This is a rare case report of apexification in an immature permanent mandibular first molar. Calcium hydroxide was used for apical root closure of both the mesial and distal canals. Root closure occurred after 13 months following which obturation of the tooth was completed.

BACKGROUND AND OBJECTIVE To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose...

The main objectives of root canal treatment are thorough shaping and cleaning of all pulp spaces and its complete obturation with an inert filling material. The presence of untreated canal may be a reason for failure of endodontic therapy. To achieve satisfactory root canal therapy, a proper and in-depth knowledge of complex and abnormal root canal morphology is essential.

T he last 10 years have been witness to phenomenal growth in endodontic technology. The introduction of these new technologies has resulted in Endodontics becoming easier, faster, and, most importantly, better. Principle among these is nickel titanium rotary instrumentation that results in consistent, predictable, and reproducible shaping. This predictability of shaping has not only influenced ...

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...

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...

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.
