Many dental plates are made of materials that are radiolucent. If inhaled or swallowed they may be difficult to detect and where there is strong suspicion of inhalation, early bronchoscopy should be carried out even if plain X-rays show no abnormality. The details of three patients are reported.
许多牙托是由射线可透过的材料制成的。如果被吸入或吞咽，它们可能难以被检测到，并且在高度怀疑有吸入情况时，即使普通X光片显示无异常，也应尽早进行支气管镜检查。本文报告了三名患者的详细情况。
