A longitudinal study on primary tooth eruption was performed in 114 Spanish children in two Primary Care Centers over 3 yr. Data from periodic observations and data collected by previously instructed parents was studied. Ages of tooth eruption were calculated for both sexes. Comparison between the two sides of the jaws showed a nonsignificant tendency towards earlier left side eruption. Comparison between maxillary and mandibular showed a significant earlier mandibular eruption for central incisors and second molars and a significant earlier maxillary eruption for lateral incisors. Comparison between sexes showed a tendency towards earlier eruption in boys for all teeth, significant only for mandibular central incisors, maxillary and mandibular lateral incisors and mandibular canines. Order of tooth eruption and its most frequent changes were also studied. When these findings were compared to studies performed in other populations it was concluded that ages and order of primary tooth eruption in Spanish children are similar to those found in other populations.
在3年时间里，对两个初级保健中心的114名西班牙儿童进行了一项关于乳牙萌出的纵向研究。研究了定期观察的数据以及由之前接受过指导的家长收集的数据。计算了男女的牙齿萌出年龄。颌骨两侧的比较显示左侧萌出略早，但差异无统计学意义。上颌和下颌的比较显示，中切牙和第二磨牙下颌萌出明显早于上颌，侧切牙上颌萌出明显早于下颌。男女比较显示，所有牙齿男孩萌出均略早，仅下颌中切牙、上颌和下颌侧切牙以及下颌尖牙差异有统计学意义。还研究了牙齿萌出顺序及其最常见的变化。将这些研究结果与其他人群的研究进行比较后得出结论，西班牙儿童乳牙萌出的年龄和顺序与其他人群相似。
