A new rhynchocephalian from the late jurassic of Germany with a dentition that is unique amongst tetrapods. [PDF]
, 2012 Rhynchocephalians, the sister group of squamates (lizards and snakes), are only represented by the single genus Sphenodon today. This taxon is often considered to represent a very conservative lineage.

Hominin palaeoecology in Late Pliocene Malawi : first insights from isotopes (13C, 18O) in mammal teeth [PDF]
, 2011 Carbon-13 and oxygen-18 abundances were measured in large mammal skeletal remains (tooth enamel, dentine and bone) from the Chiwondo Beds in Malawi, which were dated by biostratigraphic correlation to ca. 2.5 million years ago.

Dentin degradomics in dentin erosion
STOMATOLOGY EDU JOURNAL, 2022 Background Dentin degradomics are the enzymes found in dentin endogenously and are aimed at attacking organic compounds of the relevant tissue. During dentin demineralization, these enzymes could turn into the reaction phase and may step up the degradation. Thus, their connection with dentin erosion and tissue loss should be explained.

Hereditary dentine disorders: dentinogenesis imperfecta and dentine dysplasia [PDF]
Orphanet Journal of Rare Diseases, 2008 Abstract The hereditary dentine disorders, dentinogenesis imperfecta (DGI) and dentine dysplasia (DD), comprise a group of autosomal dominant genetic conditions characterised by abnormal dentine structure affecting either the primary or both the primary and secondary dentitions. DGI is reported to have an incidence of 1 in 6,000 to 1 in 8,000,
