Abstract

Objectives: This study aimed to analyze subchondral cyst on the mandibular condyle using fractal dimension (FD) measurement on a panoramic radiograph. Methods: This retrospective study examined 15 patients aged 24 to 75 years who had undergone panoramic radiography and cone-beam computed tomography on both sides of the mandibular condyles, between January 2013 and November 2017, in the Oral and Maxillofacial Radiology Clinic, Dental Hospital, Mahidol University. These 15 patients, all of whom had a subchondral cyst on one side of the mandibular condyle, constituted both the study and control groups: the 15 affected sides constituted the study group, and the 15 unaffected sides constituted the control group. The FD of both groups was calculated by two investigators using ImageJ version 2.0x. Results: The average age of the subjects was 47.47 ± 15.99 years. The mean FD value was 1.306 ± 0.133 in the study group and 1.409 ± 0.858 in the control group. The FD values were significantly different between these groups (p-value 0.016). Conclusion: The FD values of mandibular condyle were lower in patients with subchondral cysts than in healthy patients. The fractal analysis provided clinicians with extra information regarding the condition of the subchondral cyst as an early sign of osteoarthritis on panoramic radiographs.

Abstract

Objectives: This case report is aimed to show the radiographic features of fibrous dysplasia, a rare benign condition of abnormal bone growth that progresses slowly and is marked by uneven bone trabeculae interspersed with excessive proliferation of cellular fibrous connective tissue. Case Report: An 18-year-old female patient with a chief complaint of swelling on the right upper cheek was referred to the Oral and Maxillofacial Department of Universitas Indonesia Hospital. The patient is then referred to the Radiology Department to undergo a panoramic and CT scan examination. On panoramic and CT examination, signs typical of polyostotic fibrous dysplasia were found, namely “ground glass appearance” with ill-defined borders, which extended unilaterally and extended from the maxilla and mandible to the frontal bone. Conclusion: Polyostotic fibrous dysplasia can be identified on panoramic radiographs, a reliable and widely available diagnostic tool. Computed tomography (CT) is an advanced imaging modality for further evaluation of the lesion extension and tissue involvement. Management requires careful consideration of multiple clinical and radiographic factors.
