BACKGROUND Interpretation of scores from oral health-related quality of life (OHRQoL) instruments, such as the Oral Health Impact Profile (OHIP) is challenging. It was the aim of this study to determine how many oral impacts correspond to one point of the 49-item OHIP using a new approach which translates numeric problem counts into the traditionally used(More)
The study investigated the validity of the response format of the Oral Health Impact Profile 49 (OHIP-49). The OHIP-49 was completed by 145 consecutive prosthodontic patients. For each OHIP item, subjects completed the standard ordinal response format (with responses given as never, hardly ever, occasionally, often, or very often, and scored from 0 to 4,(More)
OBJECTIVES This study aimed to develop the German version of the Orofacial Esthetic Scale (OES-G) and to assess its psychometric properties. METHODS The OES is an eight-item instrument with seven items directly addressing esthetic impacts of the orofacial region and an eighth item for a global assessment. It applies an 11-point ordinal rating scale, with(More)
BACKGROUND Prospective assessments of oral health-related quality of life (OHRQoL) changes are prone to response shift effects when patients reconceptualize, reprioritize, or recalibrate the perceived meanings of OHRQoL test items. If this occurs, OHRQoL measurements are not "invariant" and may reflect changes in problem profiles or perceptions of OHRQoL(More)
Recording the track of the mandibular hinge axis and consequently ascertaining the posterior determinants is one of the key requirements for accurately simulating individual oral conditions in the (virtual) articulator. The aim of this study was to determine the reliability of computerized condylar path inclination angle (CPIA) measures and to assess(More)
