Summary Studies concerning the role of denture status on in temporomandibular disorders ( TMD ) are scarce. The aim of this study was to evaluate the association of tooth loss and denture status with clinical findings of TMD . The data were obtained from 6316 subjects aged ≥30 years from the F innish H ealth 2000 S urvey. The associations between clinically assessed TMD findings and number of teeth, wearing of removable dentures, need for denture repair and age of the dentures were analysed by means of chi‐square test and logistic regression. Among women after adjusting for age, having fewer teeth or wearing complete dentures associated with restricted maximum interincisal distance and pain on palpation of the temporomandibular joints ( TMJ ) and masticatory muscles. After adding education level and depression in the model, the associations between TMJ pain and explanatory variables were weakened. Among men, having a higher number of teeth associated with occurence of TMJ crepitation. Subjective need for repair of dentures and having a denture aged ≥5 years associated with pain on palpation in masticatory muscles among women. Among men, both the objective and subjective need for denture repair and having at least one denture aged ≥5 years or been repaired during the past 5 years associated negatively with the presence of TMJ crepitation. It can be concluded that edentulousness, wearing of complete dentures and poor condition of dentures associate with pain‐related TMD findings among women. Psychosocial factors have a modifying effect on these associations.
