Kalsiyum Silikat Simanların Cam İyonomer Esaslı Materyallerle Makaslama Bağlanma Dayanımının Karşılaştırılmalı Değerlendirilmesi

Abstract

Amaç: Bu çalışmada kalsiyum silikat esaslı MTA ve Biodentin materyallerinin üzerine uygulanan rezin modifiye cam iyonomer siman (RMCİS) ve geleneksel cam iyonomerrestoratif materyalin (GCİR) makaslama bağlanma dayanımdeğerlerinin karşılaştırmalı olarak araştırılması amaçlandı. Yöntem: MTA (n=24) ve Biodentin (n=24) materyal örnekleri, 5 mm çapındaki ve 2 mm derinliğindeki metal kalıplar kullanılarak hazırlandı ve akrilik bloklara gömüldü.Her iki materyal için hazırlanan örnekler RMCİS (Fuji II) ve GCİR (Voco Inonofil) alt gruplarına eşit (n=12) ve randomize olacak şekilde ayrıldı. Restoratif materyaller iç çapı 2 mm ve yüksekliği 2 mm olan silindir şekilli plastik tüpler aracılığıylaMTA ve Biodentin örneklerinin merkezine yerleştirildi.Makaslama bağlanma dayanım değerleri universal test cihazı ile ölçüldü ve veriler MPa cinsinden kaydedildi. Veriler Mann-Whitney U testi ile analiz edildi. İstatistiksel anlamlılık değeri 0,05 olarak alındı. Bulgular: MTA üzerine uygulanan RMCİS’in makaslama bağlanma dayanım değerleri, GCİR’e göre istatistiksel anlamlıfarklılıkla daha yüksekti (p<0,003). Biodentin üzerine uygulanan RMCİS’in ortalama bağlanma dayanım değerleri ise, GCİR’e göre daha yüksek olmakla birlikte, bu fark istatistiksel olarak anlamlı değildi (p=0,057). Hem RMCİShem de CGİR kullanımında, MTA ve Biodentin arasında makaslama bağlanma dayanım değerleri bakımından anlamlı bir farklılık tespit edilmedi (sırasıyla p=0,133 ve p=0,273). Sonuçlar: Çalışmaya dahil edilen tüm bağlanma kombinasyonları özelinde, MTA üzerine uygulanan RMCİS örnekleri en yüksek makaslama bağlanma dayanımınısergiledi. Biodentin üzerine uygulanan CGİR ise en zayıf kombinasyon olarak tespit edildi. Elde edilen sonuçlar bazında, MTA ve Biodentin üzerine RMCİS uygulanmasının daha güçlü mekanik bağlanmayı sağlamış olup, klinik öneriler sunulabilmesi ve bu sonuçların doğrulanması için ileri çalışmaların uygulanması önerilmektedir.

Comparative evaluation of the shear bond strength between different calcium silicate cements and glass ionomer-based materials

Abstract

OBJECTIVE: This study aimed to compare shear bond strength (SBS) values of resin-modified glass ionomer cement (RMGIC) and conventional glass ionomer restorative (CGIR) applied on calcium silicate-based MTA and Biodentin materials. METHOD: MTA (n=24) and Biodentin (n=24) material samples were prepared using metal moulds with a diameter of 5 mm and a depth of 2 mm and embedded in acrylic blocks. The samples of MTA and Biodentin were randomly assigned to RMGIC (Fuji II) and CGIR (Voco Inonofil) subgroups in equal (n=12). Restorative materials were placed at the centre of MTA and Biodentin using cylindrical plastic tubes (2 mm × 2 mm). SBS values were measured using a universal testing machine and recorded in MPa. The data were analysed using the Mann-Whitney U test. Statistical significance level was set at 0.05. RESULTS: SBS values of RMGIC applied to MTA were significantly higher than CGIR (p<0.003). Mean SBS values of RMGIC applied to Biodentin were higher than those of CGIR; however, this difference was not statistically significant (p=0.057). Also, no significant difference was detected in SBS values between MTA and Biodentin when using both RMGIC and CGIR (p=0.133 and p=0.273, respectively). CONCLUSION: For all combinations in the current study, RMGIC samples applied to MTA showed the highest SBS. CGIR applied to Biodentin was found as the weakest combination. Based on the results obtained, the application of RMGIC on MTA and Biodentin has provided more acceptable mechanical bonding. Further studies are recommended to confirm these results and to provide clinical recommendations.
