Orthodontic treatment and oral microbiota changes: a systematic review of oral dysbiosis revealed by 16S rRNA gene analysis.

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: Evaluate the changes in oral microbiota linked to orthodontic treatment by analyzing the 16S rRNA gene. Materials and Methods: A total of 22 articles was included in the systematic review. The methodological quality of these studies was assessed using the Newcastle-Ottawa Scale for nonrandomized studies and the Risk of Bias tool for randomized studies. Results: Orthodontic appliances significantly influenced the composition of oral microbiota. Specifically, fixed orthodontic appliances were linked to an increase in periodontopathogenic bacteria associated with various systemic diseases. In contrast, transparent aligners correlated with an increase in Streptococcus species. Conclusions: In this study, we evaluated the changes in oral microbiota associated with orthodontic treatment by analyzing the 16S rRNA gene. Results revealed significant alterations in oral microbiota following orthodontic treatment; however, significant variability among studies prevents firm conclusions. Additional research is essential to clarify the effects on oral health.
