Colonization by Candida is related to wearing a denture. How denture type, status, and maintenance play a role in determining Candida colonization remains unknown. This work evaluated removable denture status in an elderly population and explored the association between denture-related factors and oral Candida colonization as determined by systemic and local factors.Socio-demographic, general health, and behavioral data and oral factors were registered by means of a questionnaire. Oral, dental, and denture-related factors were assessed by clinical examination, and yeasts were isolated from oral and denture specimens. Multiple logistic regression analysis was used to explore the relative relevance of risk factors.Overall, 52.4% of subjects used complete dentures in both lower and upper arches, and 90% of the prostheses were in good condition. Denture plaque index was high in most cases, and 75% of subjects had yeasts in their oral cavities. Oral Candida colonization was significantly associated with low saliva pH, sugar consumption, and the fault of a denture component; however, only sugar consumption was found to be an independent factor related with oral Candida colonization, showing an odds ratio of 3.04 in a multiple logistic regression model.Elderly people in this study used a complete denture in good condition, with a median age of 15 years. Daily or weekly sugar consumption was found to be highly associated with oral colonization by Candida. |
