Abstract

The present study evaluated the ability of a high-fluoride dentifrice containing tricalcium phosphate to remineralize white spot lesions and inhibit lesion formation. Three demineralized enamel blocks and three healthy blocks (cut from a group of 30 molars), were exposed in pairs (one demineralized, one sound) via an appliance worn by 30 adults in a three-phase crossover study lasting 28 days per phase. The pairs were exposed to three dentifrices: one contained 5,000 ppm fluoride with tricalcium phosphate, one contained 5,000 ppm fluoride alone, and one contained no fluoride at all. Lesion status was analyzed using surface microhardness and transverse microradiography. Surface microhardness showed that the two dentifrices containing fluoride significantly inhibited enamel demineralization (p < 0.05) and significantly remineralized white spot lesions (p < 0.05), while the fluoride-free dentifrice did not. The results indicate that combining fluoride with tricalcium phosphate could provide more anti-caries benefits compared to using fluoride alone.
