日本东京近日公布的一项调查结果显示,6岁以下缺少关爱的儿童患龋齿的比例为一般儿童的两倍多,从而表明,儿童患龋齿与其缺少关爱有关。据报道,美国等国家的研究人员也正在进行有关忽视、怠慢或放弃对儿童的养育与儿童患龋齿因果关系的研究。 A survey released recently in Tokyo, Japan, shows that children under 6 years old who lack caring care have more than twice as many dental caries as their normal counterparts, demonstrating that caries are associated with lack of caring in children. It is reported that researchers in the United States and other countries are also conducting research on the causal relationship between neglect, neglect or abandonment of child-rearing and childhood tooth decay.
