The identification of agreed criteria for referral following the dental inspection of children in the school setting. (1/688)AIM: To clarify the function of the school based dental inspection. OBJECTIVE: For representatives of the Community Dental Service, General Dental Service and Hospital Dental Service to identify an agreed set of criteria for the referral of children following school dental inspection. DESIGN: Qualitative research methodology used to establish a consensus for the inclusion of referral criteria following dental screening. SETTING: Ellesmere Port, Cheshire, England. MATERIALS: A Delphi technique was used to establish a consensus amongst the study participants on the inclusion of nine possible criteria for referral following dental screening. All participants scored each criterion in the range 1-9, with a score of 1 indicating that referral of individuals with the condition should definitely not take place, and a score of 9 indicating referral should definitely take place. Referral criteria were accepted only if they achieved a group median score of 7 or more, with an interquartile range of three scale points, with the lower value being no less than 7. RESULTS: Four of the nine possible criteria met the agreed group standard for inclusion: 'Sepsis', 'Caries in the secondary dentition', 'Overjet > 10 mm', and 'Registered & caries in the permanent dentition'. CONCLUSION: It is possible to agree clear criteria for the referral of children following the school dental inspection. (+info)

Morphological changes in periodontal mechanoreceptors of mouse maxillary incisors after the experimental induction of anterior crossbite: a light and electron microscopic observation using immunohistochemistry for PGP 9.5. (3/688)Ruffini nerve endings (mechanoreceptors) in the periodontal ligament (PDL) of mouse incisors were examined to elucidate whether experimentally-induced crossbites cause any changes or abnormalities in their morphology and distribution. Anterior guiding planes were attached to the mandibular incisors of 3-week-old C3H/HeSlc mice. At 3 days and 1, 2, 4, 6, and 8 weeks post-attachment of the appliance, the mice were sacrificed by perfusion fixation. Frozen sagittal cryostat sections of the decalcified maxillary incisors were processed for immunohistochemistry of protein gene product 9.5, followed by histochemical determination of tartrate-resistant acid phosphatase activity to reveal sites of alveolar bone resorption. Despite the absence of bone resorption within the lingual PDL of control mice, distinct resorption sites were seen in the respective regions of the experimental animals. Unlike the controls, many Ruffini endings showing vague and swollen contours, with unusually long and pedunculated micro-projections were observed in the affected lingual PDL of the incisors in the experimental animals with short-term anterior crossbite induction. Club-shaped nerve terminations with few, if any, micro-projections were observed in the lingual PDL of experimental animals with long-term induction, as well as in aged control mouse incisors. Differences in the distribution of Ruffini endings were also observed. These results indicate that changing the direction of the force applied to the PDL results in rapid and prolonged changes in the morphology of Ruffini-like mechanoreceptors. (+info)
Motivation for and satisfaction with orthodontic-surgical treatment: a retrospective study of 28 patients. (4/688)Motivation for starting treatment and satisfaction with treatment results were evaluated on the basis of replies to a 14-item questionnaire and clinical examination of 28 orthognathic patients from 6 months to 2 years after treatment. The most common reasons for seeking professional help were problems in biting and chewing (68 per cent). Another major reason was dissatisfaction with facial appearance (36 per cent). Many patients also complained of temporomandibular joint symptoms (32 per cent) and headache (32 per cent). Women (8/19) were more often dissatisfied with their facial appearance than men (2/9), but the difference was not statistically significant. In agreement with earlier studies, the results of orthognathic treatment fulfilled the expectations of almost every patient. Nearly 100 per cent of the patients (27/28) were satisfied with treatment results, although 40 per cent experienced some degree of numbness in the lips and/or jaw 1 year post-operatively. The most satisfied patients were those who stated temporomandibular disorders as the main reason for seeking treatment and whose PAR-index had improved greatly. The majority of the patients experienced the orthodontic treatment as painful and as the most unpleasant part of the whole treatment, but all the patients were satisfied with the pre-treatment information they were given on orthodontics. Orthodontic-surgical therapy should be of a high professional standard technically, but the psychological aspects are equally important in the treatment protocol. The professionals should make efforts to understand the patient's motivations for and expectations of treatment. Patients should be well prepared for surgery and supported for a long time after to help them to adjust to post-surgical changes. (+info)
