Shaping Effects of Three Different Nickel-Titanium Rotary Endodontic File Systems in Root Canals of Mandibular Molars: An Ex-Vivo Study
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 4
Abstract
Introduction: Canal preparation and shaping is one of the major steps in root canal treatment. Study aimed to compare and evaluate the shaping ability of three different rotary Ni-Ti endodontic file systems in root canals of extracted molar teeth. Material and methods: A total of 60 extracted human mandibular first molar teeth with curvature ranging between 15-300 were used in this study. Specimens were embedded in a modified muffle system and sectioned horizontally at three levels before preparation anitind were randomly divided into three experimental groups. Root canal preparation was performed with ProTaper, RaCe and Varitaper Ni-Ti instruments. Cross section images were taken both before and after instrumentation under a stereomicroscope connected to charged couple device (CCD) camera at a fixed position and magnification. Pre and post radiographs and images obtained were analyzed to evaluate the shaping ability (in terms of amount of dentin removed, straightening, transportation and centering ratio) by using image analysis software. The data were analyzed statistically using ANOVA tests. Results: All the systems maintained canal curvature well. Varitaper and RaCe had better centering ratio and least transportation compared to ProTaper (P<0.05) in the apical section. Protaper had higher values of dentin removal (P<0.05) at all levels compared to other file systems. Conclusions: ProTaper removed dentin more, RaCe and Varitaper had better centering and least transportation at all levels,While canals shaped with ProTaper had transportation and less centering ratio at apical level
