“…In the HABC study, partial and complete tooth loss were associated with increased respiratory mortality after adjustment for confounders. This finding was supported by two previous studies in older Japanese populations 6 , 50 . It has been suggested that eating difficulties along with tooth loss resulted in increased risk of respiratory mortality 6 .…”

Preventing deterioration of oral health in older age can be crucial for survival. We aimed to examine associations of oral health problems with all-cause, cardiovascular disease (CVD), and respiratory mortality in older people. We used cohort data from the British Regional Health Study (BRHS) (N = 2147, 71–92 years), and the Health, Aging and Body Composition (HABC) Study (USA) (N = 3075, 71–80 years). Follow-up was 9 years (BRHS) and 15 years (HABC Study). Oral health comprised tooth loss, periodontal disease, dry mouth, and self-rated oral health. Cox regression was performed for all-cause mortality, competing risks for CVD mortality, and accelerated failure time models for respiratory mortality. In the BRHS, tooth loss was associated with all-cause mortality (hazard ratio (HR) = 1.59, 95% CI 1.09, 2.31). In the HABC Study, tooth loss, dry mouth, and having ≥ 3 oral problems were associated with all-cause mortality; periodontal disease was associated with increased CVD mortality (subdistribution hazard ratio (SHR) = 1.49, 95% CI 1.01, 2.20); tooth loss, and accumulation of oral problems were associated with high respiratory mortality (tooth loss, time ratio (TR) = 0.73, 95% CI 0.54, 0.98). Findings suggest that poor oral health is associated with mortality. Results highlight the importance of improving oral health to lengthen survival in older age.

“…The number of residual teeth is clearly paramount to mastication. A study conducted in Japan demonstrated that the retention of more than 20 teeth is necessary for effective masticatory ability [37]. It is reasonable to suppose that low masticatory ability in older people caused by the loss of multiple teeth affects dietary choices and therefore reduces quality of life.…”

Background The impact of poor oral health on older adults’ quality of life is a public health problem. In this study, the mediating effects of dental status, occlusal condition, dysphagia, and masticatory performance on the association between xerostomia and oral health-related quality of life (OHRQoL) were assessed in the older adult population. Methods Stratified cluster sampling was used to recruit 1076 community-dwelling adults aged 65 years and older from Kaohsiung, Taiwan. Community care centers were randomly selected according to their geographic classifications (urban, rural, or mountainous areas). Assessments of dental status and occlusal condition were performed by dentists. Information on demographics, physical function, xerostomia, dysphagia and depression was collected through face-to-face interviews. Masticatory performance was evaluated using color-changeable chewing gum. OHRQoL was measured using the Geriatric Oral Health Assessment Index. Hierarchical regression models were used to assess the relationships between OHRQoL and physical function, dental status and oral function in older adults. Path analysis was used to estimate direct and indirect pathways between xerostomia and OHRQoL. Results Participants with xerostomia exhibited a 0.20 OHRQoL reduction (p < .001) compared with patients with no xerostomia, and the direct effect accounted for 83.3% of the total effect. Dysphagia and masticatory performance were found to exert significant mediating effects on the association between xerostomia and OHRQoL (βs = 0.20 and − 0.12, respectively; both p < .001; βs = 0.06 and − 0.09, respectively; both p < .05). Moreover, potential mediating effects of the number of functional teeth (βs = − 0.11 and − 0.43, respectively; both p < .001) and occlusal condition (βs = 0.09 and 0.13, respectively; both p < .05) on the relationship between xerostomia and masticatory performance were noted. Conclusions Dysphagia and masticatory performance may serve as pathways through which xerostomia affects quality of life. Early oral function intervention may be a valuable and actionable target for older adults to maintain quality of life. Our results further suggest that checkup and screening for oral dysfunction are essential to prevent or delay the onset of complications.

Background: The impact of poor oral health in older adults affecting their quality of life is a public health problem. This study assessed the mediating effects of dental status, occlusal condition, dysphagia and masticatory performance on the association between xerostomia and oral health-related quality of life (OHRQoL) in the older population. Methods: Stratified cluster sampling method was used to recuit 1100 community-dwelling adults aged 65 years and older from Kaohsiung, Taiwan. Community care centers were randomly selected based on their geographic classifications (urban, rural, and mountainous areas). Assessments of dental status and occlusal condition were performed by dentists. Information on demographics, physical function, xerostomia dysphagia and depression was collected using face-to-face interview. Masticatory performance was evaluated using color-changeable chewing gum. OHRQoL was measured using Geriatric Oral Health Assessment Index. Hierarchical regression models were utilized to assess the relationship between OHRQoL and physical function, dental status and oral function in older adults. Path analysis was used to estimate direct and indirect pathways between xerostomia and OHRQoL.Results: Participants with xerostomia had a 0.17 OHRQoL reduction (p< .001) comparing to the non-xerostomia, and the direct effect was accounted for 85.0% of the total effect. The dysphagia and the poor masticatory performance were found to have a significant mediating effect on the association between xerostomia and OHRQoL (βs = 0.17 and −0.09, respectively, both p< .001; βs = 0.05 and −0.08, respectively, both p< .001) moreover, potential mediating influences of the number of functional teeth (βs = −0.11 and −0.44, respectively, both p < .001) and poor occlusal condition (βs = 0.09 and 0.12, respectively, both p < .05) on the relationship between xerostomia and masticatory performance were obervered.Conclusions: Dysphagia and poor masticatory performance may serve as a pathway of which xerostomia affects quality of life. Providing early oral function intervention may be a valuable and actionable target for older adults to maintain their quality of life. Our results further suggest that checkup and screening for oral dysfunction is essential to prevent or delay the onset of complications.
