Secondary caries is related to the colonization of the tooth restoration interface by cariogenic microorganism. Believed that the use of materials with potential antimicrobial activity, either as protection of the dentin-pulp complex or as restoration, may have a role in preventing secondary caries. To verify this, we analyzed the following materials: acrylic resin; glass-ionomer, Maxxion-R; tooth sealant, Ultra Seal XT-Ultradent; fluid resin, Perma Flo – Ultradent; ionomer sealant, Clinpro XT Varnish – 3M; and adhesive system, PQ1 – Ultradent. The agar diffusion test performed to determine the bacterial growth inhibition of Streptococcus mutans. The materials were prepared according to the manufacture's recommendations under aseptic conditions, and placed in Petri dishes containing solid BHI medium with 0.2 U/L bacitracin (selective medium for S. mutans), prepared in triplicate. The plates incubated at 37°C with 5% CO2 and observed daily for 7 days. The antimicrobial activity of these materials obtained by the ratio between the diameter of the specimen and the diameter of the halo of growth inhibition formed around it. As expected, the acrylic resin (negative control) showed no antimicrobial activity, while the glass-ionomer (positive control) showed inhibitory activity. Between the tested materials, only the ionomer sealant and adhesive system showed significant antimicrobial activity, compared to controls. [ABSTRACT FROM AUTHOR] |
