Prevalence of white spot lesions and risk factors associated with the COVID-19 pandemic.
Article in Journal of the World federation of orthodontists, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
backgroundThe objective of this study was to investigate the impact of the COVID-19 pandemic on the prevalence and persistence of white spot lesions (WSLs) among patients treated with traditional braces.
methodsA group of 434 consecutively finished cases who had pretreatment and post-treatment digital photographs taken were included in this study. Each set of photographs was evaluated by two investigators to determine prepandemic and postlockdown WSLs, in addition to changes in oral hygiene (OH) and other risk factors.
resultsThere was a statistically significant difference in the development of WSLs pre-COVID-19 lockdown (PRL) versus post-COVID-19 lockdown (POL) (P < 0.001). The overall prevalence for the development of WSLs increased to 52.8% POL. For patients with good pretreatment OH, the risk of developing WSLs POL (42.0%) was two times greater than the rate in PRL (20.1%). For patients whose OH worsened during treatment, 81.2% of POL patients developed WSL compared with 69.6% of PRL patients. The incidence of WSLs was statistically greater in the maxillary anterior region POL than PRL, whereas the incidence in the mandibular anterior region did not reach statistical significance. The distribution of WSLs was greater POL for each tooth irrespective of the arch.
conclusionsBecause of the COVID-19 pandemic, the prevalence of visible WSLs increased from 29.5% to 52.8%. Patients whose hygiene worsened during orthodontic treatment are at an increased risk of developing WSLs.
