Treatment failure (annual failure rate) · Children (aged 5-8 years) with Class-II caries in primary molars, no pulp therapy
Etching dentine for 7 s rather than 15 s lowered bulk-fill composite failure (5.8% vs 16.9% annual failure) in one RCT; low quality of evidence (ungraded).

Caries lesion initiation/progression (ICDAS score, laser fluorescence/DIAGNOdent, photographic pixels, enamel acid resistance) · Patients (children and adults, age 3-40 years) with initial enamel caries lesions (non-orthodontic and orthodontic)
No meta-analysis was possible for the 5 in vivo RCTs (high heterogeneity); narratively nHA showed generally no significant difference versus fluoridated dentifrice, and the evidence was not graded (ungraded).

Caries prevalence in permanent dentition · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)
A primary-dentition DMFT over 13 is associated with about 15 times higher risk of caries in permanent teeth (single study; not GRADE-rated).

Caries arrest · Children (age 1-10 years) with active cavitated dentin caries lesions in primary molars
38% SDF arrested more caries than 12% SDF (pooled ES 0.37, 95% CI 0.27-0.47; single study; ungraded).

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
Metal-reinforced GIC had a high annual failure rate (29.9%) in a single RCT; low quality of evidence (ungraded).
