    Abstract:
    Dentin treatment before adhesion of composites is performed both to enhance adhesion and to remove the microbial contents of the smear layer. The purpose of these experiments was to evaluate the germicide potential of several dentin treatments used in adhesive systems and of some cleansing solutions. Different germs involved in caries processes were used (Candida Albicans, Streptococcus mutans and Actinomyces naeslundii) to prepare suspensions. Half a milliliter of each of the suspensions was transferred to test tubes and an equal volume of the following substances was added: Scotch Prep Dentin Primer (P), Gluma Cleanser (G), Cleaner Sol. (C), Tubulicid Blue (TB) and Red Label (TR), Blue Experimental Solution (SB) and Red Experimental Solution (SR) and sterile distilled water (control). The preparation was incubated at 37 degrees C for seven days to test viability. P, TR, TB and SB produced complete inhibition of germs tested. The results reveal that, "in vitro", not all the substances tested exert a germicide effect on the microorganisms analyzed.
