Periodontitis in older Swedish individuals fails to predict mortality.

objectivesThis study aims to assess mortality risk and its association to health aspects in dentate individuals 60 years of age and older. MATERIALS AND

methodsMedical and periodontal data from 870 dentate individuals (age range 60–96) participating in the Swedish National Study on Aging and Care in Blekinge (SNACBlekinge)with survival statistics over 6 years were studied.

resultsDuring 6 years of follow-up, 42/474 of the individuals(8.9 %), who at baseline were between age 60 and 75, and 134/396 individuals of the individuals (33.9 %), who at baseline were ≥75 years, died. Surviving dentate individuals had more teeth (mean 19.3, S.D.±7.9) than those who died (mean 15.9,S.D.±7.3; mean diff 3,3; S.E. mean diff 0.7; 95 % CI 2.0, 4.6;p=0.001). A self-reported history of high blood pressure (F=15.0, p<0.001), heart failure (F=24.5, p<0.001, observed power=0.99), older age (F=34.7, p<0.001), male gender(F=6.3, p<0.01), serum HbA1c with 6.5 % as cutoff level(F=9.3, p=0.002) were factors associated with mortality. A medical diagnosis of heart disease, diabetes, any form of cancer,or periodontitis failed to predict mortality.

conclusionsA self-reported history of angina pectoris, chronic heart failure, elevated serum HbA1c, and few remaining teeth were associated with mortality risk. A professional diagnosis of cardiovascular disease, diabetes, cancer, or periodontitis was not predictive of mortality. CLINICAL RELEVANCE: Self-health reports are important to observe in the assessment of disease and survival in older individual.