The functional shift of the mandible in unilateral posterior crossbite and the adaptation of the temporomandibular joints: a pilot study. (5/688)Changes in the functional shift of the mandibular midline and the condyles were studied during treatment of unilateral posterior crossbite in six children, aged 7-11 years. An expansion plate with covered occlusal surfaces was used as a reflex-releasing stabilizing splint during an initial diagnostic phase (I) in order to determine the structural (i.e. non-guided) position of the mandible. The same plate was used for expansion and retention (phase II), followed by a post-retention phase (III) without the appliance. Before and after each phase, the functional shift was determined kinesiographically and on transcranial radiographs by concurrent recordings with and without the splint. Transverse mandibular position was also recorded on cephalometric radiographs. Prior to phase I, the mandibular midline deviated more than 2 mm and, in occlusion (ICP), the condyles showed normally centred positions in the sagittal plane. With the splint, the condyle on the crossbite side was displaced 2.4 mm (P < 0.05) forwards compared with the ICP, while the position of the condyle on the non-crossbite side was unaltered. After phase III, the deviation of the midline had been eliminated. Sagittal condylar positions in the ICP still did not deviate from the normal, and the splint position was now obtained by symmetrical forward movement of both condyles (1.3 and 1.4 mm). These findings suggest that the TMJs adapted to displacements of the mandible by condylar growth or surface modelling of the fossa. The rest position remained directly caudal to the ICP during treatment. Thus, the splint position, rather than the rest position should be used to determine the therapeutic position of the mandible.

A comparison of sagittal and vertical effects between bonded rapid and slow maxillary expansion procedures. (6/688)The purpose of this study was to determine the vertical and sagittal effects of bonded rapid maxillary expansion (RME), and bonded slow maxillary expansion (SME) procedures, and to compare these effects between the groups. Subjects with maxillary bilateral crossbites were selected and two treatment groups with 12 patients in each were constructed. The Hyrax screw in the RME treatment group and the spring of the Minne-Expander in the SME treatment group were embedded in the posterior bite planes, which had a thickness of 1 mm. At the end of active treatment these appliances were worn for retention for an additional 3 months. Lateral cephalometric radiographs were taken at the beginning and end of treatment, and at the end of the retention period. The maxilla showed anterior displacement in both groups. The mandible significantly rotated downward and backward only in the RME group. The inter-incisal angle and overjet increased in both groups. No significant differences were observed for the net changes between the two groups. (+info)
An appraisal of the Peer Assessment Rating (PAR) Index and a suggested new weighting system. (7/688)The PAR Index was developed to measure treatment outcome in orthodontics. Validity was improved by weighting the scores of some components to reflect their relative importance. However, the index still has limitations, principally due to the high weight assigned to overjet. Difficulties also arise from the application of one weighting system to all malocclusions, since occlusal features vary in importance in different classes of malocclusion. The present study examined PAR Index validity using orthodontic consultant assessments as the 'Gold standard' and clinical ranking of occlusal features and statistical modelling to derive a new weighting system, separate for each malocclusion class. Discriminant and regression analyses were used to derive new criteria for measuring treatment outcome. As a result a new and more sensitive method of assessment is suggested which utilizes a combination of point and percentage reductions in PAR scores. This was found to have better correlations with the 'Gold standard' than the PAR nomogram. (+info)
Assessment of clinical case presentations for the Membership in Orthodontics, Royal College of Surgeons of England 1995, 1996. (8/688)The cases presented and treated at successive examinations by the candidates for the Membership Examination in Orthodontics in 1995 and 1996 at The Royal College of Surgeons of England, were of a very high standard and demonstrated a wide range of treatment modalities. All cases had fixed appliances, predominantly with pre-adjusted Edgewise appliances. IOTN confirmed that most cases were in great need of treatment, with PAR scores showing them to be treated to a high standard. (+info)
Malocclusion is a term used in the medical field to describe a misalignment or improper fit of the teeth. It can refer to a variety of conditions, including overbite, underbite, crossbite, open bite, and spacing problems. Malocclusion can be caused by a variety of factors, including genetics, environmental factors, and habits such as thumb sucking or mouth breathing. Malocclusion can lead to a number of problems, including difficulty chewing, speech problems, and jaw pain. Treatment options for malocclusion may include orthodontic appliances such as braces or clear aligners, orthognathic surgery, or a combination of both.
