Abstract

OBJECTIVE

To describe the changes in dental caries prevalence and severity, in a group of primary schoolchildren. Two dental caries surveys were carried out, one in 1984 and the other in 1992.

MATERIAL AND METHODS

The dental caries indices were registered using the World Health Organization's criteria. A group of 6-7 years old schoolchildren living in the East Region of Xochimilco were included in the study. A total of 279 children participated in this study; 153 in 1984 and 126 in 1992.

RESULTS

The mean value of the deft index was 5.65 (SD 3.35) in 1984, and the mean value of the deft index was 4.89 (SD 3.7) in 1992. For the permanent dentition the DMFT was 0.51 (SD 1.0) in 1984 and 0.48 (SD 0.82) in 1992. Differences in dental caries indices, between the first and second survey, were significant only for the primary dentition in the six years old group (95% CI 0.36, 2.15). An increase in the proportion of filled teeth was found. However, the treatment needs are still very high (69% for primary teeth and 86% for permanent teeth).

CONCLUSIONS

The findings from this study seem to indicate little change in the prevalence and severity of dental caries in the population in the period of study.

摘要

目的

描述一组小学生龋齿患病率和严重程度的变化。进行了两次龋齿调查，一次在1984年，另一次在1992年。

材料与方法

使用世界卫生组织的标准记录龋齿指数。研究纳入了一群居住在霍奇米尔科东部地区的6 - 7岁学童。共有279名儿童参与了本研究；1984年有153名，1992年有126名。

结果

1984年乳牙龋失补牙面（deft）指数的平均值为5.65（标准差3.35），1992年为4.89（标准差3.7）。恒牙的龋失补（DMFT）指数1984年为0.51（标准差1.0），1992年为0.48（标准差0.82）。两次调查之间，龋齿指数的差异仅在6岁组的乳牙列中具有统计学意义（95%可信区间0.36，2.15）。发现补牙比例有所增加。然而，治疗需求仍然非常高（乳牙为69%，恒牙为86%）。
