Chapter 26: Studying the Epidemiology of temporomanibular Disorders: Epidemiology
          
Definition of Epidemiology
Epidemiology is defined as "the study of the distribution, determinants and natural history of disease in populations" (Lilienfeld and Lilienfeld, 1980).

Inherent in this definition of epidemiology are three perspectives (Dworkin et al., 1992) which are examined in the screens that follow:

  • The population perspective
  • The developmental perspective, and
  • The ecological perspective.
