Question · asked by 1 review
Extraction at patient age <8 years vs Extraction at patient age >10 years: Spontaneous space closure
- Population
- Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)
- Intervention
- Extraction at patient age <8 years
- Comparison
- Extraction at patient age >10 years
- Outcome
- Spontaneous space closure
In the mandible, extraction before age 8 (vs after 10) increases odds of space closure (OR 5.01; 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.
