Efficacy of dentin bonding to cervical defects. (1/76)
The bonding efficacy of sclerotic dentin was determined by measuring the polymerization contraction gap width of a commercial light-activated resin composite in a cervical defect and by measuring the micro-Vicker's hardness at the dentin adhesive surface; morphological characteristics were observed using a scanning electron microscope in extracted human incisors and premolars. Contraction gap formation was completely prevented when the cavity wall was primed with 35 vol% glyceryl mono-methacrylate solution after 0.5 mol/L EDTA conditioning. The contraction gap width was significantly decreased when the resin composite was filled into the sclerotic dentin cavity even when priming was omitted. These results suggest that the sclerotic dentin, which is frequently observed in cervical defects, should be preserved as a substrate because it exhibits an effect of dentin priming and is suitable for bonding. (+info)Anisotropy of tensile strengths of bovine dentin regarding dentinal tubule orientation and location. (2/76)
The purpose of this study was to investigate the effects of the location and orientation of dentinal tubules in the tooth on tensile strengths of the dentin. Dumbbell-shaped specimens of 12 groups from various locations and dentinal tubule orientations were prepared. The tensile test was performed in distilled water at a temperature of 37 degrees C. The tensile strengths of the parallel to the orientation were significantly greater than those of the perpendicular to the orientation; the tensile strengths of the radicular dentin were significantly greater than those of the coronal dentin. Nevertheless, in the radicular dentin, the tensile strengths of the perpendicular to dentinal tubules differ with respect to tensile forces. These results suggest that tensile strength of the dentin varies according to the location and orientation of dentinal tubules in the tooth. (+info)Evaluation of adhesive defects using an ultrasonic pulse-reflection technique. (3/76)
The purpose of this study was to examine the application of an ultrasonic pulse-reflection technique for the evaluation of adhesive defects. First, the sonic velocities in the enamel and dentin of human molars and bovine incisors were measured with a pulsar receiver attached to an ultrasonic transducer. The identification of the dentino-enamel junction and pulp-dentin interface using the ultrasonic method based on intrinsic sonic velocities showed good agreement with the actual measured thicknesses. Next, a cemented restoration with artificial faults was prepared. Half of the Au-Ag-Pd alloy plate area was cemented to the dentin slab using luting resin cement. The adhesive interface was evaluated with a high-resolution ultrasonic imaging system. Clear internal faults were evident from the ultrasonic tomogram. The findings of this study suggest that the ultrasonic pulse-reflection technique may be useful for inspecting and imaging structural defects of adhesive interfaces. (+info)Educational material of dental anatomy applied to study the morphology of permanent teeth. (4/76)
The purpose of this report is to present educational material that would allow the dental student to learn to easily identify the morphologic characteristics of permanent teeth, and how they fit together (occlusion). In order to do this, macro models of permanent teeth with no attrition were carved in wax and later molded with alginate. These molds were filled with plaster, dental stone and/or cold-cured acrylic resin. The large individual dental stone tooth models were mounted on a wax base, thus obtaining maxillary and mandibular arches which were occluded. These dental arches were molded with plaster or dental stone. The authors suggest that these types of macro models allow an excellent visualization of the morphologic characteristics of permanent teeth and occlusion. Dental students are able to carve the permanent dentition in wax with great facility when they can observe macro models. (+info)Anterior tooth morphology and its effect on torque. (5/76)
This study was undertaken to determine the variation in crown-root angle (CRA) of the upper incisors and canines as well as the variation in their labial contour. In addition, the influence of the variability of the labial contour and of different bracket heights on torque was evaluated. Proximal radiographs were taken of 160 extracted maxillary teeth (81 incisors and 79 canines). They were digitized and analysed with Jasc Paint Shop Pro 7TM and Mathcad 2001 Professional. The incisal edge, the centre of the cemento-enamel junction (CEJ), and the root apex were digitized to define the crown and root long axis. For all teeth the CRA was measured. At several heights of the labial surface a tangent was determined, enabling measurement of the