Aims: Condylar region of the mandible is the most vulnerable site to fracture due to its anatomical weakness. It has been noted that mandibular third molars may reduce the occurrence of condylar fractures. This study was conducted to verify this hypothesis. Materials and methods: This retrospective study of records of 147 mandibular fracture patients treated during 5 year period during 2008 to ...

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...

OBJECTIVE The aim of this study was to investigate the root and canal morphology of mandibular first and second molars in a Turkish population by using cone beam computed tomography (CBCT). STUDY DESIGN CBCT images of mandibular first (n = 823) and second molar (n = 925) teeth from 605 Turkish patients were analyzed. The root canal configurations were classified according to the method of Ver...

Impaction of mandibular second permanent molars is a rare occurrence, with prevalence rates reported to be between 0.65% and 2.0%. In the absence of systemic conditions, impactions are usually unilateral. There appears to be no consensus as to the optimal treatment for impacted mandibular second molars and treatment plans will be based upon the individual case. Treatment may involve orthodontic...

A total of 263 ankyloscd primary molars in 107 children aged three to 12 years was studied for four years. Forty-six children remained in the study for eight years. Observation of affected dentitions showed that the condition was likely to recur. Three clinical pa~terns for the condition are described. Typically, maxillary molars became ankylosed earlier and demonstrated more severe in[raocclus...

INTRODUCTION Having knowledge about the anatomy of root canal system is essential for success of endodontic treatment. The present study used cone-beam computed tomography (CBCT), to evaluate the prevalence of third root in mandibular first molars in a selected Iranian population. METHODS AND MATERIALS A total of 386 CBCT images from subjects referred to oral and maxillofacial radiology depar...

BACKGROUND Mandibular first molars typically have two roots but sometimes a supernumerary root presents distolingually called as radix entomolaris (RE). AIM The present study evaluated the prevalence of permanent mandibular first molars featuring a distolingual root in Haryana (North India). MATERIALS AND METHODS Five hundred patients possessing bilateral mandibular first molars were select...

OBJECTIVES The purpose of this study was to evaluate the proximity of the mandibular molar apex to the buccal bone surface in order to provide anatomic information for apical surgery. MATERIALS AND METHODS Cone-beam computed tomography (CBCT) images of 127 mandibular first molars and 153 mandibular second molars were analyzed from 160 patients' records. The distance was measured from the bucc...

statement of the problem using cbct to determine root morphology minimizes rate of treatment failure and adverse effects, such as gouging and perforations. purpose the aim of this study was to assess morphology of root canals using cbct scans. materials and methods in this cross-sectional study, conducted in the radiology department of hamadan dental school in 2011‒2012, 66 cbct scans were stud...

BACKGROUND The objective of this study was to investigate whether multistranded fixed retainers prevented overeruption of unopposed mandibular second molars in maxillary first molar extraction cases. METHODS The panoramic radiographs of 65 Class II Division 1 Caucasian Whites (28 females, 37 males) consecutively treated with bilateral maxillary first molar extraction and the Begg technique, a...
