To assess the oral health status and concordance between monozygotic and dizygotic twin pairs.
After obtaining prior consent, a cross-sectional descriptive study was conducted among 9 monozygotic and 21 dizygotic twin pairs who were reared together. Perception towards oral health practices was assessed using a pre-tested questionnaire. The WHO oral health assessment form (1997) was employed to assess the oral health status. Zygosity determination was determined using the medical records, dermatoglyphics and details about chorionicity and number of placental cords. Pearson's correlation was calculated to determine the correlation among the monozygotic and dizygotic twin pairs.
The monozygotic twin pairs showed a greater correlation compared to the dizygotic twin pairs in dental caries, periodontal disease and malocclusion.
In the present study, monozygotic twin pairs showed a higher correlation rate than the dizygotic twin pairs, suggesting considerable evidence that genes play a significant role in the aetiology of dental caries, periodontal disease and malocclusion.
评估单卵双胞胎和双卵双胞胎对的口腔健康状况及一致性。
在获得事先同意后，对9对单卵双胞胎和21对双卵双胞胎进行了一项横断面描述性研究，这些双胞胎是在一起抚养长大的。使用经过预测试的问卷评估对口腔健康行为的认知。采用世界卫生组织口腔健康评估表（1997年）评估口腔健康状况。通过病历、皮纹学以及关于绒毛膜性和胎盘索数量的详细信息来确定双胞胎的合子性。计算皮尔逊相关性以确定单卵双胞胎和双卵双胞胎对之间的相关性。
在龋齿、牙周疾病和错牙合方面，单卵双胞胎对比双卵双胞胎对显示出更高的相关性。
在本研究中，单卵双胞胎对比双卵双胞胎对显示出更高的相关率，这表明有相当多的证据表明基因在龋齿、牙周疾病和错牙合的病因学中起重要作用。
