Mean and SD of collagen degradation (%) of mineralized and treated human dentin explants after different storage times. Without (left), and with (right) addition of active MMP-2. 1a and 1b after 24 h; 1c and 1d after 1 wk; 1e and 1f after 3 wk.

AS: artificial saliva; MMP2: active metalloproteinase 2; CHX: digluconate chlorhexidine; MIN: mineralized dentin; PA: phosphoric acid demineralized dentin; EDTA: EDTA-demineralized dentin; SE: Clearfil SE Bond-treated dentin; XE: Xeno V-treated dentin.

The amount of ICTP liberated from the PA-demineralized dentin in the absence of chlorhexidine, and in the presence of active MMP-2 after 3 weeks was set to 100%, and the collagen degradation in the rest of the groups was calculated in each single experiment as a percent of this value.
