Objective: To evaluate the reliability, quality and infodemiological profile of online in-formation on antibiotic use in periodontal disease treatment in Turkiye. Materials and Methods: Six Turkish search terms related to periodontal antibiotics were queried in Google and Yandex in March 2026. After deduplication and eligibility scree-ning, 116 webpages were analysed. Reliability was assessed using Journal of the American Medical Association (JAMA) benchmarks, information quality using DISCERN and Global Quality Scale (GQS), and clinical alignment using a periodontal antibiotic stewardship check-list based on contemporary periodontal guidance.

The median JAMA score was 1.0 (IQR: 1.0-2.0), with attribution present in 19.0% and currency in 28.4%. Professional/university websites had hig-her DISCERN scores than private clinic websites (52.0 vs 36.0; p
