一般认为牙源性囊肿与肿瘤来源于牙板剩余。作者通过对恒磨牙牙板发育过程的研究得出结论,认为牙板剩余不一定是角化囊肿与造釉细胞瘤的主要起源。作者对10只恒河猴胚和8只小猴(年龄自妊娠后60天至出生后24个月)的颌骨进行了组织学观察。最初,胚胎第67天,见到第一恒磨牙牙板自第二乳磨牙远中向后增生。胚胎第81天,第一恒磨牙帽状期开始, Generally believed that odontogenic cyst and tumor derived from the remaining dental board. Through the study on the development of permanent molars, it is concluded that the residual of dental veneers is not necessarily the main origin of keratocysts and ameloblastomas. The authors performed a histological observation of the jaws of 10 rhesus macaques and 8 monkeys (age 60 days after gestation to 24 months after birth). Initially, on day 67 of the embryo, the first permanent molars plaque was seen to proliferate far from the second molars. On the 81st day of embryo, the first permanent molars hat began,
