Background and Objective Chronic diseases have progressively increased worldwide, impacting all areas and socioeconomic groups. Periodontal disease is an increasing global concern and contains risk factors similar to other chronic illnesses. The main risk factor for periodontitis is smoking. Smoking not only hastens periodontal disease but also complicates periodontal therapy. Serum glycosylated hemoglobin levels, which are derived from the average life span of an erythrocyte, are a good indicator of glycemic management during the preceding one to three months. This study was undertaken to assess the association between tobacco smoking and periodontal disease by evaluating plaque score, gingival score, extent and severity index (ESI), and glycemic status by estimating serum HbA1c in cigarette smoker patients compared to non-smokers. Methods The study was conducted with 40 patients in the age range of 20–40 years. Patients were divided into two groups: non-smokers (Group I) and cigarette smokers (Group II). Periodontal clinical parameters such as the plaque index (PI), gingival index (GI), and ESI were recorded during the oral cavity examination. The biochemical marker, serum glycosylated hemoglobin, was measured in both groups. All parameters were measured at baseline and three months after periodontal therapy. The statistical tests used were the paired t-test , and Chi-square test for comparison between both groups. Results The mean difference of PI of non-smokers was 0.33 ± 0.30, and smokers were 0.52 ± 0.32, which was statistically significant. The mean difference of GI of non-smokers was 0.34 ± 0.19 and smokers 0.36 ± 0.303, which was statistically significant. The mean difference of extent in non-smokers was 5.33 ± 1.59, 5.52 ± 2.43, and smokers were 0.18 ± 0.17. The mean difference in severity in non-smokers was 0.18 ± 0.17, and smokers were 0.31 ± 0.25, which was statistically significant. The mean difference of HbA1c in non-smokers and smokers was 0.43 ± 0.277 and 0.415 ± 0.230, which shows a higher mean difference in non-smokers, which was statistically non-significant. Conclusion and Global Health Implications This study concluded that each of Group I and Group II showed substantial improvements in all clinical periodontal variables, which include plaque index (PI), gingival index (GI), extent and severity index (ESI), and biochemical marker serum glycosylated hemoglobin. Controlling inflammation with SRP can improve insulin resistance, lower glucose levels, and prevent non-enzymatic glycation of hemoglobin.
