Occurrence of Bacterial Flora in Oral Infections of Diabetic and Non- Diabetic Patients

Diabetes mellitus is a chronic disease with serious health consequences. The association between diabetes and periodontal disease is well documented. However, the progression and healing of endodontic infections in diabetic patients has not been adequately studied. Dental lesions are emerging as a significant problem in the diabetic patients because of the improving health conditions. The purpose of the study was carried out to compare the bacterial flora from dental caries periodontitis and gingivitis in diabetic and non-diabetic patients. Specimens of dental lesions (dental caries, periodontitis and gingivitis) were collected from 100 patients in aseptic conditions, avoiding oral saprophytic contamination. The samples were cultured and incubated under aerobic and anaerobic conditions, followed by bacteriological identification. Out of 100, there are 62 diabetic and 38 non-diabetic patients. A total of 82 strains were isolated from diabetic and 60 strains were isolated from non-diabetic patients. The isolated flora in Diabetic patient/Non-diabetic patient ratio was high in Periodontitis (92.64%) as compared to gingivitis (1.23%) and dental caries (0.71%). The study demonstrates that the higher isolates were screened out from diabetic patients as compare to non-diabetic and also the study revealed that the periodontitis is higher in diabetic patients where as dental caries and gingivitis were higher in non-diabetic patients.
