Question · asked by 1 review
Self etching primer (one-step etchant-and-primer technique) vs Conventional etchants (two-step etch and prime method using 37% phosphoric acid): Bond failure rate
- Population
- Children and adults with fixed orthodontic brackets bonded to incisors, canines and premolars
- Intervention
- Self etching primer (one-step etchant-and-primer technique)
- Comparison
- Conventional etchants (two-step etch and prime method using 37% phosphoric acid)
- Outcome
- Bond failure rate
Self etching primers (one-step etchant and primer system) showed no clear difference in bond failure rate compared with conventional etchants (two-step etch and prime method using 37%… (low certainty).

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.
