Abstract

Objectives: Root canal cleaning and shaping during root canal treatment have been one of the important stages in achieving success The objective of this study was to investigate area and volume changing occurring during shaping of the root canals with three different nickel titanium instrument systems (Race, Hero shaper, Protaper).
Method: In this study, 91 upper first molar teeth were used. Teeth divided randomly into 3 groups. Mesio buccal root of first upper molar teeth were shaped with Race, Hero shaper, and Protaper. The CT images were taken before and after shaping. The taken CT images were transferred to mimics software and 3D models were obtained. On these 3D models, area and volume changes were calculated. Data were subjected to one way Anova. Significance level was set at P= 0.05
Results: No significant difference was found between the volumes calculated on images in terms of the effectiveness of the instruments (P=0.47). No significant difference was found between the areas calculated on images in terms of the effectiveness of the instruments (P=0.71).
Conclusion: Within the limits of this study, all rotary instrument systems showed similar effects in terms of area and volume changes of the root canals at the end of the shaping process.
