Turbid Dentin: This term refers to a zone of dentin
that has undergone significant degradation due to bacterial invasion. It is
characterized by:
Widening and Distortion of Dentin Tubules: The
dentinal tubules in this zone become enlarged and distorted as they fill
with bacteria.
Minimal Mineral Content: There is very little
mineral present in turbid dentin, indicating a loss of structural
integrity.
Denatured Collagen: The collagen matrix in this
zone is irreversibly denatured, which compromises its mechanical
properties and ability to support the tooth structure.
Implications for Treatment
Irreversible Damage: Dentin in the turbid zone cannot
self-repair or remineralize. This means that any affected dentin must be
removed before a restoration can be placed.
Restorative Considerations: Proper identification and
removal of turbid dentin are critical to ensure the success of restorative
procedures. Failure to do so can lead to continued caries progression and
restoration failure.
