Abstract

Objectives: The aim of this study was to investigate whether periodontal condition is associated with the development of impaired glucose tolerance (IGT).

Material And Methods: This study was based on a subpopulation of a cohort of persons born in 1935 and living in Oulu, Finland, on October 1, 1990. The participants were normoglycemic (no previously diagnosed diabetes mellitus and a 2-h oral glucose tolerance test [OGTT] blood glucose < 7.8 mmol/L) in the baseline examinations (1990-1992) and had fasting blood glucose < 7.0 mmol/L in the follow-up examinations (2007-2008) (n = 225). The outcome was IGT on follow-up, measured by a blood glucose level of ≥ 7.8 mmol/L after OGTT. The exposure was the periodontal condition at baseline categorized into four groups: 0, 1-6, ≥ 7 sites with deepened (≥ 4 mm) periodontal pockets, and edentulousness.

Results: A total of 23% of the participants developed IGT. The adjusted incidence rate ratios with 95% confidence intervals (CI) for dentate participants with 1-6 sites and ≥ 7 sites with deepened periodontal pockets, and edentate participants (reference category dentate participants without deepened periodontal pockets) were 1.5 (95% CI, 0.6-4.0), 1.8 (95% CI, 0.7-4.4), and 1.6 (95% CI, 0.6-4.0), respectively.

Conclusions: Poor periodontal condition may predispose individuals to IGT; however, further studies on this matter are warranted.
