“…Although many previous studies have reported a negative correlation between education level and caries, a statistically significant correlation was not detected in this study [31]. This may be due to the generally low education level among the participants.…”

Background Elder population is considered as a vulnerable group with high risk of dental caries. The older adults living in rural areas of Yunnan province account for approximately half of the province’s total population. However, few studies have addressed their dental caries status. The purpose of the present study was to investigate the dental caries status and its associated factors among 65-74 years old people in the rural areas of Yunnan province, China. Methods This cross-sectional study recruited participants through a multistage and stratified strategy, and comprised a clinical oral examination and a questionnaire survey. Two trained and calibrated dentists, wearing LED headlights, conducted the clinical assessment with dental mirrors and CPI probes. Caries experience was measured using the DMFT and DF-root indices. A face-to-face questionnaire survey was conducted to collect the participants’ socio-demographic information, oral health-related knowledge and practices. A multi-factor ANCOVA test was used to detect the factors influencing dental caries. Results 1175 elderly residents aged 65-74 were included. Of them, a majority of the surveyed elderly respondents (87%) experienced dental caries (DMFT>0), and 56% of the respondents had root caries. Their overall mean DMFT and DF-root scores were 10.4±10.9 and 2.4±3.8, respectively. In total, 12% of the participants were edentulous. In the final model, female, divorced or widowed elderly who living in Jianchuan district had higher mean DMFT scores. Conclusion The dental caries status among 65-to 74-year-old in the rural areas of Yunnan province, China, was poor. Their caries experience varied by gender, marital status and location. Cost-effective prevention and treatment programs should be implemented.

Background: Elder population is considered as a vulnerable group with high risk of dental caries. The older adults living in rural areas of Yunnan province account for approximately half of the province’s total population. However, few studies have addressed their dental caries status. The purpose of the present study was to investigate the dental caries status and their associated factors among 65-74 years old people in the rural areas of Yunnan province, China. Methods: This cross-sectional study recruited participants through a multistage and stratified strategy, and comprised a clinical oral examination and a questionnaire survey. Two trained and calibrated dentists, wearing LED headlights, conducted the clinical assessment with dental mirrors and CPI probes. Caries experience was measured using the DMFT and DF-Root indices. A face-to-face questionnaire survey was conducted to collect the participants’ socio-demographic information, oral health-related knowledge and practices. A multi-factor ANCOVA test was used to detect the factors influencing coronal and root caries. Results: 1175 elderly residents aged 65-74 were included. The majority of the surveyed elderly respondents (87%) experienced coronal caries (DMFT>0), and 56% of the respondents had root caries. Their overall mean DMFT and DF-root scores were 10.4±10.9 and 2.4±3.8, respectively. In total, 12% of the participants were edentulous. In the final model, female (β = 2.872, p < 0.001) and residents who living in less developed areas (Jianchuan district) (β = 9.601, p < 0.001) had higher mean DMFT scores. DF-Root scores were also higher among female (β = 0.739, p < 0.001), residents who living in less developed areas (Jianchuan district) (β = 2.082, p < 0.001). In addition, elderly who had lower annual family income were more likely to had more root caries (β = 0.642, p < 0.001) . Conclusion: The dental caries status among 65-to 74-year-old in the rural areas of Yunnan province, China, was poor. Their coronal and root caries experience both varied by gender and place of residence. Cost-effective prevention and treatment programs for caries management should be implemented to benefit the elderly population in the rural areas of Yunnan province.

“…In another cross-sectional study in 2017 which sought to determine the association between SES and dental caries in elderly people in Sichuan Province, China, the burden associated with dental caries remained high in disadvantaged, poor and older populations 15 . In addition, a systematic review and meta-analysis study in 2015 which explored socioeconomic inequality and dental caries found that those with lower educational level or lower income, were most likely to have a higher risk of caries lesions 16 .…”

Background: Dental caries is the most common chronic oral condition affecting millions of people worldwide. There are several predictors of dental caries that include amongst others water source, fluoride use, smoking status, alcohol use, employment status, level of education, diet and socioeconomic status. Aim: The aim of this study was to determine the risk factors and or predictors associated with dental caries among adults attending dental clinics at public health facilities in eThekwini and uMgungundlovu districts in the KwaZulu-Natal (KZN) province of South AfricaSetting: The study took place at thirteen dental public health clinics in eThekwini and six from uMgungundlovu districts in KZN province, South AfricaMethods: An observational cross-sectional study was conducted over a 5-month period from November 2018 to the end of March 2019 with a sample of 4716 patients of all adults 18 years and above age groups. A clinical examination as well as a close-ended questionnaire on the diagnosis, basic demographics data, socioeconomic status (SES), as well as lifestyle-related questions such as smoking, alcohol use and dietary choices, was administered to all consenting participants. Bivariate analysis and multivariate analysis using logistical regression were used to measure the association.Results: Females participants OR 1.4 (95% CI 1.2-1.6) p < 0.001**, patients consuming an unhealthy diet OR1.2 (95% CI 1.2-1.6) p < 0.001** were more likely to develop dental caries. Patients Achieving more than secondary level education were OR 0.8 (95% CI 0.7-0.9) p = 0.02* less likely to develop dental caries. Despite showing a slightly increased odds ratio OR 1.25 (95% CI 0.93-1.67) p = 0.14, lack of access to water was not a statistically significant contributor to dental caries.Conclusion: This study showed that female sex, consumption of an unhealthy diet and lower than a secondary level of education were the predictors of dental caries. It is hoped that these findings will contribute in influencing dental public health policy planning to ensure that planning for dental services takes a more comprehensive approach that includes health promotion, primary prevention, secondary prevention and tertiary prevention at appropriate levels of the health system.
