Abstract
BACKGROUND/AIM: A new bioceramic material iRoot BP Plus has been introduced and reported to have good biocompatibility, sealing ability and antibacterial activity. It has also been reported to be successfully used for procedures such as pulpotomy, pulp floor perforation repair and so on. However, there are only a few reports on the use of iRoot BP Plus in the management of traumatised teeth with an exposed pulp. The aim of this study was to investigate the clinical and radiographic outcomes of partial pulpotomy with iRoot BP Plus in immature permanent teeth with complicated crown fracture or complicated crown-root fracture. MATERIAL AND METHODS: The study was prospectively designed and 110 immature permanent teeth with complicated crown fracture or complicated crown-root fracture were randomly allocated into two groups (n = 55). All teeth were clinically and radiographically assessed at 1, 3, 6, 12, 18 and 24 months after partial pulpotomy with iRoot BP Plus (experimental group, n=50) or calcium hydroxide (control group,n=49) as the pulp capping agent. Eleven cases were lost during follow-up, and 99 teeth were finally analysed. RESULTS: There were no intergroup differences in the survival rate, survival time, root length and dentin wall thickness. The calcific bridge was significantly thinner in the iRoot BP Plus group than in the calcium hydroxide group (0.97±0.13mm vs. 1.36±0.12mm; F=5.128, P=0.029). CONCLUSIONS:iRoot BP Plus may be an effective capping material for partial pulpotomy. This article is protected by copyright. All rights reserved.
