Probiotic Enriched and Traditional Yogurt Extracts on Dental Enamel Demineralization- Comparative Study

Background: Dairy products were recognised in the late 1950s as food group exhibiting most anticaries activities. Yogurt, a dairy product, almost as commonly consumed as milk has been subjected to less research in the context of its effect on oral health, especially on dental enamel. AIM: To compare invitro the effectiveness of probiotic enriched yogurt extract and traditional yogurt extract in inhibiting dental enamel demineralization and promoting its remineralisation. Materials& methodology: Sixty intact caries free human premolars were selected and divided into three groups comprising 20 teeth in each group. Invitro demineralization procedures were performed at pH 4.8 on these three groups of teeth but with the addition of probiotic enriched yogurt extracts and traditional yogurt extracts on group1 and group2 respectively. The effects of these procedure were evaluated quantitatively by Atomic absorption spectrophotometer, (AAS) and qualitatively by confocal laser scanning microscopy, (CLSM). Statistical analysis of the results was performed using one way ANOVA. Results: One way Anova showed statistically significant difference between the three groups .CLSM and AAS analysis demonstrated more inhibitory effect of the traditional yogurt group compared to the probiotic enriched group. Conclusion: Traditional yogurt has more inhibitory effect than probiotic enriched yogurt on dental enamel demineralization.
