Zinc oxide-eugenol (ZOE) is usually applied clinically as dental filling material for thermal insulation and temporary restoration. The objective of this study was to use ZOE as a composite matrix and low melting-point polyester fibers or fabrics as reinforcement. The added fibers or fabrics increased the composite materials’ compressive load by 250 N and 290 N, respectively. Fiber length and t...

The purpose of this study was to evaluate in vitro the antimicrobial activity of materials used as root canal filling in deciduous teeth by direct exposure test. The materials tested were: Guedes-Pinto, CTZ, zinc oxide eugenol, Calen, L&C and MTA pastes. A microbial mixture was prepared with 1 mL each of pure suspension of the following microorganisms: Staphylococcus aureus, Enterococcus faeca...

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B)...

BackgroundIn this study, zinc oxide nanoparticles-coated with eugenol (ZnO@Eug) were synthesized and evaluated as a nanosuspension (NSus) formulation against Toxoplasma gondii in vitro vivo.MethodsAn anti-Toxoplasma activity assay for ZnO@Eug NSus was conducted vitro, ex vivo, vivo. FTIR spectroscopy confirmed the formation of by detecting several functional groups involved; EDX SEM demonstrate...

OBJECTIVE The aim of this study was to determine whether a dentine bonding agent (DBA) had an effect in reducing fluid filtration under cemented provisional crowns. METHODS Crown preparations on 34 premolars, randomly allocated to two equal-sized test and control groups, were assessed for dentine permeability by a fluid filtration technique. In the test group, prepared crowns were acid-etched...
