Evaluation of adhesion to buccal epithelial cells in Candida species obtained from denture wearers after exposure to fluconazole.
The aim of this study was to assess the adhesion ability by Candida spp. obtained from denture wearer patients with and without denture stomatitis and the possible reduction in adhesion after exposure to fluconazole. Nine C. tropicalis, five C. glabrata and two C. parapsilosis obtained from the oral cavity of patients with denture stomatitis and 11 C. tropicalis, nine C. glabrata and six C. parapsilosis obtained from the oral cavity of denture wearers with normal palatal mucosa were compared for adhesion ability to buccal epithelial cells (BEC) and reduction in adhesion after exposure to fluconazole. Candida spp. obtained from denture stomatitis patients were more adherent to BEC, and there was a reduction in adhesion after exposure to fluconazole in all the species tested. Our results demonstrated that exposure to fluconazole reduces Candida spp. adherence to BEC. These results also suggest that adhesion, even in non-albicans species, could be factors that, along with predisposing conditions related to the host, determine if an individual will develop disease or remain as a healthy carrier and confirm that fluconazole has an impact in the adherence ability in Candida spp.
