One-year outcomes of MTA and modified Portland cement pulpotomy in primary teeth: a randomized clinical trial

Abstract

Purpose: To compare the efficacy of Mineral Trioxide Aggregate (MTA) and Modified Portland Cement (MPC) as pulpotomy medicaments in primary molars. Methods: A sample of 54 children 4 to 6 years old of age, who had at least one primary mandibular second molar that needed pulpotomy were randomly placed in MTA (n = 28) or MPC (n = 26) groups. After completing the pulpotomy procedures, the teeth received a stainless-steel crown. Clinical and radiographic successes/failures were blindly evaluated at 6 and 12 months, and Fisher's exact test was used to analyze the differences. Results: At 6- and 12-month follow-ups, MTA and MPC had 100% clinical success rate. Radiographic success rates of MTA were 92.9% at 6 months and 89.3% at 12 months. While the rate for MPC group was 88.5% at both intervals. There was no statistically significant difference between the two groups. Conclusion: The results of this investigation showed that treatment success rate with MPC was comparable to MTA pulpotomy. However, additional clinical research that considers long-term follow-ups is required to test the usefulness of MPC in the pulpotomy treatment of primary teeth.
