Bilateral extraction of compromised mandibular first permanent molars vs Age- and gender-matched non-extraction controls: Lower incisor inclination (lingual tipping and retrusion)
- Population
- Children (approximately 11 years or older) with compromised mandibular first permanent molars
- Intervention
- Bilateral extraction of compromised mandibular first permanent molars
- Comparison
- Age- and gender-matched non-extraction controls
- Outcome
- Lower incisor inclination (lingual tipping and retrusion)
Bilateral lower first permanent molar extraction was associated with lingual tipping and retrusion of the lower incisors in one case-control 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.
