COMPARATIVE ANALYSIS OF PREPARATION OF ROOT CANAL SYSTEMS WITH EITHER HAND OR ROTARY INSTRUMENTS: AN IN VITRO STUDY
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 5
Abstract
Background: NiTI rotary files in comparison to hand instruments (K-files) aid in endodontic procedure by making the procedure easier and more precise, conserving root structure in curved canals, and achieving even conical shape of the canal in lesser time. So, the present study was planned to analytically compare the root canal preparation systems with either hand or rotary instruments. Material and methods: For the study, 40 extracted teeth were selected. The total teeth were randomly grouped into two groups, Group1 and Group 2. Root canals of teeth in Group 1 were prepared using conventional method (stainless steel hand K-files) whereas in Group 2 were prepared using rotary method (NiTi Profile 0.04 taper). Different elements were recorded i.e. Preparation time and root canal blockage. Results: The mean preparation time for K-files was 8.13 minutes and for Protaper files was 9.21 minutes. These results were statistically significant with p-value less than 0.05. In case of K-files we observed 15% blocked canals and 85% patent canals. In comparison to this, Profiles showed 5% blocked canals and 95% patent canals. These results were statistically insignificant with p value greater than 0.05. Conclusion: From the results of the present study, we evaluated that the mean preparation time for canals was less in case of K-files as compared to Protaper NiTi rotary files. But, the incidence of canal blockage was more in case of K-files as compared to Protaper NiTi rotary files.
