiting. The erosion process leads to a reduction in tooth structure, altering the shape and function of teeth, and potentially causing sensitivity, pain, and aesthetical concerns. Early detection and management of tooth erosion are crucial to prevent further progression and preserve dental health.

A tooth is a hard, calcified structure found in the jaws (upper and lower) of many vertebrates and used for biting and chewing food. In humans, a typical tooth has a crown, one or more roots, and three layers: the enamel (the outermost layer, hardest substance in the body), the dentin (the layer beneath the enamel), and the pulp (the innermost layer, containing nerves and blood vessels). Teeth are essential for proper nutrition, speech, and aesthetics. There are different types of teeth, including incisors, canines, premolars, and molars, each designed for specific functions in the mouth.

Bruxism is the medical term for grinding or clenching your teeth. It's often an unconscious habit that can occur during the day or at night (nocturnal bruxism). Mild bruxism may not require treatment, but chronic, severe grinding can lead to jaw disorders, headaches, and damaged teeth.

There are several potential causes of bruxism, including stress, anxiety, certain medications, alcohol and drug use, and sleep disorders. Dentists often diagnose bruxism based on the visible signs of wear on your teeth, or they may ask you about symptoms you're experiencing. Treatment for bruxism can include stress management techniques, dental guards to protect your teeth during sleep, and in some cases, medication.

Tooth abrasion is defined as the wearing away of tooth structure due to mechanical forces from activities such as tooth brushing, chewing, or habits like nail biting or pen chewing. It typically occurs at the gum line and can result in sensitive teeth, notches in the teeth near the gums, and even tooth loss if left untreated. The use of hard-bristled toothbrushes, excessive force while brushing, and abrasive toothpastes can all contribute to tooth abrasion.

A tooth crown is a type of dental restoration that covers the entire visible portion of a tooth, restoring its shape, size, and strength. It is typically made of materials like porcelain, ceramic, or metal alloys and is custom-made to fit over the prepared tooth. The tooth crown is cemented in place and becomes the new outer surface of the tooth, protecting it from further damage or decay.

The process of getting a tooth crown usually involves two dental appointments. During the first appointment, the dentist prepares the tooth by removing any decay or damaged tissue and shaping the tooth to accommodate the crown. An impression is then taken of the prepared tooth and sent to a dental laboratory where the crown is fabricated. In the meantime, a temporary crown is placed over the prepared tooth to protect it until the permanent crown is ready. At the second appointment, the temporary crown is removed, and the permanent crown is cemented in place.

Tooth crowns are often recommended for several reasons, including:

* To restore a broken or fractured tooth
* To protect a weakened tooth from further damage or decay
* To support a large filling when there isn't enough natural tooth structure left
* To cover a dental implant
* To improve the appearance of a discolored or misshapen tooth

Overall, a tooth crown is an effective and long-lasting solution for restoring damaged or decayed teeth and improving oral health.

"Papio cynocephalus" is a scientific name for a species of old world monkey, commonly known as the yellow baboon. It's not typically used in a medical context, but I can provide some general biological information about it if that would be helpful.

Yellow baboons are native to the savannas and woodlands of eastern and southern Africa. They have a distinct appearance with a dog-like face (hence the species name "cynocephalus," which means "dog-headed" in Greek) and a long, close-set coat that is yellowish-brown or olive green in color. Adult males can weigh between 33 to 82 pounds (15 to 37 kg), while females are smaller and typically weigh between 14 to 33 pounds (6 to 15 kg).

Yellow baboons live in large social groups called troops, which can consist of up to 200 individuals. They have a complex hierarchical social structure based on age, sex, and dominance. Their diet is omnivorous, consisting of fruits, seeds, nuts, insects, and small vertebrates.

In terms of medical relevance, yellow baboons are sometimes used as animal models in biomedical research due to their close genetic relationship with humans (they share about 96% of their DNA sequence with us). However, it's important to note that using non-human primates in research is a controversial topic and subject to ethical considerations.

