Does periodontal inflammation affect glycosylated haemoglobin level in otherwise systemically healthy individuals? - A hospital based study.

BACKGROUND AND

OBJECTIVES

Microbial biofilm and host susceptibility play an important role in the initiation and progression of periodontitis. Periodontitis is considered the sixth complication of diabetes mellitus and a bidirectional relationship exists between diabetes and periodontitis. This cross-sectional observational study was undertaken to evaluate the glycosylated haemoglobin (HbA1c) level in chronic periodontitis.

METHODS

The study involved 100 subjects. The case group consisted of 50 subjects with chronic periodontitis and the control group consisted of 50 periodontally healthy subjects. Periodontal parameters including plaque index, oral hygiene index, modified gingival index, probing pocket depth, and clinical attachment level were measured and recorded. Systemic parameters like Body Mass Index (BMI), Waist Hip Ratio (WHR), C- Reactive Protein (CRP), Glycosylated haemoglobin (HbA1c), lipid profile, fasting blood sugar, post prandial blood sugar and serum albumin were assessed in all subjects.

RESULTS

The mean HbA1C for the case group was 6.27±1.5 and for the control was 5.36±0.4 and the difference was statistically significant (p = 0.001). The mean FBS, PPBS, LDL, WHR, CRP was statistically significant between groups (p ≤0.05). Periodontal parameters like PI, OHI, MGI, PD and CAL were significantly higher in the case group than the control group (p value ≤ 0.05). The multivariate linear regression model with the dependent variable HbA1c showed chronic periodontitis was significantly associated with HbA1c level.

CONCLUSION

In chronic periodontitis patients (otherwise systemically healthy) the presence of periodontal inflammation affected the glycosylated haemoglobin level and they were in prediabetes stage. Therefore, it is plausible that the prediabetes stage might be reduced via appropriate periodontal therapy.
