Background: Pulpotomy is the most accepted therapy for the management of cariously exposed pulps in symptom-free primary molars. Formocresol being considered as a “gold standard” has shown high success rates (ranging between 70-97%) as compared to all other techniques, but concerns about cytotoxicity and potential mutagenicity have been reported. As a consequence alternative techniques have been evaluated. Ferric sulphate (15.5%) has been used recently, and has gained much attention as a pulpotomy medicament. Aim: To compare the efficacy of formocresol and ferric sulphate Pulpotomies, in cariously exposed primary molar teeth in age group 5-10-years in Dental Department, Children hospital, PIMS, Islamabad, which is affiliated with QPGMC. Materials and Methods: 70 healthy subjects between the age group of 5-10 years with cariously exposed vital pulp were randomly allocated to either the formocresol or the ferric sulphate group of 35 teeth each. The pulpotomy procedure was performed on the selected teeth. The patients were recalled after 3 and 6 months interval and were evaluated both radiographically and clinically. The data was analyzed using the SPSS statistical software programme version 14. Total duration of this study was nine months from Jan 2009- September 2009. Results: Amongst the subjects, 61.4% were males and 38.6% were females. The teeth most commonly involved were the mandibular second primary molars. At 6 months follow up, only 2 out of 35 patients in both FC and FS groups reported pain and showed periapical radiolucency, thus the success rate in both FC and FS group was found to be 94.28%.
Conclusion: There were no statistically significant differences between the success rates for the two groups at the P < 0.05 level as tested by Fisher’s exact test. This study shows that Ferric Sulphate appears to be a promising alternative material for pulpotomy in primary molar teeth.
