Abstract
X. Summary
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 pulp dressing material in the primary molars of a child. Thus, the evaluation of the clinical and radiographic performance of other bioactive materials such as a BiodentineTM 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 clinical and radiographic success of Mineral Trioxide Aggregate and Biodentine in direct pulp capping, partial pulpotomy, and pulpotomy in primary molars. Secondly, time needed for each procedure as well as patient cost effectiveness of each procedure.
In this clinical trial, 150 primary molars eligible for vital pulp therapy were included. After hemostasis was achieved with a wet cotton pellet, the molars were allocated to one of the six treatment subgroups (25 molars per subgroup), namely: MTA Direct Pulp Capping, MTA Partial Pulpotomy, MTA Pulpotomy, BiodentineTM Direct Pulp Capping, BiodentineTM Partial Pulpotomy, BiodentineTM Pulpotomy.
All teeth were evaluated clinically and radiographically by a two blinded investigators according to the modified Zurn and Seale criteria at 6, 12, and 18 months follow-up. Time required to perform each procedure was calculated in minutes and seconds. A patient satisfaction questionnaire was conducted after each procedure. Comparing cost effectiveness of each material was done.
The following is a summary of the main results:
1. There was no significant difference between the efficacy of NeoPUTTY MTA and BiodentineTM as pulp capping materials in primary molar pulpotomy.
2. Among the groups studied, the highest overall success rate after 18 months was for Pulpotomy with NeoPUTTY MTA (95.83%) followed by Pulpotomy with BiodentineTM (91.67%), then Direct pulp capping with both materials (87.5%, 83.3% respectively) and lastly Partial pulpotomy with the same two materials (70.8%, 66.6% respectively).
3. There was a statistically significant difference in time required to perform direct pulp capping when compared to partial pulpotomy and pulpotomy in primary molars (P< 0.001).
4. There was no significant difference between the two groups regarding the patient’s satisfaction after each procedure.
5. Regarding cost effectiveness of each procedure, direct pulp capping was the most cost effective followed by partial pulpotomy then pulpotomy procedure.
