ABSTRACT
Objective:
To compare the sealing ability and marginal adaptation of three obturation techniques when used in root canal obsturation of c-shaped canals of mandibular second molars.Methods:
Twenty-one extracted mandibular second molars with C-shaped canals were randomly divided into three groups. After instrumentation, the canals were filled using three different techniques ObturaⅡ(group A), cold lateral condensation (group B) and Thermafil (group C). Then, gaps,obturated lateral canals and reticular apical triangles on the X-ray were counted. After dyeing for 7 days in the ink, dyeing lines were measured to reflect the microleakage. The percentages of gutta-percha, sealer and gaps on the root canal surface were determined by analyzing the images of 3 sections per tooth.Results:
The reticular apical triangles were most frequently observed in group C(P
