No matter how conscious the dental community is about the importance of evidencebased dentistry (EBD), it is rarely applied, mostly because of time limitations.

The Crown-or-Fill (CoF) website was recently launched (http://crownorfill.com/ or http://ebhnow.com/ apps/0010/index.php) under the umbrella of EvidenceBased Healthcare (now EBHnow; http://ebhnow.com/). The website was created by a group of researchers, developers, and experts in evidence-based healthcare at McGill University, Concordia University, and the University of Bern for the purpose of providing instant access to evidence-based publications on the treatment outcomes of dental restorations. More specifically, the 5-year failure rate of the single-unit restorative alternatives is provided after 2 pre-existing conditions of the posterior teeth have been selected (Fig 1): whether (a) the tooth
