摘要: The fine structure and the concentration of trace elements in cementum layer functional teeth subadult alligators (ca. 120 cm to 160 total length) was studied by using scanning electron microscopy (SEM), microradiography, microprobe analysis (EMPA). hypertrophic consisted two layers: fibrous calcified layer. layers undergo developmental changes as a result resorption replacement. During tooth replacement American alligator, decreased at base dentine layer; alveolar bone occurred simultaneously socket. We concluded that alligator provided useful indication mechanism crocodilian.
