I love the idea of partial coverage restorations: Being conservative and less invasive! But I hate seeing some of these restorations where there now is obvious decay in the interproximal area of the wall we did not reduce. Eventhough we made every effort to check for caries at the intial placement, there are times where they go undetected and surface years later. This is one of the few arguments against partial coverage. What adjuncts do you use to make sure the tooth structure you leave behind is not compromised?
