The main objective of root canal treatment is thorough mechanical and chemical cleansing of the entire pulp space and to provide an intact hermatic seal. A 30 year-old female patient was referred to the Department of Conservative Dentistry and Endodontic with a chief complaint of acute pain in her right lower back tooth. From the clinical and radiographic findings, a diagnosis of symptomatic ir...

OBJECTIVE The objective of this study is to evaluate the vertical root fracture resistance of endodontically treated teeth obturated with - Tubli-Seal EWT/Gutta-percha, AH Plus/Gutta-percha, Epiphany SE sealer/Epiphany point. STUDY DESIGN Sixty-five single rooted premolars were decoronated and root length was 14 mm for each specimen. Fifty five teeth were enlarged up to ISO size 40 master api...

Research in endodontics has for the most part been primarily focused on the development of the tools and materials most effective in facilitating root canal treatment. The majority of endodontic treatment principles originally evolved on the basis of trial and error; only recently have scientific methods been adopted that identify appropriate clinical strategies. The biological basis for the th...

OBJECTIVE This study evaluated in vitro the influence of an eugenol-based sealer (EndoFill) on the retention of stainless steel prefabricated posts cemented with zinc phosphate and resin-based (Panavia F) cements after different periods of root canal obturation, using the pull-out test. MATERIAL AND METHODS Sixty upper canines were decoronated and the roots were embedded in resin blocks. The ...

A case of orofacial pain and inferior alveolar nerve (IAN) paraesthesia after extrusion of endodontic sealer within the mandibular canal treated with prednisone and pregabalin is described. A 36-year-old woman underwent root canal treatment of the mandibular second right premolar tooth. Post-operative panoramic radiograph revealed the presence of radiopaque canal sealer in the mandibular canal....

Mineral trioxide aggregate (MTA) has been recommended for pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforation and root canal obturation. Since, its introduction in 1993 by Torabinejad numerous studies have been published regarding various aspects of this material. The aim of this review was to consider MTA as root canal sealer and various labo...

Objective. The present study assessed the chemical elements in two novel calcium silicate-containing root canal sealers, BioRoot RCS and Well-Root ST, compared to a calcium silicate-containing root canal sealer that has been on the market for several years, MTA Fillapex, and epoxy resin-based sealer AHPlus. Material and Methods. The sealers were mixed and manipulated according to the manufactur...

objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...

Objective. To compare the efficacy of ProTaper retreatment files in removing three different obturating materials. Study Design. Forty-five human, single-rooted premolars were divided into three experimental groups. Group 1 was obturated with gutta-percha and AH Plus sealer, Group 2 was obturated with gutta-percha and zinc oxide eugenol sealer, and Group 3 was obturated with GuttaFlow. Retreatm...
