What is the calcification percentage of dentin?

Dentin is composed of a significant percentage of mineral content, primarily hydroxyapatite, along with organic materials and water. The calcification percentage of dentin is typically around 70%. This means that 70% of dentin's composition is mineralized, contributing to its hardness and structural integrity, which enable it to support the enamel above it and withstand functional stresses during chewing.

Understanding this calcification level is crucial for dental professionals because it impacts how dentin reacts to various treatments, including restorative procedures and the application of certain dental materials. Moreover, a dentin structure that is less than fully calcified can have implications for the health and durability of restorative work, as well as sensitivity issues in patients.
