Background: Knowledge of the wide spectrum of the oral markers of diabetes is imperative as one frequently encounters individuals with undetected, untreated or poorly controlled diabetes.
Objectives: The objective was to study the oral manifestations in type 2 diabetes mellitus (DM) and to establish an association between oral manifestations and associated microvascular and macrovascular complications.
Materials and methods: 50 cases of DM were selected who had oral complications. The control group comprised 50 age- and sex-matched diabetic patients without any oral complications.
Results: Oral manifestations in DM included periodontal disease in 34%, oral candidiasis in 24%, tooth loss in 24%, oral mucosal ulcers in 22%, taste impairment in 20%, xerostomia and salivary gland hypofunction in 14%, dental caries in 24%, and burning mouth sensation in 10% cases. Fasting [(FBG) (P = 0.003)] and postprandial blood glucose [(PPBG) (P = 0.0003)] levels were significantly higher among cases. The P values for neuropathy, retinopathy, nephropathy, cardiovascular disease, dyslipidemia, and sepsis were 0.0156, 0.0241, 0.68, 0.4047, 0.0278, and 0.3149, respectively, which were significant for neuropathy, retinopathy, and dyslipidemia.
Conclusions: Several oral complications are seen among diabetics. Association of oral markers in DM and microvascular complications suggests that there is a significant association between the two.
