“…It has been reported in other studies that the addition of radiopacifying agents did not affect the ALP activity and also allow the anatomical structures differentiation (22,23). The evaluation of this enzyme allows the determination of the material bioactivity and its potential to promote repair with formation of mineralized tissue (20). The capacity of MTA to induce calcium deposition, as well as its bioactivity has been demonstrated (23).…”

“…A calcium silicate-based cement with ytterbium trifluoride (YbF 3 ) demonstrated interesting physical-chemical properties for use as biomaterial (10). The investigation of materials physicochemical properties is important to predict their clinical application (20). The incorporation of radiopacifiers to CSC may increase the material's setting time (10,18).…”

This study evaluated physicochemical properties, cytotoxicity and bioactivity of MTA Angelus (MTA), calcium silicate-based cement (CSC) and CSC with 30% Ytterbium oxide (CSC/Yb2O3). Setting time was evaluated using Gilmore needles. Compressive strength was evaluated in a mechanical machine. Radiopacity was evaluated using radiographs of materials and an aluminum scale. Solubility was evaluated after immersion in water. Cell viability was evaluated by means of MTT assay and neutral red staining, and the mineralization activity by using alkaline phosphatase activity and Alizarin Red staining. The data were submitted to ANOVA, Tukey and Bonferroni tests (5% significance). The bioactive potential was evaluated by scanning electron microscopy. The materials presented similar setting time. MTA showed the lowest compressive strength. MTA and CSC/Yb2O3 presented similar radiopacity. CSC/Yb2O3 showed low solubility. Saos-2 cell viability tests showed no cytotoxic effect, except to 1:1 dilution in NR assay which had lower cell viability when compared to the control. ALP at 1 and 7 days was similar to the control. MTA and CSC had greater ALP activity at 3 days when compared to control. All the materials present higher mineralized nodules when compared with the control. SEM analysis showed structures suggesting the presence of calcium phosphate on the surface of materials demonstrating bioactivity. Ytterbium oxide proved to be a properly radiopacifying agent for calcium silicate-based cement since it did not affected the physicochemical and biological properties besides preserving the bioactive potential of this material.

“…24 Additionally, multiple recent studies demonstrated that Biodentine had superior bond strength than MTA. 11,[25][26][27] Nagas et al studied the effects of regular concentration of TAP and Ca(OH) 2 on the bond strength of MTA and Biodentine. The study found significantly higher bond strength of Biodentine regardless of the type of medicaments used.…”

Objective Evaluate the effects of typical clinical concentration (1,000 mg/mL), low concentration (1 mg/mL) triple antibiotic pastes (TAP), and double antibiotic pastes (DAP) on the bond strength between various root cements and radicular dentin. Materials and Methods Intact single-rooted human teeth (n = 144) were horizontally decoronated and canals instrumented. The roots were treated for 4 weeks with Ca(OH)2, 1,000 mg/mL of TAP or DAP, and 1 mg/mL of TAP or DAP. Untreated roots served as a control. After treatment, the medicaments were irrigated and each group was divided into three subgroups receiving MTA, Biodentine, or Endosequence putty cement. After 2 weeks, coronal and middle root cylinders were obtained from each root. Push-out bond strength test and failure analysis were performed for all root cylinders. Statistical Analysis Three-way ANOVA, pairwise comparisons and logistic regression were used for statistical analyses. A significance level of 5% was used. Results For MTA applied in the coronal part of the roots, 1 mg/mL DAP and TAP and Ca(OH)2 demonstrated significantly higher bond strength compared with the typical clinical concentration and the control groups. For Biodentine applied coronally in the roots, 1 mg/mL of DAP resulted in significantly higher bond strength than all other groups. For Endosequence putty cement applied coronally in the roots, 1 mg/mL of DAP offered significantly higher bond strength than all groups except for Ca(OH)2. Conclusion The use of 1 mg/mL DAP resulted in significantly higher push-out bond strength compared with the typical clinical concentration of TAP and DAP regardless of the type of the root cement used.

