A prospective study on oral microbial flora and related variables in dentate dependent elderly residents.

Objective: Oral microorganisms and related variables were followed over a 1-year period in dentate dependent elderly.

Background: For nursing personnel, oral hygiene for the dependent elderly is demanding. It requires good knowledge of how to carry out preventive oral health measures and to judge when help is needed. Previous studies indicate low levels of knowledge, which might be reflected in the oral health of dentate residents.

Material And Methods: Twenty-one subjects participated at baseline and 14 one year later. Microbial samples were analysed using cultivation technique. The labial minor gland secretion rate was measured using the Periotron(®) method, and oral clinical data were registered.

Results: Low labial mucosal flow rates were seen for 95% of the participants. At baseline, visibly thick plaque was seen in 48% and 1 year later in 57%. Both frequency and number of bacteria associated with caries and frequency of microorganisms associated with oral soft tissue infections were high. One year later, a decrease in bacteria associated with good oral health and a tendency to an increase in aciduric microorganisms were seen.

Conclusion: Poor oral health, tending to further deteriorate over time, advocates regular professional supplementary support when elderly dentate dependent residents need assistance with their oral care.
