This meta\u2010analysis evaluates the efficacy of antioxidants in improving periodontal and glycemic outcomes in T2D patients with periodontitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and Methods<\/jats:title>\n                    <jats:p>A systematic literature search was conducted using PubMed, Embase, Scopus, Web of Science, and Google Scholar, covering publications from 2015 to 2025. Antioxidants tested were melatonin, propolis, lycopene, ginger, vitamin C, omega\u20103 fatty acids (O3FAs), and grape seed extract. Outcomes (clinical attachment level [CAL], probing depth [PD], gingival index [GI], HbA1c) were analyzed using random\u2010effects models (mean differences, 95% CIs).

Melatonin and propolis also reduced HbA1c (melatonin: SMD \u22122.28; propolis: SMD \u22123.83). Lycopene and ginger showed modest effects, while vitamin C and O3FAs had minimal impact.