Dental enamel is the hard, white, outermost layer of a tooth. It is a highly mineralized and avascular tissue, meaning it contains no living cells or blood vessels. Enamel is primarily composed of calcium and phosphate minerals and serves as the protective covering for the crown of a tooth, which is the portion visible above the gum line.

Enamel is the hardest substance in the human body, and its primary function is to provide structural support and protection to the underlying dentin and pulp tissues of the tooth. It also plays a crucial role in chewing and biting by helping to distribute forces evenly across the tooth surface during these activities.

Despite its hardness, dental enamel can still be susceptible to damage from factors such as tooth decay, erosion, and abrasion. Once damaged or lost, enamel cannot regenerate or repair itself, making it essential to maintain good oral hygiene practices and seek regular dental checkups to prevent enamel damage and protect overall oral health.

Dental photography is a type of clinical photography that focuses on documenting the condition and treatment of teeth and oral structures. It involves using specialized cameras, lenses, and lighting to capture high-quality images of the mouth and related areas. These images can be used for diagnostic purposes, patient education, treatment planning, communication with other dental professionals, and monitoring progress over time. Dental photography may include various types of shots, such as extraoral (outside the mouth) and intraoral (inside the mouth) views, close-ups of individual teeth or restorations, and full-face portraits. It requires a strong understanding of dental anatomy, lighting techniques, and image composition to produce accurate and informative images.

Toothbrushing is the act of cleaning teeth and gums using a toothbrush to remove plaque, food debris, and dental calculus (tartar) from the surfaces of the teeth and gums. It is typically performed using a soft-bristled toothbrush and fluoride toothpaste, with gentle circular or back-and-forth motions along the gumline and on all surfaces of the teeth. Toothbrushing should be done at least twice a day, preferably after every meal and before bedtime, for two minutes each time, to maintain good oral hygiene and prevent dental diseases such as tooth decay and gum disease. It is also recommended to brush the tongue to remove bacteria and freshen breath.

Dental occlusion refers to the alignment and contact between the upper and lower teeth when the jaws are closed. It is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or biting.

A proper dental occlusion, also known as a balanced occlusion, ensures that the teeth and jaw joints function harmoniously, reducing the risk of tooth wear, damage, and temporomandibular disorders (TMD). Malocclusion, on the other hand, refers to improper alignment or contact between the upper and lower teeth, which may require orthodontic treatment or dental restorations to correct.

Odontometry is a term used in dentistry that refers to the measurement of teeth, particularly the size and length of teeth or tooth roots. It is often used in forensic dentistry for identification purposes, such as in age estimation, sex determination, or individual identification of human remains. The measurements can be taken using various methods, including radiographs (x-rays), calipers, or specialized software.

In some contexts, odontometry may also refer to the process of measuring the amount of dental work required for a particular treatment plan, although this usage is less common.

Physical anthropology is a subfield of anthropology that focuses on the study of human biological variation and evolution, both in the past and in the present. It draws upon various scientific disciplines such as genetics, anatomy, physiology, and paleontology to understand the biological origins and development of our species, Homo sapiens.

Physical anthropologists study a wide range of topics, including human and primate evolution, population genetics, skeletal biology, forensic anthropology, and bioarchaeology. They often work with fossil remains, archaeological sites, and living populations to investigate questions related to human adaptation, health, migration, and diversity.

By examining the biological aspects of human existence, physical anthropologists aim to contribute to a more comprehensive understanding of what it means to be human, both in terms of our shared characteristics as a species and the unique variations that make each individual and population distinct.

I'm sorry for any confusion, but "Northwestern United States" is not a term that has a medical definition. It generally refers to a geographical region in the US, consisting of states like Washington, Oregon, Idaho, and sometimes Montana and Wyoming. If you have any questions related to medical topics, I'd be happy to try to help answer those!

Dentin is the hard, calcified tissue that lies beneath the enamel and cementum of a tooth. It forms the majority of the tooth's structure and is composed primarily of mineral salts (hydroxyapatite), collagenous proteins, and water. Dentin has a tubular structure, with microscopic channels called dentinal tubules that radiate outward from the pulp chamber (the center of the tooth containing nerves and blood vessels) to the exterior of the tooth. These tubules contain fluid and nerve endings that are responsible for the tooth's sensitivity to various stimuli such as temperature changes, pressure, or decay. Dentin plays a crucial role in protecting the dental pulp while also providing support and structure to the overlying enamel and cementum.

