Summary

<p>Abstract</p> <p>Background</p> <p>During the past decades, the prevalence of caries disease in the population of Western industrialized countries has decreased markedly. In children also, a reduction of dental caries experience has been reported by many authors. The aim of this paper was to evaluate the trend of dental caries prevalence in 12-year-old children living in the city of Sassari, (Italy), by five cross-sectional studies conducted in 1989, 1992, 1995, 1998 and 2004.</p> <p>Methods</p> <p>In all cohorts, dental caries (DMFT and SiC Index according to WHO indications), was measured. For each variable measured (DMFT and sub-indices, SiC Index), differences in proportions among the five cohorts during the fifteen years were tested using χ²-square test.</p> <p>Results</p> <p>The mean DMFT index decreased from 4.3 ± 3.1 in 1989 to 0.8 ± 1.5 in 2004. The prevalence of untreated caries (DT) had a notable decrease between 1992 and 1995, increased slightly between 1995 and 1998 and had the greatest decrease in 2004. The number of filled teeth remains low. The percentage of caries-free children increased from 10% to 64%, whereas the percentage of untreated caries changed from 44% in 1989 to 62% in 2004. SiC Index decreased from 7.8 in 1989 to 3.9 in 2004.</p> <p>Conclusion</p> <p>On the basis of the results of DMFT and SiC Index, caries experience has been reduced. The vigilance and the promotion of a higher standard of personal oral hygiene and dental check-ups are necessary to obtain an improvement of oral status in the future adult population and to reach the new WHO global goals.</p>
