remineralizing effect of child formula dentifrices on artificial enamel caries using a ph cycling model.

although fluoridated toothpastes are among the most accessible fluoride sources for caries prevention, their remineralization potential remains questionable. this study sought to compare the effects of 5 different child formula dentifrices on remineralization of artificial primary enamel caries using a ph cycling model.twenty sound primary canine teeth were immersed in demineralizing solution for 96 hours to produce 100μm-deep artificial caries. the teeth were then longitudinally sectioned into 100-150 μm-thick slices and randomly divided into 5 groups and treated as follows: group a. calcium phosphate toothpaste, group b. pooneh children's toothpaste, group c. biotin toothpaste, group d. crest children's toothpaste and group e. darougar children's toothpaste. the specimens underwent a ph cycling model for 10 days. the degree of demineralization before and after treatment and its changes were evaluated under a polarized light microscope and a stereomicroscope and data were statistically analyzed using repeated measures anova and post-hoc test.stereomicroscopic analysis showed that only group c had a significant difference with other groups (p 0.05). polarized light microscopic analysis revealed that in addition to group c, a significant difference was detected between groups a and b (p=0.02) and calcium phosphate toothpaste showed higher efficacy.all the understudy toothpastes had remineralizing effect but calcium phosphate children's toothpaste had the highest and biotin toothpaste had the lowest efficacy.
