Color stability in a giomer, a conventional glass ionomer and a resin-modified glass ionomer exposed to different pigment beverages: An in vitro comparative study
(Journal of International Oral Health, 2023-08-31)Acceso abiertoAim: Discoloration in ionomeric materials occurs by absorption of substances, so color stability is important because these materials are of choice to restore class V. The purpose of the current study was to evaluate the ... -
Estabilidad del color de un giómero y dos ionómeros de vidrio, uno convencional y otro modificado con resina, expuestos a diferentes bebidas pigmentantes
(Universidad Privada San Juan Bautista, 2024-02-22)Acceso abiertoLos materiales ionoméricos sufren de decoloración a causa de la absorción de ciertas sustancias, por eso la estabilidad de color es fundamental ya que este material es de suma importancia para restauraciones clase v. ... -
In Vitro Color Stability Evaluation of Three Polished and Unpolished Nanohybrid Resin Composites Immersed in a 0.12% Chlorhexidine-Based Mouthwash at Different Times
(Polymers, 2023-03-07)Acceso abiertoAbstract: The use of chlorhexidine-based mouthwashes on resin composites with rough surfaces can cause discoloration which compromises the esthetic of patients. The present study aimed to evaluate the in vitro color ... -
Surface roughness and oxygen inhibited layer control in bulk‑fll and conventional nanohybrid resin composites with and without polishing: in vitro study
(BMC Oral Health, 2022-06-26)Acceso abiertoBackground: It has been demonstrated that dental restorations with rough surfaces can have several disadvantages such as pigment retention or plaque accumulation, which can facilitate caries formation, color variation, ... -
Surface Roughness in Nanoparticle Resin Composites Subjected to Two Polishing Systems: An In vitro Comparative Study
(Journal of International Society of Preventive and Communitary Dentistry, 2022-11-11)Acceso abiertoAim: The surface roughness of dental restorations can decrease resin durability, since it leads to its deterioration, color variation, and loss of gloss. Therefore, the aim was to assess the surface roughness of ... -
The Microhardness and Surface Roughness Assessment of Bulk-Fill Resin Composites Treated with and without the Application of an Oxygen-Inhibited Layer and a Polishing System: An In Vitro Study
(MDPI. Revista Polymers, 2022-07-28)Acceso abiertoThe aim of this study was to assess the microhardness and surface roughness of bulk-fill resin composites treated with and without the application of an oxygen-inhibited layer (OIL) and a polishing system. This in vitro ...