Malocclusion, Angle Class II is a dental condition in which the upper teeth overlap the lower teeth. This type of malocclusion is named after the American orthodontist, Henry H. Angle, who classified malocclusions into different categories based on the relative positions of the upper and lower teeth. In Angle Class II malocclusion, the upper jaw is usually larger than the lower jaw, causing the upper teeth to protrude or stick out. This can result in an "overbite" or "buck teeth" appearance. The severity of the malocclusion can vary, ranging from mild to severe. Angle Class II malocclusion can be caused by a variety of factors, including genetics, jaw growth problems, and habits such as thumb sucking or mouth breathing. Treatment options for Angle Class II malocclusion may include orthodontic braces, clear aligners, or surgery in severe cases. The goal of treatment is to correct the misalignment of the teeth and jaws, improve chewing and speaking functions, and enhance the patient's appearance and self-confidence.
Malocclusion, Angle Class III is a dental condition in which the upper jaw (maxilla) is positioned in front of the lower jaw (mandible) when the teeth are in contact. This type of malocclusion is also known as retrognathism or prognathism, depending on whether the maxilla or mandible is positioned too far forward or backward, respectively. In a Class III malocclusion, the upper teeth may overlap the lower teeth, and the lower jaw may protrude forward. This can cause a number of problems, including difficulty chewing, speech difficulties, and problems with the temporomandibular joint (TMJ). In some cases, a Class III malocclusion may also affect the appearance of the face, leading to a "weak chin" or an overly prominent forehead. Treatment for a Class III malocclusion may involve orthodontic appliances such as braces or clear aligners, or surgery to correct the position of the jaws. The specific treatment approach will depend on the severity of the malocclusion and the individual patient's needs.
Malocclusion, Angle Class I is a dental term used to describe a specific type of misalignment of the teeth. It is one of the three main classifications of malocclusion, the other two being Angle Class II and Angle Class III. In an Angle Class I malocclusion, the upper and lower teeth are aligned in a way that allows the upper front teeth to overlap the lower front teeth when the mouth is closed. This is considered to be the most ideal and natural position for the teeth, as it allows for proper chewing and speaking. However, even in an Angle Class I malocclusion, there may be some degree of misalignment or crowding of the teeth. In these cases, orthodontic treatment may be recommended to correct the alignment and improve the overall appearance of the teeth. It is important to note that malocclusion, Angle Class I is not a medical condition, but rather a dental one. It is typically diagnosed by a dentist or orthodontist and treated with orthodontic appliances such as braces or clear aligners.
In the medical field, an open bite is a type of malocclusion, which refers to a misalignment of the teeth. In an open bite, the upper and lower teeth do not meet properly when the mouth is closed, leaving a gap or space between them. This can occur in both the anterior (front) and posterior (back) regions of the mouth. Open bite can be caused by a variety of factors, including genetics, poor oral habits (such as thumb-sucking or tongue thrusting), dental trauma, or developmental issues. It can also be a symptom of certain medical conditions, such as cleft palate or craniofacial abnormalities. Open bite can affect a person's ability to chew, speak, and breathe properly, as well as their appearance. Treatment options for open bite may include orthodontic appliances, such as braces or retainers, surgery, or a combination of both. The specific treatment approach will depend on the underlying cause of the open bite and the severity of the condition.
In the medical field, diastema refers to a gap or space between the teeth, particularly the front teeth. This gap can occur due to a variety of factors, including genetics, tooth loss, injury, or the presence of a tongue tie. Diastema can affect both the upper and lower teeth and can be present at birth or develop over time. In some cases, diastema may require treatment, such as orthodontic therapy or dental bonding, to improve the appearance and function of the teeth.
In the medical field, overbite refers to a condition where the upper front teeth overlap or protrude beyond the lower front teeth when the mouth is closed. This can cause the lower jaw to appear smaller or receded, and can also lead to problems with chewing, speaking, and biting. Overbite can be caused by a variety of factors, including genetics, poor oral habits, and developmental issues. Treatment options for overbite may include orthodontic appliances, such as braces or retainers, or surgery in severe cases.
