one-year outcomes of mta and modified portland cement pulpotomy in primary teeth: a randomized clinical trial

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.
