Remineralization / reduction in lesion severity (change in QLF, laser fluorescence, or lesion area) · Patients with white spot lesions / early caries lesions (WSLs/ECLs), including orthodontic and non-orthodontic lesions, active caries…
P11-4 plus fluoride varnish was significantly better than fluoride varnish alone (SMD -0.71, 95% CI -1.13 to -0.29); certainty of evidence not assessed (no GRADE).

Duration of orthodontic treatment during alignment stage · Adolescents and adults with malocclusion undergoing fixed orthodontic appliance treatment
It is very uncertain whether low level laser therapy (LLLT) changes duration of orthodontic treatment during alignment stage compared with conventional orthodontic appliance treatment (very low certainty).

Dental caries · Children (<19 years)
Children with vitamin D deficiency had a 22% higher risk of dental caries than those with normal vitamin D levels (unadjusted RR 1.22; ungraded).

Stability: Little's Irregularity Index (lower arch) · People who had received fixed appliance orthodontic treatment
Upper clear plastic retainer + lower fixed canine-to-canine retainer led to lower stability: Little's Irregularity Index (lower arch) compared with positioner; GRADE not reported.

Reduction in frequency and severity of drooling · Adults with Parkinson's disease and sialorrhea (drooling)
Type A botulinum toxin significantly reduced DSFS scores versus placebo (SMD -0.80, 95% CI -1.25 to -0.36; ungraded subgroup).

Overall success (composite of clinical and radiographic success) · Patients with carious pulp exposure in permanent teeth of mixed/unspecified root maturation
In mixed-maturation teeth, the effect of MTA versus calcium hydroxide on success is very uncertain (OR 1.11, 95% CI 0.17-7.11; very low certainty).

Tooth discoloration · Patients with carious pulp exposure in permanent teeth undergoing DPC or pulpotomy
More tooth discoloration was observed with MTA than with Biodentine, but odds ratios were implausibly large and not pooled (3 RCTs; ungraded).

Gingival inflammation-related index · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)
Short-term fluoride mouthwash has uncertain effects on gingival inflammation-related indexes versus blank control (very low certainty).

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.
