“…What interested us was that the children who were exclusively/predominantly breastfed during the first half year of life had a higher risk of ECC. This finding agrees with the results of earlier studies reporting a significant relation between the duration of breastfeeding and ECC in young Chinese children [ 31 , 32 ], similar to its neighboring province of Zhejiang [ 11 ]. Part of the reason might be that breast milk is more likely to cause caries than other types of milk [ 33 ].…”

“…This survey reported high prevalence and severity of ECC among preschool children in Guangdong, Southern China, similar to the finding for East China [ 11 ] and higher than that for Southwest China [ 12 ], higher than the national average [ 13 ], and higher than that 10 years ago [ 4 ]. A multitude of factors are associated with the prevalence and severity.…”

Background Dental caries of deciduous teeth (Early Childhood Caries, ECC) has become a crucial oral health problem over the decades in China. The aim of this study was to examine the prevalence and severity of ECC among preschool children from Guangdong Province, Southern China. In addition, to assess the association of ECC with reported oral health-related behaviors. Methods A cross-sectional survey of 2592 participants was carried out in Guangdong Province by means of an equal-sized, stratified, multistage random sampling method during December 2015 and April 2016. The participants were divided into three groups according to their ages (3-, 4-, and 5-year-olds). Half of the participants were derived from urban areas, while the other from rural areas. According to the standard for clinical dentition examination of the WHO 2013 criteria, the presence of ECC was determined by the dmft (decayed-missing-filled tooth) index using a CPI (Community Periodontal Index) probe. A questionnaire about caries-related factors was completed by each of the participants’ parents or grandparents through a face-to-face and one-on-one interview. Then, t-test, Chi2 tests, One-Way ANOVA served for statistical analysis, and logistic regression analysis as well as covariance analysis were executed to identify potential associated factors for ECC. Results The prevalence (% dmft > 0) of ECC was 68.3 (95% CI: 66.5–70.1), the mean dmft was 4.36 (95% CI: 4.17–4.55), and the filled rate was 1.2%. In multivariable modeling, associated factors for both prevalence and mean dmft were older age, rural areas, consumption of sweets before sleep, dental visit history, low household income, and low parental education level. Initiating toothbrushing after 3 years of age and being exclusively/ predominantly breastfed indicated only the prevalence; being female and frequently consuming sweetened milk/powdered milk indicated only the mean dmft. Conclusions Preschool children in Guangdong Province, especially children from rural areas, experienced a significant amount of ECC. Associated factors for ECC included demographics, oral health measures, dietary factors, and socioeconomic factors. More attention should be given to prevention of ECC from early life. The construction of social support for oral health should be strengthened. Oral health education and promotion, especially of rural areas, should be intensified to reduce the inequality between urban and rural areas.

“…Province is much higher than that in Japanese (31.1%) 9 and English children (31.7%). 10 Compared with more developed countries such as Japan and England, Zhejiang is slower in terms of oral health promotion and treatment, which falls behind its economic development, 13 analysis showed that the prevalence of ECC increased significantly with age. 13 We believe that this is mainly attributed to the cumulative effect of age throughout life.…”

The American Children's Dental Association defines early childhood caries (ECC) as the presence of one or more cavities, missing teeth (due to caries) or fillings on the surfaces of teeth in children who are younger than 71 months. 1 Over the past few decades, ECC has become the most common oral disease in children, affecting children's health, growth, quality of life and even psychological status. 2 ECC is influenced by many factors, including genetic, dietary and environmental ones. Some studies showed that children's sugar intake and frequency, 3 breast-feeding time, 4,5 brushing frequency, 6 fluoride use, 7 children's body mass index 8 and even parents' smoking history 9 are all possible risk factors for ECC. China has been actively exploring methods to prevent and treat ECC by formulating policies on oral health for children and vigorously promoting oral health-related knowledge. A national oral health epidemiological survey is conducted every ten years. The fourth national survey (2016) showed that the incidence rate of primary tooth caries in children aged 3-5 years was 62.5% with a mean decayed, missing and filled teeth (dmft) score of 3.35. Compared this survey with the
