ANTIBIOFILM ACTION OF DIFFERENT TREATMENTS FOR DECONTAMINATION OF LATEX AND SILICONE PACIFIERS

Purpose: the aim of this study was to evaluate the in vitro efficacy of three differents decontaminating treatments on oral bacterial biofilms developed on the surface of pacifiers made with silicone or latex. Methods: on the surfaces of 96 pacifiers made of silicone and latex of two comercial brands, biofilms were developed from the following reference strains (ATCC): Streptococcus mutans (25175) and Lactobacillus casei (11578). The pacifiers were then divided into 4 groups (N=12) according to the treatments: control group (without treatment), boiling water (1 minute), microwave (7 minutes), and chlorhexidine digluconate solution at 0.12 % (spray 6 times, 0.6 mL). The data were submitted to one-way ANOVA for repeated measures. The significance level established was of 5%. Results: at the moment, the data are under statistical treatment and will be available for presentation at the event. Conclusions: the conclusions will be formulated from the results of the statistical analysis.
