Histologycal Assessment of Pulp Response and It’s Morphological Changes under the Influence of Mta as Capping Agent, Studied on Light Microscope

Multiple analyses discussed using MTA as direct capping material. These reports have shown that MTA is a promising material for the preservation of pulp tissue when used as a direct capping material. Many clinical studies have demonstrated successful outcomes after the use of MTA as a capping agent on mechanically or cariously exposed pulps. The studies performed by us in this research focused primarily on highlighting the changes happening at a cellular level in dental pulp obtain from human teeth whose caries had been treated with MTA (Mineral Trioxide Aggregate), as compared to pulp originating from healthy teeth. For the investigations there have been used teeth that had been extracted for orthodontic purposes 6, 14 and 30 days after treatment of caries with MTA, as well as a healthy premolar extracted for the same purposes, which served as a benchmark. It seems that MTA is the ideal material for direct capping in permanent teeth, compared to currently used materials, it being a bioactive material that has the ability to create an ideal environment for healing. Our study confirms some of the studies made on MTA, meanwhile it does not confirm other studies. In conclusion our study confirms the presence and the forming of collagen matrix in the predentine area. This matrix is getting mineralized in time, forming osteodentine, followed by a tertiary dentine bridge, a few months after capping with MTA. Inflamatory phaenomens are persisting even after 2 weeks since capping, with a constant withdraw in the next period of time. The pulp-dentine plate apears formed 30 days after capping.
