OBJECTIVES: To assess changes in the number of functioning teeth (filled and sound teeth, FS-T index) from 1989/1992 to 2005 in West and East Germany and to evaluate survey- and region-specific associations between sociodemographic and behavioral risk factors and the FS-T index. METHODS: Within the German Oral Health Studies, random samples from 35-44-year-olds were drawn in 1989, 1992, 1997 and 2005. The FS-T index and a questionnaire with socioeconomic and behavioral items were assessed. Negative binomial regression models were evaluated, including all sociodemographic and behavioral factors simultaneously as independent variables. RESULTS: For West Germany, median FS-T index increased by 3 teeth between 1989 and 2005 (Ptrend < 0.001). In East Germans, FS-T index was similar in 1992 and 1997 (median, 24), but increased by one tooth until 2005 (Ptrend < 0.001). For West and East Germany, middle and high school education were significantly associated with higher FS-T indices in all surveys, although effects were most pronounced in 2005. Being married, reporting regular dental visits and good oral hygiene were significantly related to a higher number of functioning teeth in at least one survey year. CONCLUSIONS: Dental health assessed as the number of functioning teeth improved between 1989/92 and 2005 in both German parts and across all educational levels. However, considering the educational level, dental health was less equally distributed in 2005 compared with previous surveys.
