To analyse differences in the eruption of primary teeth between both sexes.
A cross-sectional study was performed in a sample of 1250 children aged between 3 and 42 months. The clinical emergence of teeth was taken to estimate average ages for primary teeth eruption. The t-test was used to analyse gender and arch differences.
Eruption of primary teeth began at the same time in girls as in boys; although the eruptive process was longer in girls. It was observed that almost all deciduous teeth emerged earlier in boys, except for the first molar (upper and lower) and the maxillary central incisors. The differences were statistically significant for almost all the primary teeth except for the central incisors, both upper and lower.
By comparing the timing of the eruption of primary teeth in both sexes, it was found that eruption of almost all primary teeth took place earlier in boys than in girls and that the eruption process was shorter for boys than for girls. Most of the deciduous teeth erupted earlier in the right side in both sexes. No differences were found in the sequence of eruption of primary teeth between genders.
分析男女乳牙萌出的差异。
对1250名年龄在3至42个月的儿童样本进行横断面研究。通过临床牙齿萌出情况来估算乳牙萌出的平均年龄。采用t检验分析性别和牙弓差异。
女孩和男孩乳牙开始萌出的时间相同;尽管女孩的萌出过程更长。观察到几乎所有乳牙在男孩中萌出较早,但第一磨牙(上下颌)和上颌中切牙除外。除上下颌中切牙外,几乎所有乳牙的差异均具有统计学意义。
通过比较男女乳牙萌出的时间,发现几乎所有乳牙在男孩中比在女孩中萌出更早,且男孩的萌出过程比女孩短。男女两侧乳牙大多右侧萌出较早。男女乳牙萌出顺序无差异。
