“…The flowability of the sealers is an important property that can determine the extent of filling of anatomical irregularities and spaces between the main cone and accessory cones to improve the effectiveness of root canal fillings. 21,27,28 Previous studies also reported good results using Sealapex with regard to its sealing ability, 29 flowability, 30 and viscosity.…”

Abstract:The volume of sealer in the apical 1 mm of teeth filled using different techniques was evaluated by micro-commuted tomography (micro-CT). Sixty-four maxillary central incisors were prepared using NiTi rotary instruments. Teeth were randomly distributed into four groups according to root canal sealers (AH Plus, Endofill, Sealapex, and Sealer 26) and subdivided into two subgroups according to the filling techniques (active and passive lateral condensation; n = 8 each). Subsequently, teeth were examined using the 1174 SkyScan micro-CT device. Images were reconstructed using the NRecon software, and the sealer volume (mm 3 ) in the apical region was analyzed using the two-way ANOVA and post-hoc Student-Newman-Keuls test (α = 0.05). The lowest volume of sealer was observed in teeth filled with Sealapex (0.100 ± 0.009) and Endofill (0.103 ± 0.010). The highest volume was observed in teeth filled with AH Plus (0.112 ± 0.008) and Sealer 26 (0.109 ± 0.018) (p > 0.05). Regarding the filling technique, a lower sealer volume was observed using the active lateral condensation technique compared with that using the passive lateral condensation technique (0.100 ± 0.010 vs. 0.111 ± 0.012) (p < 0.05). Therefore, the lowest volume of sealer was observed in teeth filled with Sealapex and Endofill using the active lateral condensation technique.

“…Recently, an SB sealer (SBS) containing radiopaque zirconium oxide was developed as a root-canal sealer. 8 This modified type of SB adheres to root canal dentine and is supposed to seal the root-canal system more effectively by forming a resin-impregnated layer. 7 Several studies have examined the cytotoxicity and tissue responses after SB application in vitro and in vivo.…”

Background/purpose: Adhesive resin sealer systems are applied to seal root-canal systems more effectively through the formation of a resin impregnation layer. The purpose of this study was to investigate the effects of eluted components of the adhesive, Super-Bond sealer (SBS), on the proliferation of osteoblastic cells in vitro. Materials and methods: The standard powder:liquid ratio according to the manufacturer's instructions was used to produce a cylindrical block of SBS (5 mm in diameter, 10 mm long) for this elution study. The resin block was placed on a 100-mm culture dish. Osteoblastic cells were seeded at a density of 4 Â 10 6 in a-minimum essential medium containing 10% fetal bovine serum and cultured in a humidified incubator. After 3 days of culture with or without SBS, cells were retrieved and lysed according to the manufacturer's instructions. The cellular events induced by the eluted components from SBS were analyzed using an antibody assay for mitogen-activated protein kinases (MAPKs) and a 3-(4,5-dimethylthyazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Furthermore, the concentration of boron, a component of the catalyst, tri-n-butyl borane (TBB), was analyzed using inductively coupled plasma optical emission spectrometry. Results: Expression of MAPKs increased after SBS application. The MTT assay indicated that TBB, one of the components of SBS, accelerated the proliferation of osteoblastic cells. Values of boron were 1.66 AE 0.37 and 1.74 AE 0.30 ppm in cells cultured with and without FBS, respectively. Journal of Dental Sciences (2012) 7, 94e98 Conclusions: The eluted components from SBS can increase the expression of some MAPKs related to osteoblastic cell proliferation and differentiation in vitro. Both the elution experiment and treatment of cell culture with SBS components indicated that the boron originating from TBB is likely to be responsible for activation of the proliferation of osteoblastic cells.

ÖZAmaç: Bu çalışmanın amacı, farklı apikal çaplara sahip (1mm ve 1.4mm) immatur dişlere ortograd ve retrograd yollarla, farklı uygulama teknikleri ile yerleştirdiğimiz MTA'nın apikal sızıntılarının bilgisayarlı sıvı filtrasyon tekniği ile belirlenmesidir. Gereç ve yöntem: Çalışmada kullanmak için toplamda 100 adet çekilmiş üst çene keser insan dişi kullanıldı. Açık apekse sahip immatür dişleri simüle etmek amacıyla apikal foramen, çapı 1mm ve 1.4 mm genişliğinde olacak şekilde prepare edildi. Üretici firmanın talimatları doğrultusunda karıştırılan MTA dört farklı yolla (retrograd yolla, ortograd yolla, 2 aşamalı ortograd yolla ve internal matrix destekli ortograd yolla) farklı apikal foramen çapa sahip kök kanallarının içerisine yerleştirildi. Dişler bilgisayarlı sıvı-filtrasyon cihazında mikrosızıntı testi için hazırlandı. Sızıntı çalışmasındaki her bir örnekteki sıvı hareketi ölçümleri 15 saniye aralıklarla 8 kez tekrarlandı ve bu ölçümlerin ortalama değerleri kaydedildi [ µl / (dk * cmH2O * cm2) ]. Sızıntı deneylerinden elde edilen verilerin istatistiksel analizinde SPSS 20 programı kullanıldı. Bulgular: Elde edilen veriler tek yönlü ANOVA ve post-hoc Tukey testleri kullanılarak analiz edildi. Gruplar arasında istatistiksel fark bulundu. En az sızıntı internal matrix in 1mm genişlikte ortograt uygulanan grupta görüldü. En fazla sızıntı ise1.4mm açıklığa sahip dişlerde retrograt uygulamada gözlendi. MTA'nın internal matrix ile birlikte kullanıldığı gruplarda ve MTA'nın iki aşamalı yerleştirildiği gruplarda sızıntı miktarı MTA'nın tek seferde yerleştirildiği gruplardan daha azdır. Sonuç:Çalışmamızda uyguladığımız ortograt prosedürde internal matrix ile birlikte MTA uygulandığında apikal sızıntı değerleri en azdır. Klinik olarak bu metodun tercih edildiği durumlarda, cerrahi uygulama sayıları azaltılabilir ve daha az invaziv uygulamalarla tedaviler yapılabilir. Anahtar Kelimeler: İmmatür diş, Mikrosızıntı, MTA, Sıvı filtrasyon ABSTRACT AimThe aim of this study is to determine the effect of apical foramen diameter, and different application methods on the sealing ability of MTA using computerized fluid filtration device. Material and methods: 100 extracted human teeth were used for this study. In our study, apical foramen were prepared diameter of 1-1.4 mm in width for to simulate the open apex with an immature teeth. MTA was mixed according to manufacturer's recommendations, and was placed into the root canals which have a different apical foramen diameter. by four different ways (retrograde way, two-phased ortograde way, and ortograde with or without internal matrix way). The teeth were prepared for the microleakage test with computerise fluid-filtration method. Measurements of fluid movement were made at intervals of 15-seconds and repeated 8 times and means of these measurements were recorded [ µl / (min * cmH 2 O * cm 2 ) ]. SPSS 20 software was used for statistical analysis of apical leakage of data. The data was analysed with one-way ANOVA and post-hoc Tukey tests. Results: The amount of leakage in groups ...
