Abstract
Data sources Medline, EMbase, Science Citation Index, US National Library of Medicine, along with searches made on the Internet.
Study selection Studies were included if they: had a random research design; were peer-reviewed; follow-up was at least 1 year; and if retrofilling material, the healing group, age, sex and teeth/roots, the number of surgeons, and the age and sex of patients were identified.
Data extraction and synthesis The outcome in each of the included studies was standardised to success, or to uncertain or unsuccessful outcome, and the weighted average was calculated.
Results Eight eligible studies were identified, involving 2375 patients and 2788 teeth. The weighted average for success with initial surgery was 64.2% with 25.7% uncertain and 15.75% unsuccessful. For patients undergoing a second surgery the weighted average success rate was 35.7% with 26.3% uncertain and 38% unsuccessful.
Conclusions In patients who underwent second surgery for radiographically-determined endodontic failure, 35.7% healed successfully.
