Oral Epidemiology and Public Health Dentistry are pivotal in shaping community dental health policies. Oral Epidemiology studies the frequency, causes, and distribution of dental diseases, helping to identify the high-risk groups. Public Health Dentistry translates these findings into effective public health strategies, including preventive programs, health education, and advocacy for better oral health care. By addressing issues like dental caries, gum disease, and oral cancer, these fields contribute to reducing the prevalence of oral diseases in underserved communities. Their collaboration ensures that dental care is accessible, equitable, and tailored to the needs of different populations, enhancing public health outcomes.
