Color Change of Different Dual-Cure Resin Cements After Thermocycling

Odovtos (En línea); 21 (2), 2019
ABSTRACT The purpose of this study is to evaluate the effect of thermocycling on the color change of the amine-free dual-cure resin cements. IPS e.max CAD blocs were cut into specimens of 1 mm thickness (N=28) and cemented with one of the 4 different amine-free dual-cure resin cements (NX3 Nexus [NX], Ke...

Six month follow-up of two bulk-fill composites in non-carious cervical lesions: double blind randomized clinical trial

J. oral res. (Impresa); 8 (3), 2019
Objective: To assess the six-month clinical outcome of restorations of non-carious cervical lesions (NCCL) with two composite resins: Bulk-Fill and nanohybrid resin. Materials and methods: Fifty-one patients, with three NCCLs each, were randomly allocated into three restoration groups: Tetric-N-Ceram Bul...

Effect of glass fiber post adaptation on push-out bond strength to root dentin

Braz. dent. j; 30 (4), 2019
Abstract The aim of this study was to evaluate the effect of different glass fiber posts (GFPs) diameters on the push-out bond strength to dentin. Forty unirradicular human teeth were endodontically treated and used for cementation of GFPs (White Post DC, FGM) with different diameters (n=10): P1 - ø 1.6...

Influence of pre-curing different adhesives on the color stability of cemented thin ceramic veneers

Braz. dent. j; 30 (3), 2019
Abstract The objective was to evaluate the color stability of thin ceramic veneers as a function of the curing mode (with and without pre-cure) of different adhesive systems applied to the internal surface of ceramics. Five adhesive systems (Scotchbond Multi-Purpose, Single Bond Universal, Gluma 2 Bond, ...

Comparación in vitro del espesor y homogeneidad de la capa de cementación en carillas indirectas, realizado con resina fluida vs cemento de resina fotodependiente

Odontol. vital; (30), 2019
Resumen Objetivo: Comparar el grosor y homogeneidad de la capa de cementación entre un cemento de resina fotodependiente y una resina fluida. Materiales y métodos: Para la obtención de la muestra se talló la preparación en un diente de marfilina, el cual fue escaneado y luego replicado 92 veces en...

Comparación de la fuerza de unión y la integridad marginal con compuestos de resina de relleno masivo y compuestos indirectos
Comparing bond strength and marginal integrity with direct bulk-fill resin composites and indirect composites

Rev. cuba. estomatol; 56 (2), 2019
ABSTRACT Introduction: The clinical longevity of tooth restoration -whether directly or indirectly using composites- greatly depends on the quality and stability of the marginal adaptation. Even today, dental restoration failure is a major complication in everyday dental practice. Objective: To evalua...

Effect of self-etching primer associated to hydrofluoric acid or silane on bonding to lithium disilicate

Braz. dent. j; 30 (2), 2019
Abstract To evaluate the effect of combining 5% hydrofluoric acid (HF) and silane (SI) with the self-etching ceramic primer on the immediate and after 1-year of water storage on bonding efficacy, conditioning pattern (CP) and chemical interaction (CI) to the lithium disilicate. A total of 16 CAD/CAM bloc...

Do irrigation solutions influence the bond interface between glass fiber posts and dentin?

Braz. dent. j; 30 (2), 2019
Abstract The aim of this study was to evaluate the push-out bond strength and interface permeability of glass-fiber posts in different regions of post space (cervical, middle, and apical) submitted to different irrigation solutions. Ninety single-rooted human teeth were submitted to endodontic treatment ...

Concepts and techniques to improve resin/resin bonding: literature review

The availability of new scientific information about the etiology, diagnosis and treatment of carious lesions and the introduction of reliable adhesive restorative materials substantially reduced the need of extensive tooth preparations. In order to achieve a successful procedure,...
