Biological clock linking tooth growth to other metabolic processes discovered

According to a press release that we received today, a New York University College of Dentistry professor has discovered a "biological clock" that he says links human tooth growth with other biological functions. The release says the next step, apparently, will be to see if this "clock" or growth rhythm affects human behavior. What do you think of trying to determine human behavior tendencies based on an individual's biological clock?
