Abstract
The purpose of the present study was to examine the relation between oral hygiene habits, denture plaque, presence of yeasts and stomatitis in institutionalised elderly. A sample of 201 residents, 48–99 yr of age (mean age 82 yr), was selected from four different institutions in Lothian, Scotland. Clinical recordings were carried out under standardised circumstances using well recognised indices. Information about oral hygiene habits was obtained through structured interviews conducted immediately before the clinical examination. A multivariate analysis, principal component, was carried out on the correlated five maxillary denture plaque scores and two components, accounting for 74% and 12% of the variation, were identified. Using these two independent variables, an analysis of variance was carried out testing for significance between the four effects: soaking habits, brushing habits, denture stomatitis and growth of yeats in the palate together with their interactions. The analysis showed significiant relation between maxillary denture plaqre, soaking habits and the presence of denture stomatitis. The was no relation between denture plaque and brushing habits or between denture plaque and growth of yeasts.
