“…Third, tooth loss and denture use are closely related, but the potential interaction between tooth loss and denture use, in relation to mortality, have not been comprehensively evaluated. Forth, many important confounders, like economic status, were not adjusted in most previous studies [5][6][7][8][9][10][11][12][13]. Fifth, previous studies evaluating denture use and mortality showed inconsistent results [13,21].…”

Background: The associations between the number of natural teeth/denture use and all-cause mortality remain unclear due to lake of investigation for the potential interaction between tooth loss and denture use and for the potential changes in these exposures over time in older adults. We undertake this study to evaluate the associations of the number of natural teeth and/or denture use with mortality in Chinese elderly. Methods: This is a prospective cohort study of 36,283 older adults (median age: 90). The number of natural teeth and denture use were collected with structured questionnaire. We evaluated hazard ratios (HRs) and confidence intervals (CIs) using a Cox proportional hazards model adjusting for demographic factors, education, income, lifestyle factors, and comorbidities. Results: We documented 25,857 deaths during 145,947 person-years of observation. Compared to those with 20+ teeth, tooth loss was associated with a gradual increase in mortality, with an adjusted HR of 1.14 (95% CI, 1.06 to 1.23) for those with 10-19 teeth, 1.23 (95% CI, 1.15 to 1.31) for those with 1-9 teeth, and 1.35 (95% CI, 1.26 to 1.44) for those without natural teeth. Denture use was associated with lower risk of mortality (adjusted HR 0.81; 95% CI, 0.77 to 0.84). Subgroup analyses indicated that the benefit of denture use was greater in men than in women (P = 0.02) and tended to decrease with age (P < 0.001). The effects of denture use did not differ among various degrees of tooth loss (P = 0.17). Conclusions: Tooth loss was associated with an increased risk of mortality in older adults. Denture use provided a protective effect against death for all degrees of tooth loss however, this effect appeared to be modified by sex and age.

“…A number of prospective studies have found an association between tooth loss and all-cause mortality, cardiovascular and cancer mortality [5][6][7][8][9][10][11]. Wearing dentures may reduce the mortality in older adults [7,12,13].…”

“…Tooth loss can also impact facial appearance and therefore affect self‐esteem and socialization . Other systemic conditions, such as cognitive decline and peripheral arterial disease, as well as overall mortality, have been linked to tooth loss. Financial limitations have also been linked to reduced oral healthcare utilization among older adults in multiple countries, and increased oral health insurance coverage is associated with higher use of oral healthcare services …”

Objectives:Oral health plays an important role in the general well-being of older adults, yet older adults experience unique barriers to dental care. In the United States, almost two-thirds of older adults are dentally uninsured -a reflection of the exclusion of dental benefits from Medicare. The aim of this study was to investigate potential predictors of having a dentist among older adults receiving services funded through the Iowa Department on Aging (IDA).Methods: This was a cross-sectional analysis on a convenience sample (n = 2692) of adults age 65+ who completed a required survey to determine eligibility to receive services from the IDA. Data from questionnaires completed between March and December 2017 were used to generate multivariable logistic regression models that identified predictors of having a dentist. The dependent variable, having a dentist, was gathered by self-report in the survey. Explanatory variables eligible for inclusion in the models included demographic and geographic factors, indicators of access to dental care, and factors related to activities of daily living. Results:Fewer than half (46.2%) of the respondents reported having a dentist. In the final regression model, individuals with dental insurance were more than twice as likely to have a dentist than those without insurance. Conversely, individuals with a tooth/mouth problem and who need help with housekeeping and with transportation were significantly less likely to have a dentist than their counterparts. Conclusions:These results align with known insurance-related barriers and identify certain activities of daily living that might influence older adults' ability to access care. The finding that individuals with oral health problems were less likely to have a dentist underscores the need to reduce barriers to care for this population.

“…Several reviews have reported tooth loss and complete edentulism to be associated with multiple systematic comorbid conditions such as obesity, COPD‐related events, pneumonia, head and neck cancer, and cognitive decline as well as with an increased risk of mortality . Gupta and Koka conducted a systematic review to examine the association between tooth count and all types of mortality and found an overall trend towards a relationship between the number of teeth and mortality, with a lower tooth count being associated with higher all‐cause and cause‐specific mortality . Furthermore, Osterberg et al showed tooth loss to be an independent risk factor for increased mortality in 70‐year‐old patients, irrespective of socioeconomic or lifestyle factors .…”
