Biomateryallerin Üniversal Adeziv sistemlere Bağlanma Dayanımının Karşılaştırılması: İn Vitro Çalışma

Amaç: Bu çalışmanın amacı, kalsiyum silikat içerikli biomateryallerin farklı pH sahip Üniversal adeziv sistemlere makaslama bağlanma dayanımını karşılaştırmalı olarak değerlendirilmesidir. Gereç ve Yöntem 20 milimetre (mm) çapında ve 20 mm derinlikte kare kalıplara silindirik boşlukları(4mm çap- 2 mm derinlik) bulunan 63 adet akrilik blok hazırlandı. Dokuz gruba ayrıldı. Üretici firmaların talimatları doğrultusunda her bir biyomateryalden (NeoPutty, Theracal PT, Biodentine) 21 adet olacak şekilde hazırlanan boşluklara yerleştirildi. Biyomateryallerin üzerine Üniversal Adeziv sistemler; Gluma Bond Universal, Single Bond Universal, G-Premio Bond üretici firma talimatına göre uygulandıktan sonra kompozit rezin polietilenden hazırlanmış 2 mm çapında ve 2 mm yüksekliğinde silindirik plastik tüplere yerleştirildi ve 20 sn LED ışık cihazı ile polimerize edildi. Tüm örneklerin makaslama bağlanma dayanımı universal test cihazında Newton cinsinden ölçüldü. Shapiro-wilk testi sonucuna göre istatistiksel Parametrik testlerden Tek Yönlü (one way ANOVA) Varyans Analizi yöntemi uygulandı. Gruplar kendi aralarında Post hoc Tukey HSD testi ile karşılaştırıldı. Bulgular Biodentin ve TheraCal PT grupları arasındaki fark istatistiksel olarak anlamlı bulundu P<0.05. Theracal PT ve NeoPutty grupları arasındaki fark istatistiksel olarak anlamlı bulundu P<0.05. Biodentin ve NeoPutty grupları arasındaki fark istatistiksel olarak anlamlı değil P>0.05. Sonuç Vital pulpa tedavilerinde kalsiyum silikat esaslı rezin içerikli TheraCal PT Üniversal adeziv sistemlerle kullanımı tercih edilebilir. Ancak vital pulpa üzerine etkilerini değerlendiren ileri histolojik çalışmalara ihtiyaç duyulmaktadır. NeoPutty’nin gösterdiği makaslama bağlanma değerleri Biodentin’den düşük olmasına rağmen bu sonuç istatistiksel olarak anlamlı değildi. Kompozit restorasyonlarda adeziv sistemlerin NeoPutty'ye bağlanma mekanizmasını anlamak için invivo çalışmalara ihtiyaç olduğu düşünüldü.

Comparison of Bond Strength of Biomaterials to Universal Adhesive Systems: An In Vitro Study

Aim The aim of this study is to compare the shear bond strength of calcium silicate-containing biomaterials to Universal adhesive systems with different pH. Materials and Methods 63 acrylic blocks with cylindrical cavities (4 mm diameter - 2 mm depth) were prepared in square molds with a diameter of 20 millimeters (mm) and a depth of 20 mm. It was divided into nine groups. In accordance with the instructions of the manufacturers, 21 pieces of each biomaterial (NeoPutty, Theracal PT, Biodentine) were placed in the prepared cavities. Universal Adhesive systems on biomaterials; After Gluma Bond Universal, Single Bond Universal, G-Premio Bond were applied according to the manufacturer's instructions, the composite resin was placed in cylindrical plastic tube with a diameter of 2 mm and a height of 2 mm prepared from polyethylene and polymerized with a LED light device for 20 seconds. Shear bond strength of all samples were measured in Newtons using a universal tester. According to the results of Shapiro-wilk test, One Way (One Way ANOVA) Analysis of Variance method, statistical parametric tests, was applied. The groups were compared among themselves with the Post hoc Tukey HSD test. Results The difference between Biodentin and TheraCal PT groups was statistically significant P<0.05. The difference between Theracal PT and NeoPutty groups was statistically significant P<0.05. The difference between Biodentin and NeoPutty groups was not statistically significant P>0.05. Conclusion In vital pulp treatments, it can be preferred to use with calcium silicate-based resin-containing TheraCal PT Universal adhesive systems. However, further histological studies are needed to evaluate its effects on vital pulp. Although the shear bond values of NeoPutty were lower than Biodentin, this result was not statistically significant. It was thought that in vivo studies are needed to understand the bonding mechanism of adhesive systems to NeoPutty in composite restorations.
