Abstract

Background: To evaluate the mechanical and surface properties of two glass ionomer restorative systems (EQUIA Fil, Ionostar Molar) and a resin composite (Charisma Classic) after thermocycling. Methods: Twenty disk-shaped samples were prepared from each material in teflon molds according to manufacturer’s instructions. After the samples were stored in distilled water at 370C for 24 h, microhardness and surface roughness measurements were performed from each group and repeated after 5000 and 10000 thermocycling. Scanning electron microscopy examinations were also performed. The data were analyzed by using Wilcoxon signed rank and Bonferroni corrected multiple comparison tests. Results: EQUIA did not exhibit significant differences in its microhardness values after thermocycling (p>0.005). In contrast, Ionostar Molar and Charisma Classic exhibited statistically significant decreases in baseline microhardness after 5000 and 10000 thermocycling processes (both p0.05). However, a statistically significant increase was observed after 10000 thermocycles for both of these two materials (p=0.002 and p

Özet

Amaç: İki cam iyonomer restoratif sistem (EQUA Fil, Ionostar Molar) ve bir kompozit rezinin ısıl döngü ile yaşlandırma sonrası mekanik ve yüzey özelliklerini değerlendirmektir. Gereç ve Yöntemler: Her materyalden 20 adet örnek üretici firma talimatları doğrultusunda hazırlandı. Örnekler 370C’de 24 saat bekletildikten sonra, mikrosertlik ve yüzey pürüzlülük ölçümleri yapıldı ve bu ölçümler 5000 ve 10000 ısıl döngü sonrasında tekrarlandı. Her gruptan bir örnek yüzey değerlendirmesi için taramalı elektron mikroskobisi ile incelendi. Veriler Wilcoxon signed rank testi ve Bonferroni düzeltmeli çoklu karşılaştırma testi kullanılarak analiz edildi. Bulgular: EQUIA, ısıl döngü sonrası mikrosertlik değerlerinde anlamlı bir farklılık göstermedi(p>0.005). Ionostar Molar ve Charisma Classic gruplarında başlangıç mikrosertlik değerlerine göre 5000 ve 10000 ısıl döngü sonrası anlamlı azalma gözlendi (p0.05). Bununla beraber, her iki materyalde de 10000 döngü sonrası yüzey pürüzlülük değerlerinde anlamlı bir azalma tespit edildi (p=0.002, p
