Introduction: Pulpectomy has been a treatment of choice in all necrotic primary teeth. With the advancement of technology, the rotary system is developed to reduce skill and enhance the quality of pulpectomy therapy. In paediatric dentistry, new technologies should be leveraged to improve treatment protocols.
Aim: To evaluate and compare the instrumentation time and quality of obturation between the different file systems (Hyflex Controlled Memory (CM), Flexicon X7 and Hedstrom files).
Materials and Methods: In the present randomised clinical trial, a total number of 60 primary molar were selected of healthy children of both sexes from 5-9 years of age attending Department of Pedodontics and Preventive Dentistry at KD Dental College and Hospital, Mathura, Uttar Pradesh during the study period from January 2017 to March 2018. The samples were divided into three groups. Instrumentation was done by using Hedstrom files (H-files) in Group 1; Flexicon X7 in Group 2; Hyflex CM in Group 3; and instrumentation time was recorded in seconds. The quality of obturation was categorised as underfill, optimal fill, and overfill. Statistical analysis was done by using the Chi-square test, ANOVA, and Post-hoc Tukey test with significance level at p<0.05.
Results: In the present study including 60 healthy children, 26 were females and 34 males. Each group consisted of 20 participants each. No significant difference was found with regard to the quality of obturation between the three groups (p=0.519). Flexicon X7 had significantly lesser instrumentation time when compared to that of Hyflex CM and H-file (p<0.001).
Conclusion: The application of the rotary file system in the primary molar significantly reduces the instrumentation time although there was no significant difference noted in the quality of obturation between the different file systems
