Abstract
© 2015, SEAMEO TROPMED Network. All rights reserved. The purpose of the present study was to evaluate the effect of fluoride mouthrinse containing tricalcium phosphate on microhardness of demineralized primary enamel. Thirty-six sound primary incisors were immersed in a demineralizing solution (pH 4.4) for 96 hours at 37°C to create artificial caries-like lesions. After artificial caries formation, the specimens were randomly divided into 3 groups (with 12 specimens in each group): Group A: deionized water; Group B: 0.05% NaF plus 20 ppm tricalcium phosphate mouthrinse and Group C: 0.05% NaF mouthrinse. All the specimens were immersed for 1 minute at 37°C three times per day for 7 days in the respective mouthrinse among pH cycling. The surface microhardness was examined using a Vickers hardness tester (100 grams for 15 seconds) at baseline, before and after the pH-cycling procedure. Data were analyzed using one-way ANOVA and Tukey’s multiple comparison tests with a significance level of 0.05. After treatment, Group A had a significantly lower surface microhardness value than the other two groups (p=0.000); however, there was no significant difference between Groups B and C (p=0.728). We concluded fluoride mouthrinse containing tricalcium phosphate and fluoride mouthrinse have similar remineralizing effects on microhardness of demineralized primary teeth.
