Periodontal and hematological parameters were assessed at baseline and 3\u2009months after treatment. Inter\u2010 and intra\u2010group analyses were performed using Student's <jats:italic>t<\/jats:italic>\u2010tests, Mann\u2013Whitney U tests, and the binary logistic regression models. <jats:italic>p\u2010<\/jats:italic>values of &lt;.05 were considered statistically significant.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>This study enrolled 49 patients, with 23 and 26 patients in the SRP\u2010only and SRP\u2009+\u2009antibiotics groups, respectively.

The HbA1c levels decreased in the SRP\u2010only and SRP\u2009+\u2009antibiotics groups after treatment (0.39% and 0.53%, respectively). The multivariable binary logistic regression model demonstrated that antibiotics administration and a high baseline HbA1c level were associated with a greater reduction in the HbA1c level (odds ratio\u2009=\u20094.551, 95% confidence interval: 1.012\u201320.463; odds ratio\u2009=\u20097.162, 95% confidence interval: 1.359\u201337.753, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>SRP and SRP plus systemic antibiotics were beneficial for glycemic control.
