Abstract

Background:The aim of this study is
to compare new dental composite materials produced for posterior or universal
use in terms of their mechanical properties such as flexural strength, micro
hardness and surface roughness.

Methods:New
formulation composites NOVA Compo-HS,
NOVA Compo-N and currently existing composites: Photoposterior, Estelite
Posterior, X-tra fill, AELITE™All-Purpose
Body, Filtek Bulkfill, Tetric N-Ceram Bulkfill were used in
this study.20 cylindrical specimens were prepared (10x2mm) of each material.
Vickers hardness was determined under 300g load on the surface of each
specimen. Surface roughness was measured with Computerize Roughness Tester twice as Ra on each specimen and mean
roughness value was obtained. After that, 20 rectangular specimens (2x2x25mm)
were prepared of each material and the specimens were tested for flexural
strength using a three-point bending test with an Instron machine at a
crosshead speed of 1mm/min. For statistical analyses, One–way ANOVA, Tukey’s HSD and Scheffe
were used.

Results:It was observed that Photoposterior and AELITE™All-Purpose exhibited significantly higher bending strength
when compared to Compo-HS and Compo-N (p <0.05). Photoposterior; displayed higher microhardness values than all
other composites (P < 0.05). The surface roughness values of Compo HS and
Compo-N were observed to be lower than X-tra fill and AELITE ™ All-Purpose (p
<0.05). There is no statistically significant difference between Compo-HS,
Compo-N Filtek Bulkfill and Tetric N-Ceram (p>0.05).

Conclusions:The results of this
study suggest that Compo-N can offer
similar performance to other universal composites. However, Compo-HS composite material is
insufficient for restoration especially in posterior teeth.

YENİ İKİ TİP KOMPOZİT MATERYALİN MEKANİK ÖZELLİKLERİNİN KARŞILAŞTIRILMASI

Abstract

Amaç: Bu çalışmanın amacı posterior ve üniversal kullanım
için üretilen dental kompozit materyalleri, bükme dayanımı, mikro sertlik ve
yüzey pürüzlülüğü gibi mekanik özellikleri açısından şu
an piyasada yaygın olarak kullanılan kompozit materyallerle karşılaştırmaktır. 

Gereç ve Yöntemler: Bu çalışmada, yeni üretilen NOVA Compo-HS ve NOVA Compo-N
ile şu an piyasada yaygın olarak kullanılan kompozit
materyaller Photoposterior,
Estelite Posterior, X-tra fill, AELITE™ All-Purpose Body, Filtek
Bulkfill, Tetric N-Ceram Bulkfill
kullanıldı. Her bir materyalden silindir şeklinde (10x2mm boyutlarında) 20’şer
örnek hazırlandı ve sonrasında örneklerin Ra cinsinden yüzey pürüzlülüğü ve Vickers sertlik değerleri belirlendi.
Daha sonra her bir materyalden (2x2x25 mm boyutunda) dikdörtgen şeklinde
örnekler hazırlanarak, instron cihazında 1 mm/dk hızda bükme dayanımı değerleri
belirlendi. İstatistiksel analiz için tek yönlü ANOVA ve Tukey’s HSD ve Scheffe
testleri kullanıldı.

Bulgular: Materyaller arasında sertlik, pürüzlülük ve bükme
dayanımları açısından farklılıklar gözlendi (P<0.05). Photoposterior ve AELITE™
All-Purpose, Compo-HS ve Compo-N ile karşılaştırıldığında
belirgin olarak daha yüksek bükme dayanımı sergilediği gözlendi (p<0.05). Photoposterior; çalışmada kullanılan
kompozitlerden daha yüksek mikro sertlik değeri gösterdi (P < 0.05). Compo-HS  ve Compo-N’in
yüzey pürüzlülük değerleri X-tra
fill ve AELITE™ All-Purpose’dan daha düşük olduğu
gözlendi (p<0.05). Compo-HS ve Compo-N ile Filtek Bulkfill ve Tetric
N-Ceram Bulkfill arasında yüzey sertlikleri açısından istatistiksel
açıdan anlamlı bir fark gözlenmedi.

Sonuçlar: Bu çalışmada kullanılan mekanik test sonuçlarına göre yeni formülasyon kompozit Compo-N
piyasada bulunan diğer üniversal kompozitlere benzer bulunarak, onlar kadar yeterli bulunmuştur. Ancak posterior dişler için
üretilen Compo-HS,
her ne kadar yüzey pürüzlülüğü açısından başarılı olsa da mekanik özellikleri
bakımından diğer posterior kompozitler kadar yeterli bulunmamıştır.

Anahtar Kelimeler: kompozit rezin, bükülme dayanımı, mikro sertlik, yüzey
