- Investigate the effectiveness and frequency of short-term and long-term complications when endodontic treatment is completed in one or multiple visits.
- N= 12 articles met inclusion criteria
- Randomized and quasi-randomized controlled trials were identified by searching biomedical databases and handsearching relevant journals. Outcomes considered were: tooth extraction as a result of endodontic problems and radiologic failure after 1 year, postoperative discomfort, swelling, analgesic use, or sinus track.
- No detectable difference was found in the effectiveness between single and multiple visits.
- Patients undergoing a single visit might experience a slightly higher frequency of swelling and require more analgesic use.
No difference between 1 or 2-visit RCT in effectiveness of healing. Single visit may result in slightly more post-op symptoms.
