Antimicrobial power of composite resin adhesion systems.
The adherence of microorganisms to dentin that had been contaminated and then treated with conditioning substances was evaluated. The germicide effect of those products and their possible substantivity was also evaluated. Dentin slices were contaminated with Candida albicans, Streptococcus mutans and Actinomyces naeslundii and then treated with the following substances: 1. Experimental Blue Solution A, 2. Experimental Red Solution B; 3 Tubulicid Blue Label; 4. Tubulicid Red Label; 5 Scotchprep Dentin Primer; 6 ventura Dentin Bond Cleaner; 7 ventura Dentin Bond Primer, 8. Gluma dentin Bond; 9 Tenure Conditioner; 10. All Bond Dentin Conditioner; 11 Syntac Primer; 12. Clearfil New Bond acid + adhesive; 13 Prisma Universal Bond 3 Primer; 14. Denthesive Cleaner; 15. Control (Distilled water). Adherence was evaluated using scanning electron microscopy and viability tests were performed. Substances 1, 2, 3, 4, 5, 7, 8, and 11 impair adherence; the control and substances 6 and 9 produced no afforded intermediate results effect while substances 10, 12, 13 and 14. Viability tests afforded results similar to those obtained for adherence. Several substances that are used for dentin treatment or for dentin priming for adhesion could be useful in preventing microorganism viability and so contribute to the protection of pulp vitality.
