Abstract
Objective The present study aimed to compare protective effects of CPP-ACP paste and fluoride gel on microhardness of enamel surface eroded by a cola drink and to compare effect of artificial saliva with CPP-ACP paste or fluoride gel on protective effect of microhardness of enamel surface eroded by a cola drink Materials and methods The specimens were prepared from 60 extracted human lower incisors, randomly divided into 6 groups; 1) CPP-ACP with deionized water 2) CPP-ACP paste with artificial saliva 3) artificial saliva 4) fluoride gel with deionized water 5) fluoride gel with artificial saliva and 6) deionized water. The microhardness of labial enamel surface of the six groups were measured by a Vickers microhardness tester with five indentations and interval of 120 μm. Surface microhardness readings were performed at baseline and after erosion by a cola drink. Data were analyzed by Paired-Sample T-Test, Two Way ANOVA and One Way ANOVA. Results After eroded by a cola drink, the enamel hardness significantly decreased in all groups studied. The hardness values of CPP-ACP paste with artificial saliva group and fluoride gel with artificial saliva group were higher than others significantly. Conclusion CPP-ACP paste and fluoride gel can not protect hardness of enamel after eroded by a cola drink, but CPP-ACP paste with artificial saliva and fluoride gel with artificial saliva can reduce the degree of demineralization.
