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 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)
OBJECTIVES This study investigated the association between denture status, demographic factors, and oral health-related quality of life (OHRQoL). METHODS 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 subjects (60% of eligible subjects responded)(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)
AIM We assessed the prevalence and extent of periodontitis in Germany. Furthermore, region- and gender-specific differences in periodontal disease prevalence were evaluated. MATERIAL AND METHODS The fourth German Dental Health Survey is a national cross-sectional survey conducted in 2005. Nine hundred and twenty-five adults (35-44 years) and 1040 seniors(More)
OBJECTIVE The aim of this field study (the "Fourth German Oral Health Study") was to obtain representative data on caries (DMFT index), periodontitis (CPI) and prosthetic status in the German population and to evaluate changes in the oral health of the German people as compared with the findings of the Third German Oral Health Study conducted eight years(More)
This paper presents selected results of two recent representative cross sectional studies of oral health in the German population, conducted by the IDZ (Institute of German Dentists) for the old Federal States (the former Federal Republic of Germany) in 1989 (n= 1741) and the new Federal States (the former German Democratic Republic) in 1992 (n=1519).

OBJECTIVE To consider differential effects of income and education on oral health for each indicator separately and in combination. Finally the combined effects of the lowest income level and the lowest level of education were examined. METHODS Data were drawn from the Fourth German Oral Health Study. They were collected using proportional random sampling(More)
OBJECTIVES To investigate the frequency of impaired oral health-related quality of life (OHRQoL) in patients with dental anxiety. METHODS OHRQoL was measured with the German version of the 14-item Oral Health Impact Profile (OHIP) developed by Slade and Spencer (1994) in 173 adult patients with dental anxiety [Dental Anxiety Scale (DAS) score 15 or above(More)
AIM To assess periodontitis-related knowledge and its relation to oral health behaviour on a community level and to identify target groups and major topics for health education interventions. MATERIAL AND METHODS By means of a multistratified, stochastic telephone survey, 1001 interviews with Germans older than 14 years were carried out. Participants(More)
