MMP-13 presence/activity · Human ex vivo carious dentin
MMP-13 may be increased in root compared with coronal carious dentin, but the evidence is very uncertain (very low certainty).

Future caries experience (dmft/dmfs) · Children younger than 6 years with caries-free primary dentition (no cavitated or non-cavitated lesions at baseline)
Children with mutans streptococci at baseline had a greater future caries experience (SMD 0.85, a large effect; ungraded).

Continued root formation / root development · Patients with carious pulp exposure in permanent teeth (predominantly immature) undergoing DPC or pulpotomy
Evidence on continued root formation for calcium hydroxide versus MTA is weak and inconclusive (3 RCTs, not pooled; ungraded).

Cathepsin B (CT-B) presence/activity · Human ex vivo carious dentin (mostly coronal), natural caries lesions
Cathepsin B may be increased in carious dentin compared with sound dentin, but the evidence is very uncertain (very low certainty).
1 finding from 1 review
CT-B may be increased in carious dentin when compared to sound dentin, but the evidence is very uncertain (Vidal et al., 2014; Nascimento et al., 2011: significantly higher in caries, p<0.05).

Predictive performance for coronal caries increment (positive likelihood ratio, LR+) · Children and adolescents (aged 2-19) at risk of coronal caries increment (caries onset or progression)
Most externally validated coronal-caries models showed modest LR+ (<5); only Campus 2012 and Gao 2013 NUS-CRA reached the useful threshold; no pooled estimate; ungraded.

Multivariable prediction models of caries increment: a systematic review and critical appraisal. 2023 All outcomesFollow-up >=1 year (included studies 1-5 years) · Oral health care; children/adolescents; no geographical restriction · Model validation studies
No meta-analysis. Per-model LR+ (Table 2) across the 9 validation studies (31 coronal models) ranged roughly 0.78-5.53 (e.g. Beck 1.62-3.00, Christian/CAMBRA 1.09-1.14, Gao 2013 CAT ~1.03 to NUS-CRA 5.31, Campus 5.53,…
