Abstract

Amaç: Bu çalışmanın amacı belirli sürelerde
farklı içeceklerde bekletilen organik modifiye seramik (ormoser) ve
dimetakrilat-esaslı kompozit rezinlerin renk stabilitelerinin
karşılaştırılmasıdır.

Gereç ve yöntem: Bu çalışma için iki
farklı visközitede ormoser-esaslı kompozit rezinler (Admira, Admira Flow) ve
iki farklı dimetakilat-esaslı kompozit rezin (Valux Plus, Filtek Z250)
kullanıldı. Her bir kompozitten 2 mm kalınlığında ve 8 mm çapında 20 adet örnek
hazırlandı. Rastgele 4 gruba ayrılan örnekler üç farklı solüsyonda (kahve, pH
5,5; kola, pH 2,51 ve kırmızı şarap, pH 3,28) ve kontrol grubu olarak distile
suda (pH:6,7) bekletildi (n=5). Renk ölçümleri, örnekler solüsyonlarda
bekletilmeden önce ve bekletildikten 1, 7, 15 ve 30 gün sonra spektrofotometre
ile yapıldı ve ΔE değerleri hesaplandı. Verilerin istatistiksel analizinde tek
yönlü ANOVA ve Tukey LSD çoklu karşılaştırma testi kullanıldı. İstatistiksel
anlamlılık düzeyi p<0.05 olarak alındı.

Bulgular: Birinci gün sonunda yalnızca kırmızı
şarapta bekletilen Valux Plus ve Filtek Z250 örneklerinde ΔE>3,3 bulunurken
(p<0,05), 30 gün sonunda tüm örneklerde ΔE>3,3 bulundu. Tüm kompozitlerde
en yüksek renk farklılıkları kırmızı şarapta bekletilen örneklerde görülürken
(p<0,05), en yüksek ortalama renk farklılıkları Filtek 250 örneklerinde
tespit edildi.

Sonuçlar: Çalışmada kullanılan kompozit
rezinlerin farklı içecekler karşısında renk değişimine hassas olduğu bulunmuş,
ormoser-esaslı kompozit rezinler dışsal renklenmelere karşı daha dirençli
bulunmuştur.

Anahtar Kelimeler: Ormoser, dimetakrilat-esaslı kompozit rezin, renk strabilitesit  

 

COMPARISON
OF COLOR STABILITY OF ORMOCER AND DIMETHACRYLATE-BASED COMPOSITE RESINS AFTER IMMERSION
IN DIFFERENT BEVERAGES

ABSTRACT

 

Aim: The purpose of this study was to compare the color stability of organic
modified ceramic (ormocer) and dimethacrylate-based composite resin materials
after immersion in different beverages for a certain period.

Materials and method: Two different ormocer-based composite resin (Admira, Admira Flow) with
different viscosity and two dimethacrylate-based composite resin (Valux
Plus, Filtek Z250) were used in this
study. Twenty composite resin discs (8 mm x 2 mm) were prepared from each
material. Specimens were randomly divided into 4 groups and were immersed in
three staining solutions (coffee pH 5,5, cola pH 2,51, red wine pH 3,28) and distilled water for control group (n=5).
Color changes were measured with a spectrophotometer at baseline and after 1,
7, 15 and 30 days of immersion and ΔE values were calculated. Data were analyzed by using one-way ANOVA
and post-hoc Tukey LSD. A p-value <0.05 was considered statistically
significant.

Results: At the end of the first day, only in Valux Plus and Filtek Z250 samples
immersed in red wine showed a ΔE value > 3.3, while at the end of 30 days in
all samples ΔE was > 3.3. Among all drinks tested, maximal color change was
caused by red wine (p<0.05). The highest color differences were calculated
in Filtek Z250 samples (p<0,05).

Conclusions: It can be concluded that the tested composite
resin materials were susceptible to staining with different drinks and
Ormocer-based composite resins are more resistant to external discolorations.

Key words: Ormocer, Dimethacrylate-based composite,
