A preliminary group matched comparison study of periodontal status was conducted among Indian participants who had type 1 diabetes mellitus (T1DM) and non-diabetic controls. The mean number of bleeding sites, gigival index score, number of periodontal pocket's and number of clinical loss attachment sites were all significantly higher in cases compared to controls. This study provides evidence that people with type I diabetes mellitus have a higher risk of gingival and periodontal disease.
