The use of dentures is becoming common even among Africans. So also is the problem of swallowed and impacted dentures. Their radiolucence makes radiological localization almost impossible, and because of their rigidity, large size, irregular and unyielding edges, impacted dentures are apt to produce lacerations during endoscopic removal from gullets rendered friable by impaction. Three patients with impacted radiolucent dentures are described in order to illustrate the problems of removal. It is suggested that the safest most effective method of removing impacted dentures in the esophagus is through an elective open esophagotomy.
假牙的使用在非洲人当中也日益普遍。吞下和嵌顿假牙的问题同样如此。它们的射线可透性使得通过放射学定位几乎不可能，而且由于假牙坚硬、尺寸大、边缘不规则且不易弯曲，在内镜下从因嵌顿而变得脆弱的食管中取出嵌顿假牙时，假牙容易造成撕裂伤。本文描述了3例嵌顿的射线可透性假牙患者，以说明取出假牙的问题。建议在食管中取出嵌顿假牙最安全有效的方法是通过选择性开放性食管切开术。
