The cementum layer was hypertrophic and consisted of two layers: the fibrous layer and the calcified layer. The two layers undergo developmental changes as a result of resorption and replacement. During the tooth replacement in the American alligator, trace elements decreased at the base of the dentine layer; the resorption of the alveolar bone occurred simultaneously at the tooth socket. We concluded that the resorption of the cementum in the alligator provided a useful indication of the mechanism of tooth replacement in crocodilian.<\/jats:p>","DOI":"10.1002\/jmor.1052110309","type":"journal-article","created":{"date-parts":[[2005,2,24]],"date-time":"2005-02-24T15:27:21Z","timestamp":1109258841000},"page":"319-329","source":"Crossref","is-referenced-by-count":10,"title":["Morphology of the tooth of the American alligator (<i>Alligator mississippiensis<\/i>): The fine structure and elemental analysis of the cementum"],"prefix":"10.1002","volume":"211","author":[{"given":"K.","family":"Shimada","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Sato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Moriyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,2,6]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7998.1979.tb03942.x"},{"key":"e_1_2_1_3_1","first-page":"733","article-title":"Observations on the teeth of reptiles","volume":"33","author":"Bradford E.
