Abstract
Design A 3-year pseudo-randomised controlled trial was conducted.
Intervention Subjects were randomly assigned by coin toss to either endodontic treatment and restoration with adhesive techniques and composite, or endodontic treatment and restoration with adhesive techniques and composite with final restoration with full-coverage metal-ceramic crown.
Outcome measure Restoration survival or failure was recorded. Causes of failure were categorised as root fracture, post fracture, post decementation, clinical and/or radiographic evidence of marginal gap between tooth and restoration, and clinical and/or radiographic evidence of secondary caries contiguous with restoration margins.
Results At 3 years there was no difference in the failure frequencies between the two groups.
Conclusions Clinical success rates of endodontically treated premolars restored with fibre posts and direct composite restorations after 3 years of service were equivalent to a similar treatment of full coverage with metal-ceramic crowns.
