a detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. such information is highly dependent upon the ethnicity of the population of interest. lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. the aim of this study was to evaluate external root morphology and root canal a...

Background. The present study aimed to compare the shaping ability of Reciproc Blue instruments with or without the creation of a glide path in simulated S-shaped root canals. Methods. Root canals of thirty #15.02 clear resin S-shaped blocks were dyed using ink and photographed. Then the blocks were randomly divided into 2 groups: group A: Reciproc Blue with glide path created with ProGlider an...

OBJECTIVE The aim of this study was to investigate the root and canal morphology of maxillary third molars in Central India population using cone-beam computed tomography (CBCT) analysis. MATERIALS AND METHODS CBCT images of 116 maxillary third molars were observed, and data regarding the number of roots, the number of canals, and Vertucci's Classification in each root was statistically evalu...

C-shaped canal is one of the most difficult situations with which dentist confronted during endodontic treatment teeth. Recognition unusual variation in configuration critical because it has been established that root a single tapering and apical foramen exception rather than rule. The early recognition these configurations facilitates cleaning, shaping obturation system. “C” configuration, an ...

Introduction: Detailed diagnosis, treatment planning, and successful endodontic require an in-depth understanding of the root canal anatomy its distinguishing features in various ethnic groups.Objective: The aim this study was to C-shaped morphology mandibular second molars Nepalese population by using clinical radiographic analysis.Methods: This descriptive cross-sectional will be designed imp...

case presentation a 30-year-old male patient with a history of severe, throbbing, constant pain in the lower mandibular molars was referred to the department of endodontics of hamedan dental university. the patient’s medical history was noncontributory. the buccal object rule (same-lingual opposite-buccal technique) confirmed the additional root as a distolingual root (radix entomolaris). follo...

Abstract A mammalian petrosal from the Lower Cretaceous Teete locality in Yakutia (Russia) shows a prominent and complex system of venous channels bony wall pars cochlearis surrounding straight cochlear canal. This is distinctive more strongly developed than other petrosals. ridge present on ventral side canal endocast, continuing between fenestra vestibuli cochleae anterior direction. correspo...

OBJECTIVE Because of the great challenges in the diagnosis and treatment of "C" configuration and lack of any systematic information about its occurrence, the purpose of the present study is to determine the prevalence of C shaped root canals in Iranian population. METHODOLOGY An exhaustive search was undertaken to identify published and unpublished researches related to the C-shaped canals b...

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...
