Bone dysplasias are radiographic findings showing radiopaque and radiolucent images, which are generally asymptomatic. It is essential to monitor these patients through periodic controls that include collection of radiographic exams, conventional x-ray and CBCT Scan, in addition to the face-to-face clinical examination. The dentist must be familiar with the diagnosis of these radiopaque and radiolucent lesions found on the radiographs that he performs daily, for a correct therapeutic approach. The objective of this work is to verify whether these images, seen in routine radiographs, evolve over time to a different type of image than the one initially found.
