This review investigating the incidence of and influential factors on pulp necrosis and periapical pathosis of vital teeth following indirect restorations included 37 studies. The findings suggest an overal incidence of pulpal necrosis of 5.02% (3.70 to 6.52%).

This review of the clinical performance and complications of single crowns retained by the locking taper system included 12 studies. The findings indicate that the locking taper system had similar performance to the conventional Morse taper system although none of teh studies included direct comparisons.

Thibault Colloc in his first blog for the Dental Elf looks at this review comparing gingival displacement with conventional cords and cordless techniques. The findings suggest that the sulcus width displacement is increased with cord technique compared to cordless technique but the available studies are all at high risk of bias.

This review comparing whether implant supported crowns on short or standard implants have similar clinical outcomes in the posterior alveolar bone included 5 RCTs. the findings suggested no differences at one year but that shorter implants performed less well at 5 years.

This review evaluating the presence or absence of a ferrule influences the failure rate in fibre-reinforced composite (FRC) post-and-core restorations included 4 studies. While the findings indicate no differences in failure rates between restoration with and with out a ferrule the quality of the evidence is low.

Only 9 small RCTs were included in this Cochrane review of metal-free materials for prosthodontic restorations providing insufficient evidence to support or refute the effectiveness of metal-free materials for fixed prosthodontic treatment over metal-ceramic or other type of standard restorations.

This review of post-retained crowns on endodontically treated teeth included 9 RCTs. Findings suggest that that the number of remaining coronal walls and the use of posts are key factors for the success/ survival of these restorations. However the quality of the available evidence is low.
