We have evaluated 2,416 children of both sexes from Bauru, with mixed dentition, at the age between 7 and 11 years, enrolled in 18 public and private schools. In this article we propose to find out the percentage of normal occlusion and the distribution of maloclusions, according to the anteroposterior relationship between the dental archs (following the ANGLE3 classification). The results show a low percentual of normal occlusion, in a total of 11.47% from the studied population. Class I malocclusion was the most prevalent (55%), followed by class II (42%) and, by class III (3%).
我们评估了来自包鲁市的2416名7至11岁处于混合牙列期的儿童，他们就读于18所公立和私立学校。在本文中，我们打算根据牙弓之间的前后关系（按照安氏Ⅲ类分类法），找出正常咬合的百分比以及错牙合畸形的分布情况。结果显示，正常咬合的比例较低，在所研究的人群中仅占11.47%。Ⅰ类错牙合畸形最为普遍（55%），其次是Ⅱ类（42%），Ⅲ类最少（3%）。
