A cross-sectional comparative study involved 180 adolescents aged 12–18 years, divided into groups: patients with compensated T1DM (n=80), conditionally healthy individuals (n=80), and adolescents with periodontitis associated with poor oral hygiene (n=20). The methodology included clinical assessment of periodontal indices (BOP, PPD, CAL), quantitative determination of key periodontopathogenic bacteria (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola) using real-time PCR, and analysis of biochemical markers (interleukin-1β, matrix metalloproteinase-8, osteoprotegerin) in oral fluid. The results revealed that adolescents with T1DM, compared to their healthy peers, had a 2.5 times higher bleeding index (BOP: 25.0% vs. 10.5%, p UR - https://tsdp.net/article/clinical-and-laboratory-characteristics-of-periodontal-disease-in-adolescents-with-type-1-diabetes-j7y0o7diwuanoqt ER -
