TY - JOUR ID - TI - Does the size of the resorbed bone periapically predict the lesional type AU - Sabah M SAKA PY - 2001 VL - 1 IS - 3 SP - S267 EP - S270 JO - Al-Rafidain Dental Journal مجلة الرافدين لطب الأسنان SN - 18121217 19980345 AB - A retrospective study on (86)periapical lesions associated with non-vital anterior teeth was performed. The size of the resorbed bone caused by the lesion was measured to the nearest millimeters on the radiograph. Twenty two of the lesions were radicular cyst and the remaining (64) were granuloma or abscess.The size of the resorbed bone was related to the histological type of the lesion. It was possible to predict radicular cyst with (91.3%) accuracy before apical surgery is undertaken. In periapical granuloma or abscess, it Was possible to predict with (94%) accuracy. Therefore, selection of treatment modality whether conventional endodontic or apical surgery is possible
