Gluconato de Clorhexidina al 0.12% en la inhibición de la adherencia del Streptococcus mutans en restauraciones provisionales de polimetilmetacrilato de metilo in vitro GHX como inhibidor de adherencias de microorganismos en provisionales

Abstract

Objective: The purpose of the present study was to evaluate in vitro the effect of Chlorhexidine gluconate at 0.12% in the adherence inhibition of Streptococcus mutans with provisional restorative at different exposure times (8, 16, 24, 32, 40, 48 hours). Material and methods: The study was of experimental type, for comparison groups. Total of 120 samples of Autopolymerizing PMMA divided in six groups were used (experimental and control groups). Results: No significant differences were found in medias of the first four groups (p > 0.05). The others showed significant difference between the experimental and control subgroups. Conclusion: The results demonstrated that the adherence of Streptococcus mutans to Autopolymerizing PMMA in vitro is inhibited after several applications of Chlorhexidine gluconate at 0.12%.
