This review of regenerative endodontic treatment (RET) or mineral trioxide aggregate (MTA) apical plug (MAP)in the treatment of teeth with pulp necrosis and open apices used broad inclusion criteria. 144 studies were identified suggesting promising outcomes. However the quality of the available evidence is very low and more high quality research is needed.

Inlay-retained fixed dental prosthesis have acceptable 3-yr survival rate suggests review

Missing premolar

This review of inlay-retained fixed dental prosthesis included 11 small mainly observational studies. The studies suggest a 3-yr survival rate of 92.6% (95% CI: 85.8-97.6%) and 5-yr survival rate of 87.9% (95% CI: 77.4-96.1%). However because of the low quality of the available studies and the wide range of inlay designs, framework materials, surface treatments and cement systems used means that the results should be interpreted cautiously.

45 studies are included in this review of endodontic treatment or implants for the pulpally involved tooth. The studies are are observational with few comparative studies and while they summarise success rates for various treatments they should be interpreted cautiously. High quality comparative studies are needed as well as agreement on common reporting outcomes.
