引言：目前临床医生没有评估唇闭合强度（LCS）的诊断标准。本研究的目的是探讨模式的年龄相关的变化，在LCS和相关因素与LCS。方法：在总数为554名3-12岁的儿童参加了这项研究。他们没有严重的龋齿，也没有嘴唇或下颌功能障碍。我们用测力仪测量了孩子们的LCS，他们的父母完成了一份24项的问卷。统计分析采用非配对t检验和Pearson相关系数test.Findings：LCS显着增加，从3至6岁，但达到一个平台期，从7至12岁。在3-12岁之间，LCS迅速增加，直到婴儿期，其轨迹与Scammon生长曲线中观察到的一般类型相似。在3 ~ 6岁年龄组中，“年龄”与LCS的相关系数高于其他项目之间的相关系数，而在7 ~ 12岁年龄组中，“性别”和“进餐时饮用液体”与LCS的相关系数为中等。在白天养成闭上嘴唇的习惯对儿童来说非常重要。这些结果表明，儿童的LCS可能有两个不同的阶段，一个是发展期（3-6岁），另一个是稳定期（7-12岁）。(c)2017年日本儿童牙科学会。由爱思唯尔有限公司出版。保留所有权利。
Introduction: No diagnostic standard for assessing lip-closing strength (LCS) currently exists for clinicians. The aim of this study is to examine patterns in age-related changes in LCS and factors associated with LCS.Methods: In total, 554 children aged 3-12 years participated in this study. They had no serious dental caries and no lip or mandibular dysfunction. We measured the children's LCS with a force device, and their parents completed a 24-item questionnaire. Statistical analyses were performed using the unpaired t-test and Pearson's correlation coefficient test.Findings: LCS increased significantly from 3 to 6 years of age, but reached a plateau phase from 7 to 12 years of age. Between the ages of 3-12 years, LCS rapidly increased until infancy in a similar trajectory to the general type observed in Scammon's growth curve. In the 3 to 6-year-old age group, the correlation coefficient between "Age" and LCS was higher than between other items, and "Gender" and "Drinking liquid during meals" moderately correlated with LCS in the 7 to 12-year-old age group. The acquisition of the daily habit of closing the lips during the daytime is very important among children. These results indicated that LCS in children might have two different stages, one is a period of development (3-6 years old) and the other is a stable period (7-12 years old).
