Association between Live Dietary Microbes and Root Caries: A Cross-Sectional Study with a Predictive Risk Model.

Higher intake of live dietary microbes was associated with a lower prevalence of root caries. Although the cross‑sectional design precludes causal inference, the findings suggest a potential link between dietary microbes and oral health. The proposed model may aid clinicians in identifying individuals at high risk and in developing targeted preventive strategies.
