Hirotomi T, Yoshihara A, Ogawa H, Miyazaki H. Tooth‐related risk factors for periodontal disease in community‐dwelling elderly people. J Clin Periodontol 2010; 37: 494–500. doi: 10.1111/j.1600‐051X.2010.01565.x. Abstract Objective: While most previous epidemiological studies have focused on subject‐level risk factors for periodontal destruction, tooth‐related factors have not been fully explored. The purpose of this study was to evaluate both tooth‐related and subject‐related factors affecting periodontal disease progression using a two‐level multilevel model. Material and Methods: A longitudinal survey over a period of 10 years was carried out on 286 community‐dwelling elderly subjects aged 70 years at baseline. Clinical attachment level (CAL) was measured at six sites per tooth on all teeth present and periodontal disease progression was defined as CAL3 mm. Results: Periodontal disease progression was found in 79% of the subjects and most frequently in maxillary molars. Multilevel logistic regressions revealed that subjects wearing removable dentures were significantly at risk for periodontal disease progression. Abutment teeth for removable/fixed dentures were also significantly more likely to suffer periodontal breakdown. Furthermore, the following tooth‐related variables were found to be possible risk factors for periodontal disease progression: maxillary and multirooted teeth. Conclusion: Multirooted teeth and abutments for a fixed denture were possible risk factors for periodontal disease progression.
