Two blog entries: /clinical/endodontics/how-far-down-the-root-canal-should-the-post-be-placed and /clinical/dental-trauma/in-vitro-evaluation-of-the-effect-of-post-system-and-length-on-the-fracture-resistance-of-endodontically-treated-human-anterior-teeth elicited significant activity…..thus I thought it pertinent to address the simplest way I know how to research the literature. As I get older, I’m less and less inclined to listen to eminence based advice or advocate information that comes with a paycheque. I want to know what the research says, granted even it is prejudiced by the sponsorship. We are capable of doing a basic yet substantial meta-analysis, pseudo-Cochrane Collaborative style review with elegance. The methodology – SCHOLAR.GOOGLE.COM – and the appropriate keywords….try it, you’ll never look back.
In this case it was “comparing cast post cores and glass fibre post cores” – this will scroll for some time because of the way Word Press sets up the fonts, but do try it.
