Further caries decline in Swiss recruits from 1996 to 2006.

Previous investigations showed a steady decline of the caries experience. The purpose of this study was to determine the caries experience of Swiss recruits in 2006 and to compare it to that of 1985 and 1996. The results of a parallel investigation which dealt with the periodontal health of the same recruits have already been published (Röthlisberger et al. 2007). Investigations on recruits in 1970 (Curilovic et al. 1972) and 1974 (Curilovic et al. 1980) used another methodology. Therefore, they were not included here for comparison.
