Objective: To compare the cutting efficiency of twisted files with protaper files in primary teeth.
Study design: It is an experimental, in vitro study comparing two groups.
Results: The obtained results from the experiment were statistically analyzed with Mann-Whitney U-test. Twisted files showed better cutting efficiency when compared to protaper files.
Conclusion: Since twisted files show a better cutting efficiency, they can be efficiently incorporated into the contemporary pediatric endodontic armamentarium.
