Deciphering the functions of Stromal Interaction Molecule-1 in amelogenesis using AmelX-iCre mice

Frontiers in Physiology, 2023
Introduction: The intracellular Ca2+ sensor stromal interaction molecule 1 (STIM1) is thought to play a critical role in enamel development, as its mutations cause Amelogenesis Imperfecta (AI).

Wear of human teeth: a tribological perspective [PDF]

, 2005
The four main types of wear in teeth are attrition (enamel-on-enamel contact), abrasion (wear due to abrasive particles in food or toothpaste), abfraction (cracking in enamel and subsequent material loss), and erosion (chemical decomposition of the tooth)

The Importance of Connexin 43 in Enamel Development and Mineralization

Frontiers in Physiology, 2018
During enamel development, formation of hydroxyapatite crystals and regulation of pH in the enamel matrix require massive transport of ions. Both ameloblasts and adjacent dental epithelial cells in the stellate reticulum co-express several transmembrane ...
