Treatment Outcome of Mineral Trioxide Aggregate or Calcium Hydroxide Direct Pulp Capping: Long-term Results

Direct pulp-capping is a treatment for exposed vital pulp involving the placement of a dental material over the exposed area. This facilitates both the formation of protective barrier and the maintenance of vital pulp. Direct pulp capping (DPC) has been used as an alternative approach to the maintenance of vital pulp. So, many tooth extractions and root canal treatments could have been avoided through the conservative approach of direct pulp capping. For this purpose, different kinds of materials used such as Zinc Oxide Eugenol, Glass Ionomer (GI), Resin Modified Glass Ionomer (RMGI), Adhesive systems, Calcium Hydroxide (CH), Mineral Trioxide Aggregate (MTA) and Bio dentine. MTA performed more effective than conventional Calcium Hydroxide clinically as a direct pulp capping material. MTA showed higher success rate than dycal. MTA is easier to use clinically as a direct pulp capping material. MTA also provided better long-term results and more effective than Calcium Hydroxide in maintaining long-term vitality. MAT is significantly less toxic, less pulpal inflammations. Furthermore, MTA is more predictable than dycal in formation of dentin barrier and superior than Calcium Hydroxide in dentinogenetic process in human pulp. MTA is more effective and superior comparing the Calcium Hydroxide as a direct pulp capping material, demonstrating higher success rate with favorable outcomes in maintaining long term tooth vitality and easier to use in pulp capping. Finally, MTA is more cost-effective than CH for DPC despite higher initial treatment costs because expensive retreatments were avoided.

The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 ?C. Mineral trioxide aggregate, bioactive dentin substitute or calcium-hydroxide paste were used as pulp capping materials. Cavities were restored with a light-cured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calcium-hydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5?C.
