Abstract

Resin-based Ca-PO₄ cements without (Cement A) and with a fluoride-releasing additive (Cement B) were used to treat caries-like lesions on enamel and dentin thin sections of human molars (Model I), which were then incubated for up to 6 weeks in distilled H₂O. Caries-like lesions on coronal dentin were coated with Cement B or a composite resin and incubated in saliva-like solution (Model II). The mineral loss (Δ}Z) was determined by digital analysis of microradiographs of the thin sections before and after treatment (Model I). In Model II thin sections were cut after the incubation and Δ}Z under Cement B was compared to Δ}Z under the composite resin. Exposure to Cement B resulted in greater remineralization of dentin lesions than Cement A. Incubation in saliva-like solution and/or the technique used in Model II had significantly higher remineralization than the treatment used in Model I.
