Abstract

Introduction:

Pulpectomy has been a treatment of choice in all necrotic primary teeth. Advancing technology has brought the rotary system to reduce the manual dexterity and improve the quality of treatment for pulpectomy. Advancing technology in pediatric dentistry should be used for the better treatment protocol.

Aim:

The aim of this study is to compare the obturation quality and instrumentation time after root canal instrumentation with rotary Kedo-S files, hand K-files, and H-files in primary molars.

Materials and Methods:

A randomized control trial where pulpectomy was performed on 75 primary molars equally distributed for instrumentation with K-file, H-files rotary Kedo-S files, respectively. The instrumentation time and obturation quality were noted.

Results:

Kedo-S files showed the least instrumentation time with better obturation quality as compared to other two groups (P < 0.001).

Conclusion:

Pediatric rotary files Kedo-S has better obturation quality in minimum instrumentation time.

KEYWORDS:
