- Effects of Ozonized Oil on At‐Home Tooth Bleaching: A Double‐Blind Randomized Clinical Trial Murilo Guimarães Campolina Lia Dietrich Julia Marques Martins Larissa Victoria Miranda Ubagai Guilherme José Pimentel Lopes Oliveira Ceci Nunes Carvalho Hugo Lemes Carlo Carlos José Soares Gisele Rodrigues Silva Journal of Esthetic and Restorative Dentistry ABSTRACT Objective This 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. Conclusions Overall, 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. 10.1111/jerd.70083 http://creativecommons.org/licenses/by/4.0/
