This document discusses the concepts of dental public health. It defines public health as organized community efforts to prevent disease, promote health, and assess community health needs. Dental public health specifically aims to prevent and control dental diseases through community programs and education. The key roles of public health are to assess community health issues, develop policies to address them, and assure services are provided to all. Major achievements in public health include reducing infectious diseases and improving factors like motor vehicle safety. Healthy People 2020 sets national health objectives, and the Surgeon General's 2000 report emphasized disparities in oral health.
