statement of problem: perforations are significant complications that can occur during root canal therapy and may result in the destruction of adjacent periodontal tissues. an ideal material for repairing a perforation should be biocompatible and have a high sealing ability. purpose: the aim of this study was to compare histologic tissue responses of experimentally induced pulp chamber perforat...

introduction: knowledge of the anatomic location and dimension of the molar pulp chamber may preserve healthy pulp during operative procedure and reduce risk of perforation of chamber during access preparation. a review of literatures regarding the morphology of pulp chamber however revealed very little information; so the aim of this in vivo study was to measure the dimensions of first molar p...

iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. the present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (cem) cement. the perforation was chemically cleaned and then physical...

UNLABELLED Root perforation is an unwanted incident which may occur at any stage of endodontic treatment and can adversely affect tooth prognosis. AIM To compare the recovery rate after treatment of root perforations in the interradicular area of the molars, using two different materials: MTA and ceramic nanoparticles mineral cement DiaRoot BioAggregate, by a clinical-radiological and statist...

BACKGROUND Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. CASE REPORT Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical lo...

OBJECTIVE This study was designed to investigate radiographically the effects of age and external irritating stimuli on the morphology and thickness of the pulp chamber ceiling and floor in mandibular molars. MATERIALS AND METHODS A total of 234 panoramic radiographs were recruited and 494 mandibular molars were examined in this study. The sample was divided into six age groups: Group 1, <20 ...

taurodontism is a morphologic feature of generally multi-rooted teeth with large pulp chambers and shortened roots. a case of endodontic treatment in a 24-year-old male with the chief complaint of swelling and pain in the right mandibular region is described. periapical lesion was present in the radiographic examination of hypertaurodont second mandibular molar. four root canals were detected w...

INTRODUCTION The conventional method of teaching endodontics has some drawbacks. Due to the small size of the oral cavity, students cannot closely observe the clinical procedure. Use of new teaching modalities such as the intraoral camera may obviate this problem. This study assessed the effect of video-assisted clinical instruction in dentistry (VACID) on dental student's knowledge and perform...
