Dental Public Health Practice Questions
Course Introduction
Dental Public Health is a branch of dentistry that focuses on the prevention and control of dental diseases, the promotion of oral health, and the improvement of the overall dental well-being of communities. This course explores the principles and practices of public health as they pertain to oral health, including the assessment of dental health needs, the planning and implementation of community-based oral health programs, and the evaluation of public health interventions. Students will also examine the impact of social, behavioral, environmental, and economic factors on oral health disparities, and learn strategies for advocacy, policy development, and effective communication to promote oral health at the population level.
