Researchers have described a new, recessively inherited human syndrome featuring craniosynostosis, maxillary hyperplasia, delayed tooth eruption and extra teeth. They also identified causative mutations in a gene IL11RA. In craniosynostosis, the sutures between skull bones become ossified prematurely, affecting skull shape and limiting space for the growth of the brain. It is observed in 1:2500 and often requires operative surgery. Supernumerary teeth are more common, and in most cases they...

Same Study Uncovers How Each Tooth Signals the Next to Start Growing ROCHESTER, N.Y., Feb. 26 /PRNewswire-USNewswire/ -- A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published today in the journal Science. When completely understood, the genetic program described in the study may help guide efforts to re-grow missing teeth and prevent cleft palate, one of the most common birth defects. Gene...

Scientists have reported new insights gathered from a single gene that could one day be used to help adults grow a new set of teeth. Scientists from the University of Rochester bred mice that lacked the oddskipped related-2 (Osr2) gene. They noted that mice that lacked the gene grew an extra set of teeth next to their molars in similar fashion to sharks and other non-mammals. "It's exciting. We've got a clue what to do," Dr. Songtao Shi of the University of Southern California School of...
