Summary: Based on the data from the German Oral Health Studies, it is predicted that by 2030, the average number of missing teeth in adults will decrease by two-thirds to 1.3, while the average number of missing teeth in seniors aged 65-74 will decline to 5.6, also a two-thirds reduction. The prevalence of tooth loss is expected to decrease by 72% by 2030, with half of the adult population and about one-third of seniors not exhibiting any tooth loss by that time.

Summary: This study examines the relationship between dental caries and malnutrition in children. The results suggest that the development of pulpally involved carious lesions has an effect on wasting outcomes, but not on stunting. This highlights the importance of oral health promotion and preventive measures in low-income settings to promote normal growth and development among preschool children.

Summary: The aim of this study was to evaluate the association between the lack of a functional dentition and edentulism with mortality in a cohort of older adults in a Southern Brazilian city. The findings of this study did not identify an association between edentulism and functional dentition with mortality, after considering important shared risk factors.

Summary: Oral conditions are common and chronic in the population. Identifying risk factors and determinants of oral diseases is crucial for improving oral health care systems and developing effective oral health promotion programs. Cohort studies are useful for studying risk factors in oral diseases and highlighting the importance of a healthy start for oral health.

Summary: The study suggests an association between oral health, depicted by number of natural teeth, and the increased risk of kidney diseases. The risk of end-stage renal disease was found to be higher with lower number of natural teeth and longer follow-up periods. Factors such as age, body mass index, and smoking status were also significantly associated with this relationship.

Summary: Social participation has a positive impact on the health and well-being of older adults in aging societies. This study in Japan focuses on the effect of retaining natural teeth on social participation. The findings suggest that tooth loss prevention scenarios improve social participation, while tooth loss scenarios gradually decrease it.

Summary: This study investigated whether the association between alcohol consumption and tooth loss is influenced by socioeconomic positions in Brazilian older adults. The results showed that heavy drinkers with low socioeconomic status and low educational attainment had a higher prevalence of tooth loss compared to their counterparts. This association was confirmed in sensitivity analyses.

Summary: The study found that during the postpartum period, consuming a diet high in desserts and crackers may increase the risk of dental caries, but this effect is attenuated among those who also consume a diet high in fruits and vegetables. Dietary patterns should be considered when devising interventions aimed at preventing dental caries.

Summary: This article reviews the survival of teeth after root canal treatment and focuses on the factors that affect tooth survival. The study found that tooth restoration is the most important factor associated with the success of root canal treatment. Indirect restorations were found to have a higher survival rate compared to direct restorations.

Summary: Many studies suggest associations between oral health and cardiovascular diseases, but there is a lack of causal evidence. This study investigated the causal effect of tooth loss on cardiovascular diseases by exploiting the relationship between tooth loss and childhood exposure to fluoridated water. The findings supported a causal effect of tooth loss on coronary heart disease and stroke.

Summary: This study aimed to investigate the impact of social isolation on depression among older adults and found that social isolation increased the risk of elevated depressive symptoms, especially for women. This research is of great importance for future interventions to reduce depression among elderly individuals.

Summary: This study aimed to examine the impact of income levels on cardiovascular risk factors among men and women aged 30-49 years. The results showed that over the past 4 years, the low-income group consistently had higher prevalence of obesity, hypertension, and diabetes compared to the high-income group, and this gap has been increasing. Therefore, careful monitoring of the growing social disparities is necessary to achieve cardiovascular health equity at this life stage.

Summary: Japan has experienced a decline in fertility due to the COVID-19 pandemic, particularly its adverse economic conditions. This study examined the rate of pregnancy postponement and its contributing factors, finding that declining income and concerns about future household finances were significant factors. Fear of COVID-19 and infection rate did not have a significant impact. The adverse effects of unfavorable economic conditions were stronger in 2021.

Summary: Despite the recognition of economic factors as key determinants of health inequalities, interventions have traditionally focused on more direct health-related factors. However, recent socioeconomic crises have highlighted the importance of economic factors. There are two approaches to addressing economic factors in relation to health: indirect approaches, such as financial support for dental care, and direct approaches, such as cash transfers or basic income. Indirect approaches, such as reducing out-of-pocket payments for dental care, can improve access and reduce oral health inequalities. Price policies targeting tobacco and sugar through taxation have been associated with declines in periodontal disease and caries, and sugar taxation appears to reduce oral health inequalities.

Summary: This study compared education-related oral health inequalities in older adults in Singapore and Japan. The results showed that older adults in Singapore had higher rates of being edentate and having a minimal functional dentition, as well as greater education-related inequalities in oral health compared to those in Japan.

Summary: The study explored the underlying mechanisms of the association between lower socio-economic status (SES) in adolescence and poor oral health at an older age. The results showed that lower SES in adolescence was associated with higher prevalence of chewing difficulty and fewer remaining teeth in old age. Mediators, such as the number of teeth and income, explained 39.3% of the associations. The findings highlight the importance of considering social determinants from early life stages.

Summary: Evidence suggests a longitudinal association between tooth loss and cognitive function. The temporality of this association was investigated by simulating tooth loss prevention scenarios using data from the Panel on Health and Ageing of Singaporean Elderly (PHASE). The study found that preventive interventions for tooth loss were associated with better cognitive function among older adults.

Summary: This study aims to identify the factors associated with social isolation and loneliness among older adults in Japan and describe the characteristics of socially isolated but not lonely individuals, as well as lonely but not socially isolated individuals. The findings indicate that higher age, male gender, lower socioeconomic status, being a welfare recipient, and having depressive symptoms are associated with social isolation among older Japanese adults. Additionally, lower socioeconomic status, unemployment, welfare receipt, and poor physical and mental health are associated with loneliness.