Tooth loss is the condition or process characterized by the disappearance or absence of one or more teeth from their normal position in the dental arch. This can occur due to various reasons such as tooth decay, periodontal disease (gum disease), injury, or aging. The consequences of tooth loss include difficulties in chewing, speaking, and adversely affecting the aesthetics of a person's smile, which may lead to psychological impacts. Additionally, it can cause shifting of adjacent teeth, bone resorption, and changes in the bite, potentially leading to further dental issues if not treated promptly.

Dental restoration wear refers to the progressive loss of structure and function of a dental restoration, such as a filling or crown, due to wear and tear over time. This can be caused by factors such as chewing, grinding, or clenching of teeth, as well as chemical dissolution from acidic foods and drinks. The wear can lead to changes in the shape and fit of the restoration, which may result in discomfort, sensitivity, or even failure of the restoration. Regular dental check-ups are important for monitoring dental restorations and addressing any issues related to wear before they become more serious.

A tooth germ is a small cluster of cells that eventually develop into a tooth. It contains the dental papilla, which will become the dentin and pulp of the tooth, and the dental follicle, which will form the periodontal ligament, cementum, and alveolar bone. The tooth germ starts as an epithelial thickening called the dental lamina, which then forms a bud, cap, and bell stage before calcification occurs and the tooth begins to erupt through the gums. It is during the bell stage that the enamel organ, which will form the enamel of the tooth, is formed.

A deciduous tooth, also known as a baby tooth or primary tooth, is a type of temporary tooth that humans and some other mammals develop during childhood. They are called "deciduous" because they are eventually shed and replaced by permanent teeth, much like how leaves on a deciduous tree fall off and are replaced by new growth.

Deciduous teeth begin to form in the womb and start to erupt through the gums when a child is around six months old. By the time a child reaches age three, they typically have a full set of 20 deciduous teeth, including incisors, canines, and molars. These teeth are smaller and less durable than permanent teeth, but they serve important functions such as helping children chew food properly, speak clearly, and maintain space in the jaw for the permanent teeth to grow into.

Deciduous teeth usually begin to fall out around age six or seven, starting with the lower central incisors. This process continues until all of the deciduous teeth have been shed, typically by age 12 or 13. At this point, the permanent teeth will have grown in and taken their place, with the exception of the wisdom teeth, which may not erupt until later in adolescence or early adulthood.

A tooth root is the part of a tooth that is embedded in the jawbone and cannot be seen when looking at a person's smile. It is the lower portion of a tooth that typically has a conical shape and anchors the tooth to the jawbone through a periodontal ligament. The tooth root is covered by cementum, a specialized bone-like tissue, and contains nerve endings and blood vessels within its pulp chamber.

The number of roots in a tooth can vary depending on the type of tooth. For example, incisors typically have one root, canines may have one or two roots, premolars usually have one or two roots, and molars often have two to four roots. The primary function of the tooth root is to provide stability and support for the crown of the tooth, allowing it to withstand the forces of biting and chewing.

Dental models are replicas of a patient's teeth and surrounding oral structures, used in dental practice and education. They are typically created using plaster or other materials that harden to accurately reproduce the shape and position of each tooth, as well as the contours of the gums and palate. Dental models may be used for a variety of purposes, including treatment planning, creating custom-fitted dental appliances, and teaching dental students about oral anatomy and various dental procedures. They provide a tactile and visual representation that can aid in understanding and communication between dentists, patients, and other dental professionals.

Tooth eruption is the process by which a tooth emerges from the gums and becomes visible in the oral cavity. It is a normal part of dental development that occurs in a predictable sequence and timeframe. Primary or deciduous teeth, also known as baby teeth, begin to erupt around 6 months of age and continue to emerge until approximately 2-3 years of age. Permanent or adult teeth start to erupt around 6 years of age and can continue to emerge until the early twenties.

