Lactobacillus count (CFU/mL) · Children and/or adolescents (<18 years) without background systemic disease
Probiotics may make little to no difference to Lactobacillus count versus control (MD -0.78 CFU/mL, 95%CI -1.65 to 0.09; very low certainty).

Early childhood caries (ECC) · Children aged 6 years or younger (preschool children)
Serum 25(OH)D 50–75 nmol/l (vs ≥75 nmol/l) was associated with higher odds of ECC (OR 1.42; ungraded).

Enamel demineralization (QLF ΔF) · Human enamel specimens under cariogenic challenge (in situ / ex vivo)
Evidence on a synergistic effect of combining CO2 laser with fluoride versus fluoride alone is mixed: one ex-vivo study found combined treatment superior while another found no synergy (ungraded, 2 ex-vivo studies, no pooled estimate).

Dental caries prevalence · Brazilian children/adolescents in permanent dentition (BMI classified by WHO 2006 Z-score)
A meta-analysis of 2 studies (permanent dentition, WHO 2006 Z-score) was rated very low certainty; the pooled effect was not shown in the article.

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)
In the mandible, earlier Demirjian stage A-D (vs F-H) increases odds of space closure (OR 3.11; low certainty).

Salivary IL-8 level (pg/mL) · Children and young adults (3-25 years)
Salivary IL-8 levels are higher in children and young adults with active dental caries than in controls but the difference is not statistically significant (SMD 57.20 pg/mL, 95% CI -18.60 to 133.00; 7 studies); ungraded.
