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

Abstract

Abstract Objective The aim of the present study is to compare and assess the risk of periodontitis due to the presence of four putative periodontopathic bacteria viz., Eikenella corrodens, Campylobacter rectus, Prevotella intermedia and Prevotella nigrescens. To fulfil the above objective, polymerase Chain reaction using the primers targeting 16S rRNA gene of the bacterial species was performed with the subgingival plaque collected from the permanent first molars of type 1 diabetic children and age matched healthy children. Results 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.
