Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
Composite resin (hybrid 0-19.5%; bulk-fill 0-16.9%) performed comparably to or better than most alternatives across 11 RCTs; evidence is of low to unclear quality (ungraded).
1 finding from 1 review
Not applicable (no eligible studies) · Children with carious primary teeth (no pulp therapy)
No eligible RCTs assessed new bio-active restorative materials in carious primary teeth; this is an evidence gap identified by the review.

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
Glass carbomer had very high failure rates (up to 46.2%) in a single RCT, far worse than composite resin or RMGIC; low quality of evidence (ungraded).

Quantitative light-induced fluorescence (QLF) change · Patients with early caries lesions in permanent teeth (non-fluoridated water area)
Adding CPP-ACP to fluorides did not significantly change QLF outcomes for smooth-surface early caries lesions versus fluorides alone; not GRADE-rated.
1 finding from 1 review
Visual inspection scores · Patients with early caries lesions in permanent teeth (non-fluoridated water area)
Two trials reported visual inspection scores but could not be pooled (different criteria, missing standard deviations) and gave inconsistent findings, so no quantitative conclusion could be drawn.

Laser fluorescence (LF) change · Patients with early caries lesions in permanent teeth (non-fluoridated water area)
For occlusal early caries lesions, adding CPP-ACP to fluorides produced significantly greater laser-fluorescence improvement than fluorides alone (favors the combination); not GRADE-rated.

Total lesion area divided by total surface area (visual) · Patients with early caries lesions in permanent teeth (non-fluoridated water area)
Adding CPP-ACP to fluorides did not significantly change the lesion-area outcome for smooth-surface early caries lesions versus fluorides alone; not GRADE-rated.

MMP-2 expression/activity · Human ex vivo carious dentin (head/neck radiotherapy)
MMP-2 showed no difference between irradiated and non-irradiated carious dentin (one study; ungraded).
1 finding from 1 review
No significant difference in MMP-2 (gelatinase) expression or activity between irradiated and non-irradiated groups (Gomes-Silva et al., 2017a); GRADE not separately applied to this comparison.
