clinical comparison of instrumentation time, obturation time and radiographic quality of obturation using the rotary and manual file system for pulpectomy in primary molars

Abstract

Aim:  To evaluate and compare instrumentation time, obturation time, and radiographic quality of obturation using rotary file system and manual file system in primary molar pulpectomy. Materials and Methods: Forty-five primary molars from 42 children aged 5-7 were selected, and divided into 2 Groups : Group I (K-files), Group II (Pro AF Baby Gold Files). Single-visit pulpectomy was performed, instrumentation time and obturation time were recorded during the procedure. Immediate postoperative radiographs were taken and evaluated for obturation quality. The results were tabulated and  subjected to statistical analysis. Results: Pro AF Baby Gold Files (Group II) required least instrumentation time, obturation time and showed superior quality of obturation than K-files (Group I). Conclusion: Pediatric rotary files resulted in superior quality of obturation with minimal chair‐side time, hence they form an integral part of pediatric dentist’s armamentarium and can be considered as the standard of care in primary molar pulpectomies.
