In 1995 a dental survey among adults aged 25-54 years was performed in 's-Hertogenbosch (The Netherlands). Aim was to study trends in oral health after 1983, a year in which a similar study was performed in the same city. Caries data were obtained by clinical examination only. The percentage of edentulous persons in the sample decreased with about 50% between 1983 and 1995. In 1995 in all age categories of dentate persons, the mean number of FT was higher, and the mean numbers of DT and MT were lower than in 1983. In persons with a natural dentition under the age of 35 the mean number of DMFT decreased significantly. It was concluded that oral health in adults living in 's-Hertogenbosch, as measured by caries prevalence, treatment level of caries and percentage of edentulous persons, improved significantly between 1983 and 1995. It is supposed that the trends found in 's-Hertogenbosch are indicative of changes in oral health in The Netherlands.
