A static, unilateral, and focal bone depression located lingually within the ascending ramus, identical to the Stafne's bone cavity of the angle of the mandible, is being reported. During development of the mandible, submandibular gland inclusion may lead to the formation of a lingual concavity, which could contain fatty tissue, blood vessels, or soft tissue. However, similar occurrences in the ascending ramus at the level of the parotid gland are extremely rare. Similar cases were previously reported in dry, excavated mandibles, and 3 cases were reported in living patients...

OBJECTIVE: The current staging system of medicine-related osteonecrosis of the jaws (MRONJ) assigns patients to different stages based on clinical manifestations. The extent of bone disease cannot be fully determined without radiologic evaluation. Missing radiologic information may lead to incorrect classification of MRONJ, resulting in poor outcomes of treatment. The objective of this study was to compare computed tomography (CT) and panoramic radiography (PR) features of MRONJ in different stages to achieve accurate staging on the basis of combined findings from clinical staging and imaging...
