Abstract

Aim: The purpose of this randomized clinical trial was to evaluate the intensity and duration of postoperative pain after pulpectomy of primary teeth using three preparation techniques. Materials and methods: A total of 60 patients were randomly allocated to three groups of 20 patients each, according to the root canal instrumentation techniques used. In group I, the teeth were prepared using manual NiTi K flex files till size 35. In group II, the teeth were prepared using NiTi K flex files till size 35 in reciprocating motion. In group III, the teeth were prepared using Kedo-S pediatric rotary files. After root canal preparation, the canals were obturated with endoflas paste and were restored permanently with composite filling material. The intensity and duration of postoperative pain were evaluated after 6, 12, 24, 48, and 72 hours, using a four-point pain-intensity scale. Results: There was a statistically significant difference among the groups, wherein the postoperative pain was more in NiTi K flex files used in reciprocating motion followed by manual NiTi K flex files and Kedo-S pediatric rotary files. Conclusion: Postoperative pain was more with NiTi K flex files in reciprocating motion and was less with Kedo-S rotary files after root canal preparation in primary maxillary molars.
