Dr. Shmuel Bentov from BGU's Avram and Stella Goldstein-Goren Department of Biotechnology Engineering discovered that this species of crayfish protect their teeth against wear in a very specific and surprising manner: they produce a highly mineralized protective coating based on calcium phosphate, which is strikingly similar to the enamel of vertebrates. The ?enamel? in the crayfish tooth serves as a protective layer for the softer under layer that is made, similar to the rest of the exoskeleton, from amorphous calcium carbonate.
?Enamel is the best solution for coating masticatory (chewing) organs,? Bentov explains. ?We assume that in the course of evolution, both vertebrates and this crayfish independently developed enamel-like tissues to address similar needs. Crustaceans discard their old teeth during the molting events several times throughout their life, and grow new exoskeletons and teeth regularly and rapidly.?

If so, send me any ?cool? and interesting dental-related Facebook posting links you find from the current week and if it?s deemed ?dental cool? your post will be the next blog. You can share or post the links to my Facebook page or just send them to me via Facebook message.
Only rules are to keep it ?dental cool,? meaning related to dental and, well, cool!
