Efficacy of Two Rotary Ni–Ti Instruments in the Removal of Gutta–Percha for Root Canal Retreatment–an In Vitro Stereomicroscopic Study
Dr. R. K. Tewari, Dr. Sameer Savaliya
Abstract :
30 extracted human single rooted teeth were instrumented with K3 rotary files and filled using lateral compaction of gutta–percha (GP) and AH Plus sealer. The teeth were randomly divided into three experimental groups of 10 specimens each. Removal of gutta–percha was performed with the following devices and techniques: ProTaper Universal rotary retreatment system, Mtwo retreatment files and Hedstrom files. Time to reach working length and to eliminate filling material was also recorded. The specimens were splited longitudinallyfor evaluation of the area of the remaining gutta–percha/sealer under stereomicroscope at 6X magnification. Photographs were taken for further analysis using computer image analysis program. The results were statistically analyzed using ANOVA and Bonferroni test. It was concluded that all test techniques left gutta–percha/sealer remnants within the root canal. The ProTaper Universal rotary retreatment system proved to be an efficient method of removing gutta–percha and sealer from single rooted teeth.
