Abstract

Amaç: Bu çalışmanın amacı farklı kalınlıklarda ve farklı
yapıdaki tam seramik materyallerinin translusenstlik değerlerini incelemektir.
Gereç ve Yöntem: Beş farklı seramikten (feldspatik, lösit ile
güçlendirilmiş, lityumdisilikat ile güçlendirilmiş,
altyapı zirkonya,
monolitik zirkonya) ve iki farklı kalınlıkta (0,5-1 mm) örnekler
hazırlanmıştır. Her bir grup için örnek sayısı beş olarak saptanmıştır.
Örneklerin kontrastlık oranlarını elde etmek için elde etmek için
spektrofotometreyle beyaz zemin (L*w) ve siyah
zemin (L*b) üzerinde üçer adet ölçüm gerçekleştirilmiştir. Veriler iki yönlü
varyans analizi ile değerlendirilmiştir. Gruplar arası
karşılaştırmalar için Tukey’s HSD testi kullanılmıştır.

Bulgular: 0,5 mm kalınlıktaki gruplar kendi aralarında
karşılaştırıldığında feldspatik ve lösit ile güçlendirilmiş cam seramik dışında
bütün gruplar arasında istatistiksel olarak anlamlı
farklılıklar görülmüştür. 1 mm kalınlığındaki gruplar kendi aralarında
karşılaştırıldığında altyapı zirkonya ve monolitik zirkonya dışında bütün
gruplar arasında istatistiksel olarak anlamlı farklılık bulunmuştur.

Sonuç: Kalınlık ve yapısal farklılıklar seramiğin translusensi
özelliğini etkilemektedir.

Anahtar Kelimeler: Tam seramik,  translusensi, kontrastlık

COMPARISON OF TRANSLUCENCY VALUES OF
ALL CERAMIC MATERIALS WITH DIFFERENT STRUCTURES AND THICKNESSES

ABSTRACT

Aim: The aim of the study
is to evaluate the translucency of all ceramic materials with different
thicknesses and structures.

Material and Methods: Specimens
with two different thicknesses (0.5-1 mm) were prepared from five different
ceramic materials (feldspathic, leucite-reinforced, lithium disilicate
reinforced, framework zirconia, monolithic zirconia). Each group contained five
specimens. Three measurements were made with spectrophotometry to obtain the
contrast ratios of the materials over a white background (L*w) and a black
background (L*b). The data was analysed by two-way analysis of variance. The
groups were compared by Tukey’s HSD test.

Results: Groups which have a
thickness of 0.5 mm had statistically significant differences except feldspatic
and leucite reinforced ceramic. Groups which have a thickness of 1 mm had
statistically significant differences except framework zirconia and monolithic
zirconia.

Conclusion: Thickness
and structural differences affects the translucency feature of ceramic.

Keywords: All ceramic, translucency,
