“…Holm-Pedersen et al followed a cohort of 573 70-year-old Danish non-disabled elders over an observation period of 21 years and reported that 'being edentulous or having 1-9 teeth was associated with onset of disability at age 75 and 80 years' and that 'persons being edentulous at age 70 were significantly higher at risk of mortality 21 years later (Hazard ratio 1.26, 95% CI 1.03-1.55)' 68 . Other authors confirmed these findings with a shorter observation period and reported that this correlation was even more evident in men than in women 69 . They concluded that 'The number of teeth was a significant predictor of mortality independent of health factors, socio-economic status and lifestyle'.…”

Despite progress in dentistry, tooth loss in old age is still a reality, even more so in long-term-care residents. However, recent trends indicate that natural teeth are lost later in life. Functional decline and age-related pathologies have to be considered in oral health care for this vulnerable population. Retaining and restoring teeth and oral function in elders is important. Tooth loss significantly impairs masticatory performance, which cannot be fully restored by prosthodontic means. Hence an unconscious change in food intake occurs, often involving malnutrition and withdrawal from common meals. Poor oral appearance and bad breath may further impede social activities. Although a chewing activity may be beneficial for cognitive function, natural teeth can present a considerable risk for fragile elders, in whom aspiration of biofilm can lead to pneumonia and death. The presence of natural teeth is also correlated with higher life expectancy, but socio-economic confounding factors have to be considered. When evaluating oral health in the elderly population, standards and priorities for reporting oral health outcome measures have to be defined. Anatomical indicators such as the number of natural teeth or the presence of prostheses might be one option for reporting. However, functional indicators such as masticatory performance and patient-centred outcome measures may be more relevant. In conclusion, there is an overwhelming body of evidence that maintaining a healthy natural dentition in old age is beneficial from a structural, functional and psycho-social point of view.

“…38 The important relationship between the number of remaining teeth and mortality, irrespective of medical, social and economic factors, was determined by observing 4 cohorts of over 1,800 Swedes aged over 70 years. 39 The findings regarding tooth loss as an independent weak risk factor for stroke was made on the basis of a survey of more than 13,000 Americans aged over 60 years. 40 In young seniors in Wrocław, no meaningful relationship was found between body mass expressed by BMI index and number of teeth.…”

“…Tooth loss is related to subclinical atherosclerosis in men but not in women (Desvarieux et al, 2004). The number of teeth also seems to be a predictor of mortality independent of health factors and socioeconomic status but with clear-cut sex differences (Osterberg et al, 2008). IRR, incidence rate ratio; CI, confidence interval.…”

Sex-specific differences in the incidence of periodontitis and tooth loss may be related to different phenotypes of obesity and their associations with low-grade inflammation. The aim of this study was to evaluate associations of adiposity and lowgrade inflammation with tooth loss in men and women. Follow-up data of 2,714 participants from the cohort of Study of Health in Pomerania were analyzed for anthropometric measures, periodontitis, tooth loss, C-reactive protein (CRP), and interleukin 6. Regression analyses were used to estimate the effect of obesity on tooth loss within sex strata. During the follow-up period, men lost more teeth in relation to their obesity status than did women. In contrast, there was a steeper increase in CRP levels across obesity levels in women as compared to men. Incidence rate ratio (IRR) of tooth loss associated with elevated CRP, however, was higher in men (IRR = 1.50; 95% confidence interval [CI]: 1.27, 1.77) than women (IRR = 1.18; 95% CI: 1.02, 1.37). Negative binomial regression with number of lost teeth as outcome revealed dose-response dependencies on body mass index and waist-to-hip ratio. Adjusted for covariates, the IRR of tooth loss associated with the third tertile of waist-to-hip ratio was 1.37 (95% CI: 1.04, 1.80) and 1.53 (95% CI: 1.14, 2.05) in men and women, respectively. Tooth loss related to CRP cutoff of 2 mg/L was significant in men (IRR = 1.33; 95% CI: 1.07, 1.66; p = .006) but not in women (IRR = 0.92; 95% CI: 0.73, 1.17; p = .689). This study suggests that both adiposity and subclinical inflammation affect tooth loss, with distinct differences between men and women. Obesity as a risk factor of tooth loss is particularly related to CRP in men but not in women.
