The prevalence of impaired oral health-related quality of life (OHRQoL) in Germany is unknown. The aim was to determine the OHRQoL distribution in the population and to derive population-based norms. OHRQoL was measured using the German version of the Oral Health Impact Profile (OHIP-G, 53 items) which was administered in a personal interview to 2050(More)
Case reports and cohort studies have linked bisphosphonate therapy and osteonecrosis of the jaws (ONJ), but neither causality nor specific risks for lesion development have been clearly established. We conducted a 1:3 case-control study with three dental Practice-based Research Networks, using dentist questionnaires and patient interviews for collection of(More)
OBJECTIVES We report the development and psychometric evaluation of short forms of the Oral Health Impact Profile German version (OHIP-G) - an instrument to assess oral health-related quality of life (OHRQoL). METHODS A five-item short form was developed using best subset regression in 2050 subjects from a national survey. Two 14-item versions were(More)
OBJECTIVES The purpose of this case-control study was to determine whether the radiographic appearance of the mandibular cortical bone in patients who were elderly and noninstitutionalized was related to a self-reported history of osteoporotic fractures.

Endpoints are conditions or events that are associated with individual study subjects and that are used to assess treatment efficacy. 2 types of endpoints can be distinguished: "true" endpoints (reflect unequivocal evidence of tangible benefit to the patient) and "surrogate" endpoints (usually a measure of disease process). The purpose of this study was to(More)
BACKGROUND AND OBJECTIVE The purpose of this study was to assess the oral health-related quality of life of patients presenting to a periodontal specialist by means of six questions, and to assess the perceived oral health by means of one question. Self-assessments of oral health were associated with clinical characteristics. MATERIAL AND METHODS Logistic(More)
Fifty-one patients were enrolled in this study to explore the treatment effects of material stiffness and frequency of appliance change when using clear, sequential, removable appliances (aligners). Patients were stratified based on pretreatment peer assessment rating (PAR) scores and need for extractions. They were randomized into 4 treatment protocols:(More)
Implant placement at the time of extraction has become an acceptable treatment option. The formation of a restorative treatment plan frequently requires the removal of questionable and hopeless teeth.
