This case report describes the presence of a radiopaque artifact appearing in multiple intraoral periapical and bitewing radiographs during routine periodontal maintenance, in an edentulous area with a history of a ridge preservation procedure. Clinical examination of the area showed a normal soft tissue appearance. Upon further investigation of the patient's recent past medical history, it was found that the artifact was due to the presence of a dermal filler (Radiesse--Merz Aesthetics, San Mateo, CA), which remained after a facial cosmetic procedure. This unusual finding is an indication that clinicians should consider facial cosmetic dermal fillers as part of the differential diagnosis when unusual radiopaque objects are found during routine dental radiographs.
本病例报告描述了在一名有牙槽嵴保存手术史的无牙区进行常规牙周维护期间，多张口内根尖片和咬合翼片上出现不透射线伪影的情况。该区域的临床检查显示软组织外观正常。进一步调查患者近期病史发现，该伪影是由于面部美容手术后残留的一种真皮填充剂（瑞蓝——默克美学公司，加利福尼亚州圣马特奥）所致。这一不寻常的发现表明，临床医生在常规牙科X线检查中发现异常不透射线物体时，应将面部美容真皮填充剂作为鉴别诊断的一部分予以考虑。
