The sinus is reduced to a small cavity with no sinus reaction.
Radicular cyst on 12 and 11, endodontic treatment is needed for both teeth followed by enucleation and biopsy.
Large fibrous dysplasia occupying the whole volume of the left maxilla, a larger volume is needed to assess the whole outline of the lesion, referring the patient for surgical evaluation and biopsy is needed. The lower density areas within the lesion are indicative of active phase of growth.
