Introduction: Statement of the Problem: Cleaning and shaping are regarded as the most important aspects of root canal therapy and prerequisite for the success of endodontic treatment. Apical transportations can jeopardize the outcome of treatment due to the significant decrease in the sealing ability of root filling material. The purpose of this study was to evaluate transportation in type II c...

The aim of the study was to determine number and anatomical configuration roots root canals maxillary first second premolars using cone-beam computed tomography scans. n273 CBCT scans were evaluated, obtaining a sample 592 premolars. Root canal anatomy categorized Ahmed´s classification. Data analyzed Pearson’s Chi-squared test. Two present on 157 premolars, one in 132 three 17. Second prese...

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 ...

Purpose: The present study investigated the root canal configuration of maxillary second molars with fusion using micro-computed tomography (micro-CT).
 Materials & Methods: A total 136 fused were scanned tomography. Images transferred to CTAn v.1.18.8 software (Bruker-microCT) obtain three-dimensional models. specimens classified according type. According Vertucci, classification root...

BACKGROUND Together with diagnosis and treatment planning, a good knowledge of the root canal system and its frequent variations is a necessity for successful root canal therapy. The selection of instrumentation techniques for variants in internal anatomy of teeth has significant effects on the shaping ability and cleaning effectiveness. The aim of this study was to reveal the differences made ...

To clarify the anatomical configuration of the spinal column in the adolescent in the supine position, we have studied 10 adolescent (13-17 yr) and 10 adult (26-38 yr) volunteers using magnetic resonance imaging. T1-weighted sagittal midline magnetic resonance images of the spinal column were obtained with subjects in the supine position. The maximum angles of decline of the lumbar spinal canal...
