| The cells that form new ivory lie at the base of the tusk where dentin meets the hard outer layer of the tooth, called cementum. A microscopic look at a cross section of one tusk revealed that the zones of dentin underlying the external pits were also damaged, Fisher reported in Ottawa last week at the annual meeting of the Society of Vertebrate Paleontology. The undesirable bacteria convert sugars into lactic acid making the acidic plaque powerful enough to de-mineralize the tooth enamel and the underlying dentin. |
