Association of oral yeast carriage with specific host factors and altered mouth sensation.
OBJECTIVE
The aim of this study was to determine if there was a significant association between the presence of altered mouth and taste sensations with oral carriage of yeasts and to assess the factors that influence the yeast carriage.


METHODS
The oral and dental status including unstimulated (USFR) and stimulated (SSFR) whole salivary flow rates of a total of 509 subjects was recorded. Saliva specimens were collected for microbiologic examination. Multiple logistic regression analysis was performed to identify any factors that were significantly associated with the prevalence of oral yeasts.


RESULTS
Old age, clinical signs of oral dryness, denture wearing, and a reduction in USFR increased the prevalence of yeasts, whereas patient gender, levels of dentition, the sensation of dry or burning mouth, taste disorders, and SSFR were not associated with increased prevalence of oral yeasts.


CONCLUSIONS
An increased prevalence of oral yeasts was not found to relate to changes in mouth sensation alone. Other factors, most notably patient age, the wearing of dentures, clinical signs of oral dryness, and salivary flow rate under rest conditions, were, however, found to be closely associated with oral yeast carriage.
