ÖZET
 Amaç: Yeni bir cam hibrid restoratif materyalin geniş ve derin 2. sınıf preparasyonlarda 18 ay sonundaki klinik performansını, rezin kompozit ile karşılaştırarak değerlendirmektir. Gereç ve Yöntemler: Otuz yedi hastada proksimal genişliği kasp tepelerinden 1-1,5 mm uzaklıkta olan 108 2. sınıf çürük lezyonu cam hibrid restoratif materyal (EQUIA Forte, GC, Tokyo, Japonya) veya selektif pürüzlendirme ile kombine mikro-hibrid rezin kompozit (G-ænial Posterior, GC, Tokyo, Japonya) kullanılarak iki diş hekimi tarafından üretici talimatlarına göre restore edildi. Restorasyonlar çalışma grubunda yer alan diğer 2 bağımsız gözlemci tarafından uygulandıktan 1 hafta sonra (başlangıç), 6, 12 ve 18. aylarda modifiye USPHS kriterlerine göre değerlendirildi. Tüm kontrol randevularında her 2 gruptan rastgele seçilen bir restorasyon örneğinden negatif replikalar hazırlanarak taramalı elektron mikroskobu (SEM) ile restorasyonların yüzey özellikleri incelendi. Veriler istatistiksel olarak analiz edildi. Bulgular: On sekiz ay sonunda, 32 (kontrollere gelme oranı: %86,5) hastada 90 restorasyon değerlendirildi. 4 cam hibrid restorasyon; 3'ü tamamen düşme ve 1'i proksimal bölgesinde oluşan kırıktan dolayı 12. ayda kaybedildi. Sadece 6 cam hibrid restorasyon başlangıçta, 6, 12 ve 18. aylarda renk açısından bravo olarak skorlandırıldı (p<0,05). İki restoratif materyal arasında diğer değerlendirme kriterleri yönünden anlamlı farklılıklar görülmedi (p>0,05). On sekizinci ay kontrolünde yapılan SEM incelemelerinde her iki restoratif materyal kabul edilebilir yüzey ve kenar uyumu özellikleri gösterdi. Sonuç: Cam hibrid restorasyonlar istatistiksel olarak anlamlı renk uyumsuzluğu göstermesine rağmen, her iki restoratif materyal 18 ay sonra geniş 2. sınıf preparasyonların restorasyonunda başarılı performans gösterdi.

ABSTRACT
 Objective: To evaluate the clinical performance of a glass hybrid restorative compared to a resin composite in the restoration of large and deep class 2 preparations after 18 months. Material and Methods: A total of 108 extended size-with the width of the proximal box not interfering with the peak of the cusps and the proximal box in occlusion-class II lesions in 37 patients were either restored with a glass hybrid restorative (EQUIA Forte, GC, Tokyo, Japan), or with a micro-hybrid composite resin (G-ænial Posterior, GC, Tokyo, Japan) in combination with selective etching by two experienced operators according to the manufacturer's instructions. Two independent examiners evaluated the restorations at baseline and 6-, 12- and 18-month recalls according to the modified USPHS criteria. Negative replicas at each recall were observed under scanning electron microscopy (SEM) to examine surface characteristics. Data were analyzed statistically. Results: After 18 months, 90 restorations were evaluated in 32 (recall rate: 86.5%) patients. Four glass hybrid restorations were missing; 3 were due to bulk and 1 was due to proximal fracture at 12 months. Only 6 restorations were scored as bravo also at baseline, 6-, 12- and 18-month recalls for color (p>0.05). No significant differences were observed between the two restorative materials for the other criteria evaluated (p>0.05). SEM observations exhibited acceptable surface and marginal adaptation characteristics for both restorative materials at 18 months control. Conclusions: Although glass hybrid restorations statistically significant mismatch in color, both restorative materials exhibited successful performances for the restoration of large class 2 preparations after 18-month.
