Clinical and Radiographic Success of Electrosurgical Pulpectomy in Primary Teeth

A pulpectomy requires the swift extraction of the inflamed tissue. Moreover, the speed of treatment is especially important in the case of uncooperative children. Conventional pulpectomies, however, often require an extended treatment period, which can therefore cause problems with such patients. Electrosurgical methods have been applied to pulpotomies for a number of years. However, to the best of our knowledge, no studies to date have assessed its application to pulpectomies. The aim of this study was to compare clinical and radiographic success rates over a 6-month follow-up period between conventional and electrosurgical pulpectomies. A total of 50 children aged 4 to 8 years were enrolled in this randomized clinical trial. A pulpectomy of the first and second primary molar teeth was seen as the optimal treatment plan in all these patients. One group was treated using the conventional method (C group, 25 teeth) and the other with electrosurgery (ES group, 25 teeth). The patients were evaluated for the presence of pain, mobility, abscess, sinus tract, erythema, tenderness to percussion, internal and external root resorption, and radiolucency. Clinical and radiographic success rates and total working time were assessed. The Fisher's exact test and Mann-Whitney U-test were used for the statistical analysis. After 6 months of follow-up, the clinical and radiographic success rates were 90.5 and 85.7%, respectively, in the ES group, compared with 88.9 and 72.2%, respectively, in the C group. No statistically significant difference was observed between the two groups (p>0.05). Working time, however, was significantly shorter in the ES group (p
