Background and Objectives: The aim of this study was to assess radiographically the angulations and depth of impacted mandibular third molars. Methods: In a retrospective study 163 impacted mandibular third molars of 100 patients were examined on orthopantomograms (OPT) in the College of Dentistry/ Hawler Medical University during 2008. From these orthopantomograms the angulations (mesioangular...

INTRODUCTION The purpose of this study was to evaluate the number of distal roots and canals in mandibular first molars and their internal anatomy radiographically within Iranian population. MATERIALS AND METHODS A total of 310 distal roots of mandibular first molars were incorporated in this study and evaluated in terms of number of roots and number and types of canals. Root canal systems we...

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.

AIM Prophylactic surgical extraction of impacted third molars is a common practice throughout the world justified on the presumption that the risk of surgical morbidity increases with increasing age, among other reasons. The aim of this study was to analyze and compare surgical morbidity associated with third-molar extractions in young and aging populations. METHODS AND MATERIALS A review of ...

There are many causes of root canal failure, among them the most common cause is undiagnosed canal. Mandibular molars typically have two roots mesial and distal. However, sometimes an additional buccally (radix entomalris) or lingually (paramolaris) may be present. Awareness, diagnosis, biomechanical preparation important for successful outcome therapy. This article presents management mandibul...

AIM To analyse the occurrence of canal isthmuses in molars following root-end resection. METHODOLOGY The material consisted of 56 mandibular and 32 maxillary first molars subjected to periradicular surgery. Based on radiographic, clinical, as well as intraoperative status, only roots with associated pathological lesions were treated. In total, 124 roots were resected (80 mandibular and 44 max...

Objective: The aim of this study was to evaluate the effect of some morphological features of the mandible and mandibular permanent molars on impaction of mandibular third molars with panoramic measurements in a Turkish patient group. Study design: Standardized panoramic radiography variables compiled from 140 patients retrospectively were evaluated. Predictive variables included mesio-distal c...

a case of unusual root morphology is presented to demonstrate anatomic variations in mandibular second molars. the most common configuration of mandibular second molar is to have two roots with three root canals; however mandibular molars may have many different combinations. endodontic therapy was performed in a mandibular second molar with 3 separate roots 2 located mesially and one distally....

Objective. To detect presence of MB2 canal in maxillary molars and distolingual canal in mandibular molars by Dental CT. Material and Methods. A retrospective study of 100 Dental CTs was done. Axial and paraxial images obtained were used to assess the presence of MB2 canal in maxillary molars and distolingual canal in mandibular molars. Results. The youngest patient was of 11 years while the el...