Retrognathia is a medical term that refers to a condition in which the lower jawbone (mandible) is positioned behind the upper jawbone (maxilla) in the skull. This can result in a protruding chin or an underbite, and can cause problems with speech, chewing, and breathing. Retrognathia can be caused by a variety of factors, including genetics, developmental issues, and certain medical conditions. It may also be a symptom of other conditions, such as cleft palate or Down syndrome. Treatment for retrognathia depends on the underlying cause and the severity of the condition. In some cases, orthodontic treatment may be used to correct the position of the jawbones and improve the bite. In more severe cases, surgery may be necessary to realign the jawbones and correct the underbite.
Mouth breathing is a condition in which a person breathes primarily through their mouth, rather than through their nose. This can occur due to a variety of factors, including nasal congestion, allergies, a deviated septum, or structural abnormalities in the nose or mouth. In the medical field, mouth breathing can be a sign of an underlying medical condition, such as sleep apnea or chronic obstructive pulmonary disease (COPD). It can also be a symptom of a more serious condition, such as a tumor or foreign object in the nasal passages. Mouth breathing can have a number of negative effects on a person's health, including dry mouth, tooth decay, and snoring. It can also lead to a variety of respiratory problems, such as asthma and bronchitis. Treatment for mouth breathing depends on the underlying cause. In some cases, it may be as simple as using nasal decongestants or saline sprays to relieve nasal congestion. In other cases, more invasive treatments may be necessary, such as surgery to correct structural abnormalities in the nose or mouth.
Dental occlusion, traumatic refers to a type of dental injury that occurs when the teeth come into contact with each other in an abnormal or excessive manner, causing damage to the teeth, gums, or jawbone. This type of injury can be caused by a variety of factors, including accidents, sports injuries, or physical altercations. Symptoms of traumatic dental occlusion may include pain, swelling, difficulty chewing or speaking, and changes in the alignment of the teeth. Treatment for traumatic dental occlusion may involve restorative procedures such as fillings, crowns, or bridges, as well as orthodontic treatment to realign the teeth. In severe cases, surgery may be necessary to repair damage to the jawbone.
Prognathism is a medical term that refers to an abnormal forward projection of the lower jaw, also known as a prognathic jaw. This condition can be caused by a variety of factors, including genetics, hormonal imbalances, and certain medical conditions. Prognathism can affect both the upper and lower jaws, and it can cause a number of symptoms, including difficulty chewing, difficulty speaking, and problems with breathing. In severe cases, prognathism can also cause cosmetic issues, such as an unattractive facial profile. Treatment for prognathism typically involves orthodontic therapy, which involves wearing braces or other appliances to gradually move the jaw into a more normal position. In some cases, surgery may be necessary to correct the condition.
Maxillofacial abnormalities refer to any structural deformities or disorders that affect the bones, muscles, and soft tissues of the face and jaw. These abnormalities can be congenital, meaning present at birth, or acquired later in life due to injury, disease, or other factors. Some common examples of maxillofacial abnormalities include cleft lip and palate, craniosynostosis (premature fusion of skull bones), facial fractures, jaw disorders such as temporomandibular joint (TMJ) disorders, and congenital facial deformities such as micrognathia (underdeveloped jaw) or hemifacial microsomia (one-sided facial weakness). Treatment for maxillofacial abnormalities may involve surgical intervention, orthodontic treatment, or a combination of both. The specific treatment approach will depend on the nature and severity of the abnormality, as well as the individual patient's needs and goals.
Facial asymmetry refers to a condition where there is a difference in the size, shape, or position of facial structures on both sides of the face. This can be caused by a variety of factors, including genetics, injury, or disease. In some cases, facial asymmetry may be noticeable to others, while in other cases it may be subtle and only noticeable to the person affected. In the medical field, facial asymmetry can be a concern for both cosmetic and functional reasons. For example, if the asymmetry is severe enough, it may affect a person's ability to chew, speak, or breathe properly. In these cases, treatment may involve surgery or other medical interventions to correct the asymmetry and improve function.
