 Hi, Dr. Jared here with today's Friday Flop and today's is on tooth number I. It is on a class 2 preparation and these are probably one of the most difficult with things we do in pediatric dentistry because we don't have a lot of room for our material and we need room for strength. So in this case, likely had inadequate reduction at the isthmith. We need to have that be about 1.5 millimeters in depth for us to have strength for alloy or RMGI to not fracture. So tip here would be to make sure that we have adequate thickness for the material that we are going to restore with. Have a great weekend.
