Abstract
BackgroundThere is no data available on the prevalence of oral mucosal lesion and candida infection among DM patients which necessitate conducting a local or nation-wide study to assess the oral mucosa lesions and candida prevalent in diabetic patients in Riyadh, Saudi Arabia. ObjectivesThe objective of the present study was to characterize oral mucosa lesions, and the prevalence of yeasts in diabetic patients and their association with the risk factors in comparison with a group of non-diabetic controls. MethodsStudy design: A cross-sectional comparative study was conducted assuming 50% of the diabetic patients have oral lesions compared to nondiabetic patients and a power of 80% with 5% level of significance, the minimum required sample size was estimated to be 115 in each group.The buccal swabs were collected to isolate Candida species from the individual patient with a current and former history of diabetes. The laboratory findings were collected and the clinical examination of the oral mucosa was processed at the department of microbiology. ResultsThe results inferred a significant presence of oral mucosa alterations in the diabetic group. A majority of the patients were suffering from type 2 diabetes for the past 10 years. C. albicans was the predominant yeast, followed by. C. tropicalis and C. krusei nonalbicans species that were most frequently isolated. Diabetes and smoking habit were the two risk factors for oral mucosa alterations. ConclusionsThe study found a significant presence of oral mucosa alterations in the diabetic group and the fungal infection tended to be more in the diabetic group with a high incidence of C. albicans. The presence of diabetes and smoking habit were two risk factors identified as significant for oral mucosa alterations. The significant variation in education level in groups indicates that education would help to enhance the prognosis in diabetic patients and healthcare behavior.
