Epidemiology of periodontal disease in adolescents in mainland China, 1983–2020: a systematic review and meta-analysis

Abstract

Background: Periodontal disease is a chronic inflammatory disease that includes primarily gingivitis and periodontitis, caused by bacterial infection of the supporting structures of the teeth. For years, much attention has been diverted to periodontal disease among the elderly, not enough attention is paid to adolescents. The purpose of this meta-analysis is to evaluate the epidemic trend of periodontal disease in adolescents in mainland China.Methods: We conducted a comprehensive literature search through PubMed, Embase, CNKI, Chongqing VIP database, Chinese Wan Fang Database, and CBM. A series of subgroup analyses were done to explore the epidemiological characteristics of periodontal disease (gender, location, age, survey year, and geographical distribution) with the help of related software.Results: Thirty studies were included in this study. The data extraction and analysis were from three indexes, including bleeding on probing (BOP), pocket depth (PD), and dental calculus (DC). The detection rates of BOP(+), PD ≥4 mm and DC(+) were 48.8% (95% CI: 36.2-61.4%), 1.0% (0.0-2.0%), and 49.8% (41.0-58.6%), respectively. There were significant differences for the prevalence of gingivitis both in gender and area: the prevalence was higher in males than that in females, and risk ratio was 1.04 (95% CI, 1.01-1.06); a lower prevalence in urban areas compared with rural areas, and the risk ratio was 0.90 (95% CI, 0.85-0.96). Conclusions:This study shows a high prevalence of gingivitis among adolescents in China. Higher-quality epidemiological surveys with standard examination criteria are needed.

Asociación de la enfermedad periodontal con factores de riesgo en adolescentes de 15 años de una institución educativa

“…Los hombres tuvieron una mayor prevalencia de la enfermedad periodontal que las mujeres, en una relación de 3 a 2. De igual manera se encontró el mismo resultado en la revisión sistemática que se llevó a cabo en adolescentes de China realizado por Xiao et al, y diversos estudios (21,22,23). Similarmente, Khan et al, mencionan que esto sucede debido a que los varones se encuentran más expuestos a diversos factores de riesgo, tales como un cepillado dental deficiente y el inicio temprano del consumo de tabaco (14).…”

Porphyromonas gulae infection in canines, pet owners and veterinarians in China: an epidemiological study and risk factor analysis

“…According to a statistical survey, approximately 80% of the adult population in China suffers from PD to varying degrees, during much of the researchers' attention [9]. The current incidence of gingivitis among Chinese adolescents is approximately 48.8%, which is higher than in developed countries [10]. In addition to swollen, painful gums, tooth loss, and bleeding, human PD can cause halitosis, which may have a significant negative impact on the social lives of patients.…”