Tooth abnormalities refer to any deviation from the normal structure, shape, or function of teeth. These abnormalities can be congenital, meaning present at birth, or acquired later in life due to injury, disease, or other factors. Some common examples of tooth abnormalities include: 1. Malocclusion: This refers to an incorrect alignment of the teeth, which can cause problems with chewing, speaking, and overall oral health. 2. Tooth decay: This occurs when bacteria in the mouth produce acid that erodes the tooth enamel, leading to cavities and other dental problems. 3. Tooth sensitivity: This can be caused by a variety of factors, including tooth decay, gum disease, or exposure of the tooth root. 4. Tooth erosion: This occurs when the tooth enamel is worn away due to acid from the stomach or other sources. 5. Tooth discoloration: This can be caused by a variety of factors, including genetics, age, smoking, or certain medications. 6. Tooth abnormalities due to injury: This can include chips, cracks, or fractures in the tooth, as well as missing teeth. 7. Tooth abnormalities due to disease: This can include conditions such as periodontitis (gum disease), which can cause tooth loss, or oral cancer, which can affect the shape and function of the teeth. Treatment for tooth abnormalities depends on the specific condition and may include dental procedures such as fillings, crowns, bridges, or implants, as well as lifestyle changes such as improving oral hygiene habits or quitting smoking.
Bruxism is a medical condition characterized by the involuntary grinding or clenching of the teeth. It is also known as teeth grinding or teeth clenching. Bruxism can occur during the day or at night, and it can be a sign of stress, anxiety, or other underlying medical conditions. The repetitive movement of the jaw and teeth can cause damage to the teeth, gums, and jaw joints, leading to pain, headaches, and other symptoms. Treatment for bruxism may include stress management techniques, mouthguards, or other therapies, depending on the severity of the condition.
Temporomandibular Joint Disorders (TMDs) are a group of conditions that affect the temporomandibular joint (TMJ), which is the joint that connects the lower jaw (mandible) to the skull. TMDs can cause pain, stiffness, and limited movement in the jaw, as well as other symptoms such as headaches, earaches, and neck pain. TMDs can be caused by a variety of factors, including injury, arthritis, teeth grinding or clenching (bruxism), and stress. They can also be related to other medical conditions, such as fibromyalgia or temporomandibular joint ankylosis. Treatment for TMDs depends on the underlying cause and the severity of symptoms. It may include medications, physical therapy, bite guards or splints, and in some cases, surgery. It is important to consult with a healthcare professional, such as an oral and maxillofacial surgeon or a dentist, if you are experiencing symptoms of TMDs.
Anodontia is a medical condition characterized by the absence of teeth in one or more areas of the mouth. It can be a congenital condition, meaning that a person is born without teeth, or it can develop later in life due to injury, disease, or other factors. Anodontia can affect the upper or lower jaw, or both, and can range from mild to severe. In severe cases, a person may have no teeth at all. Anodontia can have a significant impact on a person's ability to chew, speak, and maintain good oral hygiene, and may require treatment such as dental implants or dentures.
Jaw abnormalities refer to any deviation from the normal structure, function, or development of the jawbone or the muscles, ligaments, and joints that control its movement. These abnormalities can be congenital (present at birth) or acquired (developing later in life) and can affect the upper or lower jawbone, or both. Some common examples of jaw abnormalities include: 1. Malocclusion: This refers to an incorrect alignment of the teeth, which can cause problems with chewing, speaking, and overall oral health. 2. Temporomandibular joint disorder (TMJ): This is a condition that affects the joint that connects the jawbone to the skull, causing pain, stiffness, and limited movement. 3. Cleft palate: This is a birth defect that affects the roof of the mouth, causing difficulty with eating, speaking, and breathing. 4. Jawbone abnormalities: These can include conditions such as osteoporosis, which can cause the jawbone to become weak and brittle, or tumors, which can cause the jawbone to grow abnormally. Jaw abnormalities can be treated with a variety of methods, depending on the specific condition and severity. These may include orthodontic treatment, physical therapy, surgery, or a combination of these approaches.