inclination of the labial surface. The CRA had great variability, ranging from 167 to 195 degrees for the canines (mean value 183 degrees) and from 171 to 195 degrees for the incisors (average 184 degrees). The mean inclinations of the labial surfaces for the incisors varied greatly. Between 4 and 4.5 mm from the incisal edge the standard deviations (SD) were the smallest and between 2 and 4.5 mm from the incisal edge the labial surface angle differed by approximately 10 degrees. For the canines the mean inclinations of the buccal surface also varied. This angle differed by around 10 degrees between 2 and 4.5 mm from the incisal edge, but the SD were much larger than for the incisors. It can be concluded that placement of a bracket on a tooth at varying heights, still within a clinically acceptable range, results in important differences in the amount of root torque. (+info)Influence of cervical preflaring on determination of apical file size in maxillary premolars: SEM analysis. (6/76)
The purpose of this study was to investigate the influence of cervical preflaring on the determination of the first file that binds at working length (WL) in buccal roots of maxillary premolars. Five groups (n=10) were formed at random and, after standard access cavities, the WL was determined 1 mm short from the apex. In group 1, the initial apical file was inserted without preflaring of cervical and middle thirds of the root canals. In groups 2 to 5, the cervical and middle thirds were enlarged with sizes 90 and 110 Gates-Glidden drills, K(3) Orifice Opener instruments, ProTaper instruments and LA Axxess burs, respectively. Canals were sized manually with K-files, starting with No. 08 K-files inserted passively up to the WL. File sizes were increased until a binding sensation was felt at the WL and the size of the instrument was recorded. Transversal sections of the WL regions were examined under scanning electron microscopy and the discrepancies between the canal diameter and first file to bind at the WL were assessed. Significant differences (p<0.001) were found between the groups. The major discrepancy was found without preflaring (mean 157.8 microm). LA Axxess burs produced the smallest discrepancy (mean 0.8 microm). Gates-Glidden drills and K(3) Orifice Opener instruments showed no significant differences (p>0.05) between their results (83.2 microm and 73.6 microm, respectively). The discrepancy for ProTaper instruments was 35.4 microm on average. In conclusion, the instrument binding technique for determination of the anatomical diameter at the WL was not precise. Preflaring of the cervical and middle thirds improved the determination of the anatomical diameter at the WL, and the type of instrument played a major role. Canals preflared with LA Axxess burs showed a more accurate binding of the files to anatomical diameter. (+info)Increased Young's modulus and hardness of Col1a2oim dentin. (7/76)
Mice harboring the Col1a2(oim) mutation (oim) express dentinogenesis imperfecta. To determine the effect of Col1a2 genotype on tissue mechanical properties, we compared Young's modulus and hardness of dentin in the 3 Col1a2 genotypes. Upper incisors were tested by nanoindentation. Genotype had a significant effect on Young's modulus, but there was not a simple mutant allele dosage relationship. The effect of genotype on hardness did not reach significance. Hardness and Young's modulus were greater near the dento-enamel junction than near the pulp chamber. Greater hardness and Young's modulus values near the dento-enamel junction reflected continued mineralization of the dentin following its initial synthesis. Analysis showed the mechanical data to be consistent with Fourier transform infrared and backscattered electron microscopy studies that revealed increased mineralization in oim bone. Analysis of the data suggests that clinical fragility of teeth in oim mice is not due to deficiencies of hardness or Young's modulus, but may be due to defects in post-yield behavior or resistance to fatigue damage. (+info)Root coverage with free gingival autografts--a clinical study. (8/76)
AIM: To assess the percentage of root coverage with autogenous free gingival grafts. MATERIALS & METHODS: Ten non-smoking patients with Miller's class I or class II recessions were included in the study. The clinical parameters such as recession depth, recession width, probing pocket depth, clinical attachment level and width of the keratinized gingiva were recorded at the baseline, at the end of 1 month, 3 months, and 6 months after the surgical procedure. Autogenous free gingival grafts harvested from the palatal mucosa were used to cover the denuded roots. RESULTS: Four out of ten sites showed 100% root coverage. A mean percentage of 80.3% of root coverage was achieved. (+info)There are several types of tooth loss, including:
