Prevalence and Incidence of Periodontitis


advertisement

About prevalence and incidence statistics: The term 'prevalence' of Periodontitis usually refers to the estimated population of people who are managing Periodontitis at any given time. The term 'incidence' of Periodontitis refers to the annual diagnosis rate, or the number of new cases of Periodontitis diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Incidence (annual) of Periodontitis: 94,482 annual cases in Victoria 1996 (DHS-VIC)
Incidence Rate: approx 1 in 48 or 2.07% or 5.6 million people in USA [about data]
