(1) Radiographs cannot differentiate between infected and non-infected periapical lesions. For example, acute apical periodontitis may have no radiographic change.
(2) A definitive diagnosis of an apical lesion cannot be made on radiography alone.
(3) Radiolucency image, such as mental foramen, periapical Cemento-osseous dysplasia are associated with vital teeth.
(4) One of the limitation of radiographic image is that the three dimensional object interpreted by two dimensional images. A periapical radiograph can not be used to locate the buccal bone level as the superimposition of buccal and lingual structures.
