Partial pulpotomy success in primary molars followed up for 24 months: A randomized controlled clinical trial using mineral trioxide aggregate, biodentine, and acemannan

Abstract

AbstractBackgroundFinding the best treatment approach and suitable capping materials in primary molars with deep carious lesions remains unresolved.AimTo compare the success rates of partial pulpotomy in deep caries lesions in primary molars treated with mineral trioxide aggregate (MTA), biodentine, or acemannan for 6–24 months.DesignA parallel‐design, non‐inferiority randomized controlled clinical trial was performed. Ninety mandibular primary molars from 65 children meeting the criteria, aged 3–8 years, were included. After inflamed pulp tissue removal and hemostasis, each tooth was randomly allocated into the MTA control group, or the biodentine or acemannan experimental group (N = 30 per group). All teeth were restored with a stainless steel crown. The outcomes were evaluated for 6–24 months. A generalized estimating equation model was used to compare the overall success rate in each group.ResultsAfter 24 months, 58 children (83 teeth) were available for evaluation. The results indicated that the success rate in the MTA, biodentine, and acemannan groups was 83.3%, 76.9%, and 74.1%, respectively. No significant difference in success rates among groups, however, was observed at the 6‐ to 24‐month follow‐ups (at 24th month, p = .30).ConclusionThere was no statistically significant difference between MTA, biodentine, or acemannan in the partial pulpotomy success after 24 months.
