Desde os primordios da humanidade método e substâncias anestésicas são usadas em procedimentos cirúrgicos, diagnósticos terapêuticos, garantindo a ausência de dor. Assim sendo, destaca-se que antes qualquer procdimento, principalmente o cirurgico, uma avaliação deve ser feita devido aos riscos se usar substância anestesica. A pré-anestésica (APA) visa otimizar desfechos anestésico-cirúrgicos, permitindo coleta informações sobre estado clínico do paciente, solicitação exames complementares...
Interleukin-1 beta (IL1B) pathway is a key player in orthodontic-induced external apical root resorption (EARR). The aim of this work was to identify the genes related IL1 as possible candidate for EARR, which might be included an integrative predictive model complex phenotype.Using stepwise multiple linear regression model, 195 patients who had undergone orthodontic treatment were assessed clinical and genetic factors associated with %EARRmax (maximum %EARR value obtained each patient)....
The aim of this study was to compare intrapulpal temperature increase produced by high-speed handpiece, Er:YAG laser and CVDentus ultrasound tips during cavity preparation. Thirty bovine mandibular incisors with an enamel/dentin thickness 4 mm at buccal surface had their roots amputated were allocated the following groups (n=10): Group I- handpiece; II- noncontact (250 mJ/4 Hz); III- ultrasouns tips. All devices used water cooling. Class V cavities prepared a depth 3.5 mm, measured...
To compare the effect of silica (Si)-based nano-coating deposited by reactive magnetron sputtering (RMP) with that conventional surface conditioning using metal/zirconia primer alone or after air-particle abrasion on adhesion resin cements to zirconia ceramic.Two hundred forty ceramic blocks (Cercon) were sintered, finished 1200- grit SiC paper under water cooling, and cleaned ultrasonically in distilled for 10 min. The (4.5 mm x 3.5 4.5 mm) randomly divided into 24 groups (n = 10) according...
The influence of diamond-like carbon (DLC) films on bacterial leakage through the interface between abutments and dental implants external hexagon (EH) internal (IH) designs was evaluated.Film deposition performed by plasma-enhanced chemical vapor deposition. Sets (n = 30 per group, sets 180 implants) were divided according to connection design treatment abutment base: 1) no (control); 2) DLC film deposition; 3) Ag-DLC Under sterile conditions, 1 μL Enterococcus faecalis inoculated inside...
Abstract Objective The aim of this study was to investigate the effect hybrid abutment with different angles (0 and 15 degrees) on stress distribution deformation maxillary implant-supported fixed prosthesis, using digital image correlation (DIC) finite element analysis (FEA). Materials Methods For DIC, two situations were considered: conventional straight implant placement degrees inclination. Different zirconia mesostructures milled, one other a 15-degree angulation correct positioning....
Purpose. In case of need for esthetical improvement zirconia restorations, an individualization using extrinsic staining can be applied. This study aimed to evaluate the surface roughness and fatigue strength (survival) high-translucency (3Y-TZP, YZ®HT, Vita Zanhfabrik) with characterization and/or glaze. Methods. Sixty (60) discs (12 × 1.2 mm) were obtained, sintered, randomly distributed among three groups (n = 20) according finishing protocol: C (control), + G (extrinsic followed by a...
To determine the effect of maintaining torque after mechanical cycling abutment screws that are coated with diamondlike carbon and doped diamond nanoparticles, external internal hex connections.Sixty implants were divided into six groups according to type connection (external or hex) screw (uncoated, carbon, nanoparticles). The inserted polyurethane resin crowns nickel chrome cemented on implants. had a hole for access screw. initial measured. values maintained (in percentages) evaluated....
Background. New surface treatments have been proposed to expand the clinical indications of zirconia prostheses. This study aimed evaluate effect silica and fluorine nanofilms on ceramic resin cement bond strength. Methods. Zirconia blocks discs underwent different treatments: untreated (CON), sandblasted, silica-coated alumina particles (30 µm) (SC), nanofilm (SN), (FN). Nanofilm deposition was performed through plasma enhanced chemical vapor (PECVD). surfaces were characterized disks by...
ABSTRACT Aim This study assessed the effect of fatigue load cycling on human premolars restored with MOD restorations (direct and indirect approaches) cuspal deflection, compared to intact teeth (unprepared) unrestored an inlay preparation. Materials methods preparations were performed sixty their roots embedded in acrylic resin. These divided into six groups (n = 10): (1) teeth; (2) prepared (3) direct composite resin; (4) (5) injected ceramic inlays (IPS Empress 2 (Ivoclar); (6) CAD/CAM...
To simulate biodegradation and wear of stained glazed CAD lithium disilicate ceramic, evaluate their effects on the microbial adherence mechanical surface properties ceramic.160 ceramic discs were fabricated divided in eight groups according to manual stain glaze application with a fine paint brush (without glaze; glaze) aging procedures (no aging; at 30 N load, 1.7 Hz, 3 × 105 cycles; by exposure microcosm biofilm; + wear; wear). Profilometry was performed determine roughness consequences....
This study evaluated the influence of deposition parameters for Si-based thin films using magnetron sputtering coating zirconia and subsequent adhesion resin cement. Zirconia ceramic blocks were randomly divided into 8 groups specimens either ground finished polished or conditioned air-abrasion with alumina particles coated silica. In remaining groups, film argon/oxygen discharge at 8:1 20:1 flux. one group, was performed on air-abraded surfaces. After application bonding agent, cement...
Minimizar discrepância de assentamento tem sido a razão muitas pesquisas nos últimos tempos, visando melhorar qualidade adaptação das próteses dentárias. Entretanto, respeitados autores têm relatado resultados apresentando valores aparentemente incoerentes, isto é, melhor vertical coroas totais após cimentação, quando, devido à ausência cimento interposto o inverso seria esperado. Este fato levou- desenvolver presente trabalho. Assim, um dispositivo mecânico foi desenvolvido para padronizar...
To analyze the effect of a silicon (Si)-based film deposited on yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) topography and bond strength resin cement.Specimens were obtained randomly divided into 4 groups, according to surface treatment: polished group (PG) zirconia; sandblasted (SG) with aluminum oxide (100 µm); after polished, was coated Si-based (SiFG); sandblasted, (SiFSG). The films through plasma-enhanced chemical vapor deposition. Surface roughness contact angle analysis...
The loosening or fracture of the prosthetic abutment screw is most frequently reported complication in implant dentistry. Thin diamond-like carbon (DLC) films offer a low friction coefficient and high wear resistance, functioning as solid lubricant to prevent weakening implant–abutment system. This study evaluated effects DLC nanofilms on reverse torque abutments after simulated chewing. Abutments with 8° 11° taper connections, without silver-doped coatings, were tested. deposited through...
