Sleep-Disordered Breathing and Dimensions of The Maxillary Dental Arch and Hard Palate in Children With Class II and Large Overjet-A Case-Control Study.
Trial report in Journal of oral rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04964830 (Sleep, Upper Airway and Dental Occlusion in Children With Large Overjet Before and After Treatment With a Mandibular Advancement Device), which is not on this 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.

Abstract
backgroundClass II occlusion is associated with narrow dimensions of the maxillary dental arch and hard palate (maxillary dimensions), which may increase the risk of narrow upper airways and sleep-disordered breathing (SDB).
objectivesThe aim was to compare maxillary dental arch and hard palate dimensions in children with Class II and large overjet ≥ 6 mm (study group) to a control group with neutral occlusion and to examine the relation between SDB and maxillary dimensions.
methodsThe study group included 37 children (19 boys; 18 girls; median age 12.3 years) and the control group included 32 children (16 boys; 16 girls; median age 12.2 years). SDB was assessed by respiratory polygraphy, the distances between maxillary canines and first permanent molars were measured by intraoral scans and the general relation between SDB and maxillary dimensions was analysed.
resultsSignificantly smaller distances between both canines and first molars (p ≤ 0.001) were found in the study group. No significant differences in dimensions of the hard palate or SDB were found between the groups but the snore index tended to be higher in the study group (p = 0.051). No general significant associations between SDB measurements and maxillary dimensions were found in the total group of participants.
conclusionsSignificantly reduced transversal dimensions of the maxillary dental arch were found in the study group with Class II occlusion compared to controls. No significant difference regarding dimensions of the hard palate or SDB between the groups was found nor between SDB and maxillary dimensions. However, intraoral scans may be useful in risk assessment of early signs of paediatric SDB in orthodontic patients.
