Abstract

Amaç: Estetik
restoratif CAD/CAM kompoziti (Lava Ulti- mate; 3M ESPE, St.Paul, ABD) ve hibrit
seramik materya- linin (Vita Enamic, Vita Zahnfabrik, Almanya) translüsensi ve
renk stabilitesi hakkında yeterli bilgi bulunmamaktadır. Bu çalışmanın amacı,
restorative CAD/CAM materyallerinin translüsensi ve renk stabilitesini
araştırmaktır.

Gereç ve Yöntem: Onar örnekten oluşan
dört grup, 1 mm kalınlığında hibrit seramik ve rezin nanoseramik kompozit rezin
monolitik bloklardan hazırlandı. Test edilen tüm materyaller için 2M2, yüksek
translüsensili bloklar seçildi. Yüzey bitirmelerinde Lava Ultimate
örnekler
için Sof-Lex (3M ESPE, St.Paul, ABD)
diskler, Vita Enamic için Vita Enamic polishing set (Vita Enamic, Vita
Zahnfabrik, Almanya) kullanıldı. Örneklerin her iki yüzüne de polisaj
uygulandı. Translüsensi parametresi ve renk farklılıkları, örnekler 48 saat
kahve solüsyonunda bekletilmeden önce ve sonrasında CIE L*a*b* sisteminde
spektrofotometre (Vita Easy Shade, Vita Zahnfabrik, Almanya) ile ölçüldü.
Veriler Mann-Whitney U testi ile incelendi (p<.05).

Bulgular: Lava ve Vita Enamic kontrol grupları
arasında anlamlı fark görülmedi (p=1). Kahve solüsyonunda bekletilme sonrasında
CAD/CAM materyallerin translüsensi parametresi değerleri azalırken ∆E renk
farklılıklarında artış gözlendi. Kahvede bekletilme
sonrasında Lava Ultimate (10.9±1), Vita
Enamic’den (9.1±0.7) daha yüksek translüsensi parametresi değeri
sergiledi. Ayrıca kahvede bekletilen Lava
Ultimate örneklerin ∆E değeri (∆E=3.4) Vita Enamic’den (∆E=1.8) daha fazla ve
eşik değerin (∆E=2.7) üstünde ölçüldü.

Sonuç: Çalışmamızda Lava Ultimate daha yüksek
translü- sensi değeri sergiledi ancak daha fazla renk değişimi gösterdi.

EVALUATION OF TRANSLUCENCY AND COLOR STABILITY OF
ESTHETIC CAD/CAM RESTORATIVE MATERIALS

ABSTRACT

Aim: Adequately information is not available about the translucency
and color stability of esthetic restorative CAD/CAM composite (LAVA Ultimate,
3M ESPE, StPaul, USA) and hybrid ceramic material (VITA Enamic, Vita
Zahnfabrik, Germany). The purpose of this study was to investigate the
translucency and color stability of restorative CAD/CAM materials.

Material and Methods: Four groups consist of 10
specimens, were prepared with 1 mm thickness of hybrid ceramic and resin
nano ceramic composite resin monolithic blocks. 2M2 high translucent blocks
were chosen for all tested materials. 
Surface finishing was performed with Sof-Lex (3M ESPE, StPaul, USA)
discs for Lava Ultimate specimens and Vita Enamic polishing set (VITA Enamic,
Vita Zahnfabrik, Germany) was used for Vita Enamic. The polishing procedures
were performed on both sides of the specimens. Translucency parameter and color
differences were measured in the CIE L*a*b* system by spectrophotometer (Vita
Easy Shade, Vita Zahnfabrik, Germany) before and after 48 hours of immersion in
a coffee solution. Data were analyzed with Mann-Whitney U test (p<.05).

Results: There was no significant difference between the Lava control
group and Vita Enamic control group (p=1). After immersion of coffee solution,
translucency parameter values of CAD/CAM materials were decreased and increased
∆E color differences were observed. 
Significant differences were found among coffee groups for all specimens
tested (p<.001). After coffee immersion, Lava Ultimate showed higher
translucency parameter value (10.9±1) than Vita Enamic (9.1±0.7). Also, ∆E
values of Lava Ultimate (∆E=3.4) specimens which stored in coffee solution were
higher than Vita Enamic (∆E=1.8), and were over than threshold ∆E (∆E=2.7).

Conclusion: Lava Ultimate showed more translucency
parameter value, but also showed more staining in our study.
