Table 1

Criteria for clinical and radiographic interpretation of success and failure.

Outcome of treatment	Clinical and radiographical findings at recall
Success	(1) Radiographically, the contours and width of the PDL space were within normal limits or slightly widened around an accidental overfill and the patient was free of symptoms. Slight tenderness to percussion for a brief postoperative period was considered acceptable. (2) The size of a preoperative radiolucent area decreased by at least 50%, and the patient was free of symptoms, or the contours and width of the PDL space had returned to the normal. (3) Absence of preoperative periapical radiolucency which remained unchanged over time.
Failure	(1) Periapical radiolucency was observed in the preoperative radiograph and remained unchanged or increased in size over time. (2) A root in absence of preoperative periapical pathosis developed a radiolucency over time.
