Objectives: To evaluate the eff ect of strict glycemic control on pocket depth (PD), bleeding on probing (BOP), fasting blood sugar (FBS), C reactive protein (CRP), and HbA1c.Methods and materials: This quasi-experimental design study was conducted from March to September 2021 taking 32 cases (A) and equal controls (B) with non-insulin uncontrolled diabetes (HbA1c more than 8, whereas the eff ect of strict glycemic control on clinical periodontitis was carried out. Pocket Depth (PD), bleeding on probing (BOP), fasting blood sugar (FBS), C reactive protein (CRP), and HbA1c levels were assessed before and after the intervention.Results: Most of the variables HbA1c (p=0.03), CRP (p=0.007), PD (p=0.006), and BOP (p=0.023) showed improvement showing a better glycemic control in the post-intervention stage; particularly for patients recruited in Group A. HbA1c levels at 3 months post-intervention showed significant reduction (p=0.03) to 8.1 ± 1.7 in Group A in comparison to 9.9 ± 2.3 in the pre-intervention stage with a mean difference of -1.8 showing improvement in the glycemic control. PD (mm) for Group A was reduced from 2.4 ± 0.5 mm to 2.2 ± 0.5. Whereas the PD ≥ 4mm (%) also showed a signifi cant reduction from 27.9 ± 28.4 in the pre-intervention to 19.4 ± 27.0 in the post-intervention stage for Group A. Group B also showed reduction but this was more prominent in group A. Bleeding on Probing (%) in group A was also signifi cantly reduced from 29.4 ± 21.4 in pre-intervention stage to 23.1 ± 23.2 in the post-intervention stage.Conclusion: The present study concludes that strict glycemic control (group A) has a role in clinically correcting/improving periodontitis in non-insulin dependent diabetic patients. It can be further concluded that periodontal treatment has a role in the improvement of glycemic control in type 2 diabetic patients at 3 months.
