Large idiopathic osteosclerosis in the mandibular after exclude other bone diseases: a case report

Idiopathic osteosclerosis is an asymptomatic, localized radiopaque bone lesion characterized by a dense, homogeneous appearance and occurs independently of infection or systemic conditions. The aim of this case report is to increase awareness about idiopathic osteosclerosis and its differential diagnosis in the maxillofacial region. A 26-year-old female patient was referred to the oral medicine clinic for evaluation of a bone lesion identified on a panoramic X-ray. Upon clinical examination, no carious teeth were noted. The panoramic X-ray revealed a radiopaque lesion on the lower right side of the mandible, extending from the distal aspect of the second molar to the mesial aspect of the third molar. Cold testing and percussion were performed, both yielding positive results. Based on these findings, a diagnosis of idiopathic osteosclerosis on the right side of the mandible was confirmed. The present case revealed an incidental finding of a radiopaque, elliptical lesion between the lower right molars, measuring approximately 20 mm in diameter, with no evidence of bone perforation or clinical relation to the surrounding teeth.
