The goal of this study was to identify dental caries prevalence and severity among all 12 and 13-year-old schoolchildren enrolled in a public school in 2002 and to establish comparisons with the results of studies conducted previously in the same school in 1971 and 1997. A cross-sectional study involving 181 children was performed. Clinical data were collected by one examiner under World Health Organization (WHO) criteria. The examiner had been through calibration training. The project was approved by the Research Ethics Committee of the Federal University in Santa Catarina. The response rate was 93.8%. Intra-examiner agreement, on a tooth-by-tooth basis, was high (Kappa> or =0.73). The prevalence rates for dental caries were 98%, 93.7% or 80.0%, and 57.4% in 1971, 1997, and 2002, respectively. The mean DMF-T index was 9.2 in 1971, 6.2 or 3.0 in 1997, and 1.4 in 2002, taking both ages as a whole. The first value from 1997 was recorded under the Klein & Palmer diagnostic criterion and the second according to the WHO criterion. Between 1971 and 2002 there was a real reduction in caries prevalence and severity among the schoolchildren, even though different diagnostic criteria were used.
本研究的目的是确定2002年就读于一所公立学校的所有12岁和13岁学童的龋齿患病率和严重程度，并与1971年和1997年在同一所学校先前进行的研究结果进行比较。开展了一项涉及181名儿童的横断面研究。由一名检查者按照世界卫生组织（WHO）标准收集临床数据。该检查者已接受校准培训。该项目获得了圣卡塔琳娜联邦大学研究伦理委员会的批准。应答率为93.8%。检查者内部在逐个牙齿基础上的一致性较高（Kappa≥0.73）。1971年、1997年和2002年的龋齿患病率分别为98%、93.7%或80.0%以及57.4%。将两个年龄段作为一个整体，1971年的平均龋失补牙面数（DMF-T）指数为9.2，1997年为6.2或3.0，2002年为1.4。1997年的第一个值是根据克莱因&帕尔默诊断标准记录的，第二个值是根据WHO标准记录的。尽管使用了不同的诊断标准，但在1971年至2002年期间，学童的龋齿患病率和严重程度确实有所下降。
