Abstract

Aim: The purpose of this study was to evaluate effect of four different surface treatment procedures on color alterations of zirconia restorations that was repaired with composite resin using two different intraoral porcelain repair systems. Materials and method: 80 zirconia and 80 zirconia-based porcelain veneer were used to prepare disc-shaped specimens (2 x 5 mm). L*a*b* values of specimens were recorded, and the zirconia and the porcelain specimens were divided into two main group for two different intraoral porcelain repair systems (Clearfil Repair ve Ceramic Repair N). 40 specimens in that main groups were divided into four subgroup (N = 10) in order to perform four different surface treatment procedures (surface grinding with diamond bur, intraoral sandblasting, long pulse and short pulse of Er,Cr:YSGG laser irradiation). The intraoral porcelain repair kits and composite resins (Clearfil Majesty Esthetic Tetric N Ceram) that are compatible with the repair kits were applied to surface of the specimens. Composite resins were built-up on each zirconia and porcelain surfaces using a standard teflon mold (2 x 2 mm) and incrementally filled. L*a*b* values of repaired specimens were recorded and ΔE values were calculated using the formula. Color differences between the initial and final records were statistically analyzed (1-way ANOVA). Results: The color changes which calculated upon surface treatments and intraoral porcelain repair kits were higher than clinical acceptability threshold (∆E = 5.5). Zirconiabased porcelain specimens that were treated long pulse laser irradiation and repaired using Clearfil Repair intraoral porcelain repair kit group showed lowest ∆E value (∆E = 5.90). Short pulse laser irradiation applied zirconia specimens that were repaired with Clearfil Repair kit group illustrated highest color changes (∆E = 13.65) among the tested groups. Conclusion: The color differences of repaired zirconia and zirconia-based porcelain veneer, regardless of their type, surface treatment method, and applied intraoral porcelain repair kit, was not clinically acceptable when compared to the initial shade of the specimens.

Özet

Amaç: Çalışmamızın amacı iki farklı ağız içi porselen tamirseti (APTS) kullanılarak kompozit rezinle tamir edilen zirkonyarestorasyonlarda dört farklı yüzey hazırlık yönteminin rengeolan etkilerinin değerlendirilmesidir.Gereç ve yöntem: Disk şeklinde (2 x 5 mm) 80 adetzirkonya ve 80 adet zirkonya destekli porselen örnekhazırlanmıştır. Örneklerin L*a*b* değerleri kaydedilmiş ve ikifarklı APTS (Clearfil Repair ve Ceramic Repair N) için porselenve zirkonya örnekler ikiye ayrılmıştır. Bu ana gruplarda 40örnek dört farklı yüzey hazırlık işleminin (elmas frezlepürüzlendirme, ağız içi kumlama, uzun ve kısa atımEr,Cr:YSGG lazer ışınlama) uygulanması için 4 alt gruba (N =10) daha ayrılmıştır. APTS’leri ve bu kitlerle uyumlu kompozitrezinler (Clearfil Majesty Esthetic ve Tetric N Ceram) örnekyüzeylerine tatbik edilmiştir. Kompozit rezinler her birzirkonya ve porselen yüzeyine standart bir teflon kalıp (2 x 2mm) kullanılarak inkremental teknikle yerleştirilmiştir. Tamiredilen örnek yüzeylerinde L*a*b* değerleri kaydedilmiş olup,ilgili formül kullanılarak ΔE değerleri hesaplanmıştır. Başlangıçve sonuç renk farklılıkları kaydedilip istatistiksel analiz (tekyönlü varyans analizi) yapılmıştır.Bulgular: APTS ve yüzey hazırlık işlemlerine görehesaplanan renk farklılıkları klinik olarak kabul edilebilirdeğerden (∆E = 5.5) yüksektir. Zirkonya destekli porselenörneklerde uzun atım lazer ışınlaması ve Clearfil Repair APTSuygulanan grup en düşük ∆E değerini (∆E = 5.90)göstermiştir. Kısa atım lazer ışınlaması ve Clearfil Repair APTSuygulandığı zirkonya örneklerin grubu diğer gruplara göre enyüksek renk değişikliğini (∆E=13.65) sergilemiştir.Sonuç: Tamir edilen zirkonya ve zirkonya destekliporselenlerin ilk renklerine göre renk farklılıkları; tiplerine,kullanılan yüzey hazırlık yöntemlerine ve uygulananAPTS’lerine bağlı olmaksızın klinik olarak kabul edilebilirdeğildir.
