Estabilidade de cor é um requisito estético fundamental das resinas acrílicas provisórias, em especial quando esses materiais são submetidos a longos períodos na cavidade oral. Embora resinas acrílicas temporárias novas e aprimoradas estejam disponíveis, os efeitos da variação térmica e de so...
Abstract The purpose of this study was to evaluate the color adaptation of single-shade resin composites applied to different tooth shades. A total of 108 class III preparations (n=6) were performed on the acrylic denture maxillary incisors (2mm depth and 2mm height). 5 single-shade resin composites (Vit...
A fim de conter o avanço das lesões incipientes de cárie (LMB: lesões de mancha branca) e, oportunamente, de minimizar seu aspecto estético insatisfatório, a infiltração com material resinoso fotopolimerizável de baixa viscosidade e alto coeficiente de penetração vem sendo indicada. Contudo, n...
Aim: The aim of this study was to verify the color variation between different composite resins and the Vita Classical Shade Guide. Methods: Two-millimeter thickness samples were made (n = 6) from eight commercial brands of composite resin (shade A2): Charisma (Kulzer), Forma (Ultradent), Harmonize (Kerr...
Aim: To evaluate the surface roughness and color stability of bulk-fill resin composites after simulated toothbrushing with whitening dentifrices. The radioactive/relative dentin abrasion (RDA) and radioactive/relative enamel abrasion (REA) of dentifrices were also assessed. Methods: Specimens (n=10) of ...
O estudo avaliou o efeito da adição de partículas bioativas ao gel clareador (peróxido de hidrogênio 35%, técnica de consultório), quanto ao clareamento e sobre a estrutura dental, além da resistência à desmineralização. O objetivo da primeira parte do estudo foi avaliar géis, com diferentes...
Objective: To evaluate the effects of different commercially available charcoal-based toothpastes (CBTs) on the roughness and color of bulk-fill resin composites (RCs). Materials and Methods: Disc-shaped samples (6 × 2 mm) were made with nanofilled (NF) bulk-fill (Filtek One, 3M Oral Care) or nanoh...
Objective: This study assessed the properties of four resin-based composites (Charisma Classic, Charisma Diamond, Filtek Z350XT, and Filtek Bulk Fill) concerning water sorption and color stability under different radiant exposures of a broadband LED device (Valo Cordless, Ultradent) and immersion solutio...
Aim: To evaluate the bleaching efficacy, decomposition rate, and pH of experimental gels containing 35% hydrogen peroxide (HP) and different concentrations of 45S5-bioglass (BG) or Biosilicate® (BS). Methods: Bovine enamel/dentin blocks (n=10) were allocated into the groups HP_BG or HP_BS (2.5, 5, 7.5 a...
