This review of endodontic treatments for immature teeth included 7 small RCTs at medium to high risk of bias. They suggest that mineral trioxide (MTA) may provide better clinical outcomes in relation to apical closure but the findings should be interpreted with caution.

This review of molar-incisor hypomineralisation management only included 14 limited quality and mainly observations studies.For molars composites, preformed metal crowns or indirect restorations seem suitable but more high quality studies are needed.

This review of failure rate of single-unit prostheses versus direct restorations in vital posterior teeth included 14 studies (5 RCTs) finding that composite had a significantly higher failure rate than amalgams, regardless of the remaining tooth structure. For teeth with fewer than 2 remaining walls, direct restorations presented significantly higher failure rates than crowns .
