“…Psychosocial factors such as loneliness or social isolation may also be of importance for the association between oral health-related quality of life and both outcomes of our study. Actually, previous studies repeatedly showed an association between low oral health-related quality of life and high loneliness levels [ 39 – 41 ]. High loneliness and isolation levels are also associated with low mental health [ 42 ].…”

Background There is limited knowledge regarding the association between oral health-related quality of life and probable depression and anxiety. Our objective was to examine the association between oral health-related quality of life and probable depression and anxiety in the German population (stratified by sex). Methods In sum, n = 3,075 individuals took part in a nationally representative survey (August/September 2021). The well-established Patient Health Questionnaire-9 (PHQ-9; cut-off of 10) and the Generalized Anxiety Disorder-7 (GAD-7; cut-off of 10) were used to quantify probable depression and anxiety, respectively. Results The likelihood of probable depression was significantly associated with lower oral health-related quality of life in the total sample (OR: 1.21, 95% CI: 1.18–1.25) and in both women and men. Additionally, the likelihood of probable anxiety was significantly associated with lower oral health-related quality of life in the total sample (OR: 1.17, 95% CI: 1.14–1.21) and in both women and men. Conclusions Our study emphasized the association between lower oral health-related quality of life and probable depression as well as anxiety in the general adult population in Germany. Future longitudinal studies are required to confirm our findings.

“…A number of studies have examined the factors contributing to loneliness and isolation covering socioeconomic factors, factors related to lifestyle, psychosocial factors and factors related to health ( 5 , 6 ). Some studies have also examined the association between oral health and loneliness as well as social isolation ( 7 – 10 ). However, thus far, a systematic review and meta-analysis is lacking systematically synthesizing this evidence.…”

Objectives Thus far, some empirical studies have investigated the association between oral health and loneliness as well as social isolation. However, a systematic review and meta-analysis is lacking synthesizing this evidence. Hence, our purpose was to close this knowledge gap. Design Systematic review and meta-analysis. Setting and Participants Observational studies examining the association between oral health and loneliness or social isolation were included. Disease-specific samples were excluded. Methods We searched three electronic databases (PubMed, PsycINFO, CINAHL), and did an additional hand search. Data extraction covered methods, sample characteristics and main findings. To evaluate study quality/risk of bias, the NIH tool was used. Study selection, data extraction and assessment of study quality were each conducted by two reviewers. Results Seven studies were included in our current work. Several cross-sectional studies and one longitudinal study reported an association between poorer oral health and higher loneliness as well as higher social isolation. The quality of the studies was mostly fair, with two studies of high quality. The pooled OR was 1.47 (95% CI 1.24–1.75) among the studies with adult samples. Conclusion Most of the included studies demonstrated an association between oral health and loneliness or social isolation. There is a lack of high quality studies on these associations; in particular, future studies should use longitudinal data to clarify the directionality between oral health and loneliness or social isolation.

“…Research demonstrates that being in isolation causes stress, malaise and depression and may disrupt the daily routine [21]. Maintaining it for a longer period may lead to serious health disorders [22]. These dependencies may lead to loneliness, social isolation [23] and reduced quality of life, which is, unfortunately, often observed more and more among the elderly, who are deprived of contact with other people [24].…”

Analog space missions were created to study the human factor in extraordinary conditions that would occur in future space habitats. Isolation has been shown to cause stress and disrupt individuals’ daily routine, which can also affect their oral hygiene and lead to an increased risk of dental caries and gingivitis. The astronauts’ specific freeze-dried diet is associated with “lazy” chewing, potential dehydration and vitamin A deficiency, which may adversely affect their saliva. The aim of this study is to investigate the influence of the freeze-dried diet on selected oral hygiene indicators in analog astronauts (AA) enduring strict isolation conditions during six consecutive analog space missions at the LunAres Research Station. During the experiment the oral hygiene and gingival inflammation status measurements were conducted on the group of AAs at the beginning and at the end of each mission. Measurements included four oral hygiene indicators: API, sOHI, PI by Silness and Loe and GBI by Ainamo and Bay. Each AA’s individual scores were noted and analyzed. Statistically significant reduction in the amount of plaque and intensity of gingival bleeding was observed over the course of the study, which could indicate positive results of applied oral hygiene procedures despite unfavorable dietary and stressful isolation conditions.
