BACKGROUND Effective pain control in Dentistry may be achieved by local anesthetic techniques. The success of the anesthetic technique in mandibular structures depends on the proximity of the needle tip to the mandibular foramen at the moment of anesthetic injection into the pterygomandibular region. Two techniques are available to reach the inferior alveolar nerve where it enters the mandibula...

In this article, we describe the autotransplantation of a supplemental premolar to replace an extracted first permanent molar in a 12-year-old boy. Although the end results are not ideal due to the small size of the donor tooth, the esthetics and function of the dental arch are partly restored using a natural tooth rather than a prosthesis. This case report illustrates the usefulness of autotra...

Background: One of the most important epidemiologic indices for the assessment and measurement of dental caries is the Decayed, Missing, and Filled Teeth (DMFT) index which is used as an important criterion for the evaluation of the oral and dental health status of individuals. Therefore, the present study was conducted to determine DMFT6 (DMFT of the first permanent molar) index and the relate...

AIM Molar-Incisor Hypomineralisation (MIH) is a congenital disease which increases in prevalence. It affects permanent first molars and, often to a lesser degree, permanent incisors with variable severity. The aetiology is unknown, but different hypotheses have been advanced. Differential diagnosis is mandatory not to confound MIH with other diseases. Treatment consists in a minimally invasive ...

Fifteen patients, eight males and seven females with a mean age of 13.32 years, were selected for unilateral molar distalization. Dentally, all presented with a unilateral Class II molar relationship. The subjects were all in the permanent dentition with second molars erupted and with a well aligned lower dental arch. For maxillary molar distalization a new intra-oral appliance was developed, t...

introduction: the exact measurement of the root canal length is of great importance in root canal therapy. although, determination of the root canal length through radiography is the most common method, recently electronic apex locators are being used to determine working length and decrease the number of radiographs. the purpose of this study was to compare the accuracy of an electronic apex l...

Objective: To evaluate the prevalence of caries in second molar deciduous and adjacent first permanent children. Study Design: Cross Sectional study. Setting: Dental Outdoor Department Ibn-e-Siena Hospital. Period: March 2021 to August 2021. Material & Methods: A total 1,250 patients between age 6-12 years were included study, who free from other dental issues. Consent was taken parents aft...

BACKGROUND A recent study in Canada reported that vitamin D deficiency is associated with dental caries. Because Koreans have been reported to be deficient in vitamin D, we investigated the relationship between dental caries and reduced serum vitamin D levels in Korean children. The purpose of this study was to analyze the relationships between blood vitamin D [25(OH)D] concentrations and denta...

intraosseous migration is an unusual developmental dental anomaly, which demonstrates horizontal movement of unerupted teeth only affecting the permanent dentition of the lower jaw. mandibular second premolar is the most common impacted tooth after the third molars and maxillary canines. distal migration of the second premolar is rare and early loss of the permanent first molar is one of the mo...

PURPOSE To estimate oral and maxillofacial surgery reporting of the frequency of temporary and permanent inferior alveolar and lingual nerve damage from lower third molar extraction and injury etiology, and to identify factors associated with injury rates. MATERIALS AND METHODS A postal survey was sent to all members of the California Association of Oral and Maxillofacial Surgeons requesting ...
