FARKLI DEZENFEKSİYON YÖNTEMLERİNİN CAD / CAM VE KONVANSİYONEL AKRİLİK REZİNLERİN YÜZEY SERTLİĞİNE ETKİSİ

Amaç: Bu çalışmanın amacı, farklı dezenfeksiyon yöntemlerinin (%2 glutaraldehit, %5 sodyum hipoklorit ve mikrodalga) yeni üretilen prefabrike olarak polimerize edilmiş CAD/CAM akrilik rezin, ısı ile ve kimyasal polimerize olan akrilik rezinlerin yüzey sertliği üzerindeki etkisini değerlendirmektir. Gereç ve yöntem: 15 mm çapında 2 mm kalınlığında disk şeklinde hazırlanan örnekler kontrol ve 3 farklı test grubuna ayrılmıştır (n = 8): Grup 1: kontrol, 37°C'de distile su içinde; Grup 2: %2’lik glutaraldehit; Grup 3: %5’lik sodyum hipoklorit; Grup 4: mikrodalga dezenfeksiyonu (650 W / 6 dak). G2 ve G3 örnekleri bir saat boyunca dezenfektan solüsyonda bekletilmiştir. Yüzey sertliği ölçümleri (Vickers Sertliği), 2 yönlü ANOVA ve Tukey’s Honestly Significant Difference testi (α=.05) kullanılarak analiz edilmiştir. Bulgular: Tüm gruplarda en yüksek yüzey sertlik değerleri kontrol gruplarında bulunmuştur. Prefabrike olarak polimerize edilmiş CAD/CAM akrilik rezinler bütün gruplarda en yüksek yüzey sertliği göstermiştir (p<0,001). %5’lik sodyum hipoklorit dezenfeksiyonu, ısı ile ve kimyasal polimerize olan akrilik rezinlerin yüzey sertliği üzerinde etkili olmuştur (p <0,001). Sonuçlar: Bu çalışmanın sınırları dahilinde, yeni üretilen prefabrike olarak polimerize edilmiş CAD/CAM akrilik rezinlerin yüzey sertliği, dezenfektan yöntemlerinden bağımsız olarak dezenfeksiyondan etkilenmemiştir.

Materials and Methods: Disc shaped specimens, 15 mm diameter and 2 mm thickness, were divided into a control and 3 test groups (n=8): Group 1: control, stored in distilled water at 37°C; Group 2: 2% glutaraldehyde; Group 3: 5% sodium hypochlorite; Group 4: microwave disinfection (650 W/6 min). G1 to G3 were immersed for an hour in the disinfectant solution. Measurements of surface hardness (Vickers Hardness) were analyzed using 2-way ANOVA and Tukey’s Honestly Significant Difference (HSD) test (α=.05). Results: The control groups showed the highest surface hardness values in all groups. Pre-polymerized block acrylic resin showed the highest surface hardness in all of the groups (p<0,001). The 5% sodium hypochlorite disinfection had an effect on the surface hardness of heat and self cured acrylic resins (p<0,001). Conclusions: Within the limitation of the current study, surface hardness of newly introduced pre-polymerized acrylic resin was not affected by disinfection regardless of the disinfectant methods.
