Diabetes, a pathology that is extremly widespread, involves an alteration homeostasis in the glucose
metabolism. Periodontitis is a infectious disease resulting in irreversible destruction of the tooth attachment
apparatus. At present, periodontitis is one of the major reasons for adult tooth loss. The periodontal clinical
examination determined the following diagnosis categories: chronic gingivitis and chronic periodontitis , all of
them being modulated by the systemic disease. Aim of the study is to highlight possible correlations between
periodontal status and diabetic clinical parameters characterizing patients diagnosed with type 1 diabetes(T1D).
Material and methods This study was conducted on 62 patients. We analysed the general information of the
patients and an oral examination for establishing the parodontal diagnosis. The probing depth has been
established, number of teeth with pockets Larbert than 6mm and the plaque index Silness and Loe. Results
Significant differences were found between the IP values on children and adults but there were no significant
differences between IP on GTA and GCA or between IP on GTC and GCC. We did not find a statistically
significant correlation between HbA1c and severity of periodontal diagnosis GTC. But found a direct correlation
between HbA1c and statistically significant in periodontal diagnosis GTA. Conclusions The results obtained in
this study show a possible relationship between metabolic changes caused by periodontal T1D and, especially
in the group of adult patients
