Abstract
Background: Comparing shaping ability of Azure and Fanta AF One in rotation and reciprocation. This study was conducted on 40 resin blocks, having canal curvatures 30°-angle and of 16-mm length. The blocks were assigned to 4-groups according to the instrument and motion used: Azure/Rotation (A/Rt), Fanta AF one/Rotation (F/Rt), Azure/ Reciprocation (A/Rec) and Fanta AF one/Reciprocation (F/Rec). For both systems single file 25, taper 0.06 were used. Digital images were taken before and after instrumentation. Adobe Photoshop was used to overlap post and pre- instrumentation images to assess canal transportation at 1, 4, 7-mm; representing apical, middle and cervical levels respectively. Stopwatch was used to document the time taken for canal preparation. One-way ANOVA followed by Tukey post hoc test, used to compare between more than two groups in non-related samples.
Results: At the apical level, no statistically significant difference was found between both files in either rotation or reciprocation. However, reciprocation motion showed significantly lower transportation levels in both files. No signifi- cant difference was found among groups at the middle and cervical levels. Regarding preparation time, Reciprocation in both groups was significantly longer.
Conclusions: The use of reciprocation motion showed minimized apical canal transportation in both files however in longer preparation time.
