Özet
Background: The aim of this study was to compar e the color stability of two differ ent univer sal shade composite r esins after coffee staining and bleaching with 40% H?O?. Methods: Restor ations (Depth: 2 mm and Diameter: 8 mm) wer e per for med using Omnichr oma (BO) and Essentia Univer sal (LE) composite r esins on the buccal and lingual sur faces of 10 r emoved car ies-fr ee molar s, using selective etching and a univer sal adhesive. CIE L*, a*, b* values wer e per for med on the initial, 1st, 6th, and 12th days of immer sion in coffee and after 40% H?O? bleaching agent using a spectr ophotometer . V alues of ?E<inf>00</inf>, ?L?, ?C?, and ?H? wer e calculated using the CIEDE2000 for mula. Mann-Whitney U test was used to compar e ?E<inf>00</inf>, ?L?, ?C? and ?H? values accor ding to the mater ials. Gener al Linear Model V ar iance Components test was used to deter mine the effect of ?L?, ?C? and ?H? values on ?E<inf>00</inf> values (p<0.05). Results: The ?E<inf>00</inf> and ?L' values for BO and LE mater ials wer e not statistically significant (p>0.05). After bleaching, ?L' and ?C' wer e shown to be effective for both BO and LE in T<inf>a</inf> measur ements, wher eas ?H' was ineffective. Conclusion: Within the limitations of this study, it was found that BO and LE mater ials stained to clinically unacceptable levels, while bleaching pr ocedur es showed good effectiveness r esults on both mater ials. © 2025, Selcuk University.
