Geçici restorasyon materyallerinin yüzey aşınmalarının değerlendirilmesi

Amaç: Bu çalışmanın amacı, üç farklı geçici restorasyon materyalinin yüzey aşınma davranışlarının karşılaştırılmasıdır. Gereç ve Yöntem: Çalışma, üç grup (grup PM: Polimetil metakrilat; grup PE: Polietil metakrilat, grup BİS: Bis-akril kompozit rezin) ve toplam 60 adet örnekten (n=20) oluşmaktadır. Aşınma testi için çiğneme simülasyon cihazı kullanılmış olup, örnekler 10000,20000 ve 30000 devirlerde teste tabi tutulmuştur (5-55°C, termal siklus). Örnek yüzeylerinde oluşan aşınma miktarının belirlenmesinde temassız optik profilometre kullanılmıştır. Verilerin istatistiksel olarak değerlendirilmesinde Shapiro-Wilk, iki yönlü varyans analizi ve Tukey testleri ile Univariate yönteminden yararlanılmıştır (p

Evaluation of surface wear of provisional restorative materials

behavior of three different provisional restorative materials. Materials and Method: The study consists of three groups (group PM: Polymethyl methacrylate; group PE: Polyethyl methacrylate, group BIS: Bis-acryl composite resin) and a total of 60 samples (n = 20). A chewing simulator was used for the wear test and the samples were subjected of 10000, 20000 and 30000 cycles (5-55°C, thermocycling). Non-contact optical profilometer was used to determine the amount of wear on the sample surfaces. Shapiro-Wilk, two-way analysis of variance and Tukey tests and Univariate method were used in the statistical analysis of the data (p
