Aim and objective: To evaluate and compare the pre- and post-instrumentation canal volume using hand K-files, ProTaper Gold rotary files, Kedo-S rotary files, and One Shape rotary files in primary molars using cone-beam computed tomography (CBCT). Materials and methods: The study was done on 40 primary molars randomly divided into four groups of 10 teeth. Samples were subjected to CBCT scan and image analysis before instrumentation, following which the teeth were instrumented with respective endo files. Post-instrumentation CBCT scan was done and volume of the canal was measured from CEJ to apex. The obtained values were statistically analyzed to find the level of significance using mean, standard deviation. Statistical analysis was further done using one-way ANOVA and a post hoc test. Results: A statistically significant difference was observed in dentin removal by hand K-files when compared with rotary file groups. One Shape files removed less root dentin followed by Kedo-S rotary files, ProTaper Gold rotary files, and hand K-files, respectively. Conclusion: It can be concluded that rotary files, mainly One Shape and Kedo-S files can be used as an acceptable instrument in roots of primary teeth as it shows the least root dentin removal.
