A study of 528 Guatemalan children indicated that caries prevalence in the deciduous dentition was twice as great as but in the permanent dentition was similar to that for US white children. This is a repeated observation for children of some preindustrial societies. Caries experience was significantly greater in boys. Until 4 years of age, caries attack was greater in the anterior segment of the oral cavity; linear enamel hypoplasia was a predisposing factor.
一项针对528名危地马拉儿童的研究表明,乳牙列的龋齿患病率是美国白人儿童的两倍,但恒牙列的龋齿患病率与美国白人儿童相似。这是对一些前工业化社会儿童的反复观察结果。男孩的龋齿经历明显更严重。在4岁之前,口腔前部的龋齿发病率更高;线性釉质发育不全是一个诱发因素。
