Study Title:

Grape seed extract: An innovation in remineralization.

Study Abstract

AIM:
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).

SUBJECTS AND METHODS:
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.

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

RESULTS:
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).

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