Dr. Hall,
My employer assures me the radiolucent images of his Cerec crown margins are just radiographic burn-out and not poor margins. Can you support this?

Dear Hygienist,
It’s possible that a radiolucency at the margins of your CEREC crown are from radiographic burn-out. A better x-ray may help tell for sure.
If it is a gap at the margin, it should be clearly defined – you should be able to tell distinctly and precisely where the radiolucency begins and where it ends. If it is fuzzy – it just gradually fades into the tooth – then it’s probably radiographic burn-out. You may want to ask another dentist to look at it for you, if you have doubts.
