Background: Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic disorder associated with several systemic complications, including periodontal disease. Periodontitis is considered the sixth complication of diabetes mellitus and is characterized by chronic inflammation and destruction of supporting periodontal tissues. Poor glycemic control has been reported to increase the severity and progression of periodontal disease, while periodontal inflammation may adversely influence glycemic status through systemic inflammatory mechanisms. Objectives: To assess periodontal status among patients with Type 2 Diabetes Mellitus and to determine the association between severity of periodontitis and glycemic status. Methods: A hospital-based cross-sectional observational study was conducted among 80 patients with Type 2 Diabetes Mellitus attending the Department of Dentistry at K H Patil Institute of Medical Sciences, Gadag. Data regarding demographic details, duration of diabetes, oral hygiene practices, and systemic factors were collected using a structured proforma. Periodontal examination included assessment of Gingival Index, Plaque Index, Bleeding on Probing, Probing Pocket Depth, and Clinical Attachment Loss. Glycemic status was assessed using HbA1c values. Chi-square test, One-way ANOVA, and Spearman correlation analysis were applied. A p value <0.05 was considered statistically significant. Results: The mean age of participants was 53.3 ± 10.8 years. Severe periodontitis was observed in 38.7% of participants, while 47.4% exhibited poor glycemic control. Participants with poor glycemic control demonstrated significantly higher Gingival Index, Plaque Index, Probing Pocket Depth, Clinical Attachment Loss, and Full Mouth Bleeding Score compared to those with controlled diabetes (p<0.001). A statistically significant association was observed between periodontitis severity and glycemic status (p<0.001). HbA1c levels showed significant positive correlation with periodontal parameters, particularly Full Mouth Bleeding Score (r=0.664) and Gingival Index (r=0.634). Conclusion: The study demonstrated a significant association between poor glycemic control and worsening periodontal status among patients with Type 2 Diabetes Mellitus. Routine periodontal evaluation and integrated oral healthcare may play an important role in improving diabetic management and preventing periodontal destruction.
