Effect of zinc oxide nanoparticles on the flexural strength of polymethylmethacrylate denture base resin

Öz:

This study evaluated the flexural strength of polymethyl methacrylate (PMMA)reinforced with various concentrations of zinc oxide (Zn O) nanoparticlesMaterials and MethodsNano ZnO was added in 0, 0.4, 0.6, 0.8, 1.2 and 1.4 percentage to PMMA denturebase material. 60 specimens of heat cure polymerizing acrylic resin of dimensions10mm x 4mm x 80mm were fabricated in accordance to ISO 20795-1-2013. Thespecimens were divided into 6 groups. Acrylic specimens were processed accordingto manufacturer’s instruction. Three-point bending test was performed to evaluatethe flexural strength. Surface analysis was performed with scanning electronmicroscopy (SEM) to observe the fracture surfaces of specimens. ANOVA and Tukeytests were used for the statistical analysis (p < 0.05).ResultsStatistical analysis revealed significant differences in strength between groups. Theflexural strength improved with the addition ZnO nanoparticles. Highest meanvalue was observed in Group nZn -14 (91.31 MPa) and lowest in control GroupnZn-0 (61.36 MPa). ANOVA and Tukey’s honestly significance test found statisticalsignificant differences among the groups ( p<0.001).ConclusionThe addition of ZnO nanoparticles in all concentrations increased the flexuralstrength of acrylic resin when compared to the control group.

Çinko Oksit nanopartiküllerinin Polimetilmetakrilat protez kaidelerinin bükülme direncine etkisi. Amaç: Bu çalışmada, farklı konsantrasyonlarda çinko oksit (Zn O) nanopartkülleriyle güçlendirilmiş polimetilmetakrilatın (PMMA) bükülme direnci değerlendirilmiştir. Gereç ve yöntem: Nano Zn O yüzde 0, 0.4, 0.6, 0.8, 1.2 ve 1.4 oranlarda PMMA protez kadie materyaline ilave edilmiştir. ISO 20795-1-2013 standardına uygun olarak 10mm x 4mm x 80mm boyutlarında 60 adet ısı ile polimerize olan akrilik örnek hazırlanmıştır. Örnekler, 6 gruba bölünmüştür. Akrilik örnekler üreticinin önerileri doğrultusunda hazırlanmıştır. Bükülme direncinin ölçümü için 3 nokta eğme testi uygulanmıştır. Örneklerin yüzeylerindeki kırılmaları tespit etmek için yüzey analizi scanning electron microscobu(SEM) ile gerçekleştirilmiştir. İstatistiksel analiz için ANOVA and Tukey testleri kullanılmıştır (p<0.05). Bulgular: İstatistiksel analiz gruplar arasında anlamlı değişiklikler göstermiştir. Zn O nanopartküllerinin ilavesi bükülme dayanuımını arttırmıştır. En yüksek ortalama değer nZn -14 (91.31 MPa) ve en düşük değer control grubu nZn-0 (61.36 MPa) de bulunmuştur. ANOVA and Tukey testleri gruplar arası farklılıklar tespit etmiştir (p<0.001). Sonuç: Zn O nanopartküllerinin ilavesi her konsantrasyonda control grubuna göre akrilik rezinin bükülme direncini arttırmıştır. Klinik sonuç: PMMA’ın çinko oksit nanopartkülleriyle güçlendirilmesi protezlerin bükülme direncini arttırabilir.
