The first quad of a four!

Sometimes you begin to think there are just no such things as class 4s, but then the clouds part and lo and behold there it is sitting in your chair! I saw my first quad of a class four. It was great, he came in later to finish treatment and after placing arestin he had improved drastically! That is one of the neatest parts of hygiene for me. He was pretty happy and seemed like he wanted me to call him after I was graduated. That felt pretty good.
