Objectives To study the surface properties of polyetheretherketone (PEEK) and its bond strength with two veneering resins after different conditioning methods as well fracture load PEEK three-unit fixed dental prostheses (FDPs). Methods Two hundred twenty five specimens were fabricated divided into groups: no treatment (A), etching 98% sulfuric acid for 1 min (B), air-abrasion 10 s either 50 or 110 μm alumina (C D, respectively), silica coating using Rocatec System (E). On 15 each method,...
Aims To explore drug exposure, frequency of adverse reactions (ADRs), types ADRs, predisposing risk factors and ADR‐related excess hospital stay in medical inpatients. Methods Structured data regarding patient characteristics, ‘events’ (symptoms, laboratory results), diagnoses (ICD10) therapy were collected using a computer‐supported entry system an interface for retrieval from electronic records. ADR by ‘event monitoring’ to minimize possible bias the monitor. The causality each event was...
This study tested whether the two-body wear of monolithic zirconia and their corresponding enamel antagonists was higher compared to alloy veneered zirconia.Cylindrical specimens (N = 36, n 6) were prepared out (A) (VZ), (B) glazed using a glaze ceramic (GZC), (C) spray (GZS), (D) manually polished (MAZ), (E) mechanically (MEZ) (F) base (control group, MA). Wear tests performed in chewing simulator (49 N, 1.7 Hz, 5°C/50°C) with antagonists. The analysis 3D profilometer before after 120,000,...
Generalized linear mixed models (GLMMs) enjoy increasing popularity because of their ability to model correlated observations. Integrated nested Laplace approximations (INLAs) provide a fast implementation the Bayesian approach GLMMs. However, sensitivity prior assumptions on random effects precision parameters is potential problem. To quantify assumptions, we develop general measure based Hellinger distance assess posterior distributions with respect changes in for parameters. In addition,...
This study determined the discoloration of five CAD/CAM resins, four manually polymerized and glass-ceramic as control group. Specimens were divided into three groups (N=300, n=30) to be stored in coffee, black tea red wine (n=10). The was measured using a spectrophotometer after 1, 7, 29, 90, 180 days storage. All tested showed color change (ΔE) at all time points. resin composites GD (Gradia) CM (CronMix K), composite HC (Blanc High-class) significantly higher ΔE compared other media....
This study tested tensile bond strength (TBS) between veneering resins and polyetheretherketone (PEEK) after pre-treatment with adhesive systems. Five-hundred-seventy-six PEEK disks were fabricated, air-abraded divided into six groups (n=96/group): Z-Prime Plus, Ambarino P60, Monobond Visio.link, Signum Bond, control group without pre-treatment. Each was three subgroups of different (n=32): Sinfony, GC Gradia VITA VM LC. After specimen preparation a area 6.6 mm(2), half each subgroup (n=16)...
PURPOSE: To test the impact of mechanical and chemical treatments PEEK on surface roughness (SR), free energy (SFE), tensile bond strength (TBS) to veneering resin composites. MATERIALS AND METHODS: specimens (N = 680) were fabricated divided into treatment groups (n 170/group): 1. air abrasion (AIA); 2. etching with piranha solution (PIS); 3. + acid (AIP); 4. no (NO). Ten each group assessed a contact angle measuring device profilometer determine SFE SR, respectively. The remaining 160...
Background: The well-being of breast cancer patients and reporting adverse events require close monitoring. Mobile apps allow continuous recording disease- medication-related symptoms in undergoing chemotherapy. Objective: aim the study was to evaluate effects a mobile app on patient-reported daily functional activity supervised unsupervised setting. Methods: We conducted randomized controlled 139 Patient status self-measured using Eastern Cooperative Oncology Group scoring Common...
Background. Transplant recipients (TR) have a dramatically increased risk for widespread epithelial neoplasms of the skin. Thus, there is need to treat initial stages these such as actinic keratoses (AK) and Bowen's disease (BD) prevent progression invasive potentially fatal squamous cell carcinoma. Topical photodynamic therapy (PDT) has been proven be an effective treatment AK BD in immunocompetent patients, but no prospective trials immunocompromised TR performed so far. Methods. Twenty 20...
The aim of this clinical study was to compare the internal gaps between abutment teeth and posterior fixed partial dentures (FPDs) fabricated utilizing milled zirconia cast gold-alloy frameworks. As part an ongoing randomized controlled trial, 32 three-unit FPDs (16 16 metal-ceramic) in 25 patients were randomly selected for adaptation measurements. During bisque-stage ceramic try-in, A-silicone impression material placed framework. gap, corresponding thickness replica, measured under...
Abstract Objectives: The aim of the present study was to test whether or not immediate implantation leads more biological complications, when performed at extraction sockets teeth exhibiting periapical pathology compared with pathology. Materials and methods: In 17 consecutively admitted patients, implant placement planned in order replace single (test group). These demonstrated pain, radiolucency, fistula, suppuration a combination these findings. Another patients need tooth replacement...
This study investigated the contrast ratio and grain size depending on sintering parameters of twelve different zirconia materials compared with glass-ceramic (N=156, n=12 per group). Contrast all ceramics was measured using a spectrophotometer according to ISO 2471: 2008. Grain sizes were determined by SEM. Data analyzed one-way ANOVA followed post-hoc Scheffé-test, Kruskal-Wallis-H-test Spearman correlation (p<0.05). The area under curve up 25°C (AUC25) 1200°C (AUC1200) calculated....
This study tested the impact of different adhesives and resin composite cements on shear bond strength (SBS) to polymethyl methacrylate (PMMA)- composite-based CAD/CAM materials. SBS specimens were fabricated divided into five main groups (n=30/group) subject conditioning: 1. Monobond Plus/Heliobond (MH), 2. Visio.link (VL), 3. Ambarino P60 (AM), 4. exp. VP connect (VP), 5. no conditioning-control group (CG). All cemented using a. Clearfil SA Cement b. Variolink II stored in distilled water...
