ABSTRACT Objective Remineralization is an effective treatment that may stop or reverse early tooth decay. Grape seed extract (GSE) is the potential remineralizing agent under investigation. Materials and methods Sound human tooth sections were obtained from the cervical portion of the root and stored in demineralizing solution at 37°C for 96 hours to induce artificial root caries lesions. The sections were divided into four treatment groups including 6.5% grape seed extract, sodium monofluorophosphate (220 ppm) with 0.05% calcium glycerophosphate, 0.5% calcium glycerophosphate and control (no treatment). An in vitro pH cycling model was used to cycle the demineralized specimens through treatment solutions, acidic buffer and neutral buffer for 8 days at 6 cycles per day. Subsequently, they were evaluated using confocal laser scanning microscope. Data were analyzed using analysis of variance (p < 0.05). Results GSE revealed less demineralization and more remineralization compared with other groups. Conclusion GSE promotes remineralization of artificial root caries lesions. Clinical significance The search for the perfect remineralizing agent continues to this day. GSE could be a welcome addition to the remineralization armamentarium.

ABSTRACTObjective: Grape seeds are gaining more importance because the “Proanthocyanidins” present in them have excellent anticaries, remineralizing, andantibacterial properties. Although many preventive measures have been tried, dental caries remains one of the most prevalent diseases in humans.The ultimate goal of any intervention is the preservation of tooth structure, prevention of lesion progression and inducing remineralization. Thepresent in-vitro study was done to investigate the effect of grape seed extract (GSE) on artificial enamel caries in human teeth.Methods: A total of 50 sound premolars extracted from patients undergoing orthodontic treatment were used in the study. The teeth were cleanedand were immersed in a demineralizing solution for 96 hrs at 37°C and 50% relative humidity to create artificial lesions. The samples were randomlydivided into two groups of 25 each. Half of the samples were immersed in the GSE solution (test) and the other half in saline (control), respectively, for8 days. The samples were measured by microhardness tester to obtain values in Vickers hardness scale. Data were entered into Microsoft Excel andwere analyzed using independent t-test for inter-group comparison and paired t-test for intra-group comparison using SPSS version 21.Results: The mean±SD microhardness values after remineralization for the test and control groups were 357.56±5.53 and 337.60±6.38. GSE groupsignificantly increased the microhardness of the lesions (p≤0.001).Conclusion: GSE is a potential remineralizing agent and can be used to prevent progression of dental caries.Keywords: Grape seed extract, Remineralization, Dental caries.

Grape seed extract (GSE) is a rich source of proanthocyanidins, a class of natural antioxidants reported to have wide-ranging bioactivity as anti-inflammatory, anticarcinogenic, and antimicrobial agents. The ability of GSE to rapidly inactivate Listeria monocytogenes in vitro and the generally recognized as safe status of GSE make this extract an attractive candidate for control of Listeria in or on foods. Previously, GSE has been used at relatively high concentrations (1%) in complex food matrices and in combination with other antimicrobials. We sought to characterize the antilisterial effects of a commercial GSE preparation (Gravinol-S) alone at much lower concentrations (0.00015 to 0.125%) in aqueous solution and to test its possible use as an antimicrobial wash for fresh produce surfaces. Based on broth microdilution tests, the MICs of GSE against L. monocytogenes Scott A and Listeria innocua ATCC 33090 were as low as 50 and 78 μg ml−1, respectively. GSE was evaluated in 0.85% saline against live cells of L. innocua via flow cytometry, using propidium iodide as a probe for membrane integrity. At sub-MICs and after only 2 min of exposure, treatment with GSE caused rapid permeabilization and clumping of L. innocua, results that we confirmed for L. monocytogenes using fluorescence microscopy and Live/Dead staining. At higher concentrations (0.125%), GSE reduced viable cell counts for L. monocytogenes by approximately 2 log units within 2 min on tomato surfaces. These results suggest the potential for GSE as a natural control of Listeria spp. on low-complexity foods such as tomatoes.