The process of tooth eruption involves several stages, including the formation of the tooth within the jawbone, the movement of the tooth through the bone and surrounding tissues, and the final emergence of the tooth into the mouth. Proper tooth eruption is essential for normal oral function, including chewing, speaking, and smiling. Any abnormalities in the tooth eruption process, such as delayed or premature eruption, can indicate underlying dental or medical conditions that require further evaluation and treatment.

"General practice dentistry" is a term used to describe the provision of primary dental care to patients of all ages. A general practice dentist provides a wide range of dental services, including preventative care (such as cleanings and fluoride treatments), restorative care (fillings, crowns, bridges), endodontics (root canals), oral surgery (extractions), periodontics (treatment of gum disease), prosthodontics (dentures, implants), and orthodontics (braces). They also diagnose and manage dental diseases and provide advice on oral health. General practice dentists aim to provide comprehensive and continuous care to their patients, coordinating with other dental and medical professionals as needed.

In medical terms, acids refer to a class of chemicals that have a pH less than 7 and can donate protons (hydrogen ions) in chemical reactions. In the context of human health, acids are an important part of various bodily functions, such as digestion. However, an imbalance in acid levels can lead to medical conditions. For example, an excess of hydrochloric acid in the stomach can cause gastritis or peptic ulcers, while an accumulation of lactic acid due to strenuous exercise or decreased blood flow can lead to muscle fatigue and pain.

Additionally, in clinical laboratory tests, certain substances may be tested for their "acidity" or "alkalinity," which is measured using a pH scale. This information can help diagnose various medical conditions, such as kidney disease or diabetes.

I'm sorry for any confusion, but "Polyethylene" is not a medical term. It is a type of synthetic plastic that is commonly used in various industrial and consumer products. Medical definitions typically refer to substances or conditions related to human health, treatment, or disease processes. If you have any questions related to medical terminology or concepts, I'd be happy to help!

A supernumerary tooth, also known as hyperdontia, refers to an additional tooth or teeth that grow beyond the regular number of teeth in the dental arch. These extra teeth can erupt in various locations of the dental arch and may occur in any of the tooth types, but they are most commonly seen as extra premolars or molars, and less frequently as incisors or canines. Supernumerary teeth may be asymptomatic or may cause complications such as crowding, displacement, or impaction of adjacent teeth, and therefore, they often require dental treatment.

Tooth abnormalities refer to any variations or irregularities in the size, shape, number, structure, or development of teeth that deviate from the typical or normal anatomy. These abnormalities can occur in primary (deciduous) or permanent teeth and can be caused by genetic factors, environmental influences, systemic diseases, or localized dental conditions during tooth formation.

Some examples of tooth abnormalities include:

1. Microdontia - teeth that are smaller than normal in size.
2. Macrodontia - teeth that are larger than normal in size.
3. Peg-shaped teeth - teeth with a narrow, conical shape.
4. Talon cusps - additional cusps or points on the biting surface of a tooth.
5. Dens invaginatus - an abnormal development where the tooth crown has an extra fold or pouch that can trap bacteria and cause dental problems.
6. Taurodontism - teeth with large pulp chambers and short roots.
7. Supernumerary teeth - having more teeth than the typical number (20 primary and 32 permanent teeth).
8. Hypodontia - missing one or more teeth due to a failure of development.
9. Germination - two adjacent teeth fused together, usually occurring in the front teeth.
10. Fusion - two separate teeth that have grown together during development.

Tooth abnormalities may not always require treatment unless they cause functional, aesthetic, or dental health issues. A dentist can diagnose and manage tooth abnormalities through various treatments, such as fillings, extractions, orthodontic care, or restorative procedures.

In medical terms, "fossils" do not have a specific or direct relevance to the field. However, in a broader scientific context, fossils are the remains or impressions of prehistoric organisms preserved in petrified form or as a mold or cast in rock. They offer valuable evidence about the Earth's history and the life forms that existed on it millions of years ago.

Paleopathology is a subfield of paleontology that deals with the study of diseases in fossils, which can provide insights into the evolution of diseases and human health over time.

