    • - undiagnosed
    • - carriers
    • The water line  demarcation between apparent and

    • 1. Of proven efficacy in the reducton of the targeted disease.
    • 2. Medically and dentally safe.
    • 3. Easily and efficiently implemented, utilizing a relatively small amount of materials, supplies and equipment.
  • 17.
    • 4. Readily administered by non dental personnel.
    • 5. Readily available and accessible to large numbers of individuals.
    • 6. inexpensive, therefore affordable by the majority.

  • 20.
    • Aims
      • Minimize / eradicate the disease of health problem and its consequences.
      • Minimize the chances of its occurrence in future
  • 21.
      • Objective
      • to define the magnitude and occurrence of disease conditions in man.
      • to identify the etiologic factors responsible for above conditions.
      • to provide data necessary for planning, implementation and evaluation of programmes for
      • - preventing
      • - controlling
      • - treating diseases
  • 22.
    • 2. Biostatistics
    • - statistics is the science of competing, classifying and tabulating numerical data and expressing the results in a mathematical / graphical form
    • - biostatistics is that branch of statistics concerned with mathematical facts and data relating to biological events.
  • 23.
    • uses
      • to define normally
      • to test whether the difference between two populations, regarding a particular attribute is real or a chance occurrence
      • to study the correlation or association between two or more attributes in the same population

DIFFERENCES BETWEEN PRIVATE DENTAL PRACTICE AND PUBLIC HEALTH DENTISTRY Characteristic Private Dental Practice Public Health Dentistry Target Individual patient community or group of individuals Collection of information History taking and oral clinical examination Analysis of available health and morbidity records
  • 36. Differences… Special investigations Radiography, blood test, biopsies, exfoliative cytology Epidemiological surveys Conclusions Diagnosis Situational analysis of oral health status and needs and utilization of services
  • 37. Differences… Remedial Measures Treatment plan based on diagnosis, patients attitudes and affordability Action plan based on demands, available resources and priorities Major emphasis Curative and restorative care Promotive and preventive care
  • 38. Differences… Requirements for success Patient’s consent and co-operation Community Participation Service provider Dentist alone, sometimes with an assistant Health team professionals and para professionals, community volunteers
  • 39. Differences… Intervention Appropriate dental procedure Promotive and preventive measure at individual and community level Supportive Disciplines Psychology Sociology, Social psychology, Education, Epidemiology and Biostatistics
  • 40. Differences… Organization & Management Not relevant Very relevant Perspective Immediate Long term Evaluation & Results Relief of symptoms and restoration of function Formal programme evaluation
  • 41. Differences… Aftercare Recall, Further sittings Continuing care, Self care Funding Generally by the patient Generally by Government or Local authorities
  • 42. SERVICES PROVIDED THROUGH PUBLIC HEALTH DENTISTRY
    • Health education
    • Dental Health camps
    • Dental treatments  Extraction
