The prevalence and severity of periodontal disease in Mainland China: Data from the Fourth National Oral Health Survey (2015–2016)

Abstract

AimTo evaluate periodontal conditions in adults in mainland China based on data from the 4th National Oral Health Survey.Materials and methodsData of adult subjects (35‐ to 44‐year‐old group [N = 4409], 55‐ to 64‐year‐old group [N = 4622], and 65‐ to 74‐year‐old group [N = 4428]) were analysed. Demographic, socio‐economic, personal habit, dental history, and health attitude data were obtained using a questionnaire. Periodontal condition was assessed using the standardized case definitions of the 2018 classification scheme. A multivariate analysis was performed to investigate the relationship between periodontitis severity and age, smoking status, gender, and region using generalized additive models after adjusting for confounders.ResultsThe frequency of subjects with periodontitis was 52.8%, 69.3%, and 64.6% in the three age groups, respectively. The frequency of subjects with severe periodontitis (stage III or IV) was 10.6%, 37.3%, and 43.5% in the three age groups, respectively. The severity of periodontal disease was positively associated with age. Current and former smokers exhibited significantly greater disease severity than non‐smokers after adjustment for confounders. No significant difference of severity was found between males and females.ConclusionWithin the limitations of the study, the prevalence of periodontitis is very high among adults in mainland China. Periodontal status is associated with age and smoking status.

Periodontitis Prevalence, Severity, and Risk Factors: A Comparison of the AAP/CDC Case Definition and the EFP/AAP Classification

“…When the maximum PD value was added when determining complexity, the distribution of periodontitis stages changed dramatically (Table 3). Only a few epidemiological studies have used the new classification [12,[24][25][26][27][28]. However, the epidemiological surveys did not clearly explain how complexity was used to determine periodontitis staging.…”

“…A rigorous analysis of evidence supposedly supporting the roles of various risk factors in terms of periodontitis prevalence and severity is very important when diagnosing and treating periodontal disease. The periodontitis prevalence varies among both developed and developing countries [8][9][10][11][12][13][14]. The historical lack of a standard periodontitis definition facilitating surveillance precludes any meaningful comparisons of findings in terms of variations in socioeconomic status, ethnicity or exposure to risk factors.…”

The imbalance of Th17/Treg via STAT3 activation modulates cognitive impairment inP. gingivalis LPS-induced periodontitis mice

“…Periodontitis, a microbial‐related, multi‐factorial inflammatory disease that causes the loss of periodontal attachment, widely affects adults globally 1,2 . According to epidemiological investigations, the prevalence of periodontitis in adults of age 65–74 years in mainland China is 64.6%, with a 43.5% prevalence for severe periodontitis 3 . Evidence has suggested that periodontitis accelerates systemic diseases, such as respiratory tract infections, diabetes, cardiovascular disease, and cognitive impairment 4–6 …”

Urban-Rural Disparities in Dental Services Utilization Among Adults in China's Megacities

“…According to the 4th National Oral Health Epidemiology Survey conducted between 2015 and 2016 in China, the prevalence of dental caries is more than 90.0% for adults between the ages of 35 and 74 years old [1]. Furthermore, the prevalence of periodontitis among middleaged adults ranging from 35 to 44 years old is 52.8% [2]. Such oral health diseases and problems are associated with a lack of dental services utilization [3][4][5].…”
