Aim of this 2-year follow-up study was to assess the dental health status and the caries pattern of first permanent molars in German and immigrant children. 300 German and 69 immigrant children living in the Westphalian Ennepe-Ruhr district were involved in this study. The mean age of the population was 8.0 years at the baseline (1997) and 9.8 years at the second examination. The surface-related caries status according the WHO criteria (1997) was completed by recording non-cavitated lesions and the number of sealants in permanent molars. 13 % (1997) and 26 % (1999) of the 8-year old immigrant children had a caries-free mixed dentition; in Germans were recorded 40 % (1997) and 42 % (1999). The caries prevalence in immigrant children (1997: 0.9 DMFS/1999: 1.5 DMFS) was significantly higher compared to the German children (1997: 0.5 DMFS/1999: 0.8 DMFS). Moreover, a significantly lower utilisation of fissure sealants was registered in immigrant children (1997: 0.4/1999: 0.7) compared to their German classmates (1997: 0.5/1999: 1.4). Immigrant children have to be characterized as high caries-risk population. Risk-orientated public dental health programmes involving sealant application seems to be necessary for socio-economically underprivileged children.

If we wish to achieve a better understanding of the treatment needs in the delivery of primary dental services, we need to know why differences in dental caries recorded in the general practice and survey settings occur and the reasons for these differences. We also need to know how this factor influences the volume and type of treatment planned, both for the individual skilled benchmark epidemiologist and practitioner, and for mean world extremes on the other hand. This paper reviews estimates of dental caries treatment needs from the perspective of translation of dental caries status to estimates by need, estimation of need for dental care at the time of examination, differences in caries diagnosis between the epidemiologist and clinician and the consequences thereof, and changes in the presentation of dental caries that have occurred over the years. It is evident from this review of dental caries treatment needs that although the past record of dental epidemiology and clinical diagnosis can be defended, we cannot afford to do what has been done in the past, which was appropriate for lesions seen in the 1960s and 1970s, to the disease as it occurs in the 1990s.
