What is dentine similar to?

Dentine is similar to bone in that both are hard tissues composed of a mineralized matrix, primarily made up of collagen fibers and hydroxyapatite crystals. Additionally, like bone, dentine contains living cells; odontoblasts in dentine and osteocytes in bone. Both tissues also have the capacity for some level of remodeling and repair, although dentine's ability to regenerate is more limited compared to bone.
