Effects of Ozonized Oil on At-Home Tooth Bleaching: A Double-Blind Randomized Clinical Trial.
Trial report in Journal of esthetic and restorative dentistry : official publication of the American Academy of Esthetic Dentistry ... [et al.], 2026. 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
objectiveThis double-blind, randomized clinical trial evaluated the effect of ozonized sunflower oil on tooth sensitivity, color change, and patient perception during at-home bleaching with 10% hydrogen peroxide. CLINICAL CONSIDERATIONS: Forty participants were randomly assigned to receive ozonized or nonozonized sunflower oil, applied in trays for 1 min after each bleaching session (30 min daily for 21 days). Sensitivity was assessed daily using visual and numerical scales. Tooth color was measured at baseline, 1 week, and 1 month after treatment using a spectrophotometer (ΔEab, ΔE00, ΔWID) and a visual shade guide (ΔSGUs). Patient perception was evaluated through Likert-scale questionnaires.
conclusionsOverall, 72.5% of participants experienced sensitivity, with no significant difference in intensity (p = 0.536) or duration (p = 0.256) between groups. Color changes were similar (p > 0.05), although ΔEab and ΔE00 values decreased at 1 month (p = 0.010 and p = 0.026). Ozonized oil had an unpleasant taste (p = 0.002) and odor (p = 0.010). The use of ozonized sunflower oil did not reduce bleaching-related sensitivity or enhance whitening effectiveness, and its poor sensory properties may limit patient acceptance.
