Periodontal attachment apparatus in the young Caiman sclerops

摘要: Abstract The tooth attachment apparatus of the crocodilian Caiman sclerops, was examined in animals 25–35 cm length (skull 4.0–5.5 approx). Sections were cut longitudinal and horizontal planes through jaws several animals. anterior teeth held a thecodont gomphosis but posterior ones lay bony channel. development interdental septa caudad direction initially related to orientation main supporting fibres found this gradual replacement double fibre system with single an associated septum is described. first formed consisted longitudinally arranged plates which subsequently remodelled form fibrous matrix running transversely across jaw. There also accompanying variations morphology cementum. Attention drawn primitive type cementum these creatures term “woven cementum” suggested. soft tissues, particularly oral epithelia, less well differentiated than those mammals.
