[Dental occlusion and subjective temporomandibular joint symptoms in men and women. Results of the Study of Health in Pomerania (SHIP)].
Aim of the study was to determine whether associations exist in men as well as in women between occlusal factors like malocclusions or factors of functional occlusion and subjective temporomandibular joint (TMJ) symptoms, based on the population-based Study of Health in Pomerania (SHIP-0). A representative sample of 4310 men and women (response rate 68.8%) aged 20 to 81 years was examined for subjective temporomandibular joint symptoms, malocclusions (incl. normal occlusion), factors of functional occlusion and for sociodemographic parameters. Men and women were analyzed separately with multiple logistic regression analyses, adjusted for age. The results were compared to other population-based studies from an own systematic review on this subject. In men and women, none of the 48 occlusal factors under survey (malocclusions or functional occlusion) was significantly more frequently associated with the dependent variable "subjective temporomandibular joint symptoms". In contrast, the parafunction "frequent clenching" was associated more frequently and clinically relevant with TMJ symptoms in both sexes (for men, odds ratio = 4.2, prevalence 4.9%; for women OR = 2.9, prevalence 5.6%). Malocclusions and functional occlusion factors only explained a smaller part of the differences between the male and female population with and without subjective TMJ symptoms. Compared to other population-based studies only few and inconsistent associations between occlusal factors and subjective temporomandibular symptoms were ascertainable in both sexes.
