Abstract: (289 Views)
Background and Aim: This study assessed the cleaning efficacy of Neolix and M3 Immatural rotary files compared with hand K-files in primary molar root canals.
Materials and Methods: This in vitro study evaluated 40 primary maxillary and mandibular molars. After access cavity preparation, Indian ink was injected into the root canals of primary molars. The teeth were then randomly divided into three experimental and one control group (n=30 canals per group). In group 1, the root canals were instrumented with #20 M3 Immatural file and then with #25/4% to the working length. In group 2, the root canals were instrumented with #25/6% Neoniti A1 file. In group 3, hand K-files were used for instrumentation of the mesial canals of mandibular molars and buccal canals of maxillary molars to #25, and palatal canals of maxillary molars and distal canals of mandibular molars to #30. Group 4 served as the control group and was only rinsed with saline with no instrumentation. After clearing, the teeth were inspected under a stereomicroscope. Data were analyzed by the Kruskal-Wallis and Mann-Whitney U tests.
Results: No significant difference was noted among the groups in cleaning of the coronal third of the root canals (P=0.174). In the middle and apical thirds, two rotary systems showed significantly superior cleaning compared with hand files (P=0.031 and P=0.007, respectively), but there was no significant difference between the two rotary files (P>0.05).
Conclusion: Neolix and M3 Immatural files can serve as efficient alternatives to hand files for pulpectomy of primary molars.
