introduction : proper apical seal and obturation density are essential to long-term success of root canal therapy (rct). the apical seal and density of lateral compaction techniques using stainless-steel and nickel-titanium spreaders and vertical compaction with beefill device were compared in this in vitro study. materials and methods: a total of 66 extracted maxillary central incisors were in...

BACKGROUND Success in root canal treatment is achieved after thorough biomechanical preparation followed by complete obturation of the canal system together with prompt and adequate restoration. Therefore, the endodontic therapy requires specific and complete knowledge of the internal and external anatomy, and its variation in presentation. Such treatment may be performed in root canal systems ...

OBJECTIVE To evaluate the amount of apically extruded debris during retreatment (with or without solvent) of root canals filled by two obturation techniques. MATERIALS AND METHODS Forty-eight root canals were prepared using ProTaper Universal F3 and filled with Gutta-percha and AH 26 sealer using single cone or lateral condensation techniques. The root canal fillings were removed using ProTap...

INTRODUCTION One of the key factors in successful endodontic therapy is to adequately fill the root canals. The aim of this in vitro study was to compare the quality of four different root canal obturation techniques: cold lateral condensation (CLC), warm vertical condensation (WVC), Obtura II (OII) and Gutta Flow (GF) by using micro-computed tomography (micro CT). MATERIALS AND METHODS A tot...

Introduction: Working length determination is important in successful endodontic treatment and retreatment.This study evaluated the accuracy of two electronic apex locators Root ZX and Raypex®6 (EALs) in determining the electronic working length (EWL) of the root canals in endodontic treatment and retreatment. Materials and Methods: Access cavities were prepared on forty extracted, singl...

PURPOSE To evaluate the efficacy of different obturation techniques in root canals instrumented either by hand or rotary instruments with regard to the percentage of gutta- percha-filled area (PGFA). MATERIALS AND METHODS One hundred and sixty extracted mandibular premolars with single, straight root canals were studied. Root canals were prepared to an apical size of 30 by hand with a modifie...

Success in root canal treatment is achieved after thought cleaning and shaping followed by the complete obturation of root canal system. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. This article describes the conventional root canal treatment on an unusual mandibular second molar with four root-canals.

BACKGROUND The quality of academic training can best be analyzed by including the student's perceptions. The aim of this study is to evaluate the short comings in preclinical endodontic training and also to find out key areas to stress upon for better student understanding and treatment outcome. MATERIALS AND METHODS A total of 72 structured questionnaires were distributed to the dental stude...

The aim of this study was to evaluate the technical quality of root canal treatment carried out by house surgeons at a dental teaching hospital in Islamabad. Radiographic records of the 64 root canal treated teeth of patients were analyzed to find the adequacy of treatment they received. The final sample consisted of 60 teeth. Root treatment was considered adequate if the apical length of obtur...
