Производитель: "LAP Lambert Academic Publishing"

This study was done to compare and evaluate the quality of obturation in simulated internal resorptive cavities using different gutta percha obturation techniques and also to compare radiographic and stereomicroscopic methods used to evaluate the quality of obturation. Thirty extracted maxillary central incisors were instrumented at the working length to a 50 file. The roots were sectioned transversely with a diamond disc at 7 mm from the anatomical apex. At the opening of the root canal of each section, hemicircular cavities were drilled with a round bur 5 with a stopper. The corresponding root sections were cemented with glue, thus obtaining root canals with similar cavities that simulated internal resorptions. The specimens were randomly separated into three groups of 10 each. The following obturation techniques were evaluated Group A : Hybrid technique (Combination of lateral and vertical compaction) Group B : Ultrasonic compaction (Satellac). Group C : Thermo plasticized... ISBN:9783848447480
