(1)背景顎のX線透過性病変は多数存在し、X線写真上類似していることが多いため、診断が困難な疾患である。また，類似した病変は学術文献によく記載されており，若手医師が鑑別診断を行う際に参考になることがある．この点に関する計量書誌学的分析の有用性は、まだ証明されていない。(2)方法本研究では，Web of Science Core Collection データベースに登録されている放射線透過性顎骨病変に関する学術文献を評価した．また、VOSviewerを用いて共起語分析を行った結果、放射線透過性顎顔面病変に関する記述は、文献の全記録から抽出された。(3)結果1897 本の論文をもとに、可視化マップを作成し、X 線透過性顎顔面病変の共起を評価した。アメロブラストーマは，歯原性角化嚢胞，歯原性嚢胞，放射状嚢胞との併存が多かった．骨異形成は，骨髄炎，骨化性線維腫，歯牙腫，線維性異形成，頂部歯周炎との併存が認められた．(4)結論放射線透過性顎骨病変の鑑別診断において，書誌学的解析の一種であるco-word解析は，関連性を示すことができる．

(1) Background: Many radiolucent jaw lesions exist, and they often show a radiographic resemblance, rendering diagnosis a challenging act. Closely related lesions should be frequently mentioned together in the academic literature, which might be helpful for junior practitioners in determining their differential diagnosis. The usefulness of bibliometric analysis in this respect has yet to be demonstrated. (2) Methods: This study evaluated academic publications on radiolucent jaw lesions, as indexed by the Web of Science Core Collection database. The mentions of radiolucent jaw lesions were extracted from the complete bibliographic records of the publications, and co-word analyses were conducted with the aid of VOSviewer. (3) Results: Based on 1897 papers, visualization maps were synthesized to evaluate co-occurrences of the radiolucent jaw lesions. Ameloblastoma was frequently mentioned together with odontogenic keratocyst, dentigerous cyst, and radicular cyst. Osseous dysplasia was co-mentioned with osteomyelitis, ossifying fibroma, odontoma, fibrous dysplasia, and apical periodontitis. (4) Conclusions: The co-word analysis, a form of bibliometric analysis, could demonstrate a relatedness of radiolucent jaw lesions that could be considered at differential diagnosis.
