INTRODUCTION The aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (CBCT) in northern Iranian population and also to indicate the thinnest area around root canals. METHODS AND MATERIALS We evaluated CBCT images of 154 first molars and 147 second molars. By evaluating three axial, sagittal and coronal planes of...

AIM: This study aims to investigate effect of mandibular third molars on angulation second and canines.
 MATERIAL AND METHOD: A total 16 patients (10 female, 6 male) were included. All had two panoramic radiographs. available in the first radiograph. The radiograph was taken approximately 124.81 ± 21.63 weeks after one-sided molar extraction. angulations canines measured These evaluated ex...

A total of 139 extracted mandibular second molars were injected with India ink and demineralized. They were made clear and transparent with methyl salicylate, and the anatomy of their canals was studied. It was found that 86.3% of mandibular second molars had two roots, 9.3% had one root, and 4.3% had three roots. Ninety percent of the mesial roots of the mandibular second molars with two roots...

introduction : the purpose of the present study was to evaluate the prevalence of bilateral three-rooted mandibular first and second molars in indian population. materials and methods: a total of 215 patients were screened bilaterally for mandibular first and second molar and 430 samples of periapical radiographs were obtained. the gender, symmetry, and prevalence of three-rooted mandibular fir...

Background and Aim: It is essential to know the internal root canal anatomy to reach a successful root canal debridement and a subsequent successful root canal obturation. Due to the importance of knowing the complexity of mid-mesial (MM) canals and isthmuses and how to deal with these anatomic variations, in this study, we examined the incidence and prevalence of the MM canal and isthmuses in ...

The purpose of this report is to describe the histopathology of radiolucent lesions associated with pulp necrosis in primary molars. Twenty-one carious, previously untreated, primary molars with radiolucent lesions were extracted with forceps under local anesthesia. If a lesion remained attached to the root, the specimen was transferred to 10% neutral buffered formalin. The sockets were gently ...
