Abstract

Objective: The aim of this manuscript was to investigate the effect of carbon nanoparticles (CNs) addition into denture liners on the color change and water absorption and solubility.

Materials and Method: Test specimens (n=10) of Visco-Gel (Group VG) and Ufi-Gel (Group UG) were created either without (Groups C-as control and W) or with the incorporation of 0.5%, 1% and 10% CNs synthesized from licorice root plant. The size of the CNs were measured with dynamic light scattering. The color of each specimen was measured with a spectrophotometer. Water sorption and solubility were determined by weight measurement. The data were analyzed by two-way ANOVA for sample size estimation and Mann-Whitney U and Kruskal-Wallis tests for analyses of main outcomes with significance at the p<0.05 level.

Results: All CNs-added test groups showed statistically higher color change than control groups (p<0.0125). In Group UG, 10% CNs added test groups showed statistically higher water sorption and solubility values than Group C, W and 0.5% CNs added test groups (p<0.001). However, the addition of 0.5% and 1% CNs to Groups VG caused a statistical decrease in water sorption values compared to control groups and Group VG 10% (p<0.001).

Conclusion: Color change of CNs added denture liners were not within clinically accepted range of color difference regardless of addition rate. CNs addition in tested denture liners promoted changes in the liners’ sorption/solubility. UG was more prone to increase in both water sorption and solubility than VG.

Karbon nanopartikül ilave edilmiş iki tip protez astarının renk değişimi, su emilimi ve suda çözünürlüğü

Abstract

Amaç: Bu çalışmanın amacı, karbon nanopartikül (CN) ilavesinin protez astarlarının renk değişimi ve su emilimi ve sudaki çözünürlüğü üzerindeki etkisini araştırmaktır.

Gereç ve Yöntem: Visco-Gel (Group VG) ve Ufi-Gel (Group UG) nin disk şeklindeki örnekleri (n=10) CN ilave edilmeden (Grup C-kontrol ve W) veya %0.5, %1 ve %10 oranında Meyan kökü bitkisinden sentezlenen CN ilave edilerek hazırlandı. CN'lerin boyutu dinamik ışık saçılımı ile ölçüldü. Herbir örneğin rengi bir spektrofotometre (Analytik Jena, Specord 210 Plus, Jena, Germany) kullanılarak ölçüldü. Su emilimi ve suda çözünürlük ağırlık ölçümü ile belirlendi. Veriler örneklem büyüklüğü hesaplanması için çift yönlü ANOVA ve ana sonuçların analizi için Mann-Whitney U ve Kruskal-Wallis testleri ile p<0.05 düzeyinde anlamlı olacak şekilde analiz edildi.

Bulgular: Tüm CN eklenmiş test grupları, kontrol gruplarından istatistiksel olarak daha yüksek renk değişikliği gösterdi (p<0.0125). UG gruplarında, %10 CN eklenen test grupları, Grup C, Grup W ve %0.5 CN eklenen test gruplarından istatistiksel olarak daha yüksek su emilimi ve suda çözünürlük değerleri gösterdi (p<0.001). Bununla birlikte, Grup VG' ye %0.5 ve %1 CN ilavesi, kontrol gruplarına ve Grup VG %10'a kıyasla su emilimi değerlerinde istatistiksel olarak düşüşe neden oldu (p<0.001).

Sonuç: CN eklenen protez astarlarının renk değişimi, ekleme oranına bakılmaksızın klinik olarak kabul edilen renk farkı aralığında değildir. Test edilen protez astarlarına CN ilavesi, astarların su emilimi ve çözünürlüğünde değişikliklere neden olmuştur. UG, VG'ye göre hem su emilimi hem de suda çözünürlükte artışa daha yatkındır.
