Noncollagenous proteins are part of dentin's organic matrix.

Explanation:
Dentin’s organic matrix is not just a collagen scaffold; it also includes noncollagenous proteins produced by odontoblasts. These proteins—such as dentin phosphoprotein, dentin sialoprotein (part of the DSPP family), dentin matrix protein 1, and others—remain within the mineralized dentin and play key roles in regulating mineral deposition, crystal growth, and the overall properties of dentin. They interact with collagen fibrils to guide mineralization and help determine dentin’s hardness and resilience. Because noncollagenous proteins are a recognized component of the dentin organic matrix, the statement is true.
