Aim To compare the outcome after 6 months of the application of formocresol (FC) or mineral trioxide aggregate (MTA) during pulpotomy in primary molar teeth. Methodology A maximum of 126 children (aged 5–9 years) with carious primary teeth that required pulpotomy were selected. Following randomization, a standard pulpotomy preparation was undertaken, and the coronal pulp removed and bleeding arrested. In the FC group, cotton balls, soaked in FC, were placed for 5 min, and then the pulp chamber was filled with Zonalin, a pulpotomy agent. In the MTA group, a 1‐mm‐thick paste of MTA was used as a pulpotomy agent. The crowns in both groups were restored with amalgam or glass ionomer. The teeth of 100 patients were evaluated and compared clinically and radiographically after 3 and 6 months. Results No signs of clinical failure were observed at the 3‐ and 6‐month follow‐up appointments in either group. There were no significant differences in the radiographic findings of the teeth and surrounding tissue at the 3‐month follow‐up. However, at the 6‐month follow‐up, significantly more cases ( P = 0.036) with root resorption were seen in the FC group; no cases of resorption occurred amongst the MTA cases. The surrounding tissue showed radiographic signs of post‐treatment disease in four FC cases; none was seen in the MTA cases. Conclusion After 6 months, pulpotomy with MTA was associated with fewer cases of root resorption and post‐treatment disease. MTA appears to be a reliable alternative material for pulpotomy in primary molar teeth.
