<![CDATA[Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia and is associated with an increased risk of periodontal disease and greater periodontal tissue destruction. However, the relationship between blood glucose levels and the severity of periodontitis among patients with diabetes mellitus requires further evaluation in specific clinical settings. This study aimed to determine the association between blood glucose levels and periodontitis severity among patients with diabetes mellitus attending the Periodontic Polyclinic of Dr. Ramelan Naval Central Hospital, Surabaya. An analytical observational study with a cross-sectional design was conducted among 30 patients with diabetes mellitus selected using a total sampling approach. Blood glucose data were obtained from fasting or random blood glucose records documented within the preceding three months, while periodontal status was assessed clinically using the Community Periodontal Index of Treatment Needs (CPITN). Descriptive statistics were used to characterize the participants, and the association between blood glucose levels and periodontitis severity was analyzed using the Chi-square test with a significance level of 0.05. Among the participants, 17 (57%) had uncontrolled blood glucose levels, whereas 13 (43%) had controlled levels. Moderate periodontitis was the most frequently observed condition, affecting 14 participants (47%), followed by severe periodontitis in 9 (30%) and mild periodontitis in 7 (23%). The Chi-square analysis demonstrated a statistically significant association between blood glucose levels and periodontitis severity (p < 0.001). Patients with uncontrolled blood glucose levels were more frequently observed in the moderate-to-severe periodontitis categories. In conclusion, blood glucose control was significantly associated with periodontitis severity in patients with diabetes mellitus. These findings support the importance of integrating glycemic monitoring with routine periodontal assessment as part of comprehensive diabetes management.]]>
