A microanatomical and histological study of the postcranial dermal skeleton of the Devonian actinopterygian Cheirolepis canadensis [PDF]

open access: yesActa Palaeontologica Polonica, 2016
The Devonian stem-actinoterygian Cheirolepis canadensis is potentially important to understand the evolution of the dermal skeleton of osteichthyans, but the last detailed histological study on this taxon was published more than forty years ago.

Dentin Sialophosphoprotein (DSPP) and Dentin [PDF]

open access: yesJournal of Oral Biosciences, 2008
The revolution in genetics disclosed the types of malformations that occur when expression of a particular gene is lost. In the case of tooth dentin, mutations in the two genes encoding type I collagen cause osteogenesis imperfecta, a bone condition that often includes dentin malformations.

Tertiary Dentine Frequencies in Extant Great Apes and Fossil Hominins

open access: yesOpen Quaternary, 2019
Tertiary dentine forms when an odontoblast is directly affected by stimuli, commonly through occlusal wear and caries. In this study the presence of tertiary dentine was recorded in three South African fossil hominin species ('Australopithecus africanus,
