1. The infected root canal space cannot be cleaned and disinfected with the standard root canal protocol using an aggressive procedure with endodontic files. 2. After the disinfecting phase of treatment has been completed, filling the root canal is difficult because the open apex provides no barrier for containing the root filling material without impinging on periodontal tissues. 3. Even after...

an accurate diagnosis of the morphology of the root canal system is a pre-requisite for successful root canal treatment. frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have anatomical variations or additional root canals. in this report a maxillary lateral incisor with two roots has been described.

introduction: first branchial cleft anomalies manifest with duplication of the external auditory canal.   case report: this report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. external auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

Background and Aim: Maintaining the original central canal path during cleaning and shaping of the root canal system plays an important role in the success of endodontic treatment. This study sought to compare canal transportation and centering ability of WaveOne and SafeSider rotary files using cone-beam computed tomography (CBCT). Materials and Methods: This in-vitro, experimental study was ...

AIM The purpose of this in vitro study was to analyze the antimicrobial activity of root canal sealers by using the agar diffusion test (ADT). METHODS AND MATERIALS Three categories of root canal sealers were included in the study: resin-based sealers (4), zinc oxide-based sealers (3), and calcium hydroxide-based sealers (2). The microbial strains used were: S. aureus (2 strains), C. albicans...

INTRODUCTION This study investigated the accuracy of cone-beam computed tomography (CBCT), peripheral quantitative computed tomography (pQCT), spiral computed tomography (SCT), plain (plain digi), and contrast medium-enhanced digital radiographs (contrast digi) in studying root canal morphology. METHODS The root canal anatomy was analyzed in 95 teeth using CBCT, pQCT, SCT, plain digi, and con...

INTRODUCTION We investigated the root canal configuration of maxillary premolars in a Spanish population by using cone-beam computed tomography. METHODS Images of 804 maxillary first and second premolars were obtained from 620 patients who underwent cone-beam computed tomography scanning during preoperative assessment (before implant surgery, orthodontic treatment, dentoalveolar trauma diagno...

Introduction: The main goal of root canal treatment is to prevent or heal formation of apical periodontitis. Complexity of root canal anatomy presents clinical challenges related to treatment outcome. The aim of this study was to investigate the morphology of the root canal system of mandibular 2 nd premolar in north Indian subpopulation using periapical radiographs and CT Dentascan. No such st...

A thorough knowledge of root canal morphology is a prerequisite for the endodontic therapy. The maxillary molars, especially the second molars, have the most complicated root canal system in permanent dentition. There are many variations in canal number and configuration in maxillary molars. Treatment may be unsuccessful because the dentist may fail to recognize the unusual canal configuration....

BACKGROUND The chance of discovering foreign object in a root canal is more commonly seen in children. Foreign objects may act as a potential source of infection, which may hinder the complete debridement of root canal. Although the main etiology being an accidental insertion, there are other possibilities such as self-injurious habits which should be ruled out. CASE DETAILS The present artic...
