MMP-20 location/depth (outer vs inner) · Human ex vivo carious dentin

MMP-20 probably decreases in outer compared with inner carious dentin (moderate certainty).

Presence of host and bacterial-derived collagenolytic proteases in carious dentin: a systematic review of ex vivo… 2023 All outcomes
Ex vivo (extracted teeth / clinical carious or biofilm samples)
MMP-20 probably reduces in carious outer dentin when compared to carious inner dentin (moderate certainty); MMP-20 was significantly lower in outer dentin than inner (Shimada et al., 2009).

MMP-2 location/depth · Human ex vivo carious dentin

No clear direction of MMP-2 presence by lesion depth/location was found; the evidence is very uncertain (very low certainty).

Presence of host and bacterial-derived collagenolytic proteases in carious dentin: a systematic review of ex vivo… 2023 All outcomes
Ex vivo (extracted teeth / clinical carious or biofilm samples)
The evidence is very uncertain about the MMP-2 location in dentin, as no effect direction was found (MMP-2 ubiquitous and variable across regions).
