Teething is considered a significant event in the growth and development of the child by parents and especially by paediatric dentists and forensic scientists. They constantly need an “up-to-date mirror” of its variability for different geographic regions. The aims of the current study were to determine the timing and sequence of primary tooth emergence, and to establish a correlation between tooth eruption and general growth and external parameters in a sample of Romanian children. This study included 70 healthy children (53% girls and 47% boys), and the analysed data resulted from the questionnaires completed by parents during the whole process. General and specific data on primary teeth eruption were obtained. The differences between sexes were insignificant, except for the maxillary and mandibular canines (p = 0.047 and p = 0.018) and lower temporary second molars (p < 0.001), which were significantly increased in boys. The differences found between the two hemiarches were insignificant (p = 0.197). The mean age of eruption of the first tooth erupted was 7.07 ± 1.990 months. The unpaired t-test was used for comparison of the timings of eruption of the first primary teeth, according to the number of previous births and type of diet, and it was insignificant (p = 0.665 and p = 0.983 respectively).
出牙被父母，尤其是儿科牙医和法医科学家视为儿童生长发育中的一个重要事件。他们一直需要不同地理区域出牙情况变化的“最新反映”。本研究的目的是确定乳牙萌出的时间和顺序，并在罗马尼亚儿童样本中建立牙齿萌出与总体生长及外部参数之间的相关性。本研究纳入了70名健康儿童（53%为女孩，47%为男孩），分析的数据来自父母在整个过程中填写的问卷。获得了乳牙萌出的一般和具体数据。除上颌和下颌尖牙（p = 0.047和p = 0.018）以及下颌乳第二磨牙（p < 0.001）外，性别差异不显著，男孩的这些牙齿显著增多。两个牙弓之间的差异不显著（p = 0.197）。第一颗萌出牙的平均萌出年龄为7.07 ± 1.990个月。根据既往生育次数和饮食类型，采用非配对t检验比较第一颗乳牙的萌出时间，结果无显著差异（分别为p = 0.665和p = 0.983）。
