RESUMO
Using fluoride mouthrinses is one of the most effective ways for prevention of dental caries. For obtaining this benefit, the ministry of health has started using sodium fluoride mouthrinse in primary school children. The aim of this study was evaluation and comparison of salivary fluoride after using Kimia and Share Daroo mouthrinse. In this experimental study, 42 physically and dentally healthy children, used 10 ml of 0.2% sodium fluoride mouthrinse for 1 minute and then expectorated it. Unstimulated whole saliva [in five minute intervals] was taken in baseline, and after 5, 15, 25 and 45 minutes. 7 days after taking the first test, the second test was taken by using the second mouthrinse. After the collection of all of samples, the content of fluoride and volume of samples was determined and the results were statistically analyzed by using the 2-way repeated measure ANOVA. Fluoride concentration of saliva after using Kimia mouthrinse was 0.95 +/- 0.17 and 0.198 +/- 0.18 after using Shahre Darou mouthrinse. Fluoride concentrations of saliva after using mouthrinse, was not statistically significant between the gender and the two ages. Results of this study showed that no statistically significant differences of fluoride retention in children's saliva exist between the two Iranian 0.2% sodium fluoride mouthrinses
