Methods: The sample consisted of 20 subjects (20 left and 20 right mandibular third molars) who underwent pre-operative radiographic evaluation before extraction of impacted mandibular third molars. On panoramic radiographs, the most common high risk injury signs of inferior alveolar nerve (darkening of roots, interruption of white line, deviation of mandibular canal, narrowing of mandibular ca...

A right mandibular first molar requiring root canal treatment was found to have three separate mesial canals. This case demonstrates an extraordinary anatomical configuration and supplements previous reports of the existence of such configurations in mandibular first molars.

Introduction: Considering the importance of avoiding the outcomes of injury to the inferior alveolar nerve and its accessory branches, the present study was conducted with the purpose of determining the frequency of bifid mandibular canals using cone beam computed tomography images in an Iranian population. Materials and methods: In this cross sectional study, 221 CBCT images were evaluated ...

UNLABELLED Many studies have shown that the greatest risk of fracture of the mandibular angle is related to the presence of an unerupted lower third molar, based on the hypothesis that there is a decrease in the area of bone and absorption of the impact in this area, leading some surgeons to indicate its prophylactic removal in patients most exposed to the risk factors of facial trauma. On the ...

BACKGROUND Impaction of the 3rd molar is a high incident problem occurring in up to 73% of young adults in Europe. Appropriate follow-up routines and optimal timing for surgical removal of the 3rd molars can be established in patients judged to be at increased risk of impaction. The purpose of this study was to identify risk factors for mandibular 3rd molar impaction in adolescent orthodontic p...

Tooth distalization is an effective approach for mandibular prognathism. Current distalization devices are bulky and clinically complicated. Here, we designed a novel molar distalization device by using a sliding rod and a microscrew and performed a mechanical analysis and finite element model (FEM) analysis of force distribution and displacement of the upper canine, first and second premolar a...

The mandibular foramen is a landmark for procedures like inferior alveolar nerve block, mandibular implant treatment, and mandibular osteotomies. The present study was aimed to identify the precise location of the mandibular foramen and the incidence of accessory mandibular foramen in dry adult mandibles of South Indian population. The distance of mandibular foramen from the anterior border of ...

One of the most common complications following impacted third molar surgery is alveolar osteitis (AO). Various variables affect the incidence of AO following impacted third molar extraction. The aim of the present study was to evaluate the effect of surgery difficulty on the incidence of AO after impacted mandibular third molar surgery. Patients with the age range of 18-30 years old with at lea...

OBJECTIVE The purpose is to compare temperature rise in the pulp chamber during fabrication of provisional crowns using different materials and on different types of teeth using direct technique. MATERIALS AND METHODS An extracted, sound, caries free maxillary central incisor and a mandibular molar were selected for the study and crown preparations of all ceramic and all metal were done on ce...
