There have been few prospective studies on the relationship between oral health conditions and the development of metabolic syndrome (MetS). This prospective cohort study was performed at a Japanese company over one year. Routine medical health examinations, oral health examinations, and a questionnaire pertaining to education, job type, and health behaviors was administered. Participants aged ≥35 years who had no MetS components at baseline were re-examined after one year. Modified Poisson regression analyses were performed to calculate the relative risks (RRs) associated with oral health variables, including periodontitis, decayed and missing teeth, and decayed, missing, and filled teeth (DMFT) in relation to the development of MetS. Of 152 eligible participants, 136 were re-examined after one year; 30 exhibited one or more newly developed MetS components upon re-examination. Decayed teeth at baseline were significantly associated with development of at least one MetS component (adjusted RR 3.25, 95% confidence interval 1.59-6.63). There were no associations between periodontitis, missing teeth, or DMFT and the development of MetS. The association between decayed teeth and MetS was independent of other risk factors, including age and body mass index; therefore, decayed teeth may be associated with the development of MetS.
