Abstract:
Objective
To evaluate the clinical effect of iROOT BP Plus in pulpotomy for primary molars with deep caries.
Methods
A total of 60 children with deep caries in primary molars were chosen, who received treatment in Shenyang Sixth People's Hospital from March 2017 to March 2018, and they were randomly divided into 3 groups based on the pulp-capping agent: iRooT BP Plus group, MTA group and VITAPEX group,20 cases in each group. The three agents were respectively used in pulpotomy. The operation time and the success rate at 3,6 and 12 months after operation were compared among the 3 groups.
Results
The operation time of group VITAPEX was the shortest, and the operation time of group MTA was the longest, there being significant difference among the three groups（P＜0.05）. Twelve months after treatment, there was one lost case respectively in iROOT BP Plus group and MTA group; there was no significant difference in success rate between iROOT BP Plus group and MTA group（P＞0.017）,but the success rate of iROOT BP Plus group and MTA group was significantly higher than that of VITAPEX group（P≤0.017）.
Conclusion
The short-term clinical effect of iROOT BP Plus in pulpotomy for primary molars with deep caries is similar to that of MTA. It has a broader prospect in the application of pulp preservation.
