In a survey of 18,155 infants, 7,155 of whom were examined personally, the prevalence of natal teeth was one in 716 for the infants examined and one in 3,667 for those surveyed. Another group of 38 infants and children with 61 natal and neonatal teeth were examined prospectively. All were mandibular central incisors. Sixty-one percent of the subjects had a pair of natal or neonatal teeth (or both). Ninety-five percent of the natal and neonatal teeth were normal primary central incisors, and 5% were supernumerary primary central incisors. Initially, in 31% of the teeth, enamel dysplasia was seen, the occurrence of which correlated with the duration of the gingival covering. It is recommended that natal and neonatal teeth be left in place, if possible, and removed only if they are extremely mobile, such that reattachment is unlikely.
在一项对18155名婴儿的调查中，其中7155名婴儿接受了亲自检查，接受检查的婴儿中出生牙的患病率为716分之一，而在接受调查的婴儿中这一比例为3667分之一。另一组38名有61颗出生牙和新生牙的婴幼儿接受了前瞻性检查。所有牙齿均为下颌中切牙。61%的受试者有一对出生牙或新生牙（或两者皆有）。95%的出生牙和新生牙是正常的乳牙中切牙，5%是多生乳牙中切牙。最初，在31%的牙齿中可见釉质发育不全，其发生与牙龈覆盖的持续时间相关。建议尽可能保留出生牙和新生牙，只有在牙齿极其松动、不太可能重新附着时才予以拔除。
