Evaluation of Quality of Obturation Using Two Different Rotary Files and Hand Files in Primary Teeth: A Randomized Controlled Trial

AIM AND OBJECTIVE: To estimate the obturation quality and instrumentation time on comparing traditional hand files and two rotary file types during root canal instrumentation in deciduous molars. MATERIALS AND METHODS: Forty-five deciduous mandibular molars were taken and randomly allotted to three groups (n = 15). Group I: K-hand files, group II: ProTaper Gold rotary file, and group III: Kedo-SG Blue rotary files. Before and after root canal instrumentation, standardized digital radiography was taken and the instrumentation time was also noted. The recorded data were then subjected to statistical analysis utilizing SPSS Software version 22.0. To compare the instrumentation time and quality of obturation between the groups, a Chi-square test and ANOVA with the level of significance at 0.05 were employed. RESULTS: There was no significant difference recorded with reference to the quality of obturation (p > 0.05). However, the difference was noticed to be statistically significant when the instrumentation time between the two rotary groups and the manual instrumentation groups was taken into account (p < 0.05). The rotary systems ProTaper Gold and Kedo-SG Blue exhibited a significantly less instrumentation time on comparing with that of the hand files. CONCLUSION: Concerning the quality of obturation, all three file groups demonstrated almost a similar performance. However, there was a significant difference noticed in the instrumentation time with the use of manual instrumentation in comparison to rotary instrumentation in deciduous teeth.