Tooth eruption, ectopic refers to the abnormal position or direction of a tooth as it emerges through the gums. This can occur when a tooth fails to erupt through the correct path, or when it erupts at an angle or in a direction that is not normal for that tooth. Ectopic tooth eruption can be caused by a variety of factors, including genetics, dental trauma, or developmental abnormalities. It can lead to a range of problems, including pain, swelling, infection, and damage to surrounding teeth and tissues. Treatment for ectopic tooth eruption may involve surgical removal of the tooth, orthodontic treatment to guide the tooth into the correct position, or a combination of both.
Facial pain is a medical condition characterized by discomfort or pain in the face, head, or neck. It can be acute or chronic and can be caused by a variety of factors, including injury, infection, inflammation, or nerve damage. There are several types of facial pain, including: 1. Migraine: A type of headache that is often accompanied by other symptoms such as nausea, vomiting, and sensitivity to light and sound. 2. Trigeminal neuralgia: A condition that causes intense, stabbing pain in the face, often triggered by simple activities such as chewing or talking. 3. Temporomandibular joint disorder (TMD): A condition that affects the joint that connects the jaw to the skull, causing pain, stiffness, and difficulty chewing. 4. Cluster headache: A type of headache that occurs in clusters, typically lasting several weeks or months, and is accompanied by symptoms such as redness and watering of the eye. 5. Atypical facial pain: A condition characterized by chronic, non-throbbing pain in the face that is not caused by a specific underlying condition. Treatment for facial pain depends on the underlying cause and can include medications, physical therapy, nerve blocks, and surgery. It is important to seek medical attention if you are experiencing facial pain, as it can be a sign of a more serious underlying condition.
In the medical field, "mesial movement of teeth" refers to the movement of teeth in a direction towards the midline of the mouth. This movement is typically achieved through orthodontic treatment, such as braces or aligners, and is used to correct malocclusions or misalignments of the teeth. Mesial movement of teeth can be used to treat a variety of dental problems, including crowding, spacing, and overbites. It involves the application of force to the teeth in a specific direction, which causes them to move gradually towards the midline of the mouth. This movement can be achieved through the use of brackets and wires, or through the use of clear aligners. Overall, mesial movement of teeth is an important aspect of orthodontic treatment and can help to improve the appearance and function of the teeth and jaw.
Sialorrhea is a medical condition characterized by excessive saliva production or discharge, which can lead to drooling or wetness around the mouth and chin. It can be caused by a variety of factors, including neurological disorders, such as Parkinson's disease or stroke, certain medications, and hormonal imbalances. In some cases, sialorrhea may be a symptom of a more serious underlying condition, such as a head or neck injury, and requires medical attention. Treatment options for sialorrhea may include medications to reduce saliva production, saliva-thickening agents, and behavioral modifications to help manage drooling.
Tooth attrition is the gradual wearing down of the tooth enamel and dentin caused by normal tooth-to-tooth contact during chewing, grinding, or clenching. It is a natural process that occurs throughout a person's life, and it can be accelerated by factors such as bruxism (teeth grinding), acid erosion, and aging. Tooth attrition can lead to a variety of dental problems, including sensitivity, cracking, and even tooth loss. It can also affect the shape and size of the teeth, which can impact the way they fit together and affect the function of the jaw. In some cases, tooth attrition may require dental treatment, such as tooth crowns, fillings, or root canal therapy. Preventive measures, such as wearing a mouthguard during sports or sleep, can also help to reduce the risk of tooth attrition.
In the medical field, a supernumerary tooth is a tooth that is present in addition to the normal number of teeth for an individual. Supernumerary teeth can occur in any part of the mouth, but they are most commonly found in the maxillary (upper) premolar region. Supernumerary teeth can be classified based on their location and shape. The most common types are: 1. Mesiodens: This is a supernumerary tooth that is located between the two central incisors. It is the most common type of supernumerary tooth. 2. Paramolar: This is a supernumerary tooth that is located next to the first molar. 3. Distomolar: This is a supernumerary tooth that is located next to the second molar. 4. Accessory: This is a supernumerary tooth that is located anywhere else in the mouth. Supernumerary teeth can cause a variety of problems, including crowding, misalignment, and impaction. They may also lead to dental caries (cavities) if they are not properly cared for. Treatment options for supernumerary teeth depend on their location, size, and whether they are causing any problems. In some cases, they may need to be removed surgically.
