MMP-2 presence/activity · Human ex vivo carious dentin
MMP-2 shows no difference between root and coronal carious dentin; the evidence is very uncertain (very low certainty).
1 finding from 1 review
There is no difference in MMP-2 activity in root vs. coronal carious dentin; MMP-2 was present in both coronal and root dentin in all specimens (Toledano et al., 2010). The evidence is very uncertain.

Prevalence of white spot lesions (WSL) at debonding, subject level · Healthy adolescents and adults undergoing orthodontic treatment with fixed multi-bracket appliances
Fluoride varnish applied regularly during fixed orthodontic treatment may reduce the prevalence of white spot lesions at debonding (pooled RR 0.64, 95% CI 0.42 to 0.98), but the certainty of evidence is very low.
