Localization of matrix metalloproteinases (MMPs‐2, 8, 9 and 20) in normal and carious dentine

Abstract

The localization of MMPs was visibly detected using immunogold labelling. The localization of MMP-2 showed no significant difference among the three regions, while MMP-8 and MMP-9 showed significant reduction at the inner caries layer, and MMP-20 reduced toward the outer caries.
