}Many definitions of periodontitis have been used in the literature for population-based studies, but there is no accepted standard. In early epidemiologic studies, the two major periodontal diseases, gingivitis and periodontitis, were combined and considered to be a continuum. National United States surveys were conducted in 1960 to 1962, 1971 to 1974, 1981, 1985 to 1986, 1988 to 1994, and 1999 to 2000. The case definitions and protocols used in the six national surveys reflect a continuing…Â

The Prevalence of Periodontitis in the US
- MedicineJournal of dental research
- 2012
New epidemiologic data on periodontal status derived from the 2009-2010 cycle of the National Health and Nutrition Examination Survey (NHANES) are published in this issue of the Journal of Dental Research and it is still unknown whether the partial NHANES methodology results in a consistent degree of bias across different levels of extent and severity of periodontitis.

The present text limited the present text to epidemiologic studies published over the past decade, anticipating that they would have utilized the 1999 World Workshop nomenclature, and addressed the issue of disease onset and the impact of age in the determination of diagnosis.
Update on Prevalence of Periodontitis in Adults in the United States: NHANES 2009 to 2012.
- MedicineJournal of periodontology
- 2015
A high prevalence of periodontitis in US adults aged ≥30 years is confirmed, with almost fifty-percent affected, and the prevalence was greater in non-Hispanic Asians than non- Hispanic whites, although lower than other minorities.
Underestimation of periodontitis in NHANES surveys.
- MedicineJournal of periodontology
- 2011
If a survey uses a partial-mouth examination it is recommended that the amount of underestimation be assessed in the same sample and inflation factors should be calculated and used to adjust for the underestimation in disease prevalence because of the use of partial examination.
Do the clinical criteria used to diagnose periodontitis affect the association with prematurity?
- MedicineOdontology
- 2020
The findings suggest that the association betweenperiodontitis and preterm birth is influenced by the definitions of periodontitis used, and this should not be considered a cause for concern.

periodontitis (pockets greater than or equal to 4 mm) affected approximately 36% of the population and was usually found on only one or two teeth when present, while end-stage periodontal destruction requiring extraction of teeth was found in only 4% of all persons while less than 20% ofall missing teeth were listed as missing due to periodontals disease.

The aim of this study was to compare changes in periodontal status in a Swedish population over a period of 20 years, and it is seen that an increase in the number of individuals with no marginal bone loss and a decrease in the many individuals with moderate alveolar bone loss can be seen.

Analytical epidemiology of periodontitis.
- Medicine, BiologyJournal of clinical periodontology
- 2005
A conspicuous lack of uniformity in the definition of periodontitis used in epidemiologic studies, and findings from different research groups are not readily interpretable, means there is a clear need for longitudinal prospective studies that address hypotheses emerging from the cross-sectional data and include established risk factors as covariates along with new exposures of interest.
