The quality of the endodontic obturation is usually evaluated using radiographic images upon completion. Hence; the present study was undertaken for assessing and comparing quality of root canal obturation during Manual and rotary canal preparation technique of root canal therapy. Materials & methods:A total of 50 patients were included in the present study. All the patients were broadly divided into two study groups as follows: Group A: Patients undergoing root canal therapy by manual canal preparation technique, andGroup B: Patients undergoing root canal therapy by rotary canal preparation technique. Preoperative radiographs were obtained. Root canal therapy was carried out in all the patients as per their respective study groups. Evaluation of both pre-treatment and post-treatment radiographs was done for assessing the technical quality of root canal fillings. Results:Length of root canal was adequate in 56 percent of the cases of group A and in 92 percent of the cases of group B. taper of root canal filling was adequate in 64 percent of the patients of group A and 92 percent of the patients of group B. Significant results were obtained while comparing the obturation quality in between the two study groups. Conclusion:Rotary system of root canal therapy provided better quality of obturation in comparison to manual technique. INTRODUCTION The overall technical preparation quality with nickel-titanium (NiTi) rotary instruments is generally better rated than root canal preparation with hand instruments. Modern NiTi instruments for rotary root canal preparation have been shown to be more reliable in terms of preparation faults, the straightening of root canals, and instrument fractures. Hand instrumentation is taught at universities worldwide as the standard basic technique for root canal preparation. 1- 3 The quality of the endodontic obturation is usually evaluated using radiographic images upon completion. Additionally, during the root canal preparation and obturation phases of treatment, clinical criteria can be identified that are essential for achieving an adequate root canal obturation. Several variables affect the technical quality of root fillings, such as the length of the filling material in relation to the radiographic apex, the density of the root filling material (presence of voids), the taper of the canal. Methods used to evaluate the technical outcome of RCT have been based mostly on radiographic evaluation. 4- 6 Hence; the present study was undertaken for assessing and comparing quality of root canal obturation during Manual and rotary canal preparation technique of root canal therapy. Materials & methods The present study was planned for assessing and comparing quality of root canal obturation during Manual and rotary canal preparation technique of root canal therapy. A total of 50 patients were included in the present study. Only those patients were included which were scheduled to undergo root canal therapy for maxillary canine. All the patients were broadly divided into two study groups as follows:
