摘要
本文报道了昆明市8148例儿童恒牙(第三磨牙除外)萌出时间的横断面调查,对恒牙萌出与年龄、身高、体重和月经初潮的关系进行了探讨。经相关分析,恒牙萌出数与年龄高度相关,与身高和体重低度相关,并建立了由年龄、身高或体重推算萌牙数的回归方程。还发现恒牙萌出与青少年性成熟也有一定的联系。提示恒牙萌出也能反映儿童的生长发育状况,故可作为衡量儿童生长发育的一项指标。
A cross-sectional investigation about erupting time of every permanent tooth except the third molars was performed among 8148 children and adolescents aged 3 to 18 in Kunming, Yunnan province. The relation of the number of erupted teeth (NET) to age, height, weight and menarche was studied.
Using analysis of correlation, NET correlates strongly with age (r = 0.9951 for boys and r = 0.9867 for girls, and p< 0.001 for both), but only weakly with both height (r = 0.2137-0.4070, p< 0.001 for all) and weight (r = 0.1965-0.3735, p< 0.001 for all) in children of same age. Twenty six regression formulae from age, height and weight were developed. In addition, a certain association between NET and sexual maturation was found. This indicates that eruption of the permanent teeth is able to reflect children's development too. Therefore, it may be regarded as an index of evaluation of growth and development in children.
