Question · asked by 1 review
Orthodontic adhesive containing quaternary ammonium resin monomer + 40% n-ACP vs Conventional/control orthodontic adhesive (e.g., Transbond XT) or negative control: Calcium and phosphate ion release
- Population
- Human enamel specimens around orthodontic brackets (in vitro)
- Intervention
- Orthodontic adhesive containing quaternary ammonium resin monomer + 40% n-ACP
- Comparison
- Conventional/control orthodontic adhesive (e.g., Transbond XT) or negative control
- Outcome
- Calcium and phosphate ion release
In vitro, an n-ACP-containing adhesive significantly increased calcium and phosphate ion release up to 42 days in a single study (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.
