This case history describes the problems that may arise when foreign materials are injected subperiosteally during a dental procedure. The diagnosis might have been more difficult if the material had not been sufficiently radiopaque to be detected on a radiograph.
本病例记录描述了在牙科手术过程中骨膜下注射异物时可能出现的问题。如果该材料的射线不透性不足以在X光片上被检测到,诊断可能会更加困难。
