Bulk-fill composite resin with 7-second dentine etching vs Bulk-fill composite resin with 15-second dentine etching: Treatment failure (annual failure rate)
- Population
- Children (aged 5-8 years) with Class-II caries in primary molars, no pulp therapy
- Intervention
- Bulk-fill composite resin with 7-second dentine etching
- Comparison
- Bulk-fill composite resin with 15-second dentine etching
- Outcome
- Treatment failure (annual failure rate)
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).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
