Study Title:

Grape seed extract: An innovation in remineralization.

Study Abstract

The aim of this study was to determine remineralizing potential of grape seed extract (GSE) compared to casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and calcium glycerophosphate (CaGP) through pH-cycling model and subsequent evaluation using polarized light microscope (PLM).

Twenty sound human teeth fragments of ten teeth were obtained from the cervical portion of the roots and were stored in demineralizing solution for 96 h at 37°C to induce artificial root carious lesion. The sections then were divided into four treatment groups including: 6.5% GSE, CPP-ACP, 0.5% CaGP, and control group (no treatment). The demineralized samples were then pH cycled through treatment solutions, acidic buffer, and neutral buffer for 8 days at six cycles per day. The samples were subsequently evaluated using PLM.

Data were analyzed using ANOVA and Scheffe post hoc comparison test (P < 0.001).

PLM data revealed a significantly thicker mineral precipitation band on the surface layer of the GSE-treated lesions compared to the other groups (P < 0.001).

GSE positively affects the demineralization and/or remineralization processes of artificial root caries lesions.
