Dental arch dimensional changes in deep bite adults treated with orthodontic fixed appliances in conjunction with maxillary incisor vs. canine bite turbos during the levelling and aligning phase: a randomized clinical trial.

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
introductionThis randomized clinical trial compared arch dimensional changes, dentoskeletal changes, and the rate of overbite correction in deep bite adults treated with fixed appliances and either maxillary incisor bite turbos (IBT) or canine bite turbos (CBT). MATERIALS AND
methodsForty-six deep bite subjects treated with fixed appliances were randomized into IBT (n = 23) and CBT (n = 23) groups. Changes in intercanine width (ICW), arch height (AH), and Little's Irregularity Index (LII) were analyzed from before treatment (T
resultsIn both groups, mandibular ICW, and maxillary and mandibular AH significantly increased while maxillary and mandibular LII decreased. Maxillary and mandibular incisor proclination and molar extrusion were observed. The IBT group showed significantly greater changes in mandibular ICW, maxillary and mandibular AH, and mandibular incisor proclination than the CBT group. However, the overbite correction rate and the LII reduction were not significantly different between the groups.
conclusionsThe IBT and CBT produced similar effects on arch dimensions and dentoskeletal changes. However, the IBT group demonstrated greater arch dimensional changes. CLINICAL RELEVANCE: Clinicians may consider IBT if flaring incisors is desired. Alternatively, CBT is better for cases with limited incisor proclination and where minimizing arch dimension change is needed, such as in narrow ridge situations. CLINICAL
