WebDentin located in the root walls of teeth that have been endodontically treated contains 9% less moisture than root dentin of vital teeth. 403 That is a positive feature for dentin adhesion. However, the area occupied by the more calcified transparent dentin in the root, also called sclerotic dentin, 404,405 widens with aging.

WebMicrobial invasion of dentin in caries triggers an adaptive response by odontoblasts, culminating in formation of a structurally altered reactionary dentin, marked by biochemical and architectonic modifications including diminished tubularity. WebIntracellular Ca2+ signaling engendered by Ca2+ influx and mobilization in odontoblasts is critical for dentinogenesis induced by multiple stimuli at the dentin surface. Increased Ca2+ is exported by the Na+–Ca2+ exchanger (NCX) and plasma membrane Ca2+–ATPase (PMCA) to maintain Ca2+ homeostasis. We previously demonstrated a functional …
