This document provides an introduction to dental public health and community dentistry. It discusses key topics including the definition of dental public health, the role of dental practitioners in both private and community practice, epidemiology and its uses in dental health, and the different levels of preventive services including primary, secondary, and tertiary prevention. The goals of dental public health are outlined as educating the public, preventing and controlling dental diseases, applied dental research, and providing treatment programs.

1. Introduction to dental community DR. Rabab Salama

2. Health is status of complete physical, mental and social efficiency not only absence of the diseases ( WHO definition). Health

3. Dental public health Deals with the whole community rather than the individuals so, it called community dentistry. Public health is health of people in certain community

4. Dental public health The art and science of preventing and controlling dental diseases in addition to promoting the dental health through organized community efforts.

5. Dental public health concern with

6. 1.Dental health education to the public. 2.Preventing and controlling of dental diseases. 3.The applied dental researches. 4.Providing dental care programs that include the prevention and treatment.

7. Aim of the dental public health course

8. 1.To give better understanding of the patient that should be treated as a part of the community rather than a specific case that needs treatment. 2.To realize the importance of implanting the future dental practice based on the regular maintenance of care and utilization of preventive measures.

9. 3.To provide the specialized skills and knowledge that will enhance the future practice dentistry. 4.To identify the community health problems and suggest approaches for their correction.

10. The Role of Dental Practitioner assessing, reviewing, and recording a patient’s risk for dental diseases, oral health status and to “prescribing” an appropriate treatment.

11. Role of dental practitioner in private and community practice

12. I. Private dental practice II. Community dental practice 1.Survey of the community oral health status and their demographic characters. 2.Analysis of the survey data to determine health needs. 3.Program plan based on the resources available and priorities 4.Financing takes place . 5.Evaluation of the program progress. 1.Assessment of dental, medical history and oral health status. 2.Diagnosis of the patient oral health. 3.Treatment plan based on diagnosis and patient needs and priorities. 4.Payment method is determined. 5.Evaluation during treatment at specific interval

13. Epidemiology Epidemiology is derived from three Greek words

14. Definition of epidemiology The study of the health and the disease in human population and how these statuses are influenced by the environment and way of living.

15. Uses of epidemiology Study the pattern of the diseases among population. Collection of data to understand the natural history to the disease which lead to formulation of hypothesis to explain the disease. Planning and evaluation of dental health services. To identify the etiological factors responsible for a disease. To identify special groups more susceptible to oral diseases and allow planning for preventive services.

16. Scientific methods in dental epidemiology 1.Formulation of the hypothesis. It aim to put the idea of the investigator in the form of a null hypothesis, which is the starting point of any investigation. 2.Designing the investigation, using the methods of epidemiological studies

17. 3.Selection of the sample. 4.Conducting the investigation, with the main three aspects when conduct the examinations The examination method. The diagnostic criteria. The indices used for measurements.

18. 5.Analysis of data. 6.Drawing the conclusion. 7.Publishing the results.

19. Types of epidemiological studies

20. Prevention of the oral diseases

21. Prevention of the oral diseases Many diseases are preventable through simple, non-medical methods as most common oral diseases (dental caries and periodontal diseases). Prevention of oral diseases depends upon data collected from the epidemiology of the diseases which can identify the etiological factors concern with the diseases and find the methods to control or prevent it.

22. Prevention can divided into the following levels of preventive services 1-Primary-Primary preventive services: It is instruction and education of expectant mother (pregnant) to keep good oral hygiene of the child and include prevention

23. 2-Primary preventive services: It is to prevent the initiation of the disease; they are designated as service that provides: Health promotion and specific protection.

24. Specific protection activity includes services that are designated to protect against disease agent by decreasing the susceptibility of host or by establishing barrier against environment

25. It is the prevention and reversing the progress of initial stages of disease or to arrest the disease progress before treatment become necessary e.g. Remineralization of carious lesion, fluoride, and dental sealant.

26. 3-Secondary preventive services: It is the employs routine treatment method to terminate a disease process and to restore tissue to as near as possible e.g. restorative treatment, endodontic treatment, and periodontal treatment. It is included the early diagnosis and the prognosis of treatment.

27. 4-Tertiary preventive services: These services directed toward the end result of disease, also can be referred as replacement therapy, these activities provide measures necessary to replace lost tissue and to rehabilitate patient to the point that function is near normal as possible e.g. prosthetic appliance and implant.
