I conducted a retrospective study based on record reviews of 50,892 infants born at the Foothills Provincial Hospital, Calgary, Alberta, Canada, from 1967 to 1984 to determine the incidence and possible causes of natal teeth. Fifteen infants were affected, for an incidence rate of one in 3,392 births. The affected teeth were the lower central incisors. The condition was more common in female infants. Two of the affected patients were twins. One patient each had Ellis-van Creveld syndrome, Pierre Robin syndrome, adrenogenital syndrome, cleft palate, and rickets. One mother each had pernicious anemia, vaginal infection, and diabetes mellitus.
我基于对1967年至1984年在加拿大艾伯塔省卡尔加里山麓省立医院出生的50892名婴儿的病历回顾进行了一项回顾性研究，以确定诞生牙的发病率和可能病因。15名婴儿受影响，发病率为每3392例出生中有1例。受影响的牙齿为下颌中切牙。这种情况在女婴中更常见。两名受影响的患者是双胞胎。各有一名患者患有埃利斯-范克里维尔德综合征、皮埃尔·罗宾综合征、肾上腺生殖器综合征、腭裂和佝偻病。各有一名母亲患有恶性贫血、阴道感染和糖尿病。
