AMAÇ: Bu çalışmanın amacı yeni bir materyal grubu olan alkasitin kahve solüsyonuna maruz kalmasından sonra tekrar cilalama yapılmasının oluşan renk değişimine etkisini değerlendirmektir.
YÖNTEM: 8 mm çapında ve 2 mm yüksekliğinde teflon kalıplar içerisine yerleştirilen alkasit materyali mylar strip uygulaması altında polimerize edildi ve toplam 32 adet örnek elde edildi. Örnekler rastgele gruba ayrıldı. Grup1: Elmas grenli polisaj lastikleri (L), Grup2: Aliminyum oksit diskleri(D) uygulanarak polisaj işlemi tamamlandı. İlk renk ölçümü yapıldıktan sonra kahveye daldırıldı ve 1 hafta sonra ölçüm tekrarlandı. L kendi içinde iki grubu ayrılarak(n=8) lastik (LL) ve diskler (LD) ile yeniden polisaj işlemi uygulandı. D grubunada lastik (DL) ve disk (DD) ile yeniden polisaj yapıldı ve renk ölçümleri tekrarlandı. Bulgular tek yönlü ANOVA ve Tukey testi kullanılarak %95 güven aralığında analiz edildi.
BULGULAR: En fazla renk değişimi (ΔE00) L’de olmuştur. 1 haftanın sonunda L ve D grupları arasında benzer renk değişiklik değerleri bulunmuştur (p> .05). LL ve LD grupları arasında fark yoktur. DD grubunda LL ve LD gruplarına göre önemli derecede daha az renk değişimi gözlendi (p = .003, p = .042, sırasıyla) Benzer şekilde, DL grubu LL grubuna göre daha az renk değişimi göstermiştir (p = .015).
SONUÇ: Alkasitin renk stabilitesi polisaj prosedüründen etkilenmiştir. Tekrar cilalama işlemi renk değişimini azaltsa da klinik olarak kabul edilebilir seviyelere getirememiştir.
Objectives: An esthetic restoration with an unacceptable color is the main cause for replacement of anterior tooth restorations. The aim of this study is to evaluate the effect of repolishing on the color change of the new material group of alkasite after exposure to coffee solution.
Materials and Methods: Alkasite material placed in Teflon molds with a diameter of 8 mm and a height of 2 mm was polymerized under the application of mylar strip and a total of 32 samples were obtained. The samples were randomly immersion into groups. Group R: Diamond grained polishing rubbers, Group D: Aluminum oxide discs are applied and the polishing process is completed. After the first color measurement was made, it was immersed in coffee and the measurement was repeated 1 week later. L was divided into two groups (n=8) and repolished with rubber (RR) and discs (RD). In the D group, re-polishing was done with rubber (DR) and disc (DD) and color measurements were repeated. Results were analyzed by using one-way ANOVA and Tukey test at 95% confidence interval.
Results: The greatest color change (ΔE00) was in group R. At the end of seven days, similar color change values were found between the groups of R and D (p > 0.05). There is no difference between the RR and RD groups. Significantly less color change was observed in the DD group than in the RR and RD groups (p = .003, p = .042, respectively). Similarly, the DR group showed less color change than the RR group (p = .015).
Conclusions: The color stability of the alkasite was affected by the polishing procedure. The repolishing process reduced the color change, but not at a clinically acceptable level.
