It can be defined as the science and art of preventing disease, prolonging life and promoting health and efficiency through organized community efforts for sanitation of environment, control of communicable infections, education of individuals in personal hygiene, organization of medical and nursing services for early diagnosis and preventive treatment of diseases and development of social machinery to ensure for every individual a standard of living adequate for maintenance of health, so organizing these benefits to enable every citizen to realize his birth right of health and longevity.
The science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts.

Mc.Hugh: It is that branch of dentistry which is practiced in relation to population and groups, which derive from epidemiology an awareness of service required and which include the development of technique necessary to organize the application of these services for the benefit of the population.

Defined as including all the personal health and environmental services in any human community, irrespective of whether such services were public or private ones.
It can be defined as a science and art of promoting and preventing the onset of oral and dental diseases and treatment of these diseases in their early stages and prolonging the life by promoting dental or oral health as well as physical and mental health and efficiency of the individuals, families, groups and communities.

Deals with the population and comprises those doctors who try to measure the needs of the people both sick and well, who plan and administer services to meet those needs and those who are engaged in research and teaching in the field.
Refers to the identification and quantification of health problems in a community in terms of mortality and morbidity rates and ratios and the identification of these correlates for the purpose of defining those individuals or groups at risk or those in need of pulp care.
Parkin (1873): As the branch of medical science which deals with the treatment of epidemics.
Englander (1962): The study of those factors which influence the occurrence and distribution of health, disease, defect, disability and death in population.

National conference on preventive medicine USA is defined as the process which informs, motivates and helps people to adopt and maintain healthy practices and lifestyles, advocates environmental changes as needed to facilitate this goal and conducts professional training and research to the same end.

Defined as an organization that is administered by an autonomous board which holds meetings, collects funds for its support chiefly from private sectors and expends money with or without paid workers in conducting a programme directed primarily to furthering the public health by providing health education by advancing research or legislation for health or combination of these activities.
Community dentistry has two aspects:
  1. Community diagnosis
  2. Community treatment.
It is a systematic study of community dental and oral health status through epidemiological surveys.
6The following data should be collected:
  1. Demographic pattern of the community.
  2. Socioeconomic conditions of the people.
  3. Incidence and prevalence rate of dental and oral diseases.
  4. Identification of dental and oral health problems and treatment needs.
  5. Identification of high risk and vulnerable group of people.
  6. Identification of resources in the community.
It aims at planning the oral health programmes and schemes for carrying out oral health and other services required to solve community oral health and other problems. Importance should be given to the FELT NEEDS of the community.
Community oral health is the organization of an array of promotive, preventive and curative oral health services required at individual and community level for the people living in a community.
The American Board of Dental Public Health modified Winslow's definition of public health as the science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts.
It is that form of dental practice that serves the community as a patient rather than an individual. It is concerned with dental health education of public, with research and the application of findings of research, with administration of dental care programme for groups and with prevention and control of dental diseases through a community approach.
It is the concept that oral health service should be aimed at the community level rather than the individual patient level with scientific approach.
It renders the application of principles of Epidemiology, Health Administration, Dental Health Education, Biostatistics, Behavioural Science and Sociology.7
Applying only scientific principles and arriving at community diagnosis is not sufficient for successful community treatment. The art of dental public health has to be developed. The essential features of the art of community health are:
  1. To give priority for the FELT NEEDS
  2. To establish co-operation between the health care beneficiaries and providers
  3. To utilize all the existing resources with maximum efficiency
  4. To establish easy access to health services
  5. To give priority to high risk and vulnerable group of people
  6. To make health services available and affordable to all
  7. To provide comprehensive dental health care.
  1. Health promotion for the entire population.
  2. The detection and eradication or control of those factors operating in the community which are imminent to oral health and community well-being.
  3. To assess the needs of dental care of the community.
  4. Determination of procedures and statement of objectives.
  5. Determination of available resources for programme implementation.
  6. Improvement of community oral health by:
    1. Implementing effective preventive and therapeutic measures.
    2. Deploying the available resources to meet the needs on the basis of priority.
    3. The measurement of effectiveness of present services and planning of new services.
    4. The co-ordination and integration of dental services and health services.
  7. Providing treatment services to persons who do not have easy access to general practitioner.
  8. Establishment and maintenance of community laboratories.
  9. Co-ordination and participation in the teaching of dental public health and in preventive practices to students, teachers, health educators, dieticians, doctors and nurses.