Tooth extraction is a dental procedure in which a tooth that is damaged or poses a threat to oral health is removed from its socket in the jawbone. This may be necessary due to various reasons such as severe tooth decay, gum disease, fractured teeth, crowded teeth, or for orthodontic treatment purposes. The procedure is performed by a dentist or an oral surgeon, under local anesthesia to numb the area around the tooth, ensuring minimal discomfort during the extraction process.

In the context of dentistry, a molar is a type of tooth found in the back of the mouth. They are larger and wider than other types of teeth, such as incisors or canines, and have a flat biting surface with multiple cusps. Molars are primarily used for grinding and chewing food into smaller pieces that are easier to swallow. Humans typically have twelve molars in total, including the four wisdom teeth.

In medical terminology outside of dentistry, "molar" can also refer to a unit of mass in the apothecaries' system of measurement, which is equivalent to 4.08 grams. However, this usage is less common and not related to dental or medical anatomy.

Prader-Willi Syndrome (PWS) is a genetic disorder that affects several parts of the body and is characterized by a range of symptoms including:

1. Developmental delays and intellectual disability.
2. Hypotonia (low muscle tone) at birth, which can lead to feeding difficulties in infancy.
3. Excessive appetite and obesity, typically beginning around age 2, due to a persistent hunger drive and decreased satiety.
4. Behavioral problems such as temper tantrums, stubbornness, and compulsive behaviors.
5. Hormonal imbalances leading to short stature, small hands and feet, incomplete sexual development, and decreased bone density.
6. Distinctive facial features including a thin upper lip, almond-shaped eyes, and a narrowed forehead.
7. Sleep disturbances such as sleep apnea or excessive daytime sleepiness.

PWS is caused by the absence of certain genetic material on chromosome 15, which results in abnormal gene function. It affects both males and females equally and has an estimated incidence of 1 in 10,000 to 30,000 live births. Early diagnosis and management can help improve outcomes for individuals with PWS.

I believe there may be some confusion in your question as Polyethylenes are not a medical term, but rather a category of synthetic polymers commonly used in various industrial and medical applications. Here's a brief overview:

Polyethylene (PE) is a type of thermoplastic polymer made from the monomer ethylene. It is a versatile material with numerous applications due to its chemical resistance, durability, and flexibility. There are several types of polyethylenes, including:

1. Low-density polyethylene (LDPE): This type has a lower density and more branching in its molecular structure, which results in less crystallinity. LDPE is known for its flexibility and is often used in packaging films, bags, and containers.
2. High-density polyethylene (HDPE): HDPE has a higher density and less branching, resulting in greater crystallinity. It is more rigid than LDPE and is commonly used in applications such as bottles, pipes, and containers.
3. Linear low-density polyethylene (LLDPE): This type combines the flexibility of LDPE with some of the strength and rigidity of HDPE. LLDPE has fewer branches than LDPE but more than HDPE. It is often used in film applications, such as stretch wrap and agricultural films.
4. Ultra-high molecular weight polyethylene (UHMWPE): UHMWPE has an extremely high molecular weight, resulting in exceptional wear resistance, impact strength, and chemical resistance. It is commonly used in medical applications, such as orthopedic implants and joint replacements, due to its biocompatibility and low friction coefficient.

While polyethylenes are not a medical term per se, they do have significant medical applications, particularly UHMWPE in orthopedic devices.

A nonvital tooth is one that no longer has a living or viable pulp, which contains the nerves and blood vessels inside the tooth. This condition can occur due to various reasons such as tooth decay that has progressed deeply into the tooth, dental trauma, or previous invasive dental procedures. As a result, the tooth loses its sensitivity to temperature changes and may darken in color. Nonvital teeth typically require root canal treatment to remove the dead pulp tissue, disinfect the canals, and fill them with an inert material to preserve the tooth structure and function.

An impacted tooth is a condition where a tooth fails to erupt into the oral cavity within its expected time frame, resulting in its partial or complete entrapment within the jawbone or soft tissues. This commonly occurs with wisdom teeth (third molars) but can affect any tooth. Impacted teeth may cause problems such as infection, decay of adjacent teeth, gum disease, or cyst formation, and they may require surgical removal.

