Abstract
Objectives: To study the prevalence, association and correlation of periodontal disease in patients with type 2 diabetes mellitus (T2DM).
Methods: One hundred consecutive patients with T2DM and an equal number of age- and sex-matched non-diabetic controls were studied. Diabetes was diagnosed as per American Diabetic Association criteria. All subjects were evaluated for presence and severity of periodontal disease activity clinically and radiologically.
Results: Prevalence of periodontitis in cases and controls was not significantly different as per clinical attachment loss (CAL) (97% versus 90%, p=0.085) and radiological assessment (97% versus 89%, p=0.052) but prevalence of severe periodontitis was higher among cases (p=0.001). Gingival index and periodontal pocket depth were significantly higher among cases (p=0.001each). Diabetes had a significant association with severity of CAL (p=0.001) and radiological damage (p=0.001) but not with CAL (p=0.085) and radiological damage (p=0.052). Severity of periodontitis had a significant association with glycosylated haemoglobin (HbA1c) level (p=0.001), fasting blood sugar (FBS) (p=0.001) and post-prandial blood sugar (PPBS) (p=0.011) while radiological severity of periodontitis had a significant association with HbA1c (p=0.001) and FBS (p=0.01). CAL showed a significant correlation with HbA1c (r=0.708, p=0.0001), FBS (r=0.476, p=0.001), PPBS (r=0.425, p=0.001) and random blood sugar (r=0.476, p=0.001) but not with age (r=0.061, p=0.393), and duration of diabetes (r= -0.024, p=0.811). Both CAL and radiological severity were independently associated with HbA1c (p=0.000 each),
Conclusions: Periodontitis is an important complication in T2DM. Severity of periodontitis is associated with diabetes and the related parameters, while HbA1c is independently associated with periodontitis.
Significant findings of the study
• Diabetes increases the severity of periodontitis, assessed by the clinical as well as radiological examination.
• Severity of periodontitis has significant correlation with the blood sugar and glycosylated haemoglobin levels.
What this study adds?
• Glycosylated haemoglobin is independently associated with the severity of periodontitis ascertained by clinical attachment loss and radiological examination.
