OBJECTIVE
To investigate risk factors specific to posterior crossbite and anterior open bite at the age of 3 years.
MATERIALS AND METHODS
The study included 422 children of the French EDEN mother-child cohort. The main outcomes were the presence of posterior crossbite and anterior open bite assessed by dentists at 3 years. Social characteristics (collected during pregnancy), neonatal characteristics (collected at birth), duration of breast-feeding (collected prospectively), sucking habits at 3 years, and open lips (as a proxy for mouth breathing) were studied and two logistic regressions conducted.
RESULTS
Preterm birth appears to be a risk factor specific for posterior crossbite (OR: 3.13; 95% CI: 1.13-8.68), whereas small for gestational age seems to be associated with a lower risk of posterior crossbite (OR: 0.32; 95% CI: 0.12-0.87). Ongoing pacifier or thumb sucking at 3 years is a risk factor for both posterior crossbite and anterior open bite.
CONCLUSIONS
Children born preterm seem to be more at risk for posterior crossbite than those born at term. Different mechanisms may be involved in posterior crossbite and anterior open bite.
目的
研究3岁儿童后牙反合和前牙开合的特定危险因素。
材料与方法
该研究纳入了法国EDEN母婴队列中的422名儿童。主要结局是由牙医在3岁时评估的后牙反合和前牙开合情况。研究了社会特征（孕期收集）、新生儿特征（出生时收集）、母乳喂养持续时间（前瞻性收集）、3岁时的吮吸习惯以及张嘴（作为口呼吸的替代指标），并进行了两项逻辑回归分析。
结果
早产似乎是后牙反合的特定危险因素（比值比：3.13；95%置信区间：1.13 - 8.68），而小于胎龄儿似乎与后牙反合风险较低相关（比值比：0.32；95%置信区间：0.12 - 0.87）。3岁时持续使用安抚奶嘴或吮拇指是后牙反合和前牙开合的危险因素。
结论
早产儿童似乎比足月儿患后牙反合的风险更高。后牙反合和前牙开合可能涉及不同机制。
