Abstract：
Foreign bodies may be a cause of concern in dental implant failure.
The aim of the present study was to assess the occurrence and to evaluate the types of radiopacities in dental extraction sites using cone beam computed tomography (CBCT).
The incidence, location, and types of radiopacities were evaluated in 180 CBCT scans.
Different radiopaque structures could be noted in 84 scans. Foreign bodies and remaining roots were frequently seen. Most of the radiopacities were attributed to remaining endodontic filling in upper and lower jaws in 25 scans in different locations. Remaining roots could be detected in 20 scans. Focal and diffuse radiopaque bony lesions were observed in 16 scans. Tissue response in the form of radiolucency could be seen more with endodontic foreign bodies. Tissue reactions to radiopaque filling remnants were seen in 6.11% of cases.
Foreign body remnants, mostly of endodontic fillings, were frequently seen in CBCT in upper and lower jaws. Evidence of tissue reactions to extraction remnants could be found. Endodontic filling remnants could be seen more in the upper jaw. Thorough examination of implant site for the presence of endodontic foreign body remnants should be stressed. Debridement of the extraction socket should be done carefully in endodontically treated teeth.

摘要：
异物可能是牙科植入物失败的原因。
本研究的目的是使用锥形束计算机断层扫描（CBCT）评估拔牙部位的放射性不透明性的发生和类型。
发病率,location,在180次CBCT扫描中评估了放射性不透明度的类型。
在84次扫描中可以注意到不同的不透射线结构。经常看到异物和剩余的根。在不同位置的25次扫描中，大多数放射性不透明度归因于上颌和下颌中残留的牙髓填充。可以在20次扫描中检测到剩余的根。在16次扫描中观察到局灶性和弥漫性不透射线的骨病变。在牙髓异物中可以看到更多的放射透过性形式的组织反应。在6.11％的病例中观察到对不透射线的填充残留物的组织反应。
异物残留,主要是牙髓填充物，常见于CBCT的上颌和下颌。可以找到组织对提取残余物反应的证据。在上颚可以看到更多的牙髓填充残留物。应强调彻底检查植入部位是否存在牙髓异物残留物。在经牙髓治疗的牙齿中，应仔细清创术。
