RESUMO
Dental caries remains a prevalent concern among children globally and is associated with Candida sp. Some researchers have suggested probiotic supplements as a possible solution for reducing dental caries. A study conducted in Tamil Nadu focused on collecting 80 dental caries samples from both males and females, obtained from two different locations. The samples underwent processing using the spread plate technique, followed by anticandidal activity assessments. Through ITS sequence analysis, candida strains were identified, including C. albicans (DDGRPO1, DDGRPO2). The study specifically investigated the ability of the probiotic bacterial strain Lb. fermentum cell-free filtrate to inhibit C. albicans. The research revealed that Lb. fermentum probiotics effectively inhibited the growth of C. albicans DDGRP01, displaying strong antifungal activity against Candida sp. (98%). While these results are promising, it is worth mentioning the increasing interest in exploring innovative alternatives to probiotic-based treatments. This avenue of research offers potential for a more comprehensive approach to addressing this issue. Notably, Lb. fermentum, derived from the human oral cavity, emerges as a significant postbiotic candidate for dental prophylaxis, indicating a hopeful direction for future studies.
