AIMS The original Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I diagnostic algorithms have been demonstrated to be reliable. However, the Validation Project determined that the RDC/TMD Axis I validity was below the target sensitivity of ≥ 0.70 and specificity of ≥ 0.95. Consequently, these empirical results supported the(More)
The need for cross-culturally adapted oral-health specific health outcome measures is increasingly recognized in Germany. Following accepted cultural adaptation technique guidelines, we report the development of the German version of the Oral Health Impact Profile (OHIP). The original 49 items were translated using a forward-backward method. A de novo(More)
OBJECTIVE As part of the Multisite Research Diagnostic Criteria For Temporomandibular Disorders (RDC/TMD) Validation Project, comprehensive temporomandibular joint diagnostic criteria were developed for image analysis using panoramic radiography, magnetic resonance imaging (MRI), and computerized tomography (CT). STUDY DESIGN Interexaminer reliability was(More)
AIMS To develop a German-language version of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a formal translation/back-translation process, to summarize available data about their psychometric properties, and to provide new data about psychometric testing of components of the RDC/TMD. METHODS To cross-culturally adapt(More)
PURPOSE This study described oral health-related quality of life (OHRQoL) before and after treatment in patients with fixed, removable, and complete dentures. MATERIALS AND METHODS OHRQoL was measured using the German version of the Oral Health Impact Profile (OHIP-G) in a convenience sample of 107 prosthodontic patients at baseline and 1 and 6 to 12(More)
The purpose of the study was to examine whether patients' psychosocial profiles differ depending on if the location of pain is in the masticatory muscles, the temporomandibular joint, or both. Eligible participants were 491 consecutive patients examined according to the research diagnostic criteria for temporomandibular disorders (RDC/TMD). Among these a(More)
OBJECTIVES Comparing the level of impaired oral health-related quality of life (OHRQoL) in patients with a specific temporomandibular disorder (TMD) diagnosis to general population subjects unaffected by TMD to derive the unique functional and psychosocial impact due to TMD. METHODS A sample of 471 consecutive treatment seeking adult patients with at(More)
The aims of this study were, first, to report normative values for jaw movements in Caucasian children and adolescents (maximum opening, laterotrusion, and protrusion) and, second, to investigate the influence of age, gender, and temporomandibular disorders (TMD) on jaw movement capacity. The population-based study included 1,011 randomly selected German(More)
Questionnaires measuring oral health-related quality of life (OHRQoL) need reference values for their interpretation. Population-based norms for a questionnaire allow a comparison of the level of OHRQoL observed for an individual or a group of subjects with the level of that construct in the general population. The aims of this study were to establish(More)
The aim of this study was to analyze whether generalized joint hypermobility (GJH) is a risk factor for temporomandibular disorders (TMD). We examined 895 subjects (20-60 yr of age) in a population-based cross-sectional sample in Germany for GJH according to the Beighton classification and for TMD according to the Research Diagnostic Criteria for TMD(More)