In the medical field, an "impacted tooth" refers to a tooth that is unable to fully emerge from the gums due to a lack of space or obstruction. This can occur in any of the three main types of teeth: incisors, canines, and molars. There are several reasons why a tooth may become impacted. One common cause is a lack of space in the jawbone, which can occur due to genetics or developmental issues. Other factors that can contribute to tooth impaction include cysts, tumors, or other abnormalities in the jawbone. Impacted teeth can cause a variety of problems, including pain, swelling, and infection. In some cases, an impacted tooth may also damage neighboring teeth or lead to gum disease. Treatment options for impacted teeth depend on the severity of the problem and may include extraction, orthodontic treatment, or surgery to remove the obstruction preventing the tooth from emerging.
Facial injuries refer to any type of damage or trauma that affects the structures of the face, including the skin, bones, muscles, nerves, and blood vessels. These injuries can be caused by a variety of factors, such as accidents, falls, assaults, sports injuries, or surgery. Facial injuries can range from minor cuts and bruises to more severe injuries that can result in disfigurement, loss of function, or even death. Some common types of facial injuries include: 1. Fractures: These occur when the bones of the face are broken or cracked. Fractures can be open or closed, and may involve one or more bones in the face. 2. Lacerations: These are deep cuts or tears in the skin that can result from trauma or surgery. 3. Contusions: These are bruises that occur when blood vessels are damaged and blood leaks into the surrounding tissue. 4. Disfigurement: This refers to any type of permanent or temporary damage to the face that results in a change in appearance or function. 5. Nerve damage: This can occur when the nerves that control facial muscles are damaged, resulting in weakness or paralysis of the affected muscles. 6. Dental injuries: These can occur when the teeth are damaged or knocked out as a result of trauma to the face. Treatment for facial injuries depends on the severity of the injury and the specific structures that are affected. Treatment may include surgery, physical therapy, medications, or other interventions to promote healing and restore function.
Temporomandibular Joint Dysfunction Syndrome (TMJDS) is a condition that affects the temporomandibular joint (TMJ), which is the joint that connects the lower jaw (mandible) to the skull. The TMJ is responsible for the movement of the jaw, including opening and closing the mouth, chewing, and talking. TMJDS is a broad term that encompasses a range of symptoms and conditions that affect the TMJ. These can include pain or tenderness in the jaw, difficulty opening or closing the mouth, clicking or popping sounds when the jaw moves, and headaches or ear pain. TMJDS can be caused by a variety of factors, including injury or trauma to the jaw or TMJ, teeth grinding or clenching (bruxism), arthritis, and stress or muscle tension. Treatment for TMJDS may include medications, physical therapy, and in some cases, surgery.
Gingivitis is a common gum disease that affects the gums, which are the tissues that surround and support the teeth. It is caused by the buildup of plaque, a sticky film of bacteria that forms on the teeth and gums. Plaque contains toxins that can irritate and inflame the gums, leading to gingivitis. Gingivitis is usually characterized by red, swollen, and tender gums that bleed easily when brushed or flossed. The gums may also feel sensitive or recede from the teeth. If left untreated, gingivitis can progress to periodontitis, a more severe form of gum disease that can cause tooth loss. Treatment for gingivitis typically involves improving oral hygiene habits, such as brushing and flossing regularly, and using an antiseptic mouthwash. In some cases, a dentist or periodontist may recommend professional cleaning or scaling and root planing to remove plaque and tartar buildup from the teeth and gums.
Dental caries, also known as tooth decay, is a common dental disease that affects the hard tissues of the teeth, including the enamel, dentin, and pulp. It is caused by the demineralization of tooth enamel due to the production of acid by bacteria in the mouth. The bacteria in the mouth feed on sugars and starches in the food we eat, producing acid as a byproduct. This acid can erode the enamel on the teeth, leading to the formation of cavities. If left untreated, dental caries can progress and cause damage to the underlying dentin and pulp, leading to pain, infection, and tooth loss. Dental caries is a preventable disease through good oral hygiene practices, such as brushing and flossing regularly, using fluoride toothpaste and mouthwash, and limiting sugary and acidic foods and drinks. Early detection and treatment of dental caries can help prevent more serious complications and maintain good oral health.
