27 case reports and 1 case series were identified for this review of nerve damage due to over-extruded endodontic materials providing very low quality evidence for management of the problem.

This review only identified 5 small studies that provided insufficient evidence to compare outcomes using sodium hypochlorite and chlorhexidine for root canal disinfection. Additional high quality RCTs are required.

This RCT found no differences between single and multiple visit root canal treatment outcomes at 18 months Success rates for single visit treatments were 88.9% compared with 87.4% for multiple visits

This review of coronal pulpotomy in permanent teeth demonstrated good survival at 2 years 92% (95%CI; 84 -100). However as the majority of studies were observational they should be viewed cautiously until further high quality RCTs are available.

This Cochrane review was seeking to identify RCTs of interventions for the management of external root resorption in permanent teeth. No published trials were identified, so clinicians must decide on the most appropriate means of managing this condition according to their clinical experience with regard to patient-related factors.

Ten studies including both in vivo and ex-vivo designs were included in this review of electronic apex locators. The authors found that precision varied with the device and type of irrigation but was not influenced by the status of the pulp tissue. However, the quality of the included studies was not high with only two being considered to be at low risk of bias.

This technology review looked at the effectiveness of crowns on root treated teeth. 3 systematic reviews and 4 non-randomised studies were included. They found that the short term survival with crowns or direct fillings is comparable but long term root canal treated teeth may have better survival.

This new review of root canal retreatment indirectly compares the outcomes of two approaches, non-surgical retreatment and microsurgery. Only 4 of the studies were RCTs but these did not involve direct comparison of the two approaches. Pooled success rates suggest better outcomes for the microsurgical approach.

This systematic review was looking to compare endodontic microsurgery with single implant placement. No studies directly comparing the two treatments were available. 44 studies of single implants and 6 studies of endodontic microsurgery found 2 -4 years survival rates for endodontic microsurgery were 94% and single implants 96%. The quality of the available evidence was moderate.

This review looks at whether large apical master files lead to better root canal treatment outcomes. Only a limited number of low quality studies are available so at present we are uncertain.
