BackgroundPulpotomy is the common therapy for cariously exposed pulps in symptom-free primary molar teeth. Formocresol (FC) is considered the gold standard dressing agent for pulpotomy, but concerns have been raised over the years about its safety. Other alternative pulpotomy agents have been investigated and suggested.ObjectiveThe objective was to evaluate and compare the clinical and radiographic response of FC and white mineral trioxide aggregate (MTA) as pulpotomy materials on primary molars.Materials And MethodsFifty primary molars, with deep carious lesion that exposed a vital but asymptomatic pulp, in 37 children aged 4-7 years were treated with conventional pulpotomy procedure. The teeth were divided randomly into two groups. Group I (FC) and group II (MTA). The treated teeth were evaluated clinically and radiographically and were followed-up for 12 months.ResultsAt the end of the 12 months follow-up, the clinical success rates for FC and MTA were 81% and 100%, respectively. There was a statistically significant difference ( P = 0.04) between the clinical success rates of FC and MTA. While the radiographic success rates for FC and MTA were 81% and 96%, respectively, there was no statistically significant difference between the radiographic success of MTA and FC.ConclusionWhite MTA showed a higher clinical and radiographic success rate when compared to FC as a pulpotomy agent in vital primary molars, and it has a potential to become a replacement for FC in primary molars.
