This study was undertaken on 14 teeth in order to evaluate a new technique for radiation dose reduction during endodontic therapy. After examination of the preoperative film, usually available in the patient file, an apex locator (Root ZX) was used to measure the working length. Complete chemomechanical debridement was then performed, and the master cone was evaluated by a digital imaging syste...

BACKGROUND This systematic review aimed to evaluate the clinical performance of core-carrier obturation in endodontic treatment. METHODS Keywords of "(core carrier OR Thermafil) OR (cold lateral condensation OR lateral condensation) OR (warm vertical condensation OR vertical condensation) AND (obturation OR root canal filling) AND clinical study" were searched for all obtainable publications ...

Article Type: Original Article Introduction: There is a direct relationship between the quality of root canal obturation and success of endodontic therapy. The aim of the present study was to assess the quality of canal obturation performed by undergraduate dental students at the Faculty of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran. Materials and Methods: Records of 200 e...

Successes of endodontic treatment depend on cleaning and shaping of root canal and adequately obturate the prepared root canal space. 1-3 Obturation has historically been achieved with gutta percha and a sealer. The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, anastomoses between canals and a variety of fins. All this leads to...

Irrigation of root canals during endodontic therapy is an important step. Sodium hypochlorite (NaOCl), hydrogen peroxide (H2O2), chlorhexidine (CHX) and normal saline are commonly used intracanal irrigants to disinfect and clean the root canals. This prospective study was set to observe the efficacy of normal saline (0.9% NaCl) irrigation with sequential irrigation of 3% H2O2, 5.2% NaOCl and 0....

PURPOSE This retrospective study evaluated the clinical and radiographic status of nonsurgical endodontic treatment (ET) of anterior and posterior teeth in HIV-seropositive patients. METHODS ET was analyzed in 26 anterior and 34 posterior teeth from 54 consecutive HIV patients (gender ratio 3 Male : 1 Female, mean age 40.2 years, mean CD4 240, CD4<500 in 88%, 12 with AIDS) over a six year per...

Endodontic treatment, when performed with proper instrumentation, canal disinfection, and obturation can be a tremendous service to a dental patient and a key component of any restorative practice. It can be complicated by factors such as poor diagnosis, incomplete canal debridement, ineffective obturation, bacterial invasion, and insufficient restorative treatment. Retreatment or even tooth lo...

This article presents techniques for nonsurgical endodontic retreatment. Issues that influence treatment choice are discussed. Also outlined are armamentaria and techniques for coronal disassembly and removal of obturation materials.

An endodontic Flare-up is defined as an acute exacerbation of asymptomatic pulpal or periapical pathoses after the initiation or continuation of root canal treatment.Pain may be seen after initiating endodontic treatment for a previously asymptomatic tooth or during the course of treatment or after obturation. Establishing the cause of the flare-up is important to initiate the proper treatment....

an important goal in endodontic treatment. To achieve this goal, the root canal filling must seal the pulp space both apically and laterally to prevent further apical irritation from incomplete elimination of bacterial products.1 In the past, the adequacy of root canal filling procedure was primarily based on its vertical appearance on the dental radiograph and whether the material had reached ...
