Abstract

Objective: The study aimed to reveal the influence of different root canal instrumentation methods (manual and rotary) on the features of root canal obturation, as well as determine which method gives the superior quality of obturation.
Methods: A total of 165 case sheets of endodontically treated teeth (incisors, canines, and single-rooted premolars) were included in our samples from the outpatients in the University of Sulaimani, College of Dentistry, each with the radiograph of the treated tooth attached to it. The case sheets were separated into manual and rotary groups. The evaluation was done for three parameters (homogeneity, taperness and length of filling material).
Results: The results show a statistically significant (p < 0.05) relationship between manual and rotary instrumentation regarding all three parameters evaluated. There is a higher ratio of adequate length of filling material, adequate homogeneity, and adequate taperness in rotary instrumentation than in manual instrumentation.
Conclusions: This study concludes that rotary NiTi instrumentation improves the quality of root canal obturation regarding the 3 parameters. The findings advocate for the inclusion of rotary NiTi instruments in the undergraduate dental curriculum to enhance endodontic treatment outcomes. In the future, more resources are needed regarding the homogeneity of the obturation by different instrumentation and obturation techniques.
