“…The failure modes of AMTA and GCMTA were predominately adhesive, but predominately cohesive for BD. These findings are in agreement with previous studies that reported adhesive bond failure with MTA and cohesive bond failure with BD 24,25) . The differences in bond strengths and failure modes among the tested cements may also be explained by the differences in the particle sizes, which may have an effect on the penetration of cement into dentinal tubules 25) .…”

This study evaluated the push-out bond strength of 0%, 0.5%, 1.0%, 2.0% and 3.0% (w/w) casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-modified calcium silicate-based cements (CSCs). The push-out bond strength of a trial MTA was also compared with two CSCs (Biodentine ™ and Angelus ® MTA). Three hundred 1 mm thick horizontal root sections were prepared from 60 singlerooted human teeth. The canal space of each section was enlarged and filled with the cements. The sections were stored in a phosphate buffer solution. After incubation for 2 months, the push-out bond strength was measured and the data were analyzed using one way analysis of variance followed by Tukey's test. The addition of CPP-ACP to the test cements increased the push-out bond strength (p<0.05). The push-out bond strength of Biodentine ™ was higher than the other cements (p<0.05). There was no statistically significant difference between Angelus ® MTA and the trial MTA with most of CPP-ACP concentrations.

“…Mineral trioxide aggregate (MTA), a calcium silicate-based cement, has rapidly gained popularity due to its ability to resist leakage and its superior marginal adaptation to the dentinal walls [1] . It is composed of tricalcium silicate, dicalcium silicate, bismuth oxide, tricalcium aluminate, and gypsum [6] . It has been used in numerous clinical situations such as direct pulp capping, repair of root perforations, apexogenesis, apexification, and as a root-end filling material [7] .…”

“…Recently, 2 new calcium silicate-based cements were introduced into the market [6,10] . The first was Biodentine TM (Septodont, Saint Maur des Fossés, France), which is composed mainly of purified tricalcium silicate powder, small amounts of dicalcium silicate, calcium carbonate, and an opaque calcium chloride liquid [10] .…”

of 1 mm/min. Samples were analyzed under a light microscope to determine the nature of bond failure. Ten samples (2 mm thick) were prepared for all the materials, and Vickers microhardness was determined using a digital hardness tester. Data were analyzed using one-way analysis of variance and Tukey-Kramer multiple comparison tests at a significance level of p < 0.05. Results: Biodentine (42.02; 39.35 MPa) and ProRoot MTA (21.86; 34.13 MPa) showed significantly higher bond strengths than BioAggregate (6.63; 10.09 MPa) in coronal and apical root dentin, respectively ( p < 0.05). Biodentine also differed significantly from ProRoot MTA in coronal dentin. Bond failure was predominantly adhesive in Biodentine and ProRoot MTA, while BioAggregate showed predominantly mixed failure. ProRoot MTA (158.52 HV) showed significantly higher microhardness and BioAggregate (68.79 HV) showed the lowest hardness. Conclusion: Biodentine and ProRoot MTA showed higher bond strength and microhardness compared to BioAggregate. AbstractObjective: This was an in vitro evaluation of push-out bond strength and surface microhardness of calcium silicatebased biomaterials in coronal and apical root dentin. Materials and Methods: Ninety sections (2 mm thick) of coronal and apical root dentin were obtained from roots of 60 extracted teeth; the canals were enlarged to a standardized cavity diameter of 1.3 mm. Sections were randomly divided into 6 groups ( n = 15 per group), and cavities were filled with Biodentine TM , BioAggregate, or ProRoot mineral trioxide aggregate (MTA), according to the manufacturers' instructions. Push-out bond strength values were measured using a universal testing machine under a compressive load at a speed Significance of the StudyIn this study, the push-out bond strength and microhardness of 3 materials, ProRoot MTA, Biodentine, and BioAggregate, were compared. Biodentine and ProRoot MTA had higher bond strength and microhardness values than BioAggregate, and hence could be the materials of choice for root repair procedures and retrograde fillings.

ÖZAmaç: BioAggregate simanı ve X-tra base kompozit rezinin push-out bağlantı dayanımlarını ve push-out bağlantı dayanımlarına EDTA ve klorheksidin irrigasyon solüsyonlarının etkisinin karşılaştırılmasıdır. Gereç ve Yöntem:Çalışmaya 24 adet maksiller orta keser diş dahil edildi. Dişlerin apikali #40 olacak şekilde ProTaper Next döner alet sistemi ile şekillendirildi. Daha sonra çapı 1.25 mm olan paralel bir post dirili yardımıyla kök kanalı içerisinde 10 mm uzunluğunda boşluk hazırlandı. Örneklerin 12 tanesinin kök kanallarının son yıkaması için sırası ile 2 ml %17 EDTA 2 dakika boyunca, 2 ml %5,25'lik NaOCl ve son olarak 5 ml distile su kullanıldı. Diğer 12 tanesinin son yıkaması için 2 ml %17 EDTA 2 dakika boyunca, 2 ml %5,25'lik NaOCl, 2 ml distile su, 2 ml %2 CHX ve 5 ml distile su kullanıldı. Kök kanalları hazırlanmış her bir dişten korono-apikal yönde kesitlerin kalınlığı 1 mm olacak şekilde su soğutması altında 5 adet horizontal kesit alındı. Kesitlerin yarısına BioAggregate diğer yarısına ise X-tra base kompozit rezin uygulandı. Daha sonra örneklerin push-out bağlantı dayanımları ölçüldü. Elde edilen veriler Student-t testi ile istatistiksel olarak değerlendirildi (P < 0,05). Bulgular:İrrigasyon solüsyonun materyallerin bağlantı dayanımına istatistiksel olarak etki etmeği bulundu (P > 0,05). XTB grubunun irrigasyon solüsyon türüne bakılmaksızın BA grubundan istatistiksel olarak dentine daha yüksek bağlantı dayanımı gösterdiği tespit edildi (P < 0,05). Sonuç:Çalışmamızın sınırları dahilinde XTB bulk-fill kompozit rezininin pushout bağlantı dayanımının kalsiyum silikat esaslı BA simanından daha yüksek olduğu bulunmuştur.Anahtar sözcükler: BioAggregate, X-tra base, Push-out, EDTA, Klorheksidin. ABSTRACT Aim:To compare the push-out bond strength of BioAggregate cement and X-tra base composite resin and the effect of EDTA and chlorhexidine irrigation solutions on push-out bond strength of these materials. Material and Method:Twenty-four maxillary central incisor teeth were included to the study. Teeth were prepared up to apical diameter #40 using ProTaper Next rotary system. Than, a parallel post drill with 1.25 mm diameter was used to create a 10 mm long space. 12 of the samples were irrigated with 2 ml 17% EDTA for 2 minutes, 2 ml 5.25% NaOCl and 5 ml distilled water respectively. Other 12 of the samples were irrigated with 2 ml 17% EDTA for 2 minutes, 2 ml 5.25% NaOCl, 2 ml distilled water, 2 ml 2% CHX and 5 ml distilled water respectively.Geliş tarihi /
