Changes in glenoid fossa of adult female patients with Class II division 1 malocclusion during premolar extraction treatment and mini-implant anchorage: a cone-beam computed tomography 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
Objectives: To evaluate changes in glenoid fossa morphology before, during, and after orthodontic treatment with extractions. Materials and Methods: Eighty-four cone-beam computed tomograms from 28 adult female patients with Angle Class II, division 1 malocclusion, who underwent orthodontic treatment involving premolar extraction and mini-implant insertion, were collected at three time points: before treatment (T0), during treatment (just before extraction space closure, T1), and after treatment (T2). Changes in the morphology of the glenoid fossa and the relationship of the anterior teeth among T0, T1, and T2 were recorded. Results: Inclination of the articular eminence (AEI-BFL and AEI-TRL) increased from T1 to T2 and from T0 to T2, whereas the width of the glenoid fossa (GFW) decreased from T1 to T2 and from T0 to T2. Changes in depth of the glenoid fossa (GFD) and the ratio of GFW to GFD were observed only in T0-T2. The height of the articular eminence (AEH) showed no significant differences among the three time points. Except for incisor overbite, which decreased from T0 to T1 and then to T2, all other dental parameters showed differences only in T1-T2 and T0-T2. Conclusions: Orthodontic treatment with extractions can induce adaptive morphological changes in the glenoid fossa, primarily during the stage of extraction space closure. These changes are mainly characterized by a steeper AEI and a reduction in GFW.
