AIM: This study aimed to calculate the percentage of touched surfaces and changes in the cross-sectional area of oval-shaped root canals after preparation using (XP-endo Shaper, IRace, and HyFlex CM) rotary systems using AutoCAD software.
MATERIALS AND METHODS: Sixty extracted single-rooted mandibular premolars were collected and divided into three main groups according to the rotary system used (n = 20). Each tooth was impeded in a resin block, coded, sectioned, and photographed under a stereomicroscope, before and after instrumentation. Microphotographs were analyzed using AutoCAD software. Two-way ANOVA was used to evaluate the mean percentage of the touched surface and mean cross- sectional area between the groups and tooth segments, followed by Tukey’s post hoc test for pair-wise comparisons.
RESULTS: The percentage of touched canal walls was significantly different between IRace group and each of XP-endo Shaper and HyFlex CM groups (p < 0.001). A statistically significant difference was recorded for the mean change in the cross-sectional areas of the root canal between IRace group and both HyFlex CM and XP-endo Shaper groups, respectively (p < 0.001). For all groups, there was a significant difference in the change in the cross- sectional area between all segments (coronal, middle, and apical).
CONCLUSIONS: Within the limitations of this study, the XP-endo Shaper and HyFlex CM files had a higher cutting efficiency and maintained better root stability than the IRaCe system by preserving the dentin of the oval root canal. This was observed at all the canal levels in the coronal, middle, and apical segments.
