1 · What the graph read from it

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.

2 · The registry

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

objectivesTo compare changes in tongue pressure during anterior open bite (AOB) treatment using a fixed palatal crib (PC) alone versus PC combined with brief orofacial myofunctional therapy (OMT), and to determine whether these changes predict overbite correction. MATERIALS AND

methodsThirty-two patients were divided into two groups: the PC group received a fixed palatal crib alone, while the PC-OMT group received PC plus weekly OMT sessions for the first two months. Lateral cephalometric radiographs and tongue pressure measurements using the Iowa Oral Performance Instrument (IOPI) were collected at baseline (T1) and after open bite correction or 12 months later when the appliance was removed (T2). Primary outcomes included changes in tongue pressure and overbite. Analysis of covariance (ANCOVA) controlled for initial open bite severity (p < 0.05). Linear regression analyzed the relationship between tongue pressure changes and overbite correction.

resultsEach group included 16 patients (PC: 3 males, 13 females; mean age 8.65± 0.93 years; PC-OMT: 9 males, 7 females; mean age 7.97 ± 1.00 years). Both groups showed similar overbite improvements. Tongue pressure increased in all variables across groups; however, swallowing pressure increased significantly less in the PC-OMT group. Changes in tongue pressure were not associated with overbite correction.

conclusionsTreatment with PC alone or combined with brief OMT yielded comparable overbite corrections. The addition of OMT moderated tongue pressure increases during swallowing. Changes in tongue pressure did not predict open bite correction in mixed dentition. CLINICAL RELEVANCE: Brief OMT combined with PC may reduce atypical swallowing post-crib removal, supporting long-term treatment stability.
