Abstract
BACKGROUND: A pulpectomy is regarded as the choice modality of treatment for necrotic teeth. The use of hand files, though popular traditionally as a gold standard, may be challenging due to increased chairside time. Postoperative pain is one of the most common complications of pulpectomy and may be unpleasant for a child/pedodontist. Rotary files were found to reduce instrumentation time, reduce apical extrusion, and in turn reduce pain but there is a lack of studies in primary teeth particularly for pediatric and reciprocating file systems. The increased number of options available today makes it a dilemma for the operator to choose a suitable file system. AIM AND OBJECTIVE: The study aimed to evaluate and compare the instrumentation time, postoperative pain, and effect on child's behavior among three groups, i.e., hand K-flex files (group I), pediatric rotary files (group II), and reciprocating files (group III). MATERIALS AND METHODS: A total of 75 primary molar teeth after meeting inclusion criteria were randomly allocated into three groups. During the procedure, step-wise instrumentation time was recorded using a stopwatch. The child's behavior pre- and postoperatively was assessed by an evaluator. The postoperative pain (up to 1 week) was assessed by a questionnaire. RESULTS: < 0.05*). The pre- and postoperative behavior revealed no significant difference. CONCLUSION: The clinical performance of pediatric and reciprocating files was superior, but the choice of file system did not significantly alter behavior.
