Evaluation of the controlled placement of injected thermoplasticized gutta-percha

Contemporary research points to infection control as the key determinant of endodontic success. While epidemiological surveys indicate that success is most likely in teeth which have been densely root‐filled to within 2 mm of root‐end, it is unclear whether the root canal filling itself is a key determinant of outcome. It is also unclear how different materials and methods employed in achieving a ‘satisfactory’ root filling may impact on outcome. This article provides an overview of current principles and practices in root canal filling and strives to untangle the limited and often contradictory research of relevance to clinical practice and performance.

“…, Olson et al . ) suggested the placement of a master gutta‐percha cone into the apical part of the root canal prior to using the injection technique to prevent extrusion of injected gutta‐percha. The core‐carrier technique, which uses heat‐softened alpha phase gutta‐percha encased around a plastic carrier, provides excellent adaptation of gutta‐percha to the prepared canal walls and irregularities (Gutmann et al .…”

Background: The aim of this study was to compare the apical sealing ability of cold lateral condensation and Obtura II by using fluid filtration method. Methods: Thirty four single-canal mandibular premolars with mature apices and apical curvature less than 20 degrees were selected. For obtaining complete similarity among samples, all teeth were shortened to 15 mm by cutting the remained crown. For canal preparation, the manual step-back technique by K-files was used. The teeth were divided into two experimental groups (each group included 15 teeth), positive controls (n = 2), and negative controls (n = 2). Teeth in group 1 and 2 were obturated with cold lateral condensation and Obtura II, respectively. To allow the sealer to set, all teeth were stored at 100% humidity and 37°C for the next seven days. For measurement of apical leakage, fluid filtration method was used. The amount of leakage in each canal was
