ABSTRACT

Aim: Ideally, root canal shaping should create a continuous tapered preparation from crown to apex while maintaining the original path of the canal and keeping the foramen size as small as practical. The aim of the present study was to compare the canal transportation and centering ability of Rotary ProTaper and Mani Silk files in continuous and reciprocating motion using cone beam computed tomography (CBCT) to find better instrumentation technique for maintaining root canal geometry. Materials and methodology: 60 freshly extracted teeth were divided into 5 group, Group A : Rotary protaper files in continous rotary motion, Group B: Rotary protaper files in reciprocating motion, Group C: Rotary Silk -Mani files in continous rotary motion, Group D: Rotary Silk -Mani files in reciprocating motion, Group E : Hand Protaper(control). Preinstrumention and postinstrumentation CBCT scans were obtained and statistically compared at 1,3,7mm with the ANOVA test and post hoc tukey test. Results: Data suggested that Silk-Mani files in reciprocating motion presented the better centering ability and less canal transportation than protaper files. Conclusion: Silk-Mani files in reciprocating motion have better Centering Ability and less Canal Transportation than hand and rotary protaper files.