Tooth discoloration, also known as tooth staining or tooth color change, refers to the darkening or staining of teeth. It can be categorized into two main types: extrinsic and intrinsic. Extrinsic discoloration occurs when the outer layer of the tooth (enamel) becomes stained due to exposure to colored substances such as coffee, tea, wine, tobacco, and certain foods. Intrinsic discoloration, on the other hand, occurs when the inner structure of the tooth (dentin) darkens or gets a yellowish tint due to factors like genetics, aging, trauma, or exposure to certain medications during tooth development. Tooth discoloration can also be caused by dental diseases or decay. It is important to note that while some forms of tooth discoloration are cosmetic concerns, others may indicate underlying oral health issues and should be evaluated by a dental professional.

A tooth is classified as "unerupted" when it has not yet penetrated through the gums and entered the oral cavity. This can apply to both primary (baby) teeth and permanent (adult) teeth. The reasons for a tooth's failure to erupt can vary, including crowding of teeth, lack of sufficient space, or anatomical barriers such as bone or soft tissue. In some cases, unerupted teeth may need to be monitored or treated, depending on the specific situation and any symptoms experienced by the individual.

An incisor is a type of tooth that is primarily designed for biting off food pieces rather than chewing or grinding. They are typically chisel-shaped, flat, and have a sharp cutting edge. In humans, there are eight incisors - four on the upper jaw and four on the lower jaw, located at the front of the mouth. Other animals such as dogs, cats, and rodents also have incisors that they use for different purposes like tearing or gnawing.

Odontogenesis is the process of tooth development that involves the formation and calcification of teeth. It is a complex process that requires the interaction of several types of cells, including epithelial cells, mesenchymal cells, and odontoblasts. The process begins during embryonic development with the formation of dental lamina, which gives rise to the tooth bud. As the tooth bud grows and differentiates, it forms the various structures of the tooth, including the enamel, dentin, cementum, and pulp. Odontogenesis is completed when the tooth erupts into the oral cavity. Abnormalities in odontogenesis can result in developmental dental anomalies such as tooth agenesis, microdontia, or odontomas.

The term "tooth cervix" is not commonly used in medical dentistry with a specific technical definition. However, if you are referring to the "cervical region of a tooth," it generally refers to the area where the crown (the visible part of the tooth) meets the root (the portion of the tooth that is below the gum line). This region is also sometimes referred to as the "cementoenamel junction" (CEJ), where the enamel covering of the crown meets the cementum covering of the root. Dental issues such as tooth decay, receding gums, or abrasion can affect this area and may require professional dental treatment.

Prosthesis failure is a term used to describe a situation where a prosthetic device, such as an artificial joint or limb, has stopped functioning or failed to meet its intended purpose. This can be due to various reasons, including mechanical failure, infection, loosening of the device, or a reaction to the materials used in the prosthesis.

Mechanical failure can occur due to wear and tear, manufacturing defects, or improper use of the prosthetic device. Infection can also lead to prosthesis failure, particularly in cases where the prosthesis is implanted inside the body. The immune system may react to the presence of the foreign material, leading to inflammation and infection.

Loosening of the prosthesis can also cause it to fail over time, as the device becomes less stable and eventually stops working properly. Additionally, some people may have a reaction to the materials used in the prosthesis, leading to tissue damage or other complications that can result in prosthesis failure.

In general, prosthesis failure can lead to decreased mobility, pain, and the need for additional surgeries or treatments to correct the problem. It is important for individuals with prosthetic devices to follow their healthcare provider's instructions carefully to minimize the risk of prosthesis failure and ensure that the device continues to function properly over time.

Saliva is a complex mixture of primarily water, but also electrolytes, enzymes, antibacterial compounds, and various other substances. It is produced by the salivary glands located in the mouth. Saliva plays an essential role in maintaining oral health by moistening the mouth, helping to digest food, and protecting the teeth from decay by neutralizing acids produced by bacteria.

