ABSTRACT
Objective: The aim of this study was to evaluate the effects of different immersion solutions and denture cleansers on the color stability of acrylic and composite artificial teeth.
Methods: Maxillary anterior and premolar teeth in A2 color were used from 2 different types of artificial tooth materials (n = 8) in the study. After artificial teeth were kept in distilled water, cof- fee, and tea solutions at 37°C for 7 days, test specimens were immersed in distilled water, alkaline peroxide, and sodium hypochlorite denture cleansers. Color changes were measured by spec- trophotometer using the CIE L*a*b* system when specimens were obtained, after exposure to immersion solutions, and after washing with denture cleaners, then color differences (ΔE) were calculated. The obtained data were analyzed with the Student’s t-test, 2-way analysis of variance (ANOVA), 3-way ANOVA, and Bonferroni multiple comparison tests (P = .05).
Results: After being kept in immersion solutions, the highest ΔE values were observed in the composite artificial tooth specimens, and the highest color difference value was observed in the coffee solution group. There was no statistically significant difference between the denture cleansers in terms of the effect of the materials on the color change (P > .05).
Conclusion: While the most color difference was observed in the composite material among the artificial denture materials applied with cleaning solutions, there was no difference between the denture cleansers in terms of cleaning efficiency.
Keywords: Acrylic, artificial teeth, coloring, composite, denture cleansers

ÖZ
Amaç: Bu çalışmanın amacı; farklı daldırma ve protez temizleme solüsyonlarının akrilik ve kompo- zit yapay dişlerin renk kararlılığı üzerindeki etkilerini değerlendirmektir.
Yöntemler: Çalışmada iki farklı yapay diş materyaline ait A2 renginde maksiller anterior ve premo- lar dişler kullanıldı (n=8). Yapay dişler; distile su, kahve ve çay solüsyonlarında 37°C’de 7 gün süre ile bekletildikten sonra, distile su, alkalen peroksit ve sodyum hipoklorit protez temizleme solüs- yonlarına daldırıldı. Renk değişimleri, örnekler elde edildiğinde, daldırma solüsyonlarına maruz bırakıldıktan sonra ve protez temizleyicileri ile yıkandıktan sonra CIE L*a*b* sistemi kullanılarak spektrofotometre aracılığıyla ölçüldü ve renk farklılıkları (ΔE) hesaplandı. Elde edilen veriler stu- dent t-testi, iki yönlü ANOVA, üç yönlü ANOVA ve Bonferroni çoklu karşılaştırma testleri ile analiz edildi (P =0,05).
Bulgular: Daldırma solüsyonlarında bekletildiken sonra en yüksek ΔE değerleri kompozit yapay diş örneklerinde, en yüksek renk farkı değeri ise kahve solüsyonu grubunda gözlendi. Protez temizleme solüsyonları arasında, materyallerin renk değişimine etkisi açısından istatistiksel ola- rak anlamlı bir fark bulunmadı (P >0,05).
Sonuç: Temizleme solüsyonları uygulanan yapay diş materyalleri arasında en fazla renk değişimi kompozit materyalinde görülürken, temizleme solüsyonları arasında, temizleme etkinliği açısın- dan bir fark bulunmamıştır.
