Purpose: To evaluate treatment outcomes of a nonsurgical treatment approach after failed apicoectomy.
•N= 25 Teeth that had received primary root canal treatment and subsequent apicoectomy elsewhere before the patients presented with post-treatment disease. •Orthograde retreatment and obturation using an apical MTA plug was performed between 2004 and 2012.
•Pre-, intra-, and postoperative information and the potential effect on the retreatment outcome were evaluated
•In cases with in-conclusive information CBCT was used.
Most highlighted Results:
•Recall rate = 92% •follow-up periods ranged from 12 to 102 months
•(87%) were classified as ‘‘success,’’ and (17%) considered ‘failure.’’
•success rates were higher for single-rooted teeth. (Sig.)
– Orthograde retreatment combined with orthograde placement of an apical MTA plug is a promising long-term treatment option for teeth with postsurgical pathosis
