Abstract:
Mineral Trioxide Aggregate (MTA) has been used in many endodontic procedures with success. We hypothesized that MTA as a pulpotomy medicament elicits outcomes no different than that of the diluted formocresol (DFC).
Purpose:
The purpose of this study was to compare the outcomes of grey MTA and DFC in primary molar pulpotomies at a teaching institution and a pediatric dental practice.
Methods:
At the teaching institution, 206 primary molars of 122 children were enrolled. At 48-months, 20 teeth treated with MTA and 25 teeth treated with DFC, were available for evaluation. At the private practice, dental records of 245 primary molars of 68 patients were available for evaluation.
Results:
At 48 months, the results from both sites showed a radiographic success rate of 80 percent for DFC and 95 percent for MTA. The odds of radiographic failure were not affected by study sites. The Cox-regression analysis revealed that patient's age at the time of pulpotomy impacted the "hazard of exfoliation." Each year following the completion of DFC or MTA pulpotomy, there is a 4.6-times-more-likely chance for early exfoliation of the pulpotomized tooth.
Conclusion:
Grey MTA is an acceptable alternative for primary molar pulpotomies.
