Objective:
Examining oral health and oral hygiene as predictors of subsequent one-year survival in the institutionalised elderly.
Design:
It was hypothesized that oral health would be related to mortality in an institutionalised geriatric population. A 12-month prospective study of 292 elderly residing in nine geriatric institutions in Granada, Spain, was thus carried out to evaluate the association between oral health and mortality. Independent samples, T-test, chi-square test and Cox regression analysis were used to analyse the data. Sixty-three participants died during the 12-month follow-up.
Results:
Mortality was increased in denture users (RR = 2.18, p= 0.007) and in people suffering severe cognitive impairment (RR = 2. 24, p= 0.003). One-year mortality was 50% in participants having both these characteristics.
Conclusions:
Oral hygiene was not significantly associated with mortality. Cognitive impairment and wearing dentures increased the risk of death. One-year mortality was 50% in cognitively impaired residents wearing dentures as opposed to 10% in patients without dentures and cognitive impairment.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
