Background and Purpose— Because of a shortage stroke specialists, many outlying or “spoke” hospitals initiate intravenous (IV) thrombolysis using telemedicine telephone consultation before transferring patients to regional center (RSC) hub. We analyzed complications outcomes treated with IV tissue plasminogen activator (tPA) the “drip ship” approach compared those directly at RSC. Methods— A retrospective review our Get With Guidelines Stroke (GWTG-Stroke) database from 01/2003 03/2008...
Finite element analysis (FEA) was used to investigate the influence of different post systems on stress distribution weakened teeth under oblique-load application. A maxillary central incisor root obtained from a sound tooth by partial removal dentin inside canal. Seven two-dimensional numerical models, one and six restored with composite resin were created as follows — ST: tooth; CPC: cast CuAl core; SSP: stainless steel + GP: fiberglass CP: carbon fiber ZP: zirconium dioxide TP: titanium...
Restoring flared endodontically treated teeth continues to be a challenge for clinicians. This study evaluated the effect of post types and restorative techniques on strain, fracture resistance, mode incisors with weakened roots. One hundred five bovine roots (15 mm) were divided into 7 groups (n=15). The two control (C) intact restored Cpc (cast posts core) or Gfp (glass fiber posts). experimental (F) GfpAp (Gfp associated accessory glass posts), GfpRc (anatomic Gfp, relined composite...
Abstract This study measured the radiant power (mW), irradiance (mW/cm2) and emission spectra (mW/cm2/nm) of 22 new, or almost light curing units (LCUs): - Alt Lux II, BioLux Standard, Bluephase G2, Curing Light XL 3000, Demetron LC, DX Turbo LED 1200, EC450, EC500, Emitter C, D, KON-LUX, 3M ESPE, Led Optilight Color, Max, Optilux 501, Poly Wireless, Radii cal, plus, TL-01, VALO Cordless. These LCUs were either monowave multiple peak emitting diode (LED) quartz-tungsten-halogen used in...
Abstract Aim To analyse the cytotoxicity, colour change and radiopacity of MTA Flow (MTA), UltraCal XS (UC) Bio‐C Temp (BT). Methodology Human dental pulp cells (hDPCs) stimulated with lipopolysaccharide (LPS) were placed in contact several dilutions culture media previously exposed to experimental materials tested for cell viability using MTT. Bovine teeth prepared simulate an open apex mimic extensive crown fracture. The roots filled a mixture agar blood, over this mixture. control group...
Given the increasing prevalence of individuals using charcoal-based dentifrices over extended periods without professional oversight, concerns have emerged regarding their potential effects. This study aimed to investigate influence different products on color change (ΔE00), gloss stability, and surface roughness dental enamel (Intact or bleached) resin composites subjected 12-month simulated brushing. 132 bovine crowns were randomly allocated restored with either SS-single-shade...
This in vitro study evaluated the impact of over-the-counter (OTC) products on optical properties (color and gloss changes) mechanical (shear bond strength) tooth enamel subjected to a simulated orthodontic treatment. 80 bovine teeth were selected staining protocol initial color assessments. Then, brackets bonded center clinical crown each sample, underwent bleaching protocols. The samples allocated five groups (n=16): Conventional in-office 35% Hydrogen peroxide - positive control (HP35);...
To analyse the discolouration, radiopacity, pH and calcium ion release of Biodentine (BD), Bio-C repair (BCR) temp (BCT), as well their biological effects on human dental pulp cells (hDPCs).Sixty-four extracted bovine incisors were prepared to simulate crown fractures with exposure open root apex. The roots filled using a mixture agar blood (control), BD, BCR or BCT placed over this mixture. Colour assessment analyses samples performed before immediately after material insertion repeated at...
This study aimed to analyze the microhardness (KHN) and diametral tensile strength (DTS) of two hybrid resin composites (TPH Spectrum Filtek Z250). To this end, were polymerized with six laboratory photo-curing units (LPUs) results compared an alternative polymerization method using conventional halogen light source in conjunction additional autoclave (15 minutes/100°C). LPUs used following manufacturers' instructions. Diametral Knoop hardness tests conducted for all groups (n=5). Data...
The esthetic and functional rehabilitation of patients with multiple missing teeth can be performed several techniques materials. Ceramic restorations provide reliable masticatory function good esthetics. However, fracture occur in some cases due to their brittle behavior. In cases, the replacement an extensive prosthesis is a problem high treatment cost. this paper, two are presented, which fractures occurred metal-ceramic fixed partial dentures, was not possible. repair chosen sequences...
Abstract This study investigated the effects of oxygen inhibition and finishing/polishing procedures on composite resin properties. One bulk-fill two conventional resins (nanoparticle microhybrid) were evaluated. Specimens prepared using 4 surface treatments: control, no treatment; Gly, with glycerin; FP, finishing polishing; Gly + glycerin followed by polishing. The degree conversion (DC) was measured Fourier Transformed Infrared Spectroscopy (FTIR) immediately after 15 days (n=5). Color...
This study evaluate the use of bovine teeth as a substitute for human on fracture strength tests composite fixed partial dentures (Cpd), with and without fiberglass reinforcement (Fg). Eighty were selected, being 40 incisors, 20 premolars molars. Bovine incisors ground to get platform, simulating an occlusal surface molar. Teeth in pairs embedded polystyrene resin, periodontal ligament divided 4 groups: B-Cpd-Fg: restored Cpd Fg; B-Cpd-NFg: H-Cpd-Fg: H-Cpd-NFg: Fg. The adhesively submitted...
This in vitro study analyzed the effect of different load application devices on fracture resistance and failure mode maxillary premolars restored with composite resin. Sixty human received standardized mesio-occluso-distal cavity preparations were The specimens randomly divided into 6 groups (n=10). Compressive loading was applied using metallic devices: S2: 2-mm sphere; S6: 6-mm C2: cylinder; C6: WS: wedge shape device; MAT: individualized antagonist tooth. Data statistically one-way ANOVA...
Abstract Objective This laboratory randomized study was designed to evaluate the effect of polishing on roughness and color stability bleached teeth after coffee immersion. Materials Methods Ninety bovine crowns were randomly allocated six groups ( n = 15), according bleaching protocols: At‐home: standard protocol using 10% hydrogen peroxide (HP) or In‐office: 35% HP; with (1) no polishing, (2) enamel polished #0.5 μm (3) #2–4 diamond particles grit pastes. Samples daily immersed into...
The aim of this study was to evaluate the microtensile bond strength (µTBS) two substrates (enamel and dentin) considering factors: type composite resin [methacrylate-based (Filtek Supreme) or silorane-based LS)] aging time (24 h 3 months). Twenty human molars were selected divided into 2 groups (n=10) dental substrates, enamel dentin. dentin each tooth halves separated by a glass plate. Each restored using both tested resins following manufacturer's instructions. samples sectioned,...
Aim: The development of postoperative pain following root canal instrumentation may impair patient’s comfort and undermine their trust in the dentist.
