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.

This review of root perforation repair included 17 studies that were mainly retrospective and small. The overall success rates for all materials was = 72.5% (CI; 61.9%–81.0%) with a suggestion of better rates for MTA. However, the quality of the evidence was low.

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.
