The Bond Strength of Universal Adhesives with Different Acidities to Calcium Silicate-Based Materials

Abstract

Objective: To compare the micro-shear bond strengths of 3 different universal adhesives to 2 different calcium silicate-based materials.Methods: A hole was prepared in the center of the top surfaces of 60 cylindrical acrylic blocks, and the blocks were randomly divided into 2 groups (n=30) according to biomaterial filling; NeoMTA Plus (Avalon Biomed Inc. Bradenton, FL, USA) and ProRoot MTA (Dentsply Tulsa, Tulsa, OK, USA). Biomaterials were prepared according to the manufacturers' instructions. The sample surfaces were flattened after the initial setting, and the samples were incubated for 24h at 37°C. After placing the biomaterials in the prepared holes, the specimens were randomly divided into 3 subgroups (n=10) according to adhesive; G-Premio Bond (GC Corp.

Comparison of Medcem MTA, Medcem Pure Portland Cement and NeoMTA to Pediatric Restorative Materials to Shear Bond Strength

“…40,41 On the contrary, there are studies favoring self-etch systems 42,43 or stating that adhesive mode is irrelevant. 44 Conflicting findings between studies may be due to differences in MTA compositions and the adhesive systems used. Also in this study, restorative materials used in pediatric dentistry were chosen as restorative materials, and SBS was not compared with universal composites.…”

Shear Bond Strength of NuSmile- Neoputty Bio- ceramic Material to Four Different Restorative Materials Used In Pedodontics.

“…Functional monomers have two functional groups; one group that can etch the MTA surface and another that is capable for polymerization. (29,41,44,45) 10-methacryloyloxydecyl dihydrogen phosphate (MDP) monomer is a functional acidic monomer; where its acidity was relied upon to etch the MTA surface, and so can facilitate the resin penetration for producing mechanical interlocking adhesion. In addition, if the adhesive has low viscosity, this can help its easier penetration into the MTA cement.…”

“…As a consequent, it can strengthen the glass ionomer/ MTA bond. (44,45) In the light of those earlier findings, a universal adhesive containing 10-MDP was used in the present study in order to assess its effect on the strength of the adhesive junction between NuSmile-Neoputty to the tested restorative materials and clarify whether it can enhance the bond strength or not.…”

Biomateryallerin Üniversal Adeziv sistemlere Bağlanma Dayanımının Karşılaştırılması: İn Vitro Çalışma

“…Bu tek şişe adezivler, basit uygulama prosedürleri ve kısa uygulama süreleri nedeniyle tercih edilmektedir. 22 ÜA sistemler, yapısında bulunan asidik molekül olan fonksiyonel monomerler sayesinde diş yapısı ile etkileşmektedir. 23,24 Çalışmamızda test edilen önemli ölçüde daha üstün bir bağlanma değeri sergilediğini rapor etmişlerdir.…”

“…Hibrit tabaka içinde 10-MDP-kalsiyum tabakası oluşturduğu iddia edilir. 3,22,23,25 Self-etch 10-MDP içerikli adezivler, Ca iyonlarına, Alüminyum ve zirkonyum oksitlere kimyasal bağlanma gösterir. Bifonksiyonel silan molekülü, silika içeren malzemelere kimyasal olarak bağlanır.…”
