Summary
An auto-cured sealant resin showed promising results for direct pulp capping, though a self-etching primer improved outcomes. This study evaluates its efficacy in promoting dentin bridge formation and minimizing inflammation for dental pulp repair.
Area of Science:
- Dental materials science
- Restorative dentistry
- Biomaterials
Background:
- Direct pulp capping is a vital clinical procedure for preserving pulp vitality.
- Evaluating new biomaterials for pulp capping is crucial for improving treatment outcomes.
- Auto-cured resins offer potential advantages in direct pulp capping applications.
Purpose of the Study:
- To assess the efficacy of an auto-cured resin as a direct pulp capping agent.
- To investigate the influence of a self-etching primer on the performance of the auto-cured resin.
- To compare the outcomes with a commercially available adhesive resin system.
Main Methods:
- Class V cavities were prepared on monkey teeth with intentional pulp exposures.
- Exposed pulps were capped with an auto-cured resin (Teethmate-S) with or without a self-etching primer, or an adhesive resin system (Clearfil Liner Bond 2V).
- Histological evaluation of inflammatory cell infiltration, dentin bridge formation, and pulp tissue protrusion was performed at 3, 30, and 90 days.
Main Results:
- Dentin bridge formation and occlusion of exposed pulp areas increased over time.
- The auto-cured resin group without a primer (Group TM) showed significantly higher inflammatory cell infiltration at 30 days compared to the adhesive resin group (Group LB).
- Group TM also exhibited a significantly higher incidence of pulp tissue protrusion throughout the study period compared to Groups LB and TMP.
Conclusions:
- The auto-cured sealant resin (Teethmate-S) can facilitate dentin bridge formation in direct pulp capping.
- The use of a self-etching primer with the auto-cured resin may improve its biocompatibility and reduce inflammatory responses.
- Further research is warranted to optimize the application of auto-cured resins for direct pulp capping procedures.
