AIM: We aimed to investigate associations between malocclusions and periodontal disease by comparing it to that of smoking in subjects recruited from the population-based cross-sectional study "Study of Health in Pomerania". MATERIALS AND METHODS: Sagittal intermaxillary relationship, variables of malocclusion, and socio-demographic parameters of 1202 dentate subjects, 20 to 39 years of age, were selected. Probing depth (PD) and attachment loss (AL) were assessed at four sites by tooth in a half mouth design. Analyses were performed with multilevel models on subject, jaw, and tooth level. RESULTS: Distal occlusion determined in the canine region, ectopic position of canines, anterior spacing, deep anterior overbite, and increased sagittal overjet were associated with AL (p-value < 0.05). Associations between malocclusions and PD: deep anterior overbite (odds ratio (OR) = 1.40 for gingival contact, 95% CI: 1.08-1.82; p-value = 0.0101) and anterior crossbite (OR = 1.75, 95% CI: 1.29-2.38; p-value = 0.0003). Regarding crowding, only severe anterior crowding was compatible with a moderate to large association with PD (OR = 1.93, 95% CI: 0.89-4.20). Compared to smoking, the overall effect of malocclusions was about one half for AL and one third for PD. CONCLUSION: Malocclusions or morphologic parameters were associated with periodontal disease.
