Journal ArticleDOI
A multipurpose natural and renewable polymer in medical applications: Bacterial cellulose
Hélida Gomes de Oliveira Barud,Robson Rosa da Silva,Hernane da Silva Barud,Agnieszka Tercjak,Junkal Gutierrez,Wilton R. Lustri,OB Oliveira,Sidney José Lima Ribeiro +7 more
TL;DR: The aim of this review is to discuss about the applicability in biomedicine by demonstrating a variety of forms of this biopolymer highlighting in detail some qualities of bacterial cellulose.
Journal ArticleDOI
Direct esthetic restorations based on translucency and opacity of composite resins.
TL;DR: The objective of this article is to provide a review of the phenomena of translucency and opacity in the natural dentition and composite resins, under the scope of optics, and to describe how to implement these concepts in the clinical setting.
Journal ArticleDOI
The perception of smile attractiveness.
TL;DR: The absence of variations from beauty norms of a smile has a positive impact on its esthetic perception, but variations from the norms do not necessarily result in reduced attractiveness.
Journal ArticleDOI
Effectiveness of 6% hydrogen peroxide concentration for tooth bleaching—A double-blind, randomized clinical trial.
Javier Martín,Javier Martín,Patricio Vildósola,Patricio Vildósola,Cristian Bersezio,Cristian Bersezio,Andrea Herrera,Janaína Freitas Bortolatto,José Roberto Cury Saad,OB Oliveira,Eduardo Fernández,Eduardo Fernández +11 more
TL;DR: A 6% hydrogen peroxide with nitrogen-doped titanium dioxide light activated agent is effective for tooth bleaching, reaching a ΔE of 5.57 one month after completing the treatment, with no clinical differences to a 35% agent neither in colour change or in tooth sensitivity.
Journal ArticleDOI
Effects of Light Activation, Agent Concentration, and Tooth Thickness on Dental Sensitivity After Bleaching
Gustavo Moncada,D Sepúlveda,K Elphick,Marta Maria Martins Giamatei Contente,Juan Estay,Valeria Bahamondes,Eduardo Fernández,OB Oliveira,Javier Martín +8 more
TL;DR: Increases in the concentration of bleaching agents directly affect tooth sensitivity, and LED/laser activation and tooth thickness are not correlated with tooth sensitivity after dental bleaching.
