Frequency of putative periodontal pathogens among type 1 diabetes mellitus: a case-control study.

The prevalence of periodontal pathogens in diabetic and healthy children was 6% and 16% for E. corrodens, 18% and 36% for C. rectus, 2% and 2% for P. intermedia, 4% and 0%, for P. nigrescens respectively. Statistically, significant difference was not observed for the prevalence of all the four periodontal pathogens between type 1 diabetic and healthy children (P = 1.00). The results of the present study thus reveal a negative correlation of type I diabetes to periodontitis in association to Eikenella corrodens, Campylobacter rectus, Prevotella intermedia and Prevotella nigrescens.
