Abstract
Purpose: The aim of this present study was to observe clinical, radiographic response of pulp to Ferric Sulphate and Mineral Trioxide Aggregate when used as pulpotomy agent in primary molars.
 Materials and Methods: Sixty restorable primary molars were selected for the study. The children were chosen who require minimum two pulpotomies in either arch preferably each on the opposite side (i.e. right and left). Primary molars on the right side of the patient were assigned to Ferric Sulphate (FS) (Group A) and left side was assigned for the Mineral Trioxide Aggregate (MTA) (Group B). Statistical analysis was done for pain, swelling, sinus, and fistula and for internal resorption, furcation radiolucency and periapical pathology using the chi-square test.
 Results: outcome of the present study was observed at 3 month interval and after 6 months. The clinical success rate for MTA (AQUA) and ferric sulphate during 3 and 6 month follow up was 100%. The radiographic follow up of MTA was 100% during 3 and 6 month, whereas it was 96.6% for 3 and 6 month follow up with respect to ferric sulphate. There were no significant differences in the clinical (p>0.1) and radiographic (p>0.98) success rates among both the groups.
 Conclusion: ferric sulphate was found to be equally effective when compared with MTA. Radiographic success rate was lower for Ferric sulphate (Group A) than that of MTA (Group B) with occurrence of one internal resorption seen with first primary molar.
Highlights
There have been many advances in the prevention of dental caries thereby understanding the importance of preserving natural teeth has increased [1]
Total 60 mandibular primary molars in 30 children were selected for the study. 60 teeth were distributed between group A (30 teeth) and Group B (30 teeth)
Primary molars on the right side of the patient were assigned to Ferric Sulphate (FS) (Group A) and on the left side for the Mineral Trioxide Aggregate (MTA) (Group B)
Summary
There have been many advances in the prevention of dental caries thereby understanding the importance of preserving natural teeth has increased [1]. Pulpotomy in primary dentition is the most common endodontic treatment for inflammation of coronal pulp caused by caries or trauma. The rationale for pulpotomy of primary teeth is based on the assumption that inflammation is limited to coronal portion of dental pulp and that the radicular pulp has the potential to heal [4]. Most primary molars with proximal caries have inflammation in pulp horns, even in small lesion extending less than half intercuspal distance, and manifesting well before clinical exposure [5]. The operator relies on subjective criteria to determine whether the remaining pulp is affected or not such as bleeding time of the radicular pulp stump after amputation, color of hemorrhage and consistency of the tissue [4]
