Abstract
Vital pulp treatment in primary molars has a fundamental role in pediatric dentistry preserving tooth function and dental arch integrity. Although MTA has been recently considered the “gold standard” material for pulpotomy procedures, some drawbacks such as poor handling and long setting time are challenging when used as a pulpotomy dressing in the primary teeth of a child. Thus, the evaluation of the clinical and radiographic performance of other bioactive materials such as a premixed bioceramic root repair material with faster setting time is of paramount importance for the management of dental caries in the pediatric patient.
The aim of the presented randomized controlled trial (RCT)was primarily to evaluate the efficacy of a bioceramic root repair material as pulp dressing in pulpotomy of primary molars. The clinical and radiographic success of this material was compared to MTA, with or without the added peripheral seal of a SSC. Secondly, handling properties as well as patient perceived pain of both pulp capping materials were compared.
In this double blinded RCT, 64 primary molar teeth eligible for vital pulpotomy were included. After hemostasis was achieved with a wet cotton pellet, the molars were randomly allocated to one of the four treatment groups, namely MTA+SSC, MTA+GI, BC RRM+GI and BC RRM+SCC.
All teeth were evaluated clinically and radiographically by a single blinded examiner according to the modified Zurn and Seale criteria at 1, 3, 6, and 12 months follow up. Time required to perform the pulp capping procedure was measured in minutes. Comparing handling properties was done by asking experts in the field to rate both pulp capping materials regarding ease of handling and convenience of application. Self-reported patient perceived pain was done using the Wong-Baker FACES® Pain Rating Scale in Arabic.
The following is a summary of the main results:
1. There was no significant difference between the efficacy of TotalFill® BC RRM™ Fast Set Putty and PDTM MTA WHITE as pulp capping materials in primary molar pulpotomy.
2. Among the groups studied, the highest overall success rate after 12 months was for MTA+SSC followed by BC RRM+SSC, then MTA+GI and lastly BC RRM+GI.
3. Clinical success at 12 months was 93.8% for MTA+SSC, 87.5% for both MTA+GI and BC RRM+SSC, and 81.2% for BC RRM+GI. Radiographic success at 12 months was 81.2% for both SSC groups, followed by MTA+GI and BC RRM+GI groups at 62.5% and 56.2%, respectively.
4. There was a significant higher clinical and radiographic survival of pulpotomized primary molars restored with SSC compared to GC EQUIA Forte® HT regardless of the pulp capping material used.
5. According to experts’ opinion, there was no statistically significant difference between the handling properties of TotalFill® BC RRM™ Fast Set Putty and PDTM MTA WHITE as pulp capping materials in primary molar pulpotomy, except for setting time.
6. There was no statistically significant difference in time required to place the pulp capping materials TotalFill® BC RRM™ Fast Set Putty and PDTM MTA WHITE on the amputated pulp stumps of primary molars.
7. There was no statistically significant difference between pulpotomy procedures using PDTM MTA WHITE or BC RRM™ Fast Set Putty as pulp capping materials and between SSC or GC EQUIA Forte® HT in children’s self-reported post-procedural pain.
