The Influence of Dynamic Occlusal Interferences on Probing Depth and Attachment Level: Results of the Study of Health in Pomerania (SHIP)

Background: The purpose of this study was to investigate potential associations between dynamic occlusal interferences and signs of periodontal disease in posterior teeth based on dental and medical measurements obtained from a population‐based sample in the cross‐sectional epidemiological study entitled, “Study of Health in Pomerania” (SHIP). Methods: Medical history and dental and sociodemographic parameters of 2,980 representatively selected dentate subjects, 20 to 79 years of age, were collected. The analysis was performed on posterior teeth only using a mixed linear model that considers the clustered structure of the data. The model also was adjusted with respect to known risk factors for periodontal disease. Results: The presence of non‐working side contacts only was significantly related to probing depth (P
