Relationship between oral hygiene and fungal growth in patients: users of an acrylic denture without signs of inflammatory process.

OBJECTIVES: To answer to the following questions: is there any relationship between oral hygiene and the growth of yeast in patients without mucosal inflammation; and is there a need for mycological examination patients without mucosal inflammation? BACKGROUND: Patients with candidiasis may report varied symptoms, but such infections are most often asymptomatic. In addition to its high incidence in denture users (60%-100%), there is a concern that Candida species from the oral cavity may colonize the upper gastrointestinal tract and lead to septicemia, which has a 40%-79% mortality rate and can require a prolonged hospital stay. It is thus important for all physicians to be aware of the risk factors, diagnosis, and treatment of oral candidiasis in older patients. METHODS: A retrospective study was carried out on a group of patients who had undergone mycological examination and assessment of the intensity of yeast growth, and oral hygiene. RESULTS: Ninety-one denture wearers who lacked signs of clinical inflammation were included in the study. The growth of Candida albicans was as follows: 14 patients had up to 20 colonies; 19 patients had over 20 colonies. Ten percent of patients with good oral hygiene proved to have more than 20 yeast colonies. 5% of patients with bad oral hygiene had more than 20 colonies. CONCLUSIONS: There was no relationship found between hygiene and the growth rate of fungal microorganisms. In patients without clinical symptoms of stomatitis, mycological examination should be considered.
