Aim: To evaluate the remineralizing potential of child formula dentifrices on primary teeth using an in vitro 7 days pH cycling model. Materials and Methods: Twenty-one primary teeth were placed in demineralizing solution for 96 h to produce artificial carious lesions; then cut longitudinally into 100-150 μm thick sections and randomly assigned to three groups. Sections in Group A were treated with dentifrice containing 458 ppm monofluorophosphate (MFP) and sections in Group B with 500 ppm sodium fluoride (NaF). Group C sections were treated with a nonfluoridated dentifrice. Results: Group A (458 ppm MFP) and Group B (500 ppm NaF) showed significant decrease in lesion depth, whereas Group C (non F) showed a significant increase in depth (P ≤ 0.05, paired t-test). Conclusion: Though dentifrices containing 458 ppm MFP and 500 ppm NaF demonstrated remineralization of carious lesions, it was not complete. Therefore, it is also important to emphasize on other preventive methods in the prevention and/or reversal of carious lesions.
