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).
