Background: Pulpotomy is considered to be one of the most commonly preferred treatments in children. Various pulpotomy agents have been used. An ideal pulpotomy agent should be bactericidal, should not damage surrounding tissue. Search for such a pulpotomy agent is still continued.Aim: The objective of this study was to compare and evaluate between two pulpotomy agents i.e. formocresol and ferric sulphate. Material method: A total of 200 primary molars in 100 children were selected for the study. Healthy patients aged between 5 to 9 years were included in the study. Children were randomly assigned to FC group and FS group. Each group consisted of 100 primary molars. FC/FS was placed with a cotton pellet over the pulp stumps for 5 minutes and removed; the pulp stumps were then covered by zinc oxide-eugenol paste. The teeth of both groups were restored with stainless steel crowns. Follow up was done at an interval of 6 and 12 months.Result: Radiographic success rate for FC at 6 month was 93% and FS was 90%. The overall clinical success rate at 12 month interval for FC group was 96.5% and FS group was 96%. Internal resorption was most common radiographical pathology observed.
Conclusion: The overall success rate of present study is lower than those reported by other authors however no significant difference was observed in success rate of both the groups.
