Abstract The proper selection of polymerization cycle is important to prevent overheating of the monomer that could cause degradation, porosity and, consequently, deleterious effects on the denture base properties. Objective This study evaluated the porosity, water sorption and solubility of acrylic res...

Introduction: Filling ability of retrograde cavity and porosity are important properties for root-end filling materials and may be evaluated by using microcomputed tomography (micro-CT). Objective: To evaluate filling ability and porosity of root-end filling materials using microcomputed tomography (mic...
ABSTRACT With the aim of introducing permanent prostheses with main properties equivalent to cortical human bone, Ti-diamond composites were processed through powder metallurgy. Grade 1 titanium and mixtures of Ti powder with 2%, 5% and 10 wt% diamond were compacted at 100MPa, and then sintered at 1250°...
A técnica moderna de fundição laboratorial permite um maior controle das ligas metálicas se comparada aos processos utilizados antigamente. O processo de fundição apresenta muitas variáveis e exige experiência. Durante a transformação de fase do resfriamento, o metal sofre várias modificaçõe...
ABSTRACT Incorporation of antifungals in temporary denture soft liners has been recommended for denture stomatitis treatment; however, it may affect their properties. Objective: To evaluate the porosity of a tissue conditioner (Softone) and a temporary resilient liner (Trusoft) modified by minimum inhib...

A incorporação do diacetato de clorexidina em resinas macias para o reembasamento de próteses removíveis pode se tornar um método eficaz no combate à Candida albicans, principal agente causador da Estomatite Protética. Dessa forma, este trabalho teve como objetivo avaliar os efeitos da incorporaç...
Introduction: For presenting wide antibacterial activity, chlorhexidine (CHX) has been extensively used in dentistry and can be easily incorporated into the glass ionomer cement (GIC) and consequently released into the oral cavity. Aim: The aim of this study was porosity and compression strength of a GIC...
Background Cyclodextrin glucanotransferase (CGTase) from Amphibacillus sp. NPST-10 was covalently immobilized onto amino-functionalized magnetic double mesoporous core-shell silica nanospheres (mag@d-SiO2@m-SiO2-NH2), and the properties of the immobilized enzyme were investigated. The synthesis process o...
