ABSTRACT Introduction: It is recently suggested that titanium dioxide (TiO2) nanoparticles can be added to bracket luting agents in order to reduce bacterial activity and protect the enamel. However, it is not known if this addition can affect the shear bond strength (SBS) below clinically acceptable l...
Objetivo: Avaliar e comparar a rugosidade superficial e a atividade dos osteoblastos em contato com uma nova superfície bioativa e nanoestruturada de titânio grau 4 revestida com vidro bioativo contendo fosfato de cálcio, sintetizada pelo método sol-gel. Material e método: Sessenta e três discos...
El tratamiento de las fracturas costales debe ser individualizado de acuerdo con la severidad de las lesiones y a la magnitud del trauma. El objetivo de esta investigación es presentar un caso donde se utilizaron láminas de titanio, en un paciente con fracturas múltiples de las costillas. Se reporta e...
ABSTRACT Objective: To identify the appropriate power level for electric welding of three commercial brands of nickel-titanium (NiTi) wires. Methods: Ninety pairs of 0.018-in and 0.017 × 0.025-in NiTi wires were divided into three groups according to their manufacturers - GI (Orthometric, Marília, B...
Abstract The aim of the present study was to evaluate the cyclic fatigue of two anatomic finishing files: XP-Endo Finisher and XP-Clean. Roughness pattern and the micro-hardness of the files were also assessed. Instruments were subjected to cyclic fatigue resistance measuring the time to fracture in an a...
Abstract Purpose: To compare the influence of two metallic implants in the diagnosis of periprosthetic infection using 99m technetium-labeled ceftizoxime. Methods: Twenty rats were randomly divided into four groups, which received sterile and contaminated titanium and stainless steel implants. After 3...
