Background Although child formula fluoridated dentifrices can be used safely by young children their remineralizing capability remains questionable. Aim To evaluate the remineralizing potential of child formula dentifrices on primary teeth. Design In vitro single‐section technique utilizing a 7 days pH‐cycling model. Methods Primary teeth were placed in demineralizing solution for 96 h to produce artificial carious lesions 100 μm deep, and then cut longitudinally into 50 sections 100–150 μm thick and randomly assigned to five groups. Sections in Groups A to D were treated with dentifrices containing 500 ppm AmF, 500 ppm MFP, 500 ppm MFP and xylitol, or 500 ppm NaF, respectively. Group E sections were treated with a nonfluoridated dentifrice. Outcome measurements Lesions were evaluated using polarized light microscopy and microradiography. Results Group D (500 ppm NaF) sections exhibited a significant decrease in lesion depth, whereas those in Group E (nonF) showed a significant increase in depth ( P < 0.05, paired t ‐test). Decrease in lesion progression was observed in Groups A, B and C. Conclusions The 500 ppm NaF dentifrice demonstrated remineralization of carious lesions by virtue of a significant decrease in lesion depth; whereas dentifrices that contained AmF, MFP and MFP with xylitol decelerated the progression of demineralization.
