Correction of Supernumerary Tooth-Associated Anterior Crossbite in Mixed Dentition Using a 2 × 4 Appliance.

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
Anterior crossbite is a common tooth alignment discrepancy seen among the paediatric population especially during the mixed dentition stage. There are many causes of anterior crossbite, and the presence of supernumerary tooth/teeth is one of them. Early interceptive intervention is essential to avoid the need for more complex orthodontic treatment later. This case report describes the management of a 10-year-old child who presented with anterior crossbite involving Teeth 21 and 31, leading to gingival recession of Tooth 31. The crossbite malocclusion was associated with a supernumerary tooth in the upper incisor region. Extraction of the supernumerary tooth was performed, and correction of the anterior crossbite was commenced with a 2 × 4 appliance. Adequate stability with a positive overjet was observed at the 6-month review. The 2 × 4 orthodontic appliance may be considered a treatment option for correcting anterior crossbite in patients with poor compliance with removable appliance therapy.
