We therefore retrospectively reviewed 68 consecutive with 102 idiopathic clubfeet treated by technique four Portuguese hospitals. followed patients a minimum 30 months (mean, 41.4 months; range, 30-61 months). were divided into two groups according their treatment; Group I was younger than...

ResumoA eclâmpsia é uma complicação grave dos distúrbios hipertensivos da gravidez, associada a significativa morbidade e mortalidade materna fetal. Sua gênese está relacionada à pré-eclâmpsia, caracterizada por hipertensão proteinúria após vigésima semana de gestação. Este estudo revisou avanços no manejo na prevenção eclâmpsia. A utilização do sulfato magnésio (MgSO4) para controle convulsões demonstrou eficácia, sendo complementada com agentes como labetalol hidralazina. Intervenções...

Color stability of acrylic resins is essential for preserving the aesthetic appearance denture bases over time. This study explores how food pigments and thermal changes affect color commonly used base resins. Four were tested: three heat-cured with different characteristics (Zhermack® Villacryl H Plus V2, V4, Rapid FN V4) one self-cured resin S V4). To simulate oral environment, underwent 1000 cycles between 5 °C 55 °C, followed by a 7-day immersion period in beverages such as coffee, red...

This study evaluated if the material, substrate, and cement have no influence on color of pre-shaded monolithic zirconia crowns. The specific effect over each substrate/brand group was also studied. Two commercial brands zirconia, Amann Girrbach (AG) Zirkonzahn (ZZ), were used to produce crowns that placed three substrates (natural tooth, metal) using two different resin cements (Ivoclar AG (Shaan, Liechtenstein) Neutral Light) or glycerol (as control) (n = 10). Lightness (L*), chroma (C*),...

Specimens submitted to Vickers microhardness 3-point loading strength...

The aim of this review was to evaluate if the properties digitally produced dental acrylic resins improved when reinforced with compounds. A literature search conducted in PubMed, Web Science, and Scopus databases for past 10 years. Combinations keywords were chosen reflect PICO question: Do loaded compounds have better mechanical, surface and/or biological than without compounds? selection carried out by two independent researchers according PRISMA flowchart specific eligibility criteria....

The purpose of this study was to evaluate the retentive forces over time removable partial denture clasps fabricated by digital method. Occlusal rest seats were on three premolar teeth fixed in acrylic blocks (9 × 20 40 mm). Digitization performed using a laboratory scanner (Zirkonzahn Scanner S600 GmbH, Gais, Italy). After analysis and determination insertion axis, two types with mesial occlusal rests designed per tooth: back-action reverse clasps, Partial Planner Zirkonzahn program. file...

Objectives: To assess the effect of a CAD-CAM protocol fabrication on clinical fit accuracy removable partial denture metal frameworks to abutment teeth. Methods: Fifteen patients with edentulism were selected participate in this study, and twenty dental arch rehabilitations planned. For each (n=20), two cobalt-chromium produced through protocols: production (experimental group); conventional lost-wax casting technique (control group). Clinical was assessed using an indirect quantitative...

Changes in the properties of resin-based polymers exposed to oral environment can emerge when chlorhexidine (CHX) is incorporated develop bioactive systems for treating denture stomatitis. Three reline resins loaded with CHX were prepared: 2.5 wt% Kooliner (K), 5 Ufi Gel Hard (UFI), and Probase Cold (PC). A total 60 specimens submitted physical aging (1000 cycles thermal fluctuations, 5–55 °C) or chemical (28 days pH fluctuations artificial saliva, 6 h at = 3, 18 7). Knoop microhardness (30...

The high recurrence rate of common denture stomatitis after antifungal treatment is still concerning. This condition caused by low patient compliance and incomplete local elimination the main etiological factor - Candida albicans, often associated with other microorganisms, such as Streptococcus species. Impregnating materials antimicrobials for delivery a strategy that can overcome side effects improve efficacy conventional treatments (topical and/or systemic). In this work, we describe...

Acrylic bone cement (BC) is used in orthopaedic surgery to anchor cemented prostheses bone. Association of antioxidant molecules BC may suppress reactive species injury which contributes implant failure. Tocopherol acetate (ATA)-loaded polymethylmethacrylate (PMMA) particles (ATA(PMMA)) were prepared by single emulsion solvent evaporation technique and incorporated into BC. An encapsulation efficiency 84% (w/w) was obtained drug release studies showed distinct ATA profiles mechanisms before...
