Which collagen type is predominant in the dentin matrix?

Explanation:
The organic framework of dentin is dominated by type I collagen, which forms the fibrillar network that serves as the scaffold for mineral deposition. This collagen provides the tensile strength and structural framework necessary for hydroxyapatite crystals to align and grow within the matrix. Type II collagen is mainly found in cartilage, and type IV forms basement membranes, so they are not the primary components of dentin. Dentin does include non-collagenous proteins, but they do not comprise the main organic matrix. Thus, type I collagen is the predominant collagen in the dentin matrix.
