Characterisation of the calcium silicate‐based cement–composite interface and the bonding strength with total‐etch or single/two‐stage self‐etch adhesive systems

Abstract

Due to favourable biological and physical properties, calcium silicate‐based cements (CSCs) are biocompatible materials used widely for vital pulp therapies. Sealing efficacy between the adhesive system and CSC determines the clinical success of treatment. This study aimed to evaluate the shear bond strength (SBS) of CSC to composite resin with different adhesive systems and to analyse the CSC–composite interface. Mineral trioxide aggregate (MTA) (ProRoot MTA; Dentsply Tulsa Dental, Tulsa, OK), Biodentine (Septodont, Saint‐Maur‐des‐Fossés, France) and NeoMTA Plus (Avalon Biomed Inc., Bradenton, FL) samples (n = 90) were placed in the cavities and divided into three subgroups according to the adhesive family (n = 10). SBSs were measured using a universal testing machine. The interfaces were examined using a scanning electron microscope (SEM) (×1000). NeoMTA Plus showed significantly higher SBS values than MTA and Biodentine (P < 0.0001). The application of total‐etch adhesive system over Biodentine and NeoMTA Plus provided the statistically highest bond strength (P < 0.05). However, when the SBS values of MTA subgroups were compared, different adhesive families applied over MTA did not make a significant difference in SBS values (P > 0.05). Based on SEM analyses, the specimens exhibit no gaps, cracks or delamination within the adhesive layer, which indicates a good adhesion between the CSC–composite interface in all subgroups. In conclusion, the different adhesive families used over CSC did not influence interfacial gap formation.

Morphological Interface Between Restorative and Pulp-Capping Materials: A Systematic Review

“…Therefore, as Figure 1 search flowchart demonstrates, 5 studies were included for qualitative data synthesis. [20][21][22][23][24] In Table 1, the literature search findings are outlined.…”

“…The quality assessment results using the "Modified CONSORT checklist of items for reporting in vitro studies of dental materials" (Faggion, 2012) 15 are presented in Table 2. From a total of 5 studies assessed, 4 studies had results between 50% and 60% in terms of the quality of the data reported in their respective papers, [20][21][22][23] while the study by Xavier et al 24 had the highest quality assessment report at 70%. All the articles presented a well-summarized abstract, specific background, and explanation of rationale, as well as clear objectives and/or hypotheses (items 1, 2a and 2b).…”

“…they were used to carry out fracture type analysis on a stereomicroscope 21 and shear bond strength tests, 24 investigations out of the scope of this review. Statistical analyses and outcomes along with their significance levels (items 10 and 11) were performed and reported in all studies except for the manuscript by Camilleri 20 which investigated only three samples and therefore not suitable to carry out.…”

Biomateryallerin Üniversal Adeziv sistemlere Bağlanma Dayanımının Karşılaştırılması: İn Vitro Çalışma

“…17 KS simanlar ve adeziv sistemler arasında bağlanma gücü, vital pulpa tedavisinin başarısını doğrudan etkiler. 10 Restoratif tedavinin uzun süreli başarısı için biyomateryaller ile restoratif materyal arasındaki bağın kalitesi hayati önem taşımaktadır. KS simanlar ile kompozit rezin arasındaki düzgün stres dağılımı biyomateryal ve kompozit rezinin fizikokimyasal özelliklerine ayrıca ara yüzeyi oluşturan adeziv sistem tipine de bağlıdır.…”

“…Biodentin'e, hızlandırıcı olarak kalsiyum klorür eklenmiş ve sertleşme süresi 12 dakika olarak bildirilmiştir. 10 Kalsiyum silikat esaslı hidrofilik simanların toz-likit ile karıştırılması sırasında heterojen kıvam dezavantajının üstesinden gelmek için önceden karıştırılmış trikalsiyum silikat esaslı simanlar piyasaya sürülmüştür. 11 Son zamanlarda, hem Biodentin hem de MTA'nın klinik uygulamalarını paylaşan kullanıma hazır pat halinde yeni biomateryal NeoPutty (NuSmile, Houston, TX, USA) geliştirilmiştir.…”
