Accidental swallowing of a gold cast crown that became loose after separation with brass wire for orthodontic band placement, is reported. The intervention to remove the ingested crown subsequent to its location in the GI tract on immediate radiographic examination of chest and abdomen included endoscopic examination. Since the crown had past distal to the duodenum it was decided to keep a watch on its movement by daily radiographic examination. The crown passed with excreta on the 5th day uneventfully. Literature on ingestion of foreign bodies of dental origin is reviewed. Possible emergencies and their management is discussed.
据报道，有患者意外吞入了一颗正畸带环放置时用铜丝分离后松动的铸造金冠。在胸部和腹部进行立即X线检查发现金冠位于胃肠道后，采取的取出该摄入物的干预措施包括内镜检查。由于金冠已通过十二指肠远端，因此决定通过每日X线检查密切观察其移动情况。金冠在第5天随粪便顺利排出。本文回顾了有关牙科源性异物摄入的文献，并讨论了可能出现的紧急情况及其处理方法。