1. Anterior tooth loss: This occurs when one or more front teeth are missing.
2. Posterior tooth loss: This occurs when one or more back teeth are missing.
3. Bilateral tooth loss: This occurs when there is a loss of teeth on both sides of the dental arch.
4. Unilateral tooth loss: This occurs when there is a loss of teeth on one side of the dental arch.
5. Complete tooth loss: This occurs when all teeth are missing from the dental arch.
6. Partial tooth loss: This occurs when only some teeth are missing from the dental arch.
Tooth loss can cause various problems such as difficulty chewing and biting food, speech difficulties, and changes in the appearance of the face and smile. It can also lead to other oral health issues such as shifting of the remaining teeth, bone loss, and gum recession.
Treatment options for tooth loss vary depending on the cause and severity of the condition. Some possible treatments include dentures, implants, bridges, and crowns. It is important to seek professional dental care if you experience any type of tooth loss to prevent further complications and restore oral health.
Precancerous changes in the uterine cervix are called dysplasias, and they can be detected by a Pap smear, which is a routine screening test for women. If dysplasia is found, it can be treated with cryotherapy (freezing), laser therapy, or cone biopsy, which removes the affected cells.
Cervical cancer is rare in developed countries where Pap screening is widely available, but it remains a common cancer in developing countries where access to healthcare and screening is limited. The human papillomavirus (HPV) vaccine has been shown to be effective in preventing cervical precancerous changes and cancer.
Cervical cancer can be treated with surgery, radiation therapy, or chemotherapy, depending on the stage and location of the cancer. The prognosis for early-stage cervical cancer is good, but advanced-stage cancer can be difficult to treat and may have a poor prognosis.
The following are some types of uterine cervical neoplasms:
1. Adenocarcinoma in situ (AIS): This is a precancerous condition that occurs when glandular cells on the surface of the cervix become abnormal and grow out of control.
2. Cervical intraepithelial neoplasia (CIN): This is a precancerous condition that occurs when abnormal cells are found on the surface of the cervix. There are several types of CIN, ranging from mild to severe.
3. Squamous cell carcinoma: This is the most common type of cervical cancer and arises from the squamous cells that line the cervix.
4. Adnexal carcinoma: This is a rare type of cervical cancer that arises from the glands or ducts near the cervix.
5. Small cell carcinoma: This is a rare and aggressive type of cervical cancer that grows rapidly and can spread quickly to other parts of the body.
6. Micropapillary uterine carcinoma: This is a rare type of cervical cancer that grows in a finger-like shape and can be difficult to diagnose.
7. Clear cell carcinoma: This is a rare type of cervical cancer that arises from clear cells and can be more aggressive than other types of cervical cancer.
8. Adenocarcinoma: This is a type of cervical cancer that arises from glandular cells and can be less aggressive than squamous cell carcinoma.
9. Sarcoma: This is a rare type of cervical cancer that arises from the connective tissue of the cervix.
The treatment options for uterine cervical neoplasms depend on the stage and location of the cancer, as well as the patient's overall health and preferences. The following are some common treatments for uterine cervical neoplasms:
1. Hysterectomy: This is a surgical procedure to remove the uterus and may be recommended for early-stage cancers or precancerous changes.
2. Cryotherapy: This is a minimally invasive procedure that uses liquid nitrogen to freeze and destroy abnormal cells in the cervix.
3. Laser therapy: This is a minimally invasive procedure that uses a laser to remove or destroy abnormal cells in the cervix.
4. Cone biopsy: This is a surgical procedure to remove a small cone-shaped sample of tissue from the cervix to diagnose and treat early-stage cancers or precancerous changes.
5. Radiation therapy: This is a non-surgical treatment that uses high-energy rays to kill cancer cells and may be recommended for more advanced cancers or when the cancer has spread to other parts of the body.
