“…According to a previous study, the edentulism incidence in older Korean adults slightly increased due to the increase in older population in Korea. 21 Moreover, Silva-Junior, et al 18 reported a higher incidence of tooth loss in older adults. Using machine learning analysis, Cooray, et al 32 showed that older people predominantly had a high prevalence of tooth loss in Japan.…”

“…Nilsson, et al 20 showed a longitudinal evaluation of tooth loss in Sweden. In Korea, Go, et al 21 showed the incidence of edentulism among older Korean adults using the National Health Insurance Service big data, and Jung 22 showed the trends in prevalence with total tooth loss in Korean adults aged 60 years and older. However, the incidence of SPE in adults aged ≥20 years has not been fully elucidated in Korea.…”

Purpose Missing teeth is one of the most important indicators of oral health behavior and the result of dental caries, periodontal disease, and injuries. This study examined a trend in the incidence of severe partial edentulism (SPE) using the Korean National Health Insurance Service (KNHIS) data. Materials and Methods Data of adults aged ≥20 years were obtained from the KNHIS for the 2014–2018 period. SPE was defined in dental information within a population with a treatment history of dental scaling as having 1 to 8 natural teeth. Crude incidence rates (CIRs) and age-standardized incidence rates (AIRs) with 95% confidence interval were calculated per 100000 persons. The Cochran Armitage trend (CAT) test and average annual percentage change were used to analyze SPE trends. Results The CIRs among Korean adults were from 346.29 to 391.11 in 2014–2016 and from 391.11 to 354.09 in 2016–2018. The AIRs trend statistically increased by 4.31% from 346.29 to 376.80 and decreased by 4.72% from 376.80 to 342.10. The AIRs in men increased by 4.00% and decreased by 3.01%. The AIRs in women decreased by 2.18% and increased by 2.11% (CAT; p <0.01). The AIRs by region and income also showed trends of increase and decrease. Conclusion The study showed that the incidence trend of SPE increased and decreased from 2014 to 2018. This result would be able to aid in the planning of public oral health, and may also serve as fundamental data for verifying the impact of the public oral health policies implemented.

ObjectiveDental implants are a considerable financial burden for elderly people and their caregivers. This study aimed to calculate the estimated economic costs of dental implants on the Korean older population.Materials and MethodsThe economic costs of dental implants for adults aged 75 years and older were estimated from a societal perspective, considering both direct and indirect expenditures. We used data from the Korean National Health Insurance Service for the period 2015–2018 to estimate the medical costs. Noninsured medical costs were estimated from research on medical expenses by the National Health Insurance Review and Assessment Service. Indirect costs related to transportation fees and time loss were obtained. The Cochran Armitage trend test was performed to examine the trend of the economic burden of dental implants.ResultsThe estimated economic costs showed from 2015 to 2018 (total costs: $26.54–55.66 million, total costs after discount: $17.11–39.56 million). Direct costs, including insured and noninsured medical costs, represented from $25.81 to $47.03 million. Indirect costs, including transportation and time costs, ranged from $0.73 to $1.63 million. The impact of the total dental implant costs was 0.0018%–0.0034% of the Korean annual gross domestic product and 1.03%–1.59% of the annual total costs of dental care benefits.ConclusionsThe estimated economic burden of dental implants significantly increased from 2015 to 2018 in older South Korean adults. These results will provide a foundation and guidance for further health economic studies on the burden of dental implants in the elderly population.

Background Edentulism impacts the physical health and quality of life of older individuals. The prevalence, influencing factors, and differences in terms of edentulism in urban and rural areas of China are unclear. Objective This study investigated the denture-wearing conditions and causes affecting older patients with edentulism in urban and rural areas of China and analyzed the differences. Methods This cross-sectional study included the data of 5139 older individuals (age>65 years) with edentulism obtained from 23 Chinese provinces in 2018. Participants were divided into urban and rural groups based on their household registration. Factors influencing denture use in both groups were explored using binary logistic regression, while factors influencing differences in denture wearing in both groups were explored using the Fairlie decomposition model. Results Of the 5139 participants, 67.05% (808/1205) from urban areas and 51.12% (2011/3934) from rural areas wore dentures. In the urban group, participants with a higher level of education (1-6 years: odds ratio [OR] 2.093, 95% CI 1.488-2.945; ≥7 years: OR 2.187, 95% CI 1.565-3.055) or who exercised (OR 2.840, 95% CI 2.016-3.999) preferred wearing dentures, but individuals with BMI<18.5 kg/m2 (OR 0.558, 95% CI 0.408-0.762) or widowed (OR 0.618, 95% CI 0.414-0.921) did not. In the rural group, a higher level of education (1-6 years: OR 1.742, 95% CI 1.429-2.123; ≥7 years: OR 1.498, 95% CI 1.246-1.802), living alone (OR 1.372, 95% CI 1.313-1.663), exercise (OR 1.612, 95% CI 1.340-1.940), high economic status (OR 1.234, 95% CI 1.035-1.472), residence in the eastern area (OR 2.045, 95% CI 1.723-2.427), presence of chronic diseases (1 disease: OR 1.534, 95% CI 1.313-1.793; ≥2 diseases: OR 1.500, 95% CI 1.195-1.882) were positively associated and age≥80 years (OR 0.318, 95% CI 0.247-0.408), BMI<18.5 kg/m2 (OR 0.692, 95% CI 0.590-0.813), and widowed (OR 0.566, 95% CI 0.464-0.690) or other marital status (OR 0.600, 95% CI 0.392-0.918) were negatively associated with denture use. The Fairlie decomposition model revealed that the number of chronic diseases (16.34%), education level (11.94%), region of residence (11.00%), annual income (10.55%), exercise (6.81%), and age (–0.92%) were the main factors responsible for differences between urban and rural edentulism and could explain the difference in the denture-wearing rate (58.48%) between both groups. Conclusions Older individuals with edentulism with a higher education level and who exercise are more willing to wear dentures, while those with BMI<18.5 kg/m2 show a decreased willingness to wear dentures in both urban and rural areas in China. Controlling the number of chronic diseases, improving the education level and annual income, cultivating good exercise habits, and bridging the gap between the economic status of the east and west can narrow the differences in denture wearing among urban and rural older individuals with edentulism.
