Evaluation of anti-bacterial effect of bifluorid 10 and Mi paste dentin desensitizer on cariogenic bacteria Streptococcus mutans, Streptococcus sobrinus and Lactobacillus acidophilus

Dental caries is an infections disease leading as dynmic process with attack (demineralization and compensation (remineralization) of dental material.The aim of this study to evaluate the antibacterial effect of two dentin desensitizers, Vocco Bifluoride 10 and MI paste, on the cariogenic bacteria Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus.

In this experimental laboratory study, samples of Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus were used. From each of the compounds of Bifluoride 10 and MI paste 3 discs and 6 culture media for each bacterium were prepared. After drying and sterilizing the disks, the quality control operations of the disks were performed and cultured in culture media at 37 ° C for 48 hour. According to the antimicrobial halo around each disk, its measurement the growth or non-growth of bacteria was examined. Data were analyzed using t-test and two-way ANOVA

In inhibition of streptococcus mutans, Biflooride 10 was more effective, significant. (P=0.029) and in line with streptococcus sabrinus, poste ml was more effective (P=0.003).

The use of Bifluoride and MI paste is effective on diameter of the non-growth halo of cariogenic bacteria Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus and therefore but MI paste had more effect in elimination of carigenic bacteria.