6. Chemotherapy: This is a non-surgical treatment that uses drugs to kill cancer cells and may be recommended for more advanced cancers or when the cancer has spread to other parts of the body.
7. Immunotherapy: This is a non-surgical treatment that uses drugs to stimulate the immune system to fight cancer cells and may be recommended for more advanced cancers or when other treatments have failed.
8. Targeted therapy: This is a non-surgical treatment that uses drugs to target specific genes or proteins that contribute to cancer growth and development and may be recommended for more advanced cancers or when other treatments have failed.
It is important to note that the choice of treatment will depend on the stage and location of the cancer, as well as the patient's overall health and preferences. Patients should discuss their treatment options with their doctor and develop a personalized plan that is right for them.
Synonyms: supplemental tooth; extra tooth; hyperdontia.
See Also: Tooth; Dentition.
1. Congenital abnormalities: These are present at birth and may be caused by genetic factors or environmental influences during fetal development. Examples include hypodontia (absence of one or more teeth), hyperdontia (extra teeth), or anodontia (absence of all teeth).
2. Acquired abnormalities: These can occur at any time during life, often as a result of trauma, infection, or other conditions. Examples include tooth decay, gum disease, or tooth wear and tear.
3. Developmental abnormalities: These occur during the development of teeth and may be caused by genetic factors, nutritional deficiencies, or exposure to certain medications or chemicals. Examples include enamel hypoplasia (thinning of tooth enamel) or peg-shaped teeth.
4. Structural abnormalities: These are irregularities in the shape or structure of teeth, such as anomalies in the size, shape, or position of teeth. Examples include crowded or misaligned teeth, or teeth that do not erupt properly.
5. Dental caries (tooth decay): This is a bacterial infection that causes the breakdown of tooth structure, often leading to cavities and tooth loss if left untreated.
6. Periodontal disease: This is an inflammatory condition that affects the supporting tissues of teeth, including the gums and bone, and can lead to tooth loss if left untreated.
7. Tooth wear: This refers to the wear and tear of teeth over time, often due to habits such as bruxism (teeth grinding) or acid reflux.
8. Dental anomalies: These are rare, genetic conditions that affect the development and structure of teeth, such as peg-shaped teeth or geminated teeth (two teeth fused together).
These are just a few examples of tooth abnormalities, and there are many more conditions that can affect the health and appearance of teeth. Regular dental check-ups can help detect and address any issues early on to ensure good oral health.
There are different types of tooth wear, including:
1. Attrition: This is the most common type of tooth wear and occurs when the enamel surfaces of teeth rub against each other.
2. Abrasion: This type of wear occurs when the outer layer of enamel is worn away by a foreign object such as a toothbrush or dental appliance.
3. Erosion: This type of wear occurs when acidic substances such as citrus fruits, soda, and sugary drinks dissolve the enamel surface of teeth.
4. Exfoliation: This type of wear occurs when a tooth is lost due to decay, injury, or gum disease, and the surrounding teeth shift to fill the gap.
Tooth wear can cause a range of symptoms including:
* Sensitivity to hot or cold temperatures
* Pain when chewing or biting
* Aesthetic concerns such as chipped or worn-down teeth
* Difficulty speaking or pronouncing certain words
Tooth wear can be prevented or treated by practicing good oral hygiene, avoiding acidic and sugary foods and drinks, using a soft-bristled toothbrush, and visiting the dentist regularly for check-ups and cleanings. In severe cases, dental restorations such as fillings, crowns, or veneers may be necessary to restore the shape, size, and function of teeth.
A tooth that has died due to injury, disease, or other factors and cannot be saved or repaired. A nonvital tooth may require extraction. Also called dead tooth.
The term "nonvital" is used in the medical field to describe something that is not functioning properly or is no longer alive. In the context of dentistry, a nonvital tooth is one that has died and cannot be saved or repaired. This can happen due to injury, disease, or other factors. Nonvital teeth are typically extracted to prevent further infection or complications. The term "dead tooth" is sometimes used interchangeably with "nonvital tooth."