“…6 BD is a relatively new tricalcium silicate-based material which has a short setting time, good handling, and superior mechanical properties compared with other tricalcium silicate-based materials. 7,23 Some authors reported that BD has lower microleakage values and better marginal adaptation than those of MTA. 7,24,25 Parallel to our study, Pradhan et al 26 found no statistically significant difference between two types of MTA and BD.…”

ÖZ GİRİŞ ve AMAÇ: Endodontik tedaviler yüksek başarı oranına sahip olmakla birlikte, tedavilerin başarısız olduğu ve yenilenmesinin mümkün olmadığı vakalarda dişleri ağızda tutabilmek için cerrahi endodontik işlemler gerekebilmektedir. Bu çalışmada; Cam İyonomer Siman (CİS), Mineral Trioksit Agregate (MTA) ve Biodentine (BD)'in retrograd dolgu materyali olarak apikal sızdırmazlık direncinin in vitro koşullarda karşılaştırılması amaçlanmıştır. YÖNTEM ve GEREÇLER: Çalışmada 70 adet tek köklü daimi insan dişi kök ucundan 3 mm kesildi. Kök ucu kaviteleri ultrasonik uç yardımıyla hazırlandıktan sonra CİS, MTA ve BD ile dolduruldu. Tüm örnekler %2'lik metilen mavisinde 48 saat 37°C'de bekletildi. 1 mm kalınlığındaki kök kesitleri stereomikroskop altında dijital olarak fotoğraflandı. Boya penetrasyon alanı, AutoCad programı kullanılarak metilen mavisi ile boyanan yüzeylerin tüm dentin yüzeyine oranlanması ile hesaplandı. Gruplar arasındaki farklılığı saptayabilmek için Kruskal-Wallis H ve çoklu karşılaştırma (post-hoc) testlerinden yararlanıldı (p<0,05). BULGULAR: Deney gruplarında % 0 ila % 95,45 arasında değişen derecelerde mikrosızıntının olduğu belirlendi. MTA ve BD gruplarının, CİS grubuna göre istatistiksel olarak anlamlı derecede daha az sızıntı gösterdiği ancak MTA ve Biodentine grubu arasında sızıntı açısından istatistiksel olarak anlamlı bir fark bulunmadığı saptandı. TARTIŞMA ve SONUÇ: Bu in vitro çalışmada, retrograd dolgu materyali olarak MTA ve BD'nin apikal sızdırmazlık yeteneğinin CİS'e göre belirgin ölçüde üstün olduğu görülmektedir. Anahtar Kelimeler: Apikal rezeksiyon, apikal mikrosızıntı, mineral trioksit agregat, cam iyonomer siman, biodentine ABSTRACT INTRODUCTION: Endodontic treatments have a high success rate but endodontic surgery procedures may be necessary to preserve teeth when the treatments are unsuccessful. The purpose of this study was to compare the sealing ability of glass ionomer cement (GIC), mineral trioxide aggregate (MTA),and BiodentineTM (BD) in vitro. METHODS: 70 human single-rooted permanent teeth were resected at 3 mm from the apex. Root-end cavities were prepared using an ultrasonic tip and filled with GIC, MTA, or BD. All specimens were soaked in %2 methylene blue at 37°C for 48 hours. The 1-mm thick roots sections were digitally photographed under a stereomicroscope. With the use of an AutoCad program dye penetration area was calculated as the methylene blue-infiltrated surface divided by total dentin area. The Kruskal-Wallis H test and post-hoc multiple comparison test were used to determine which groups differed from each other (p < 0.05). RESULTS: The experimental groups presented different microleakage values varying between 0% and 95.45%. MTA and BD showed a statistically significant difference in microleakage compared with GIC, but no significant difference was obtained between MTA and BD. DISCUSSION AND CONCLUSION: When used as a retrograde filling material, MTA and BD were significantly superior in terms of apical microleakage compared with GIC.
