Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Discuss the Rationale for Minimally Invasive Endodontics and the Merits and Demerits of the Concept

Australian Endodontic Journal, EarlyView.
ABSTRACT Minimally invasive endodontics (MIE) places emphasis on the conservation of sound tooth structure and viable pulp tissue during endodontic procedures such as root canal treatment (RCTx) and vital pulp therapy (VPT). The use of minimal access cavity designs and conservative canal preparation dimensions have been investigated as a way to improve
