Farklı Enerji Seviyelerindeki Er:YAG Lazer ile Tamir Edilen Akrilik Kaide Rezininin Bükülme Dayanımı

Amaç: Konvansiyonel akrilik kaide rezininin tamirinde, tamir yüzeylerine uygulanan farklı enerji seviyelerindeki Er:YAG lazerin kaide rezininin bükülme dayanımına etkisini incelemektir. Gereç ve Yöntemler: 160 adet dikdörtgenler prizması şeklindeki akrilik rezin örnek özel bir kalıp kullanılarak üretildi ve tamir yüzeylerine farklı enerji seviyelerinde Er:YAG lazer uygulanmak üzere 4 gruba ayrıldı; Grup 1; kontrol-işlem uygulanmayan grubu, Grup 2; 2 W (200 mJ/atım) lazer uygulanan grubu, Grup 3; 3 W (300 mJ/atım) lazer uygulanan grubu ve Grup 4; 4 W (400 mJ/atım) uygulanan grubu temsil etmektedir. Farklı yüzey işlemlerinden sonra örnekler otopolimerizan akrille tamir edilerek toplam 80 adet (n=20) örnek hazırlandı. Tamir edilen örneklerin bükülme dayanımı ısısal yaşlandırma uygulandıktan sonra universal test cihazı kullanılarak üç noktalı eğme testi ile ölçüldü. Elde edilen verilerin istatistiksel analizi tek yönlü ANOVA ile yapıldı ve gruplara ait ortalamalar Tukey HSD testi kullanılarak karşılaştırıldı (p
