Efficacy of topical drug application to manage in-office bleaching sensitivity: a systematic review and meta-analysis of randomized clinical trials.
Synthesis in Clinical oral investigations, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectivesTo answer whether the topical drug application can reduce in-office tooth bleaching sensitivity without impairing the color change. MATERIALS AND
methodsThis review was registered on PROSPERO (CRD42024524171). Two reviewers screened PubMed, Web of Science, Scopus, Embase, and clinicaltrials.gov in March 2024 independently for randomized clinical trials investigating the efficacy of topical drug application to manage in-office tooth bleaching sensitivity. The risk of bias was assessed using Cochrane's Risk of Bias tool (RoB2). Certainty of the evidence was assessed using the Grading of Recommendations: Assessment, Development, and Evaluation tool (GRADE). The meta-analyses evaluated the bleaching sensitivity and color change with RevMan 5.4 software.
results334 articles were retrieved. The final sample was composed of four articles. Tested drugs were Otosporin, Eugenol, Ibuprofen with arginine, and Dipyrone. The meta-analysis evidenced no difference in bleaching sensitivity up to 1 h (MD, -0.39; 95% CI, -0.89, 0.11), 24 h (MD, -0.26, 95% CI, -0.71, 0.18), or 48 h (MD, 0.00, 95% CI, -0.16, 0.16). Meta-analysis for color change evidenced no difference for color change (MD, 0.03; 95% IC, -0.56, 0.61). The risk of bias was low. The certainty of the evidence was rated moderate for bleaching sensitivity and high for color change.
conclusionsAlthough topical drug application did not impair color change, it was ineffective in reducing in-office tooth bleaching sensitivity. CLINICAL RELEVANCE: topical drug application on dental enamel is not an effective approach in reducing bleaching sensitivity, but several modifications can be made in future studies to possibly achieve a better outcome.
