Aim: The aim of this in vitro study was to evaluate the effect of mouthrinses and thermocycling on the color stability of all-ceramic materials.
Materials and methods: A total of 100 all-ceramic samples with a thickness of 1.5 mm were prepared by applying dentin porcelain to the substructures within 0.5x10x10 mm dimensions. Color data were recorded with a spectrophotometer and color differences were calculated with CIEDE2000 formula. After baseline measurements (T0), the samples were equally divided into 2 groups (Group A and Group B). Samples in group A exposed to aging in a thermocycling device and color changes were recorded (T1). Groups were then divided into 5 subgroups (n:10) and the samples were immersed in Klorhex®, Listerine Total Care®, Tantum Verde®, Meridol® and distilled water for 12 hours. The last color changes were recorded (T2) and the color difference values (ΔE00) were statistically compared with the Kruskal-Wallis and Mann-Whitney U tests.
Results: Meridol® was statistically different from other mouthrinses except for Listerine Total Care® (p<0.001). Listerine Total Care® was statistically different from distilled water in both groups (p<0.05). In group A, the mean values in Meridol® were within the perceptible limits and Listerine Total Care® were within the acceptable limits (T0-T2). The mean values of mouthrinses in group B were below the perceptible limits (T0-T2). Thermocycling did not cause a statistically significant color difference (T0-T1).
Conclusion: Prolonged use of mouthrinses may cause color change in all-ceramic materials. Mouthrinses containing amine/stannous fluoride (Meridol®) should be recommended with caution for daily use.

Yaşlanma ve Ağız Gargaralarının Tam Seramiklerin Renk Stabilitesi Üzerine Etkisi

Öz

Amaç: Mevcut in vitro çalışmanın amacı, tam seramik malzemelerin renk stabilitesi üzerinde ağız gargaraları vetermal döngünün etkisini değerlendirmektir. Bulgular: MER’in renk farklılıkları, LIS dışında grup A ve grup B’deki diğer gargaralardan istatistiksel olarak farklı bulundu (p<0,001). LIS her iki grupta da DIS’den istatistiksel olarak anlamlı farklılık gösterdi (p<0.05). Grup A’da MER’deki ortalama değerler algılanabilir sınırlar içinde olup, LIS’deki ortalama değerler kabul edilebilir sınırlar içinde belirlendi (T0-T2). Grup B’de gargaraların ortalama değerleri algılanabilir sınırların (T0-T2) altında hesaplandı. Termal döngü ile yaşlandırma istatistiksel olarak anlamlı bir renk farklılığına (T0-T1) neden olmadı. Sonuç: Ağız gargaralarının uzun süreli kullanımı tam seramik malzemelerde renk değişikliğine neden olabilir. Amin/kalay florür içeren ağız garagaraları (MER) günlük kullanım için dikkatle önerilmelidir.
