Early responses of human pulp to direct capping with resin adhesive systems and calcium hydroxide

This study evaluated the biocompatibility of mineral trioxide aggregate (MTA) after direct capping of exposed pulp tissue in dog's teeth. Class I cavities were prepared in 26 teeth from 3 adult dogs. MTA was applied over the exposed pulp in 13 teeth and paste of calcium hydroxide plus distilled water (control) was applied in the remaining 13 teeth. After 90 days, the animals were killed; the maxilla and mandible were dissected and sectioned to obtain individual roots. The samples were processed histologically. The pulp and periapical response observed with the use of MTA was similar to that of calcium hydroxide paste. In all specimens, there was a dentin bridge obliterating the exposure, an intact odontoblastic layer, no inflammatory cells, normal connective pulp tissue, normal apical and periapical regions and no bone tissue changes. Similar to calcium hydroxide, MTA presented excellent response when used for direct pulp capping.

Objective: The aim of the present work was to morphometrically evaluate collagen in carious lesions sealed with calcium hydroxide, adhesive systems, glass ionomer cement, and an antibacterial cement. Study design: Samples of infected and affected dentin were stained with Sirius Red (SR). The areas intensively stained with SR were delimited, and the percentage of these areas was measured by blind calibrated examiners. The mean results were subjected to the Kruskal-Wallis test. Results: The affected dentin sealed with Ca(OH)2 showed a better organization of the collagen in relation to the adhesive systems Prime & Bond (p= .0159) and Adhese (p<0.0001). The affected dentin sealed with Prime & Bond promoted better increase of organized collagen areas in relation to Adhese (p = 0.0004). The infected dentin sealed with glass ionomer cement (p = 0.0018) or antibacterial cement (p = 0.0004) brought a significant increase in the organized collagen areas. Conclusions: Ca(OH)2 is indicated to seal affected dentin and glass ionomer cement and antibacterial cement may be used for treatment of infected dentin. The addition of antibiotics did not influence the restoration of the infected dentin.
