Comparison of crevicular fluid cytokine levels after the application of surface sealants : A randomized trial.
Trial report in Journal of orofacial orthopedics = Fortschritte der Kieferorthopadie : Organ/official journal Deutsche Gesellschaft fur Kieferorthopadie, 2019. 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
purposeSurface sealants are widely used in orthodontic practice to avoid enamel decalcifications in patients treated with fixed orthodontic appliances. While their clinical benefit was tested in several studies, their biocompatibility has been evaluated to a lesser extent. Therefore, the aim of this randomized prospective study was to evaluate possible adverse biological effects of three commonly used surface sealants and a bonding primer on gingival tissues by analysing cytokines in crevicular fluid of orthodontic patients after the application of surface sealants.
methodsA single centre parallel trial was conducted. Using a split-mouth design quadrants of 15 patients requiring orthodontic treatment with fixed appliances were randomized to one of three commonly used surface sealants (Pro Seal®, Opal®Seal™, Protecto®CaF2Nano) and a bonding primer (Transbond™ XT). Interleukin (IL)-8 and IL-10 levels in crevicular fluids of the individual quadrants were assessed at four different time points (before application, and at 30, 60 and 90 min after application).
resultsIn all, 60 quadrants of 15 patients were randomized (Pro Seal® n = 15, Opal®Seal™ n = 15, Protecto®CaF2Nano n = 15, Transbond™ XT n = 15) and analysed. No significant changes for IL-8 or IL-10 levels in crevicular fluid after the application of surface sealants or bonding primer were detected. However, interpatient variability was high. No further clinical side effects were detected.
conclusionsCommonly used pre-bonding surface sealants (Pro Seal®, Opal®Seal™) do not appear to have a significant impact on inflammatory cytokines levels of crevicular fluid and do not appear to contribute to sensitization or hypersensitivity events.
