Objective: Pulpal inflammation and necrosis can eventually cause periradicular diseases or apical pathologies, which are clinical and radiographically suggestive of an inflammatory sequel. Thus, the objective os this study is to compare the degree of agreement between the diagnosis of teeth with periapical lesions and histopathological analysis. Methodology: Fifty nine patients with surgical indication (teeth with lesions) were selected. In the radiographic analysis the appearance was observed, the size of the lesion was measured and a diagnosis hypothesis was suggested. Histological sections were examined under the microscope and the specimens classified as granuloma, cyst or chronic abscess. Results: The results showed 40.7% of concordance between the clinical-radiographic and histological diagnosis. According to histological analysis, 35.6% of the cases were granuloma, the cystic lesions corresponded to 59.03% and 5.09% were chronic abscesses. Conclusion: Thus, through only clinical and radiographic examination is not possible to confirm the diagnosis of lesions, because even images considered as cysts can be resulted from abscesses or granuloma, whereas the opposite may also occur.
