A Study Of Cementifying Fibroma / 대한구강악안면방사선학회지

Cementifying fibroma is an odontogenic tumor of periodontal ligament origin, consistingof a proliferation of fibrous tissue that forms cementum. Cemento-ossifying fibroma, cemenrifying fibroma and ossifying firoma are difficult to distinguish on clinical and radiographic examination, and on histoapathology. However, when the calcified products is represented by ovoid or curvilinear deposites, the lesion is often referred to as cementifying fibroma. Cementifying fibroma of the jaws are well-circumscribed, generally slow-growing lesions. Although most lesions appear to be limited to the tooth-bearing areas, a few have extended into the angle-ramus area or encroached on the maxillary sinus. Radiographically, the cementifying fibroma could present as a radiolucent, radiopaque or mixed density lesion, depending on the degree of maturity. We have oberved two cases f cementifyingfibroma occurred in the left maxillary premolar-molar area of 38-year-old woman and 35-year old man. We obtained that two cases were shown the followed results ; 1. Clinically, main clinical sympton was facial swelling and pain at palpation. 2. Radiographically, well-circumscribed radiolucent lesion and radiolucent lesion with radiopaque foci were seen on the left maxillary premolar-molar areas. Loss of lamina dura and root resorption or divergency were also seen. 3. Histopathologically, many cementum-like calcifications were observed in the hypercellular connective tissue.

A study of the traumatic bone cyst / 대한구강악안면방사선학회지

Traumatic bone cyst is a pathologic cavity that is not lined with epithelium. It is, therefore, not a true cyst. It may be a normal variant rather than a disease process. The etiology of the condition is unknown. This condition is occured widely ranging ages(2 to 75years), however, most are found during the second decade of life. Radiographically, this condition is radiolucent lesion with well-defined outline, scalloping of superior margins. Cyst enucleation and curettage is the treatment of choice. The authors compared and analyzed the clinicoradiologic features of the five cases of traumatic bone cyst, diagnosed at the Dental college hospital in Chosun University, Kwangju, Korea. The five cases were shown the follwed results; 1. 3cases occured in second decade of life and no significant sex differences (M:F, 2:3) All cases occurred in mandible. 2. Two patients complained symptoms, but three cases had no symptom with encountering during routine examination. 3. In 3 of 5cases, teeth vitality existed except one tooth and no checking of teeth vitality in two cases. 4. All cases didn't have any accurate trauma history, but one case was in orthodontic treatment, another case was postextraction site area. 5. Radiologically, "scalloping appearance" were evident in all cases; in 3 cases, multilocular tendency and only one case seen intact mandibular canal image. 6. Histologically, alll section showed bone trabeculae with blastic activity, 2 cases showed no epithelial lining, and other 2 cases were seen innflammatory cell infiltration in edematous tissue. 7. Surgical intervention (curettage) was that treatment of choice.
