Transverse maxillary dimensions and upper airway morphology in mouth- and nasal-breathing children aged 10-12 years: A CBCT-based study.

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
Introduction: Mouth breathing (MB) is a dysfunctional respiratory pattern that may affect craniofacial development by altering maxillary arch width and upper pharyngeal airway morphology. Early identification is critical to prevent long-term dentofacial and airway complications. This study aimed to compare maxillary arch width and upper airway morphology between mouth- and nasal-breathing children aged 10-12 years using Cone Beam Computed Tomography (CBCT). Materials and methods: In this cross-sectional study, 30 children (15 mouth breathers and 15 nasal breathers) underwent CBCT imaging. Transverse maxillary arch dimensions were measured at four points: maxillary width at molars (MWM), intermolar width (IMW), maxillary width at canines (MWC), and intercanine width (ICW). Upper airway morphology was assessed using volumetric (nasopharyngeal volume [NPV], oropharyngeal volume [OPV]) and cross-sectional area (nasopharyngeal area [NPA], oropharyngeal area [OPA]) measurements. Independent Results: The MB group showed significantly reduced maxillary arch widths (MWM, IMW, MWC, ICW) and diminished upper airway volume and area (NPV, OPV, NPA, OPA) compared to nasal breathers ( Conclusion: Mouth breathing in school-aged children is associated with measurable reductions in maxillary arch width and upper pharyngeal airway dimensions.
