The evaluated factors were: clinical signs and symptoms, size of the periapical lesion, root canal obturation, tooth restoration, apical retrofilling, and the operating surgeon. A significantly higher success rate was found in roots obturated 2 mm or shorter of the apex, in roots without post restoration, and after retrofilling of roots with apparently well… CONTINUE READING