Impacted teeth can cause a range of symptoms including pain, swelling, and infection. If left untreated, impacted teeth can lead to more serious complications such as abscesses or cysts that can damage the surrounding bone and tissue.
Treatment options for impacted teeth depend on the severity of the impaction and may include antibiotics, pain relief medication, or surgical removal of the tooth. In some cases, impacted wisdom teeth may be removed prophylactically to prevent complications from arising in the future.
It's important to note that not all impacted teeth require treatment and your dentist will assess the situation and provide recommendations based on your individual needs.
There are several types of tooth discoloration, including:
1. Extrinsic stains: These are the most common type of tooth discoloration and are caused by factors such as coffee, tea, red wine, and smoking. These stains can be removed with professional cleaning and whitening treatments.
2. Intrinsic stains: These are deeper stains that occur within the tooth itself and can be caused by factors such as fluorosis, tetracycline staining, and overexposure to fluoride during childhood. These stains can be more difficult to remove and may require more advanced treatments such as porcelain veneers or teeth whitening.
3. Age-related discoloration: As we age, our teeth can become naturally more yellow due to the accumulation of calcium and other minerals on the surface of the teeth. This type of discoloration is more common in adults over the age of 40.
4. Trauma: A blow to the mouth or a injury to a tooth can cause discoloration.
5. Disease: Certain medical conditions such as bruxism, gum disease, and enamel defects can also cause tooth discoloration.
Tooth discoloration can be treated with various methods such as teeth whitening, dental bonding, porcelain veneers, and crowns. The choice of treatment depends on the severity and cause of the discoloration. It is important to consult a dentist if you notice any changes in the color of your teeth, as early diagnosis and treatment can help prevent further damage and improve the appearance of your smile.
During the procedure, the dentist will typically use a pair of forceps to grip the tooth and rock it back and forth to loosen it from the surrounding bone and ligaments. Once the tooth is loose, the dentist will use a specialized instrument to extract the tooth from its socket. The socket may be packed with gauze or other materials to help stop any bleeding and promote healing.
Tooth avulsion can be performed under local anesthesia, which numbs the area where the tooth is located, or sedation dentistry, which helps the patient relax and feel more comfortable during the procedure. After the procedure, the patient may need to follow a special post-operative care plan to ensure proper healing and minimize any discomfort or complications.

Some common types of tooth diseases include:
1. Caries (cavities): A bacterial infection that causes the decay of tooth enamel, leading to holes or cavities in the teeth.
2. Periodontal disease (gum disease): An infection of the tissues surrounding the teeth, including the gums, periodontal ligament, and jawbone.
3. Tooth sensitivity: Pain or discomfort when eating or drinking hot or cold foods and beverages due to exposed dentin or gum recession.
4. Dental abscesses: Infections that can cause pain, swelling, and pus in the teeth and gums.
5. Tooth erosion: Wear away of the tooth enamel caused by acidic foods and drinks or certain medical conditions.
6. Tooth grinding (bruxism): The habit of grinding or clenching the teeth, which can cause wear on the teeth, jaw pain, and headaches.
7. Dental malocclusion: Misalignment of the teeth, which can cause difficulty chewing, speaking, and other oral health problems.
8. Tooth loss: Loss of one or more teeth due to decay, gum disease, injury, or other causes.
Prevention and treatment of tooth diseases usually involve good oral hygiene practices such as brushing, flossing, and regular dental check-ups. In some cases, more advanced treatments such as fillings, crowns, root canals, or extractions may be necessary.
This condition is characterized by the formation of new bone tissue around the tooth, which leads to the immobility of the tooth and can cause pain, discomfort, and difficulty in chewing. Tooth ankylosis can be diagnosed through radiographic examination and symptoms such as pain or limited range of motion of the affected tooth.
Treatment options for tooth ankylosis include antibiotics, pain management medications, and surgical intervention to remove the bone adhesions. In severe cases, extraction of the affected tooth may be necessary. Early diagnosis and appropriate treatment can help prevent complications and improve the chances of successful treatment outcomes.
