A Comparison of Yogurt and Probiotic Supplements Effects on the Hardness of Tooth Enamel: An In vitro Study

The demineralization of tooth enamel, which can be triggered by acidic foods and drinks at pH < 5.5, initiate dental caries. Yogurt probiotic supplements are that often consumed to help digestive function improve the immune system. However, both have a low pH, thereby, long time consumption trigger process. This study aims evaluate enamel hardness after applying yogurt supplements, was carried out experimentally in laboratory with one-group post-test design. sample used is 9 human maxillary premolars each treatment group. group comprises test material, such as well one control artificial saliva. Dental samples were immersed material for 96 hours, level measured Micro Vickers Hardness tester. T-paired showed soaking does not significantly affect indicated p-value 0.016. effect significant p=0.004. results different from reducing hardness, evidenced Post Hoc (LSD) (p=0.464). Conclusively, decreased less than supplements.
