Early extraction of a compromised first permanent molar vs Non-extraction (retained first permanent molar) or contralateral non-extraction side: Spontaneous space closure
- Population
- Children aged 5 to 15 years with a compromised first permanent molar
- Intervention
- Early extraction of a compromised first permanent molar
- Comparison
- Non-extraction (retained first permanent molar) or contralateral non-extraction side
- Outcome
- Spontaneous space closure
Early extraction of a compromised first permanent molar is followed by variable spontaneous closure of the post-extraction space (about 45.5% to 85.2% of cases); certainty was not GRADE-rated (Shekelle category III).

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.
