INTRODUCTION The incidence of oral sinus communications (OSC) following the extraction of an upper third molar remains uncertain. OBJECTIVES The purpose of this study was to determine the incidence of OSC following the extraction of 389 consecutive upper third molars during 2003 in the Master of Oral Surgery and Orofacial Implantology (Barcelona University, Spain). PATIENTS AND METHOD Diffe...

BACKGROUND The relationship between impacted mandibular third molar and mandibular canal is important for removal of this tooth. Panoramic radiography is one of the commonly used diagnostic tools for evaluating the relationship of these two structures. OBJECTIVES To evaluate the accuracy of panoramic radiographic findings in predicting direct contact between mandibular canal and impacted thir...

Background: The third molar is different in many ways from all the other teeth. The aim of this study was to examine how often the third lower molars are chosen as abutment tooth. Methods: A total of 228 OPG was analyzed. The number of lower third molars (M3s) present per person as well as on the right or the left side of the mandible and their relationships, for both males and females were exa...

Impaction of third molar is a common developmental abnormality. However, ectopic impaction of the mandibular third molar in condylar region is an extremely rare condition. This report describes a case of impacted tooth in the mandibular condyle without any associated pathologic condition. Also, this report presents the spatial relationship of the impacted mandibular third molar to the surroundi...

Fractures of the mandibular angle are common and mandibular third molars are frequently implicated in their pathogenesis. The study was done to investigate this cause and effect relationship. The objectives were to measure the relationship between presence and status of mandibular third molar (M3) and mandibular angle fracture. Study design was descriptive. It was carried out in the Department ...

Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth. The mandibular third molar impaction is said to be due to the inadequate space between the distal of the second mandibular molar and the a...

Removal of a maxillary third molar is a common dental procedure, and oral surgeons rarely experience accidental displacement of a maxillary impacted third molar into the maxillary sinus as a complication of this procedure. In the case in which such displacement occurs, the molar is removed via a transantral (Caldwell-Luc) approach through bone removal or window osteotomy of the anterior wall of...

PURPOSE This study was performed to investigate the course of the mandibular canal on panoramic radiography and the visibility of this canal on both panoramic radiography and cone-beam computed tomography (CBCT). MATERIALS AND METHODS The study consisted of panoramic radiographs and CBCT images from 262 patients. The course of the mandibular canal, as seen in panoramic radiographs, was classi...
