Despite the high prevalence of tooth-caries and various efforts to prevent it, studies on plant compounds and their anti-caries properties have been largely neglected. Brushing with toothpaste is the most effective way for caries prevention. This study was performed on KREND herbal toothpaste (containing Calendula and Salvia Officinalis), Herbex (containing propolis), and Crest herbal toothpaste. The remineralization effect of these toothpaste brands on carious lesions has not been studied yet. Therefore, we compared the remineralizing effect of Iranian toothpaste and foreign types in this study. Method and materials: 60 caries-free human premolar teeth were collected after extraction for orthodontic purposes. The surface microhardness (SMH) was measured using the Vickers microhardness testing machine at baseline and after four days of immersing in demineralization solution and after treatment. The pH cycle was then performed for 28 days. The teeth were allocated randomly into one of the four groups, group 1 (as the control group and immersed in distilled water), group 2 (treated with KREND herbal solution), group 3 (treated with Crest solution), and group 4 (treated with Herbex solution). Finally, data were analyzed with Repeated Measure ANOVA and SPSS version 18. All study groups’ surface micro-hardness measures were decreased after demineralization (P=0.001) and were increased after pH cycling (P<0.001). There wasn’t a statistically significant difference in mean Surface micro-hardness changes between study groups (P=0.433). This study showed that the remineralization ratio in study group samples increased after treatment with herbal toothpaste, and the Iranian toothpaste (Krend) and foreign ones had a similar remineralizing effect.
