PURPOSE
To estimate dental caries prevalence and severity among all 12- and 13-year-old schoolchildren enrolled in a public school in 2005 and to establish comparisons with the results of studies previously conducted in the same school in 1971, 1997 and 2002.
METHODS
A cross-sectional study involving 190 children was carried out. A single calibrated examiner collected the clinical data according to the World Health Organization (1997) criteria.
RESULTS
The response rate was 90.0%. Between 1971 and 2005, the observed reduction in caries prevalence was 58.2%, whereas the mean DMFT Index declined from 9.2 to 0.8, which corresponds to a reduction of 91.3%. The significant caries index (SiC) reduced from 3.4 (CI 95% 3.0-3.8) in 2002 to 2.2 (CI 95% 1.8-2.5) in 2005.
CONCLUSION
This study indicates an actual decline in dental caries prevalence and severity among the schoolchildren during the studied period, even though different diagnostic criteria were used.
目的
评估2005年就读于一所公立学校的所有12和13岁学童的龋齿患病率及严重程度，并与此前于1971年、1997年和2002年在同一所学校开展的研究结果进行比较。
方法
开展了一项涉及190名儿童的横断面研究。由一名经过校准的检查者根据世界卫生组织（1997年）标准收集临床数据。
结果
应答率为90.0%。在1971年至2005年期间，观察到的龋齿患病率下降了58.2%，而平均龋失补指数（DMFT指数）从9.2降至0.8，降幅达91.3%。显著龋指数（SiC）从2002年的3.4（95%置信区间3.0 - 3.8）降至2005年的2.2（95%置信区间1.8 - 2.5）。
结论
本研究表明，在研究期间，尽管使用了不同的诊断标准，但学童的龋齿患病率及严重程度实际有所下降。
