摘　　要：目的观察牙骨质—骨化纤维瘤的X线表现,并探讨其X线表现的病理学基础。方法牙骨质—骨化纤维瘤患者25例,男性7例,女性18例,初诊年龄12—65岁,平均38.5岁,上颌4例,下颌21例。观察牙骨质—骨化纤维瘤的X线表现,并从其病理表现分析其病理学基础。结果牙骨质—骨化纤维瘤的X线表现共分为三类:(1)密度减低影像。病理学上主要为富含成纤维细胞的纤维结缔组织构成。(2)密度减低—密度增高的混合影像。病理学上主要为含有牙骨质团块、编织骨及小梁状骨的纤维结缔组织构成。(3)密度增高影像。病理学上主要为牙骨质团块及小梁状骨构成,而纤维结缔组织成分较少。结论随着牙骨质-骨化纤维瘤病变内部硬组织含量和钙化程度的不同,从而有不同的X线表现,并且结合X线表现及其病理学基础,能够判断牙骨质-骨化纤维瘤的病变特性。Objective To observe the radiological manifestations of cemento-ossifying fibroma （COF） and investigate the pathological basis of its radiological pattern. Methods Twenty-five cases of COF were studied , including 7 male patients and 18 female patients , 4 maxillary lesions and 21 mandibular lesions , aged from 12 to 65 years old. The radiographic pattern of COF was observed and its pathological basis was analyzed. Results The radiological manifestations of the COF included three kinds. ① radiolucent appearance. It was pathologically consisted of fibrous connective tissue rich in fibroblasts. ②mixed radiolucent-radiopaque appearance. It was pathologically consisted of cemental mass, woven bone and trabecular bone mixied with fibrous connective tissue. ③ radiopaque appearance. It was pathologically composed of cemental mass and trabecular bone completely. Conclusion The radiological manifestations of the COF varied according to the content of hard tissue and its calcifying degree in the lesion. The process feature of COF was decided by its radiological manifestations and pathological basis.
