The custom of canine bud removal has detrimental consequences on children's general health and dental care. The objective of this study was to assess whether the prevalence of missing primary canines and dental defects in offspring of emigrants from Ethiopia is greater than in offspring of native Israeli parents of similar socioeconomic class.
477 children of Ethiopian descent and 317 offspring of native Israeli parents, from 21 nursery schools and kindergartens, underwent dental examinations aimed to determine the presence or absence of primary canines and of developmental enamel defects on adjacent teeth to the primary canines. For purposes of analysis, children were classified into two age groups: younger (ages 18-48 months) and older (ages 49-82 months).
Canines were present in more Israeli than Ethiopian younger children, 87.5% vs. 42.3%, p=0.0001; and in more Israeli than Ethiopian older children, 92.6% vs. 40.4%, p=0.0001. More dental defects were detected in Ethiopian than in Israeli younger children, 32% vs. 3.9%, p=0.0001; and in more Ethiopian than Israeli older children, 31.2% vs. 5.8%, p=0.0001.
The prevalence of missing primary canines and dental defects was greater among offspring of parents who had emigrated from Ethiopia 15-20 years earlier than among offspring of native Israeli parents living in the same low socioeconomic neighborhoods.
幼犬切除术的习俗对儿童的整体健康和牙齿护理有不利影响。本研究的目的是评估埃塞俄比亚移民子女缺失乳犬齿和牙齿缺陷的患病率是否高于具有相似社会经济阶层的以色列本土父母的子女。
477 名埃塞俄比亚裔儿童和 317 名以色列本土父母的子女，来自 21 所幼儿园和托儿所，接受了牙齿检查，以确定乳犬齿是否存在以及乳犬齿相邻牙齿是否存在发育性牙釉质缺陷。为了进行分析，将儿童分为两个年龄组：较小的（18-48 个月）和较大的（49-82 个月）。
以色列的较小儿童中，犬齿的存在率高于埃塞俄比亚儿童，分别为 87.5%和 42.3%，p=0.0001；以色列的较大儿童中，犬齿的存在率高于埃塞俄比亚儿童，分别为 92.6%和 40.4%，p=0.0001。埃塞俄比亚的较小儿童中，更多的牙齿缺陷被发现，为 32%，而以色列儿童为 3.9%，p=0.0001；埃塞俄比亚的较大儿童中，更多的牙齿缺陷被发现，为 31.2%，而以色列儿童为 5.8%，p=0.0001。
15-20 年前从埃塞俄比亚移民的父母的子女中，缺失乳犬齿和牙齿缺陷的患病率高于生活在同一低社会经济阶层社区的以色列本土父母的子女。
