Objectives:To investigate periodontitis as a risk factor for incident type 2 diabetes mellitus (T2DM) in a group of men aged 58-72 years.

Methods:1331 dentate, diabetes-free males in Northern Ireland underwent a detailed periodontal examination during [2001][2002][2003]. Follow-up was by bi-annual questionnaire and for those reporting diabetes their general medical practitioner was contacted to validate diabetes type, treatment and diagnosis date. Cox's proportional hazard models were used to estimate the effect of periodontitis on incident diabetes. Multivariable analysis included adjustment for various known confounders.
Results:The mean age of the men was 63.7 (SD 3.0) years. There were 80 cases (6.0%) of incident T2DM. Follow-up was for a median period of 7.8 years ). After adjusting for confounding variables, the hazard ratio (HR) for incident T2DM in men with moderate / severe periodontitis versus those with no / mild periodontitis was 1.69 (95% CI 1.06-2.69), p=0.03.
Conclusion:There was evidence in this homogenous group of dentate men, that those with moderate to severe periodontitis had a significantly increased risk of incident T2DM.
Clinical Relevance
Scientific rational for the study:Evidence supporting the role of chronic periodontitis as a putative risk factor for the development of type 2 diabetes mellitus (T2DM) is currently limited.
Principal findings:
Accepted ArticleThis article is protected by copyright. All rights reserved.This study showed that in a group of 58-72 year-old Caucasian dentate men in Northern Ireland, baseline moderate to severe periodontitis was an independent risk predictor for the development of T2DM. This relationship was independent of known confounders.
Practical implications:Dentists should be aware of the potential systemic health implications of patients presenting with moderate to severe periodontitis. Patients who present with obvious risk factors for T2DM and signs of periodontitis should be informed about their risk for developing T2DM.
