Objective: To observe the fluoride foam and chlorhexidine mouthwash for Streptococcus mutans in dental plaque and explore different time period changes in the number of bacteria , seek better caries prevention materials to provide experimental evidence for the clinical . Methods : 80 and 12 -year-old children are divided into A, B two groups according to the the DMFT different divided into groups of caries-free and caries group , two groups divided the standard is : DMFT = 0 are caries-free group , DMFT> 0 case of caries set of . A group to use 1.23% fluoride foam were measured before the intervention , 1h , 24h and 1 week plaque Streptococcus mutans ; Group B with 0.2% chlorhexidine mouthwash , measured before the intervention and 1 week of bacteria plaque Streptococcus mutans . Acquisition inoculated in MSA medium right maxillary first molar buccal plaque morphological and biochemical identification of bacterial culture and colony counting , and Streptococcus mutans . The SPSS univariate analysis of variance and t-test , P <0.05 was considered statistically significant . Results : 1 number of Streptococcus mutans in dental plaque fluoride foam 1h , 24h and weeks before the intervention level ( P <0.05 ) were significantly lower than : the use of chlorhexidine gargle mouthwash 1 week Streptococcus mutans is also significantly lower than the level before the intervention . Number of Streptococcus mutans detected in 3.1 weeks in group B caries-free group and caries group decreased by 57.94% and 52.91% , a decrease of 31.86% and 33.77 % in group A and B group declined significantly greater than the proportion of group A . Conclusion: fluoride foam and chlorhexidine mouthwash can significantly inhibit the number of Streptococcus mutans in dental plaque of children , but the chlorhexidine group bacteriostatic effect is relatively stronger than fluoride foam group , both of which are as a children's caries disease prevention methods .
