Associated factors of dental caries among middle-aged adults in Guizhou Province, China (2019–2020)

The prevalence of dental caries remains globally high, as reflected in both developing and developed countries. Targeted interventions, particularly for females, urban residents, and ethnic minorities, are recommended. Public health initiatives should prioritize promoting safer oral hygiene practices and smoking cessation programs, including education on managing post-cessation cravings for sugary foods. Further research, including longitudinal studies, is needed to evaluate intervention effectiveness.
