MANUAL INSTRUMENTATION AND ROTARY TECHNIQUE IN TERM OF INSTRUMENTATION TIME AND QUALITY OF ROOT CANAL OBTURATION IN SINGLE ROOTED TEETH

Objective: Root canal obturation is an essential stage of root canal treatment aimed to seal the root canal in order to prevent future bacterial contamination/ recontamination of the canal space. Aim of this study was to compare the outcomes of manual procedure with rotary technique in term of quality of root canal obturation in patients presented with single rooted teeth.

Study Design: This was a randomized controlled trial study.

Place and Duration of Study: This study was conducted at the Rawal Institute of Health Sciences, Islamabad, for the duration of six months from January 2020 to July 2020.

Materials and Methods: Eighty teeth of male and female patients with ages 20 to 60 years were enrolled and divided equally into two groups. Group I consist of 40 teeth and rotary method was applied. Group II with 40 teeth and manual instrumentation was done. Post obturation radiographs were done to examine the difference in length, density and taper of root canal filling by using T-score. Time taken for instrumentation and canal filling was recorded and compare the findings between both groups. SPSS version 24.0 was used for data analysis.

Results: There were 50 (62.5%) females and 30 (37.5%) male patient’s teeth with mean age 32.25±11.68 years. We found a significant difference in term of obturation quality between both groups with p-value 0.008. In group I, 15 (37.5%) patients had T-score 2 and 20 (50%) had T-score 3 while in group II, 13 (32.5%) patients had T-score 2 and 8 (20%) patients had T-score 3, a significant difference was observed between both techniques with p-value <0.05. Instrumentation time was higher in group II as compared to group I (20.2 min Vs 10.6 min) with p-value <0.05.

Conclusion: Rotary method in term of quality of root canal obturation was better as compared to manual technique.
