The use of high-concentration sodium hypochlorite (NaOCl) as an endodontic irrigant remains controversial because its potential impact on the fracture strength endodontically treated teeth. This study evaluated effects using different NaOCl concentrations, with 2-min-ethylenediaminetetraacetic acid (EDTA) final active irrigant, biomechanical and structural properties root dentine.A new test method, which is more clinically relevant, was utilized to calculate dentine. Bovine incisors were...
In this study, a novel dental composite based on the unsaturated bismethylene spiroorthocarbonate expanding monomer 3,9-dimethylene-1,3,5,7-tetraoxa-spiro[5,5]undecane (BMSOC) and bisphenol-S-bis(3-meth acrylate-2-hydroxypropyl)ether (BisS-GMA) was prepared. CQ (camphorquinone) of 1 wt % DMAEMA (2-(dimethylamino)ethyl methacrylate) 2 were used in photoinitiation system to initiate copolymerization matrix resins. Distilled water contact angle measurements performed for wettability...
Photoactivating dental resin composites have been the most prevailing material for repairing defects in various clinical scenarios due to their multiple advantages. However, compared other restorative materials, surface of resin-based is more susceptible plaque biofilm accumulation, which can lead secondary caries and restoration failure. This study introduced different weight fractions (1, 2, 5, 10, 15%) magnesium oxide nanoparticles (MgONPs) as antibacterial fillers into composites....
A new type of photocurable resin composite containing nano-MgO was synthesized in order to reduce the occurrence secondary caries. Different mass ratios (0 %, 1 2 4 8 %) were added into composites. The antibacterial properties powder and modified composites against Streptococcus mutans (S. mutans) detected by ring test film contact test, respectively. Compressive strength (CS) wear resistance determined a universal testing machine an abrasion machine. results indicated that activity superior...
Occlusal reconstruction is a critical intervention for patients with dental hard tissue defects, temporomandibular joint (TMJ) disorders, and jaw position abnormalities. Clinical efficiency outcomes of these procedures have improved advances in digital technologies. This case report aims to illustrate comprehensive workflow occlusal patient congenital dentition emphasizing the application technologies enhance treatment outcomes.
To tackle the degradation of sealing performance in nitrile butadiene rubber (NBR) seals due to material aging during long-term service, this study integrates experimental and molecular simulation methods elucidate mechanism. Experimental results reveal that contents C=C C=O functional groups significantly decrease aging, accompanied by enhanced hydrophobicity increased crosslink density NBR, indicating crosslinking reactions dominate process with participation groups. Quantum mechanics (QM)...
Chitosan (CS)/polylactic acid (PLA)/tripolyphotspate (TPP) nanosized microcapsules were prepared by emulsion-evaporation. The average diameter of the obtained was around 100-300 nm, and a homogeneous size distribution good dispersion observed. entrapment efficiency CS/PLA/TPP for rapamycin increased with increase in amount PLA. When ratio CS to PLA 80 20, reached highest (89.8 +/- 1.72%). It also observed that RAPA its at 20% addition dosage RAPA.

Eur J Oral Sci 2012; 120: 161–167. © 2012 This study evaluated effect stress distribution and fracture resistance A finite element analysis (FEA) model maxillary central incisor with a was established. Five variations were studied: (i) 1‐mm bevel (ii) 2‐mm bevel, (iii) plain chamfer, (iv) stair‐step (v) butt joints (a control configuration). All FEA...
Abstract Purpose This study aimed to develop and evaluate a simple, non‐destructive method for assessing the misfit passivity of implant‐retained prostheses frameworks. Materials Methods To simulate rehabilitation mandible posterior partially edentulous area using 3‐unit screw‐retained frameworks supported by two implants were fabricated divided into following five groups ( n = 10 in each group): OP one‐piece framework cast Co‐Cr with conventional (control‐group); sectioned welded laser...
Severely uneven occlusal attrition is thought to play an important role in the occurrence of spontaneous vertical root fracture (VRF), a frequent problem among Chinese people. This study evaluated influence slope related on stress condition. A finite element model mandibular first molar was established. Two different patterns were simulated 5 models: (A) sound tooth, (B) 0.5-1.5 mm and (C) 2-3 increased buccally, (D) (E) distally. static load 200 N applied vertically or angled at 45°...
This study evaluated the vertical misfit, passivity, and stress distribution after tightening screws of different prosthesis. Two implants were used to simulate rehabilitation partially edentulous mandible space from second premolar molar. 40 three-element screw-retained fixed dental prosthesis with distal cantilever fabricated divided into four groups according method production framework (n = 10): G1 conventional casting one-piece framework, G2 sectioned laser welding, G3 tungsten inert...
