Abstract

OBJECTIVE

The aims of this study were to investigate and compare the prevalence of dental caries and the frequency of oral habits, molar relationships and occlusal traits between children of multiple births, and singletons, and to determine the relative contributions of genetics and environmental factors to these parameters by using twin study design.

METHODS

The study group consisted of 345 multiple births (34 monozygotic and 122 dizygotic twin pairs, 11 sets of triplets) and 345 singletons between the ages of 2 and 17. The prevalence of dental caries, and the frequency of tooth brushing, the children's oral habits, molar relationships, and occlusal traits were recorded.

RESULTS

The percentage of children who brushed their teeth more than twice daily was statistically significantly higher in multiple births than in singletons. Higher correlation coefficients were found in dental caries index, except for decayed, filled (df) (2-5 age group) and filled (f) (6-11 age group), in the monozygotic twin pairs compared to those in the dizygotic twin pairs. In children between the ages of 6 and 11 years, mouth breathing, bruxism, lip biting, and pencil biting were higher in singletons than in children of multiple births. There were statistically significant differences between children of multiple births and singletons, with increased overjet in the 2-5 year age group being observed.

CONCLUSION

When analyzing these parameters, environmental factors must also be investigated. Due to the low incidence of twin births, longitudinal follow-up studies with more twin pairs are necessary to determine whether these results are generalizable.

摘要

目的

本研究旨在调查和比较多胎儿童与单胎儿童的龋齿患病率、口腔习惯频率、磨牙关系和咬合特征，并通过双胞胎研究设计确定遗传和环境因素对这些参数的相对贡献。

方法

研究组包括 345 名多胎儿童（34 对同卵双胞胎和 122 对异卵双胞胎，11 组三胞胎）和 345 名单胎儿童，年龄在 2 至 17 岁之间。记录龋齿患病率、刷牙频率、儿童口腔习惯、磨牙关系和咬合特征。

结果

多胎儿童每天刷牙两次以上的比例明显高于单胎儿童。同卵双胞胎的龋齿指数（除 2-5 岁年龄组的龋齿、补牙（df）和 6-11 岁年龄组的补牙（f）外）的相关系数明显高于异卵双胞胎。6-11 岁的儿童中，口呼吸、磨牙症、咬唇和咬铅笔在单胎儿童中比多胎儿童更为常见。6-11 岁的儿童中，多胎儿童和单胎儿童之间存在统计学显著差异，2-5 岁年龄组的覆颌增加。