The medical definition of saliva can be stated as:

"A clear, watery, slightly alkaline fluid secreted by the salivary glands, consisting mainly of water, with small amounts of electrolytes, enzymes (such as amylase), mucus, and antibacterial compounds. Saliva aids in digestion, lubrication of oral tissues, and provides an oral barrier against microorganisms."

Bone conduction is a type of hearing mechanism that involves the transmission of sound vibrations directly to the inner ear through the bones of the skull, bypassing the outer and middle ears. This occurs when sound waves cause the bones in the skull to vibrate, stimulating the cochlea (the spiral cavity of the inner ear) and its hair cells, which convert the mechanical energy of the vibrations into electrical signals that are sent to the brain and interpreted as sound.

Bone conduction is a natural part of the hearing process in humans, but it can also be used artificially through the use of bone-conduction devices, such as hearing aids or headphones, which transmit sound vibrations directly to the skull. This type of transmission can provide improved hearing for individuals with conductive hearing loss, mixed hearing loss, or single-sided deafness, as it bypasses damaged or obstructed outer and middle ears.

I'm sorry for any confusion, but "music" is not a term that has a medical definition. Music is a form of art that uses sound organized in time. It may include elements such as melody, harmony, rhythm, and dynamics. While music can have various psychological and physiological effects on individuals, it is not considered a medical term with a specific diagnosis or treatment application. If you have any questions related to medicine or health, I'd be happy to try to help answer those for you!

Music therapy is a clinical and evidence-based use of music interventions to accomplish individualized goals within a therapeutic relationship by a credentialed professional who has completed an approved music therapy program.

The American Music Therapy Association (AMTA) defines music therapy as the "use of musical experiences, either created or selected, by a trained music therapist to help clients improve or restore physical, psychological, and social functions." The aim is to facilitate positive changes in emotional well-being, cognitive functioning, sensory-motor skills, communication, and quality of life.

Music therapists use various techniques such as singing, playing instruments, listening to music, and discussing lyrics to engage clients in the therapeutic process. These interventions can be tailored to meet the unique needs and preferences of each individual, making it a versatile form of therapy that can benefit people of all ages and abilities.

The ear ossicles are the three smallest bones in the human body, which are located in the middle ear. They play a crucial role in the process of hearing by transmitting and amplifying sound vibrations from the eardrum to the inner ear. The three ear ossicles are:

1. Malleus (hammer): The largest of the three bones, it is shaped like a hammer and connects to the eardrum.
2. Incus (anvil): The middle-sized bone, it looks like an anvil and connects the malleus to the stapes.
3. Stapes (stirrup): The smallest and lightest bone in the human body, it resembles a stirrup and transmits vibrations from the incus to the inner ear.

Together, these tiny bones work to efficiently transfer sound waves from the air to the fluid-filled cochlea of the inner ear, enabling us to hear.

The Scala Tympani is a part of the inner ear's bony labyrinth, specifically within the cochlea. It is one of the two channels (the other being the Scala Vestibuli) that make up the bony duct of the cochlea, through which sound waves are transmitted to the inner ear.

The Scala Tympani starts at the round window, which is a membrane-covered opening located on the cochlea's outer wall. It runs parallel to the Scala Vestibuli and connects with it at the helicotrema, a small opening at the apex or tip of the cochlea.

When sound waves reach the inner ear, they cause vibrations in the fluid-filled Scala Tympani and Scala Vestibuli, which stimulate hair cells within the organ of Corti, leading to the conversion of mechanical energy into electrical signals that are then transmitted to the brain via the auditory nerve.

It's important to note that any damage or dysfunction in the Scala Tympani or other parts of the inner ear can lead to hearing loss or other auditory disorders.

Conductive hearing loss is a type of hearing loss that occurs when there is a problem with the outer or middle ear. Sound waves are not able to transmit efficiently through the ear canal to the eardrum and the small bones in the middle ear, resulting in a reduction of sound that reaches the inner ear. Causes of conductive hearing loss may include earwax buildup, fluid in the middle ear, a middle ear infection, a hole in the eardrum, or problems with the tiny bones in the middle ear. This type of hearing loss can often be treated through medical intervention or surgery.
