Selective caries removal (SCR) + composite resin vs Complete caries removal (CCR) + composite resin

Treatment failure (annual failure rate) · Children with deep dentine caries in primary molars restored with composite resin (indirect pulp treatment; pulpotomy only if pulp exposed…

Complete caries removal with composite resin had an annual failure rate of 6.8% in primary molars (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

Bulk-fill composite resin with 7-second dentine etching vs Bulk-fill composite resin with 15-second dentine etching

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).

Hall technique vs Compomer restoration or non-restorative caries treatment

Treatment failure (annual failure rate) · Children (aged 3-8 years) with 2-surface occluso-proximal dentine caries in primary molars, no pulp therapy

Preformed metal (Hall) crowns had a low reported annual failure rate (3.1%) versus compomer (14.7%) in one RCT; low quality of evidence (ungraded).

Composite resin with etch-and-rinse (total-etch) adhesion vs Composite resin with self-etch adhesion (same universal adhesive)

Treatment failure (annual failure rate) · Children with moderately deep dentine caries in primary molars, no pulp therapy

Etch-and-rinse adhesion failed more than self-etch (19.5% vs 7.0% annual failure) in one RCT; low quality of evidence (ungraded).
