人的含牙囊肿比较常见,但对其发病机制了解甚少。Main(1970),Browne(1975)认为含牙囊肿是在牙冠形成完成后由于缩余釉上皮内或上皮和牙釉质表面之间有液体积聚而成。Gillette及Weinmann (1958)则认为起源于牙囊以外的囊肿被正在萌出的牙齿穿入而成。Bloch—Jorgensen(1928)则相信一些乳牙根尖囊肿为恒牙长入从而形成含牙囊肿。作者用出生后两天和五天的仑鼠上颌第二磨牙胚移植到5至7周同种鼠的左侧颊袋内。接受生后五日鼠单个牙胚种植的动物总
Human dental cysts are more common, but their pathogenesis is poorly understood. Main (1970), Browne (1975) considered that the catenary cyst is due to the accumulation of fluid within the cuff or between the epithelium and the enamel after the formation of the crown. Gillette and Weinmann (1958) believe that cysts originating outside the tooth capsule are penetrated by the adorable teeth. Bloch-Jorgensen (1928) believes that some primary apical cysts are permanent teeth that form a cyst containing the teeth. The authors were transplanted into the left cheek pocket of a 5- to 7-week-old rat using a second-mover germ embryo of two weeks and five days after birth. The total number of animals that had been implanted on a single tooth germ of five days after birth
