Purpose: The aim of this study was to evaluate the effect of thickness of zirconia on curing efficiency of resin cements.

Materials and Methods: 4 discs with 4.0 mm in diameter were prepared from non-HIP translucent zirconia blocks using a CAD/CAM system and feldspathic ceramic was layered onto discs. Thus, 4 ceramic disc samples were fabricated: (G) 0.5 mm zirconia- as a control group, (G1) 0.5 mm zirconia and 0.5 mm feldspathic, (G2) 1.0 mm zirconia and 0.5 mm feldspathic and (G3) 2.0 mm zirconia and 0.5 mm feldspathic ceramic layer. 2 different dual cure cements were polymerized using a LED curing unit. Degree of conversion was evaluated using Vickers Hardness Test and depths of cure of samples were measured. Data were analyzed statistically using One-way ANOVA and Tukey’s HSD test (p<0.05).

Results: Microhardness and depth of cure values were different under same thickness of ceramic discs for two resin cements. As the thickness of the zirconia discs increased, the microhardness values and depth of cure decreased.

Conclusion: Photocuring time cannot be the same for all clinical conditions, under thicker zirconia restorations (>2.0 mm), an extended period of light curing or a light unit with a high irradiance should be used.

Amaç: Bu çalışmanın amacı zirkonya kalınlığının reçine simanın polimerizasyonu üzerine etkisinin değerlendirilmesidir. Gereç ve Yöntem: 4.0 mm çapında 4 adet disk non-HIP zirkonya bloklardan CAD/CAM sistemi kullanılarak hazırlandı ve feldspatik seramik diskler üzerine tabakalama tekniği ile uygulandı. Bu şekilde 4 adet seramik disk deney örneği elde edildi: (G) 0.5 mm zirkonya kontrol grubu, (G1) 0,5 mm zirkonya ve 0,5 mm feldspatik, (G2) 1.0 mm zirkonya ve 0.5 mm feldspatik ve (G3) 2.0 mm zirkonya ve 0.5 mm feldspatik seramik katmanı. LED ışık cihazı kullanılarak 2 farklı dual cure reçine siman polimerize edildi. Dönüşüm derecesi Vickers sertlik değeri kullanılarak değerlendirildi ve örneklerin polimerizasyon derinliği ölçüldü. Verilerin istatistiksel değerlendirilmesi tek yönlü varyans analizi (ANOVA) ve Tukey’s HSD testleri ile yapıldı (p < 0.05). Bulgular: Mikrosertlik ve polimerizasyon derinliği, aynı kalınlıktaki seramik örnekler altında iki farklı reçine siman için anlamlı farklılık göstermiştir. Zirkonya kalınlığı arttıkça, mikrosertlik değerleri ve polimerizasyon derinliği azalmıştır. Sonuç: Işıkla polimerizasyon süresi farklı klinik durumlar için aynı olamaz. Kalın zirkonya restorasyonlar altında ( > 2.0 mm) ışıkla polimerizasyonun süresini uzatmak veya yüksek enerjiye sahip bir ışık ünitesi kullanmak uygun olabilir.
