Evolutionary trends of the histological pattern in the teeth of Edentata (Xenarthra).
In a comparative study of the dental structure of Edentata, the central tissue was identified as a modified orthodentine, except in the Glyptodontidae where an osteodentine was found. Some evolutionary trends of the tissues in these teeth may have been related with the extinction of ground sloths. Comparative studies of the tissues in mammalian teeth seem to be good tests for systematics.
