Abstract
This in vitro experimental study on 24 extracted sound human maxillary central incisors was conducted to evaluate the effects of two Recaldent® products and artificial saliva on the hardness of enamel. All hardness measurements were taken with Vickers hardness tester.A two stage blinding procedure was performed. Data was entered into MS Excel spreadsheet and processed using SPSS software version 15.0. One way analysis of variance (ANOVA), Student t test and Bonferroni test were performed.
The difference in enamel microhardness between baseline and demineralization in the groups A1, A2, A3 were 1.1, 0.4, 1.1 respectively. The mean difference in enamel microhardness measured afterremineralisationin the groups A1, A2, A3 were 3.8, 2.9, 0respectively.
CPP-ACP and CPP-ACFP increase the microhardness of enamel. Artificial saliva increases the hardness of enamel, but to a lesser extent than CPP-ACP and CPP-ACFP. There is no difference between the remineralising capacity of CPP-ACP and CPP-ACFP.
