The second national survey of oral health status of children and adults in China

Abstract

Objectives: To describe the oral health status of Chinese children and adults at national level in relation to location and province and to highlight changes in dental caries experience. Design: Cross‐sectional study, oral epidemiological survey based on WHO methodology, clinical examinations. Setting: National survey by National Committee for Oral Health. Subjects: Representative samples of provinces, districts, townships; cluster sampling including subjects aged 5, 12, 15, 18, 35–44 and 65–74. Each age group consisted of 23,452 participants, i.e. total of 140, 712 individuals. Results: At age 5, 76.6% were affected by dental caries and mean dmft was 4.5. Mean DMFT varied from 1.0 in 12‐year‐olds, 1.4 in 15‐year‐olds, 1.6 in 18‐year‐olds, 2.1 in 35–44‐year‐olds to 12.4 in 65–74‐year‐olds. In adults, caries experience was higher in females than in males. The effect of urbanisation on caries prevalence in children varied by province and age. Among adolescents and young adults caries levels were high in urban areas while caries experience was high for old‐age people of rural areas. At national level, changes in dental caries prevalence of 12‐and 15‐year‐olds were small. However, some provinces with extensive oral health programmes (e.g. Love Teeth Day) showed declining caries experience whereas provinces with limited preventive activities had increasing levels of caries. For all age groups, gingival bleeding and calculus were most frequent. Severe periodontal conditions were relatively rare. Conclusion: The systematic implementation of preventive oral care and community‐oriented health programmes are needed for the continuous promotion of oral health in China.

Periodontal Diseases in Greek Senior Citizens-Risk Indicators

“…These findings are in accordance with those observed in Croatia, Denmark, Germany, Ireland and Bulgaria (Artukovic et al, 2007;Krustrup et al, 2006;Schiffner et al, 2009;Whelton et al, 2007;Yolov, 2002), although in some other countries like France, Turkey, Hungary, China and Spain the most frequently observed condition in that age group was calculus (Bourgeois et al, 1999;Gokalp et al, 2010;Hermann, 2009;Hong-Ying et al, 2002;WHO, 2011). Severe periodontal conditions (CPI scores 3 and 4) were found in 59.9% of the population.…”

“…On the other hand, the average number of excluded sextants was high (2.36) suggesting a high prevalence of tooth loss. Similar findings have been reported for most other countries (Bourgeois et al, 1999;Hong-Ying et al, 2002;Kazeko & Yudina, 2004). The finding that frequent tooth brushing and flossing, as well as visiting the dentist for check-ups significantly affected the mean number of healthy and excluded sextants, emphasizes the role of good self-care practices on the maintenance of oral health.…”

Oral Microbiome Shifts From Caries-Free to Caries-Affected Status in 3-Year-Old Chinese Children: A Longitudinal Study

“…The inclusion of 3- to 5-year-old children in our study was based on the literature that this particular population suffered from high prevalence and rapid development of caries decay (Wang et al, 2002; Phipps et al, 2012), making them a clinically significant age group and good candidates for longitudinal studies on the natural progression of dental caries and its associated microbiome shifts. This age group is also considered as having a “relatively stable primary dentition” in Pediatric dentistry.…”

Oral health status of older people in residential homes in Saudi Arabia

“…The figures were slightly higher, however, compared with those in non-institutionalized older people in other countries. For example, DFMT levels are 13.5 in India [19] and 12.5 in China [20].…”

“…In China, the second national oral health survey revealed that the mean number of decayed and filled teeth was 2.5 at old age [20], and a study in India also reported a mean number of decayed teeth of 2.5 [19]. In a recent survey of 65 to 74-year-olds in Madagascar [24], the mean DMFT score was 20.2; untreated dental caries was high (DT = 5.3), whereas the number of restored teeth was low (FT = 0.4).…”
