The laryngeal mask airway in the extraction of supernumerary teeth in children: a retrospective study.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis study aims to evaluate the safety, efficacy, and complications associated with the use of the laryngeal mask airway (LMA) in pediatric patients undergoing supernumerary tooth extraction, to evaluate and explore its application in outpatient pediatric dental surgery. MATERIALS AND
methodsA retrospective analysis of pediatric patients who underwent supernumerary tooth extraction under general anesthesia with LMA between 2021 and 2025. Data collected included patient demographics (age, sex, body mass index, medical history), surgical duration, LMA size, incidence of ventilation failure, immediate adverse airway events, and delayed airway injuries.
resultsA total of 529 patients were included. The final success rate was 514 cases (97.16%). The success group comprised patients with successful initial ventilation following induction and stable ventilation throughout the surgical procedure. The failure group was a composite population including patients with failure of LMA insertion during induction and failure of intraoperative ventilation maintenance. Risk factors for LMA failure included high body mass index (BMI), micrognathia, and prolonged surgery. The incidence of laryngospasm was 0.38%, and postoperative sore throat occurred in 1.32% of patients. No regurgitation, aspiration, or bronchospasm was observed.
conclusionsThe LMA achieved a 97.16% success rate in outpatient pediatric supernumerary tooth extractions. LMA‑related adverse airway events and injuries were rare, indicating that the LMA is a safe and effective airway management device for pediatric dental surgery. CLINICAL RELEVANCE: The LMA is a safe and effective airway management tool with a high success rate and rare adverse events for outpatient pediatric supernumerary tooth extraction, identifying high BMI, micrognathia, and prolonged surgery as risk factors for LMA failure, which is clinically relevant for optimizing such procedures.
