Menghini, Giorgio D; Steiner, Marcel; Marthaler, Thomas M; de Crousaz, Philippe; Helfenstein, Ulrich; Bandi, Adrian (1994). Kariesbefall bei 7- und 12jährigen Schülern in der Schweiz : Resultate einer landesweiten Erhebung 1987-89. Schweizer Monatsschrift für Zahnmedizin, 104(5):585-597.

Abstract

Between 1987 and 1989, a random sample of school children aged 7 and 12 years in Switzerland was drawn. In the first stage, districts were chosen. Within the districts, 12 children in the two specified age groups were selected. In addition, Switzerland was subdivided into two strata. The children of stratum 2 had consumed fluoridated salt since birth while those of stratum 1 had only done so during the preceding 4 to 5 years but had benefitted since the age of 5 to 7 from dental health education programs using fluorides at school. The oral examinations were carried out according to the methodology of the World Health Organization. Attendance was 94% (1115 children). 47% of the seven-year-old children were caries-free, and the average dmft was 2.20 (95% confidence limits at 1.87 and 2.52). The average dt was 1.06. These children had an average DMFT of 0.40, with 77% having DMFT = 0. At the age of 12, the average DMFT was 2.03, with confidence limits at 1.73 and 2.33. On average, they had 0.45 DT and 38% of them were caries-free (DMFT = 0). There were only minor differences between the 2 strata. These results agreed well with the data from 6 local surveys carried out during 1987 to 1989. When compared with the majority of European countries, caries experience of Swiss children was fairly low.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
