Radiographically, a benign bone neoplasm is differentiated from a malignant one because in the benign lesion 1. the margins are irregular and fade into the surrounding bone. 2. the cortex remains intact. 3. there can be perforation of the periosteum. 4. the margins are defined and demarcated.

Which of the following statements is/are true?
1. Radiographs cannot differentiate between infected and non-infected periapical lesions.
2. A definitive diagnosis of an apical lesion cannot be made on radiography alone.
3. Periapical radiolucencies are not always indicative of loss of pulp vitality.
