That's good news. You might be interested in the article at this Link
. The title of the article is: MMP Activity in the Hybrid Layer Detected with in situ
Zymography. Here's a quote:
Since endogenous dentin MMPs are bound to collagen fibrils in mineralized dentin
(Mazzoni et al., 2009), acid-etching causes MMP exposure, and the subsequent
application of acidic monomers in etch-and-rinse or self-etch adhesives
increases the enzyme activity (Mazzoni et al., 2006; Nishitani et al., 2006;
Tay et al., 2006; De Munck et al., 2009; Osorio et al., 2011).
