Statement of Problem: Formocresol has been considered as a popular pulpotomy medicament in the primary dentition for the past 60 years. However, concerns have been raised on its potential toxicity and mutagenicity during recent years. Therefore, many alternatives have been recommended over the years for formocresol as pulpotomy agents in primary teeth.Purpose: The aim of this study was to evaluate the clinical and radiographic success rates of electrosurgery as a pulpotomy technique in pulpotomized primary molar teeth.Materials and method: Forty primary molar teeth were randomly selected and treated using needle shape electrode in an electrosurgical unit as the pulpotomy technique. All teeth were treated in one treatment session. Patients were placed on a recall program and were evaluated clinically and radiographically after 6-12 month follow up period. Any evidences of pain, fistula, swelling, abnormal mobility, furcation radiolucency or pathologic root resorption were considered as criteria for failure of treatment.Results: After 6-12 month observation period, the clinical success rate was found to be 100% while the radiographic success rate was 84.2%. The overall success rate for this type of treatment showed to be 84.2%.Conclusion: Since electrosurgery is a nonpharmacologic, easy to use, rapid and effective technique, it may be recommended as a suitable alternative for formocresol pulpotomy in primary molar teeth.Key words: Pulpotomy- Primary molar teeth- Electrosurgery- Formocresol.
