Evaluation of shear bond strength of two resin-based composites and glass ionomer cement to pure tricalcium silicate-based cement (Biodentine®)

Abstract

ObjectivesTricalcium silicate is the major constituent phase in mineral trioxide aggregate (MTA). It is thus postulated that pure tricalcium silicate can replace the Portland cement component of MTA. The aim of this study was to evaluate bond strength of methacrylate-based (MB) composites, silorane-based (SB) composites, and glass ionomer cement (GIC) to Biodentine® and mineral trioxide aggregate (MTA). Material and MethodsAcrylic blocks (n=90, 2 mm high, 5 mm diameter central hole) were prepared. In 45 of the samples, the holes were fully filled with Biodentine® and in the other 45 samples, the holes were fully filled with MTA. The Biodentine® and the MTA samples were randomly divided into 3 subgroups of 15 specimens each: Group-1: MB composite; Group-2: SB composite; and Group-3: GIC. For the shear bond strength (SBS) test, each block was secured in a universal testing machine. ResultsThe highest (17.7±6.2 MPa) and the lowest (5.8±3.2 MPa) bond strength values were recorded for the MB composite-Biodentine® and the GIC-MTA, respectively. Although the MB composite showed significantly higher bond strength to Biodentine (17.7±6.2) than it did to MTA (8.9±5.7) (p<0.001), the SB composite (SB and MTA=7.4±3.3; SB and Biodentine®=8.0±3,6) and GIC (GIC and MTA=5.8±3.2; GIC and Biodentine=6.7±2.6) showed similar bond strength performance with MTA compared with Biodentine (p=0.73 and p=0.38, respectively). ConclusionsThe new pure tricalcium-based pulp capping, repair, and endodontic material showed higher shear bond scores compared to MTA when used with the MB composite.

A chemical activity evaluation of two dental calcium silicate-based materials

“…The performed research showed minimal micro-leakage values for Biodentine. Its modified composition and a novel way of preparing (prepared within a closed capsule using a mixing device) improved its properties, making the use of Biodentine more convenient and efficient [2]. Such results were also confirmed in the studies of Kokate et al, wherein the marginal seal between Portland cement based materials like Biodentine and MTA was evaluated [7].…”

Bio-Inductive Materials in Direct and Indirect Pulp Capping—A Review Article

“…Although Biodentine offers many advantages over MTA, it presented significantly lower SBS values than MTA to restorative materials, including composite (Filtek Z250, 3M, Saint Paul, MN, USA), compomer (Dyract XP®) and RMGI cement (Photac-Fil Quick Aplicap, 3M, Saint Paul, MN, USA) [116]. On the other hand, another study showed clinically acceptable scores and higher SBS of Biodentine compared to MTA when used with the methacrylate-based composite [53]. Inferior results obtained with Biodentine might be explained by the deficient intrinsic maturation, which can take over 2 weeks [87,88].…”

Evaluation of Shear Bond Strength of the Composite to Biodentine with Different Adhesive Systems

“…Jak wynika z przeglądu piśmiennictwa, jest to rów-nież metoda najczęściej opisywana w metodologii badań nad materiałami na bazie krzemianu trój-wapniowego [6][7][8]. Badania własne dotyczyły oceny jakości połą-czenia Biodentine z materiałem kompozytowym w zależności od czasu aplikacji i zastosowania różnych systemów adhezyjnych o różnych protokołach stosowania klinicznego.…”

“…Cantekin i Avci [8] zaprojektowali badanie porównujące wytrzymałość na ścinanie połączenia kompozytów na bazie metakrylanów i siloranów oraz konwencjonalnych cementów szkło-jonomerowych (GIC) zarówno z materiałem Biodentine, jak i MTA. Oceny dokonali po całkowitym zwią-zaniu materiałów, odpowiednio po 15 min dla Biodentine i po 96 godzinach dla MTA.…”
