本研究的目的是描述美洲印第安人 (AI) 人群在出生后 36 个月内的乳牙萌出情况，以比较 1) 男女儿童的乳牙萌出模式以及 2) 这些 AI 儿童与其他美国族裔群体之间的乳牙萌出情况。数据来源于来自北部平原部落的 239 名 AI 儿童的出生队列，这些儿童参与了一项早期儿童龋齿的纵向研究，检查数据的目标年龄为 8、12、16、22、28 和 36 个月（±1 个月）。对人工智能儿童的出现模式进行了表征，并使用区间审查生存方法完成了性别比较。通过 Kruskal-Wallis 测试，将每个年龄段的 AI 儿童萌出的牙齿数量与同龄儿童的牙齿数量进行比较，该测试来自亚利桑那州一项针对龋齿模式的横断面研究；这些比较基于 547 名非西班牙裔白人和 677 名西班牙裔儿童的牙科检查。实现各种里程碑的时间特征——包括前牙、第一磨牙和完整乳牙列的出现——没有提供人工智能儿童之间性别差异的证据。 AI 儿童在 8 个月时的牙齿数量（中位数为 3 颗）明显多于非西班牙裔白人（P < 0.0063）或西班牙裔（P < 0.0001）儿童（中位数为 2 颗）。 12 个月（P < 0.001；中位值分别为 8 与 6 和 7）和 16 个月（P < 0.001；中位值分别为 12 与 11）时也是如此。 22 个月时差异不太明显 (P < 0.0001)。非西班牙裔白人和西班牙裔白人儿童在任何时间都没有差异（P > 0.05）。这些结果提供了人工智能儿童比其他两个种族儿童更早出牙的证据。尽管人工智能儿童早期龋齿严重程度的潜在病因可能是多因素的，但较早的牙齿萌出可能是一个促成因素。知识转移声明：这项研究的结果对于为早出牙的族群提供儿童口腔保健的从业者具有实际意义。尽早向家长提供有关刷牙、看牙医和其他支持良好口腔健康的做法的信息可能很重要，以保护孩子的乳牙列。
The purposes of this study were to describe primary tooth emergence in an American Indian (AI) population during the first 36 mo of life to compare 1) patterns of emergence between male and female children and 2) tooth emergence between these AI children and other U.S. ethnic groups. Data were derived from a birth cohort of 239 AI children from a Northern Plains tribe participating in a longitudinal study of early childhood caries, with examination data at target ages of 8, 12, 16, 22, 28, and 36 mo of age (±1 mo). Patterns of emergence in AI children were characterized and sex comparisons accomplished with interval-censored survival methodology. Numbers of erupted teeth in AI children at each age were compared via Kruskal-Wallis tests against those in children of the same age, as drawn from a cross-sectional study of dental caries patterns in Arizona; these comparisons were based on the dental examinations of 547 White non-Hispanic and 677 Hispanic children. Characterization of time to achievement of various milestones-including emergence of the anterior teeth, the first molars, and the complete primary dentition-provided no evidence of sex differences among AI children. AI children had significantly more teeth present at 8 mo (median, 3) than either White non-Hispanic (P < 0.0063) or Hispanic (P < 0.0001) children (median, 2 each). This was also true at 12 mo (P < 0.001; medians, 8 vs. 6 and 7, respectively) and 16 mo (P < 0.001; medians, 12 vs. 11 each). Less pronounced differences were seen at 22 mo (P < 0.0001). White non-Hispanic and Hispanic children did not differ at any time considered (P > 0.05). These results provide evidence of earlier tooth emergence in AI children than in the other 2 ethnicities. Although the underlying etiology of the severity of early childhood caries in AI children is likely to be multifactorial, earlier tooth emergence may be a contributing factor. Knowledge Transfer Statement: The findings of this study have practical implications for practitioners providing childhood oral health care to ethnic groups with early tooth emergence. It may be important to provide parents with information on toothbrushing, dentist visits, and other practices supportive of good oral health as early as possible to protect their children's primary dentition.
