Uh there were some seinal studies by Rooric and PESA in the '9s and 2000s that kind of delineated a lot of what Susan's talking about where they looked at uh CT scans of similar the same individual over time. I think some of those studies had a 15 to 20 year span and there was quantitative calculations of bone density and bone projection of the mandible, the maxilla, the frontal bone.