Cleft lip is a birth defect that affects the upper lip and is characterized by a gap or split in the lip. It can occur on one or both sides of the lip and may also involve the nose. Cleft lip can be a isolated condition or may be associated with other birth defects, such as cleft palate or cleft palate and lip. It is typically diagnosed at birth or soon after and can be treated with surgery to repair the lip and, if necessary, the nose. Cleft lip can have a significant impact on a person's appearance and speech, and may also affect their ability to eat and drink.
Craniosynostosis is a medical condition in which one or more of the sutures (the joints between the bones of the skull) close prematurely, causing the skull to become misshapen. This can lead to a variety of problems, including increased pressure on the brain, difficulty breathing, and vision and hearing problems. Craniosynostosis can be caused by a variety of factors, including genetics, injury, and certain medical conditions. It is typically diagnosed through imaging tests such as X-rays or CT scans, and treatment may involve surgery to correct the skull's shape and relieve pressure on the brain.
Tooth loss, also known as edentulism, is a condition in which one or more teeth are missing from the mouth. This can occur due to a variety of factors, including tooth decay, gum disease, injury, or genetics. Tooth loss can have a significant impact on a person's ability to chew and digest food, as well as their overall oral health and appearance. In some cases, tooth loss may require the use of dental implants, dentures, or other restorative treatments to replace the missing teeth.
In the medical field, tooth injuries refer to any damage or trauma that affects the structure, function, or appearance of the teeth. Tooth injuries can occur as a result of accidents, sports injuries, falls, or other types of physical trauma. There are several types of tooth injuries, including: 1. Fractures: A fracture is a crack or break in the tooth that can occur anywhere along the tooth's length. 2. Chips: A chip is a small piece of tooth that has been broken off. 3. Cracks: A crack is a long, narrow break in the tooth that can extend from the surface to the root. 4. Luxation: Luxation occurs when the tooth becomes dislodged from its socket. 5. Avulsion: Avulsion is a severe type of tooth injury in which the tooth is completely knocked out of the socket. Tooth injuries can cause pain, swelling, and difficulty chewing or speaking. In some cases, they may also lead to infection or other complications if left untreated. Treatment for tooth injuries may include restorative procedures such as fillings, crowns, or root canal therapy, as well as surgery in severe cases.
Craniofacial abnormalities refer to any structural deformities or disorders that affect the development or function of the skull, face, and associated structures. These abnormalities can be present at birth (congenital) or may develop later in life due to injury, disease, or other factors. Examples of craniofacial abnormalities include cleft lip and palate, craniosynostosis (premature fusion of skull bones), microcephaly (abnormally small head), craniofacial dysostosis (disorders affecting the development of the skull and facial bones), and facial paralysis. Craniofacial abnormalities can have a significant impact on an individual's physical appearance, speech, hearing, and overall quality of life. Treatment options may include surgery, orthodontics, speech therapy, and other interventions depending on the specific condition and severity.
Cleft palate is a birth defect that affects the roof of the mouth, causing a split or cleft in the palate. The palate is the bony structure that separates the mouth from the nasal cavity. In a cleft palate, the roof of the mouth is not fully formed, leaving a gap or opening that can affect speech, eating, and breathing. There are two types of cleft palate: non-syndromic and syndromic. Non-syndromic cleft palate occurs on its own and does not have any other associated medical conditions. Syndromic cleft palate is associated with other medical conditions, such as Down syndrome or Pierre Robin syndrome. Cleft palate can be repaired through surgery, typically performed in infancy or early childhood. The surgery involves closing the gap in the palate and reconstructing the surrounding tissues. Speech therapy may also be necessary to help the child learn to speak clearly.
Root resorption is a dental condition in which the root of a tooth becomes shorter or disappears due to various factors. It can occur in both primary (baby) and permanent teeth and can be caused by a variety of factors, including trauma, orthodontic treatment, dental procedures, and certain medical conditions. In some cases, root resorption may be asymptomatic and may not cause any noticeable symptoms. However, in severe cases, it can lead to tooth sensitivity, pain, and even tooth loss. Root resorption can be diagnosed through dental X-rays, which can show the extent and severity of the condition. Treatment options depend on the cause and severity of the root resorption, and may include observation, root canal therapy, or extraction of the affected tooth.
