I have heard that kissing lesions can be a blessing or a curse on the WREB. I have a patient with two great lesions (one on the mesial of #4 and one on the distal of #5). I thought that the one on #4 was a little deeper and was going to restore it this week and just use the #5 lesion. One of our instructors saw both lesions and thought they would be great for the WREB. I know that in this situation you must restore one completely before submitting the other lesion to qualify. But his contact between the two teeth is light when using floss. According to the WREB "there must be no break in the proximal tooth structure of the adjacent tooth either before or during treatment." So I am left with two options; fill one and do only one or submit both and hope both qualify with the WREB examiners, while only having to use one patient. If anyone has had experience with this, please let me know.
