Abstract
To evaluate remineralising effects of three dentifrices, Vicco by Vicco Labs, India, Perioe Cavity Care by LG Care, Korea and Colgate Total by Colgate-Palmolive, Thailand on artificial caries like lesions. In vitro single-section and pH cycling model. Extracted third molars were painted with nail varnish, leaving 1 mm wide windows before placing demineralising solution for 96h to produce artificial carious lesions 150-200 miocrom deep. Teeth were then cut longitudinally into 100-150 microm thick sections and randomly assigned to three groups. Polarised light microscopy and microradiography were used to evaluate lesion depth, before and after the 10 day pH cycle. Sections in Group A were treated with Vicco by Vicco Labs, India (-ve control), Group B were treated with Perioe Cavity Care by LG Care, Korea and Group C were treated with Colgate Total by Colgate-Palmolive, Thailand. Mean lesion depths in Groups B and C reduced by 7% and 12% respectively, whereas lesion depth increased by 13% in Group A. Comparisons made among groups using ANOVA and Student-Newman-Keuls tests showed that three groups were significantly different from each other (p < 0.05). Perioe Cavity Care and Colgate Total remineralised initial carious lesions. However, the remineralising potential of Colgate Total was higher than that of Perioe Cavity Care.
