Introduction: Adequate knowledge about the anatomy of the roots and canals of mandibular third molars is imperative for a successful treatment. This study aimed to use cone-beam computed tomography (CBCT) to evaluate the morphology of the roots and canals of mandibular third molars and their symmetry.
Methods And Materials: Totally, 110 CBCT images of bilateral mandibular third molars were evaluated in terms of the number of roots and canals, canal type, isthmus location, location of accessory canals, degree of root curvature and its direction, age and sex of patients and the symmetry of variables in the right and left sides of the mandible.
Introduction:: Knowledge of radicular anatomy has a crucial impact on endodontic practices. Since some anatomic features such as modifications of Vertucci are not evaluated adequately, this study was conducted.
Methods And Materials:: In this study, cone-beam computed tomography (CBCT) images of 312 intact bilateral first molars from 156 patients (79 males and 77 females with an average age of 35.
Background: The value for the use of thyroid shield is one of the issues in radiation protection of patients in dental panoramic imaging.
Objectives: The objective of this research is to investigate the attenuation characteristics of some models of thyroid shielding in dental panoramic examinations.
Methods: The effects of five different types of lead and lead-free (Pb-equivalent) shields on dose reduction of thyroid gland were investigated using implanted Thermoluminescence Dosemeters (TLDs) in head-neck parts of a Rando phantom.
Introduction: Good radiographs are required for endodontic therapy and because some patient's are intolerant to intraoral films and/or sensors, this can cause complications in endodontic treatment. Extraoral film placement can be used to obtain clinically diagnostic and working radiographs.
Materials And Methods: The no.
