Placing Arestin

I had a really great patient today that I had great learning experience with the patient being a couple quads of a class III and I was able to place an Arestin. I actually like these patients and experiences because they are not easy but meaningful. The next patient was a class V with many restorations. Sometimes these patients are the hardest for me because they could be totally clean but there are rough places where restorations are. These are not my favorite... but i'm sure are good experiances
