Dentin organic component is predominantly which?

Explanation:
The organic matrix of dentin is dominated by collagen, specifically type I collagen, which forms the fibrous scaffold that the mineral crystals deposit onto. This collagen network makes up the vast majority of the organic component—about 85%—providing a flexible framework that gives dentin its toughness and acts as a template for mineralization. The remaining organic material consists of noncollagenous proteins (such as dentin phosphoproteins and proteoglycans) in smaller amounts, which play roles in mineralization and matrix organization. Water is a separate component and is not part of the organic matrix. So, the key idea is that collagen is the predominant organic component of dentin.
