The palatally displaced canine (PDC) anomaly is a tooth malposition occurring in 1% to 3% of most populations. From the results of family studies, the PDC phenotype appears to be under strong genetic influence. In this study we report monozygotic (MZ) twin girls with bilateral PDC expression. The finding of PDC anomaly in MZ twins--to our knowledge, the first such published case--lends further support to evidence of genetic control of the PDC anomaly.
腭向错位尖牙（PDC）异常是一种牙齿错位畸形，在大多数人群中的发生率为1%至3%。根据家族研究结果，PDC表型似乎受到强大的遗传影响。在本研究中，我们报告了一对患有双侧PDC表现的同卵（MZ）双胞胎女孩。据我们所知，这是首次发表的同卵双胞胎中出现PDC异常的病例，这一发现进一步支持了PDC异常受遗传控制的证据。
