“…As other researchers have reported, MTA can induce bone generation, as confirmed by the results of the current study (10, 23, 33–35). Nano-WMTA was supposed to accelerate the bone-healing process, and it exhibited a better response in the bone-healing process when nano–tricalcium aluminate was added to it.…”

“…Liu et al (23) studied the formation of hydroxyapatite (HA) on C 3 S/C 3 A mixtures derived from MTA. Their results verified that the C 3 S/C 3 A mixtures could induce the formation of an HA layer on their surface in SBF, contributing to in vitro bioactivity.…”

“…The addition of C 3 A to C 3 S, (Ca 3 SiO 5 )/C 3 A mixtures, which are derived from MTA, has been shown to accelerate the hydration process. As a result, the setting time significantly reduces, compressive strength increases, and the mixtures assumes similar bioactivity and biocompatibility when compared with pure C 3 S (23). The aim of this study was to evaluate the bone response to the implantation of Nano-WMTA (patent application #13/211.880), WMTA, WMTA without C 3 A, and Nano-WMTA + 2% Nano-C 3 A in the mandible of rabbits by using serial DXA measurement.…”

Introduction Materials with new compositions were tested in order to develop dental materials with better properties. Calcium silicate–based cements, including white mineral trioxide aggregate (WMTA), may improve osteopromotion because of their composition. Nano-modified cements may help researchers produce ideal root-end filling materials. Serial dual-energy x-ray absorptiometry measurement was used to evaluate the effects of particle size and the addition of tricalcium aluminate (C3A) to a type of mineral trioxide aggregate–based cement on bone mineral density and the surrounding tissues in the mandible of rabbits. Methods Forty mature male rabbits (N = 40) were anesthetized, and a bone defect measuring 7 × 1 × 1 mm was created on the semimandible. The rabbits were divided into 2 groups, which were subdivided into 5 subgroups with 4 animals each based on the defect filled by the following: Nano-WMTA (patent application #13/211.880), WMTA (as standard), WMTA without C3A, Nano-WMTA + 2% Nano-C3A (Fujindonjnan Industrial Co, Ltd, Fujindonjnan Xiamen, China), and a control group. Twenty and forty days postoperatively, the animals were sacrificed, and the semimandibles were removed for DXA measurement. Results The Kruskal-Wallis test followed by the Mann-Whitney U test showed significant differences between the groups at a significance level of P < .05. P values calculated by the Kruskal-Wallis test were .002 for bone mineral density at both intervals and P20 day = .004 and P40 day = .005 for bone mineral content. Conclusions This study showed that bone regeneration was enhanced by reducing the particle size (nano-modified) and C3A mixture. This may relate to the existence of an external supply of minerals and a larger surface area of nano-modified material, which may lead to faster release rate of Ca2+, inducing bone formation. Adding Nano-C3A to Nano-WMTA may improve bone regeneration properties.

“…Figure 6 (A) indicates that PSC-55 contained a substantial amount of C3A, exhibiting a statistically significant difference in the LDH assay compared with the other groups at 1 day and 3 days of incubation. Liu et al determined that adding 0%–15% C3A into C3A and C3S mixtures yields no significant cytotoxicity within the extract concentration range between 3.125 mg/mL and 100 mg/mL [34]. The extract concentration in this study was 100 mg/mL and, according to the results of the cell viability assay, all of the PSCs exhibited no cytotoxicity and did not influence cell function for a long period of time.…”

Background/PurposeMineral Trioxide Aggregate (MTA) was widely used as a root-end filling material and for vital pulp therapy. A significant disadvantage to MTA is the prolonged setting time has limited the application in endodontic treatments. This study examined the physicochemical properties and biological performance of novel partially stabilized cements (PSCs) prepared to address some of the drawbacks of MTA, without causing any change in biological properties. PSC has a great potential as the vital pulp therapy material in dentistry.MethodsThis study examined three experimental groups consisting of samples that were fabricated using sol-gel processes in C3S/C3A molar ratios of 9/1, 7/3, and 5/5 (denoted as PSC-91, PSC-73, and PSC-55, respectively). The comparison group consisted of MTA samples. The setting times, pH variation, compressive strength, morphology, and phase composition of hydration products and ex vivo bioactivity were evaluated. Moreover, biocompatibility was assessed by using lactate dehydrogenase to determine the cytotoxicity and a cell proliferation (WST-1) assay kit to determine cell viability. Mineralization was evaluated using Alizarin Red S staining.ResultsCrystalline phases, which were determined using X-ray diffraction analysis, confirmed that the C3A contents of the material powder differed. The initial setting times of PSC-73 and PSC-55 ranged between 15 and 25 min; these values are significantly (p<0.05, ANOVA and post-hoc test) lower than those obtained for MTA (165 min) and PSC-91 (80.5 min). All of the PSCs exhibited ex vivo bioactivity when immersed in simulated body fluid. The biocompatibility results for all of the tested cements were as favorable as those of the negative control, except for PSC-55, which exhibited mild cytotoxicity.ConclusionPSC-91 is a favorable material for vital pulp therapy because it exhibits optimal compressive strength, a short setting time, and high biocompatibility and bioactivity.

İki aşamalı adeziv Prime&Bond NT (Dentsply De Trey) dentine uygulandı ve 20 saniye bekletildi, daha sonra 5 simanların dayanıklılığında önemli bir rolü olduğu bildirilmiştir (20,21). BA sahip olduğu düşük pushout bağlantı değeri simanda eksik olan alüminyumdan kaynaklanıyor olabilir.…”

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 /
