Nanodoldurucu içeren beş farklı kompozitin yüzey sertliği ve pürüzlülüğü açısından değerlendirilmesi

Year 2014, Volume: 1 Issue: 2, 43 - 48, 01.08.2014

Abstract

Amaç: Bu çalışmanın amacı bir nanofil (Filtek Supreme XT) ve dört
nanohibrit kompozitin (İvoclar Tetric EvoCeram, Dentsply Ceram X,
Voco Grandio, Bisco Ælite) polisaj sonrası yüzey sertliklerini ve
pürüzlülüklerini değerlendirmektir.
Gereç ve Yöntemler: Her test için her bir kompozitten on adet
örnek hazırlandı ve üreticilerin talimatları doğrultusunda şeffaf bant
altında polimerize edildi. Polimerizasyondan sonra tüm örnekler
OptiDisc polisaj diskleri ile 10’ar sn polisajlandı. Yüzey sertliğinin
değerlendirilmesinde Vicker’s sertlik testi ve yüzey pürüzlülüğü için
ise yüzey profilometre testi kullanıldı. İstatistiksel analizde her test
için örneklerin üç farklı bölgesinden elde değerlerin ortalamaları
kullanıldı.
Bulgular: Kompozitler arasında yüzey sertliği ve pürüzlülüğü
açısından istatistiksel olarak anlamlı farklılıklar bulundu. En yüksek
yüzey sertliği değeri Grandio ve Supreme XT gruplarından elde
edilirken, en düşük yüzey pürüzlülüğü değeri Supreme XT
grubundan elde edildi.
Sonuç: Bu bilgiler ışığında kompozit rezin seçerken doldurucu
içeriğinin ve yoğunluğunun da dikkate alınması gerektiği
görülmüştür.

Abstract

Background: The aim of this study was to compare the
hardness and roughness of the surface of one nanofill
(Filtek Supreme XT) and four nano-hybrid (İvoclar Tetric
EvoCeram, Dentsply Ceram X, Voco Grandio, Bisco
Ælite) composite after polishing.
Methods: Ten specimens of each composite prepared
for each test and were polymerized under a polyester
strip for manufacturer recommendations. After curing
samples were polished with OptiDisc discs for ten
seconds. For surface hardness test, Vicker’s hardest test
used and for the surface roughness test, surface
profilometer was used. For each test three different
locations of each sample were selected and mean values
taken for statistical analysis.
Results: There were significant differences in surface
hardness and surface roughness between composites.
According to results Grandio and Supreme XT showed
highest surface hardness and Supreme XT showed lower
surface roughness values.
Conclusion: In the light of this study, when selecting
composite resin filler content and density should be
considered.
