==Prevalence of Periodontal Diseases in Adults==

Many studies look at the prevalence of “advanced [[periodontitis]]”, but have differing definitions of this term. Generally though, severe forms of periodontitis do not seem to affect more than 15% of the population of [[Industrialization|industrialized]] countries. The proportion of such subjects increases with age and seems to peak between 50 and 60 years. A later decline in prevalence may be due to [[tooth loss]].

 

Eres 2009 examined 3,056 students between the ages of 13 to 19 years at [[State school|public school]]s in [[Turkey]]. Their mouths were coded according to the recommendations of the CPITN ([[Community Periodontal Index of Treatment Needs]]). Among the 3,056 students screened, 170 were scheduled for further examination and 18 were diagnosed with localized aggressive periodontitis. Thus, the prevalence of LAgP was 0.6% with a female to male ratio of 1.25:1.{{Citation needed|date=October 2010}}

 

Baelum 1997 reported on the incidence of tooth loss over 10 years among adult and elderly Chinese and looked at some [[predictive factor]]s. There were 440 subjects, 8 of which were [[edentulous]] at baseline and 31 who lost all remaining teeth during the study period. Of the 401 who remained dentate, the incidence of tooth loss ranged from 45% in the 20-29 year old group to 96% in the 60 years plus group. He found that the best baseline predictors of tooth loss of all remaining teeth was that at least one tooth had attachment loss greater or equal to 7mm. As in other studies, a major portion of the total number of teeth lost was accounted for by a small group of persons. In this study, [[dental caries]] was the dominant reason for tooth loss.
