Abstract

Background: The aim of this study is to conduct an in-vitro assessment of the whitening efficacy and color reversals of various at-home whitening agents over a 14-day application period and one week post-treatment, devoid of any staining agents. Materials and Methods: This study established seven distinct groups for seven different at-home whitening agents. Eight teeth were randomly allocated to the groups and subjected to the specified whitening agents for a duration of 14 days. Subsequent to the whitening application, the teeth were kept in an artificial saliva environment until the subsequent application and throughout the conclusion of the first week post-treatment. Color measurements were performed with a digital spectrophotometer at baseline, on days 7 and 14, and at the conclusion of the 7th day following whitening. The acquired color change data were analyzed via the CIE2000 color system. Results: Upon completion of the whitening treatment, a significant and satisfactory whitening effect was evident in all groups, surpassing threshold values. The ΔE values for the groups from baseline to day 14 were as follows: P: 9.60; Z: 8.14; WP: 10.22; Op16: 10.43; Op10: 11.72; Op6: 5.81; B: 6.37. The baseline to week 1 post-whitening ΔE values were: P: 7.92; Z: 6.95; WP: 6.14; Op16: 5.46; Op10: 7.72; Op6: 4.26; B: 6.10. The ΔE values from day 14 to week 1 were as follows: P: 5.27; Z: 3.63; WP: 6.78; Op16: 6.84; Op10: 5.95; Op6: 2.12; B: 1.66. Conclusion: All at-home whitening agents used in the study produced a perceptible whitening effect that exceeded acceptable threshold values. The whitening efficacy of agents with comparable HP content was determined to be similar. It was determined that the whiteness acquired in the critical period of one week following bleaching treatment in HP-containing solutions was more stable.

Özet

Amaç: Farklı evde beyazlatma ajanlarının, herhangi bir renklendirici ajana maruz bırakılmadan 14 günlük beyazlatma uygulaması boyunca ve beyazlatma sonrası 1 haftanın sonunda beyazlatma performanslarının ve renk stabilitelerinin in-vitro değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Bu çalışmada, yedi farklı evde beyazlatma ajanı için toplamda yedi ayrı grup oluşturulmuştur. Dişler (n=8), gruplar arasında rastgele dağıtıldıktan sonra, 14 gün boyunca belirlenen beyazlatma ajanı ile tedavi edilmiştir. Beyazlatma uygulamasının ardından, dişler bir sonraki uygulamaya kadar ve beyazlatma sonrası birinci haftanın sonuna kadar yapay tükürük ortamında bekletilmiştir. Renk ölçümleri, dijital spektrofotometre aracılığıyla başlangıç değerleri, 7. ve 14. günlerde, ayrıca beyazlatma işlemi sonrasında 7. günün sonunda gerçekleştirilmiştir. Elde edilen renk değişim verileri, CIE2000 renk sistemi kullanılarak analiz edilmiştir. Bulgular: Beyazlatma tedavisinin sonunda tüm gruplarda algılanabilir ve kabul edilebilir eşik değerlerin üzerinde beyazlatma etkisi gözlenmiştir. Grupların başlangıç-14. gün ΔE değerleri ise sırasıyla P: 9,60; Z: 8,14; WP: 10,22; Op16: 10,43; Op10: 11,72; Op6: 5,81; B: 6,37 olarak; başlangıç-BS 1.hafta ΔE değerleri ise sırasıyla P: 7,92; Z: 6,95; WP: 6,14; Op16: 5,46; Op10: 7,72; Op6: 4,26; B: 6,10 olarak tespit edilmiştir. 14.gün- 1.hafta ΔE değerleri ise sırasıyla P: 5,27; Z: 3,63; WP: 6,78; Op16: 6,84; Op10: 5,95; Op6: 2,12; B: 1,66 olarak bulunmuştur. Sonuçlar: Çalışmada kullanılan bütün evde beyazlatma ajanlarıyla beyazlatma uygulamaları sonucunda algılanabilir ve kabul edilebilir eşik değerlerin üzerinde beyazlık sağlanmıştır. Eşdeğer HP içeriğe sahip evde beyazlatma ajanlarının sağladığı beyazlatma etkinliğinin birbirlerine benzer bulunmuştur. HP içerikli ajanlarda beyazlatma tedavisi sonrası 1 haftalık kritik dönemde elde edilen beyazlığın daha stabil olduğu sonucuna varılmıştır.
