Objective:
To assess the extruded debris apically by the ProTaper Ultimate rotary nickel-titanium files compared to the ProTaper Gold files on preparing the mesiobuccal root canals of mandibular molars.
Methods:
Thirty mandibular molars with mesial canals showing Vertucci Type-IV configuration and curvatures ranging between 20° to 40° were selected and divided into two groups per the rotary files used for root canal shaping (n=15). Myers and Montgomery's methodology was adopted for the collection of debris. The average weight of the collected dried debris was recorded and statistically analyzed using the independent t-test at a significance level of (p<0.05) after log transformation.
Results:
The ProTaper Ultimate showed significantly less debris extruded (2.35+-0.65 mg) than ProTaper Gold (3.25+-0.47 mg) (p=0.001).
Conclusion:
ProTaper Ultimate can efficiently prepare curved root canals with the minimal amount of apical debris extruded compared to ProTaper Gold. (EEJ-2024-06-100).
