AIM/PURPOSE: To investigate the correlation between the histopathology of periapical lesion of endodontic origin and the radiographic findings of the maxillary sinus observed by cone-beam computed tomography (CBCT).
MATERIAL AND METHODS: Retrospective record review study, data collected of patients received surgical root canal treatment at Boston University school of dental medicine. Total of 39 periapical lesions all had CBCT scans and pathology reports. Each periapical lesion was biopsied and examined by oral & maxillofacial pathologist. CBCT scans for each lesion were examined by two examiners: endodontic resident and board-certified endodontic faculty.
RESULTS: 65% of the lesions associated with changes in the maxillary sinus and 35% had no changes as seen on the CBCT scans. 82% of the lesions were granulomas 15.5% were cysts and 2.5% OKC. Out of the 65% (26 lesions) maxillary sinus changes were 50% (13) were periapical mucositis (PAM) & 50% (13) were periapical osteoperiostitis (PAO).
CONCLUSION: Histopathology of the periapical lesion didn’t have an effect on the type of changes observed in the sinus. And the closer the lesion was to the sinus the more chances of developing changes in the sinus.
