The purpose of the present study was to determine the presence of radiopaque foreign bodies on oral and maxillofacial radiographs and classify them.
The Study Comment section of the Picture Archiving and Communication System of Chonnam National University Dental Hospital was searched using 30 key words to identify images with radiopaque foreign bodies recorded between November 2008 and March 2017. A total of 503 cases of radiopaque foreign bodies were selected from among the recovered images. The radiopaque foreign bodies were sorted into 19 types, which were subsequently divided into two categories according to whether the foreign bodies were inserted intentionally or unintentionally. The two categories were subdivided into five groups based on the cause of insertion: Treatment, Esthetics, Cultural, Iatrogenesis, and Accident.
In this study, the proportions of foreign bodies inserted intentionally (48%) and unintentionally (52%) were similar. When the foreign bodies were grouped based on the cause of insertion, the following frequencies were observed: Treatment, 41%; Esthetics, 7%; Cultural, <1%; Iatrogenesis, 51%; and Accident, 1%.
For adequate case management and to avoid unnecessary embarrassment and misinterpretation of unexpected radiopacities, clinicians should be familiar with the various types of foreign bodies and should ensure that detailed patient medical/dental history is obtained.
本研究的目的是确定口腔颌面X光片中不透射线异物的存在并对其进行分类。
使用30个关键词在全南国立大学牙科医院图片存档与通信系统的研究评论部分进行搜索，以识别2008年11月至2017年3月期间记录有不透射线异物的图像。从回收的图像中总共选择了503例不透射线异物病例。将不透射线异物分为19种类型，随后根据异物是有意还是无意插入分为两类。这两类根据插入原因细分为五组：治疗、美学、文化、医源性和意外。
在本研究中，有意插入（48%）和无意插入（52%）的异物比例相似。当根据插入原因对异物进行分组时，观察到以下频率：治疗，41%；美学，7%；文化，<1%；医源性，51%；意外，1%。
为了进行充分的病例管理并避免对意外的不透射线影像产生不必要的尴尬和误解，临床医生应熟悉各种类型的异物，并应确保获取详细的患者医疗/牙科病史。
