Commercial mineral trioxide aggregate (MTA) materials such as Endocem MTA (EC), Dia-Root Bio (DR), RetroMTA (RM), and ProRoot (PR) are increasingly used root-end filling materials. The aim of this study was to assess compare the physicochemical mechanical properties cytotoxicity these MTAs. film thicknesses EC DR were considerably less than that PR; however, RM’s thickness greater PR. In addition, setting times EC, DR, RM shorter PR (p < 0.05). solubility not significantly different among...
In this study, mechanical properties of bioactive glass (BAG) synthetic bone graft substitute was improved by containing ZrO
Polyalkenoate cement (PAC) is a promising material for regenerative hard tissue therapy. The ionically rich glass component of PAC encourages bioactive interaction via. the release essential ions. However, bioactivity restricted owing to (i) structurally inherent cationic network formers and (ii) surface bacterial biofilm formation. These two factors cause deficiency in ion release, further complicated by secondary infections premature therapeutic failure. Here, multivalent zwitterionic...
The purpose of this study was to evaluate the change in retentive forces four different titanium-based implant attachment systems during simulation insert–removal cycles an artificial oral environment. Five types dental (Locator, Kerator, O-ring, EZ-Lock, and Magnetic) were studied (n = 10). specimens underwent saliva, force measured following 0, 750, 1500, 2250 cycles. Significant retention loss observed all systems, except magnetic attachments, upon completion insertion removal cycles,...
Despite numerous advantages of using porous hydroxyapatite (HAp) scaffolds in bone regeneration, the material is limited terms osteoinduction. In this study, scaffold made from nanosized HAp was coated with different concentrations osteoinductive aqueous methylsulfonylmethane (MSM) solution (2.5, 5, 10, and 20%) corresponding MH were referred to as MH2.5, MH5, MH10, MH20, respectively. The results showed that all resulted burst release MSM for up 7 d. Cellular experiments conducted MC3T3-E1...
Abstract As the technologies for treating diseases are attracting continuous attention, physical therapy methods, particularly electrical stimulation (ES), have been widely investigated owing to their high effectiveness. ES essentially requires an external power source, various efforts being devoted achieving application of human body using nanogenerators. Various studies verified effect by applying same output generated device in vitro and vivo bio‐electrical stimulation. However, it is...
Hybrid ionomer cements (HICs) are aesthetic polyelectrolyte that have been modified with a resin. The setting of HICs occurs by both monomer polymerization and an acid-base reaction. In addition, contain resin, which is substituted for water. Thus, the competition between reactions reduced water content inherently limits polysalt formation and, consequently bioactive interactions. this study, we explored effects polybetaine zwitterionic derivatives (mZMs) on augmentation response HICs....
본 연구의 목적은 치수복조 및 근관역충전재 등으로 사용될 수 있는 기혼합형 Mineral trioxide aggregate (MTA; Endocem MTA premixed regular, Maruchi, Gangwon-do, Korea)를 세 가지 유형의 용액; 유사생체용액(simulated body fluid, SBF), 0.9% 생리식염수(saline), 멸균증류수(distilled water, DW)에 7일 동안 침적 후 압축강도, pH, 그리고 표면 양상의 변화를 비교 분석하는 것이다. 시편을 각 용액에 1일과 간 침지 만능재료시험기를 이용하여 압축강도를 측정하였다. 이때, 침지하지 않은 MTA는 대조군으로 설정하였다. pH 분석을 위해, 침지하여 3, 6, 12, 24, 72시간, 168시간 meter를 또한, 용액으로 인한 시편의 관찰하기 위해 7일동안 SEM-EDS로 분석하였다. 통계 분석은 일원배치분산분석, Tukey's test 사후 검정, 독립 표본 T검정을...
Abstract 45S5 Bioglass (BG) is composed of a glass network with silicate based on the component and can be doped various therapeutic ions for enhancement hard tissue therapy. Nanoceria (CeO 2 ) has been shown to indicate redox reaction enhance biological response. However, few studies focus proportion CeO -doped its effect cellular bioactivity BG (CBG). In this study, we synthesized CBG series increasing amounts doping ranging (1 12) wt.%. The examined characterization, mineralization...
Despite numerous attempts to use human mesenchymal stem cells (hMSCs) in the field of tissue engineering, control their differentiation remains challenging. Here, we investigated possible applications a non-thermal atmospheric pressure plasma jet (NTAPPJ) hMSCs. An air- or nitrogen-based NTAPPJ was applied hMSCs culture media, either directly by media treatment which were plated after medium exposed NTAPPJ. The durations exposure 1, 2, and 4 min, not initial attachment assessed water-soluble...
