White spot lesion clinical score (mean values), subject level · Healthy adolescents and adults undergoing orthodontic treatment with fixed multi-bracket appliances
In a pooled analysis of two placebo-controlled trials, fluoride varnish also reduced white spot lesion clinical scores (pooled SMD -0.44, 95% CI -0.64 to -0.24); this secondary outcome was not separately GRADE-rated.

MMP-9 location/depth · Human ex vivo carious dentin
No clear direction of MMP-9 expression by lesion depth/location was found; the evidence is very uncertain (very low certainty).

Development of any (cavitated or non-cavitated) carious lesion · Children younger than 6 years with caries-free primary dentition (no cavitated or non-cavitated lesions at baseline)
Across the sample-based sensitivity analysis, mutans streptococci at baseline were associated with higher odds of developing caries.

DMFS (decayed, missing, filled surfaces) increment, occlusal surfaces · Schoolchildren aged 6-12 years with sound occlusal surfaces of the first permanent molars
Pit and fissure sealant and fluoride varnish showed no statistically significant difference in DMFS increment at 24 months (SMD -0.13, 95% CI -0.67 to 0.40; I2=92%; not GRADE-rated).

Mineral loss (transversal microradiography) · Enamel/dentin specimens with initial caries lesions (or sound surfaces) in intraoral (in situ) appliances worn by patients
Under remineralizing conditions, nHA produced significantly more remineralization than the negative control (MD 350, 95% CI 179 to 521; very low certainty).

Development of >=1 new carious lesion (caries incidence) · Children with caries-free primary first molars (with or without caries on other teeth), aged 1-5 years (paediatric clinic/dental school,…
Glass ionomer-based sealant may leads to lower development of >=1 new carious lesion (caries incidence) compared with no sealant (low certainty).
