Abstract

Antrolith occurs within the maxillary sinuses and is circumscribed pathologic calcifications formed as a result of mineral salt deposition around an organic nucleus in the maxillary sinus. Radiographically, this lesion is a radiopaque mass showing variable sizes and shapes. Treatment by surgical removal is indicated only for large antrolith associated to clinical symptoms. CBCT should be required for treatment planning for implant-supported restorations in the maxilla because of the higher prevalence of anatomical variations and sinus disease. We report a 3 cases of antrolith which was found incidentally on panoramic images and CBCT, although there were no clinical symptoms.
