Abstract: This study was designed to evaluate clinical and radiographic success rates of Mineral Trioxide Aggregate (MTA) as a relatively new pulpotomy agent for pulp treatment of primary teeth. This prospective investigation was carried out on a group of children with a mean age of 6.4 years who were referred to Shiraz Dental School for routine care. Pulp amputation was carried out following routine local anesthetic induction on selected primary molars and then MTA (Pro root, USA) was placed over the already formed clot at the canal orifices. All teeth were restored using Stainless Steel Crowns and a recall program was set for 6, 12 and 24 months. Clinical and radiographic evaluations were attempted in all recall visits. Overall 55 primary molar teeth were treated by this new technique 4 of which failed for any follow-up evaluations. Apparently, all of the remaining 51 treated teeth were found to be sound and without any sign or symptoms both by clinical and radiographic means (100% success at 12 and 24 months), postoperatively. Based on the findings of this study, it seems that MTA could be used as an alternative to the current Formocresol medication with high clinical and radiographic success in pulpotomy of primary teeth.
