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 ...

Dens invagination (DI) is a developmental abnormality of teeth which frequently results in a complex internal anatomy of the root canal system. DI type 3 is an anomaly characterized by infolding of enamel and dentin extending into the root apex. This may present difficulties when forming a diagnosis and treatment plan. Many treatment modalities have been presented in case reports for DI type 3,...

BACKGROUND AND OBJECTIVES The aim of this study was to compare internal anatomy between first and second mandibular premolars and to study different percentage variations of root canal morphology of mandibular premolars in Gujarat population based on Vertucci's classification by clearing technique. METHODOLOGY A total of 80 extracted intact permanent mandibular premolars (40 each mandibular f...

INTRODUCTION The purpose of this study was to evaluate the number of distal roots and canals in mandibular first molars and their internal anatomy radiographically within Iranian population. MATERIALS AND METHODS A total of 310 distal roots of mandibular first molars were incorporated in this study and evaluated in terms of number of roots and number and types of canals. Root canal systems we...

INTRODUCTION The purpose of this study was to investigate the root and canal morphology of maxillary first molars with regards to patients' age and gender with cone-beam computed tomography (CBCT). METHODS AND MATERIALS A total of 149 CBCT scans from 92 (67.1%) female and 57 (31.3%) male patients with mean age of 40.5 years were evaluated. Tooth length, presence of root fusion, number of the ...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of canal dryness on the push-out bond strength of two resin sealers (AH-Plus and Adseal) and a bioceramic sealer (Endosequence BC sealer) after canal irrigation with sodium hypochlorite (NaOCl) and chlorhexidine (CHX). METHODS AND MATERIALS A total of 18 extracted human premolars were used. Canals were prepared and were di...

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...

OBJECTIVE To evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an Iranian population by means of Cone Beam CT (CBCT) images. MATERIALS AND METHODS Four hundred CBCT images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. Vertucci's classification was used to evaluate the number of root...

the aim of this case report was to describe the clinical management of an unusual dens invaginatus type 3. a case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. the patient presented with pain and localized swelling. despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. key learning ...
