Intraoral candida in Thai diabetes patients

The purpose of this study was to determine the oral candidal prevalence and identify the candidal species in fifty four diabetes and sixty two healthy, non smoking and non denture wearing subjects. The modified imprint culture technique was used for candidal isolation. It was found that the prevalence of oral candida was significantly higher in diabetics (P < 0.00001) with the relative risk of positive culture at 3.674 (95% CI = 1.998-6.757). The most frequent candidal species in diabetics were C. albicans (81.3%) followed by C. glabrata (9.4%), C. tropicalis (3.1%) and C. rugosa (3.1%). There were two species of C. tropicalis and C. rugosa in one subject (3.1%). The candidal species in healthy subjects was only C. albicans (100%).
