The radula is a distinctive, chitinous feeding apparatus found in most molluscs, and its specialised tooth structures play a crucial role in the efficient processing of food. In gastropods, the ...

New research reveals how genes inherited from Neanderthals and critical developmental markers like PITX2 influence tooth size, shedding light on human evolution and genetic diversity. Study: PITX2 ...

Researchers at the University of Zurich Center for Dental Medicine recently studied the Notch pathway’s role in the evolution of tooth morphology, with their results being published in Cellular and ...

Dental anthropology and morphology -- Description and classification of permanent crown and root traits -- Biological considerations : ontogeny, asymmetry, sex dimorphism, and inter-trait association ...

Result of principal component analysis (PCA) on tooth morphology in Baikal seals and its relative species. Horizontal axis represents principal component 1 and vertical axis represents principal ...

The interaction between genetics and tissue environment shapes how individual teeth form in different regions of the jaw. While most experimental studies have focused on mandibular (lower jaw) teeth, ...

Representative images and heatmaps illustrate how human fetal tooth germs from the upper and lower jaws, although morphologically similar at the cap stage, already display distinct gene expression ...

The toothlike structures represent a step toward bioengineered replacements for dental implants, say researchers behind the work. Lose an adult tooth, and you’re left with limited options that ...
