The Biological Effects of 3D Resins Used in Orthodontics: A Systematic Review

Three-dimensional (3D) resin medical-dental devices have been increasingly used in recent years after the emergence of digital technologies. In Orthodontics, therapies with aligners have gained popularity, mainly due to the aggressive promotion policies developed by the industry. However, their systemic effects are largely unknown, with few studies evaluating the systemic toxicity of these materials. The releas...

What Is the Most Effective Technique for Bonding Brackets on Ceramic-A Systemat...

Background: There has been an increase in demand for orthodontic treatment within the adult population, who likely receive restorative treatments using ceramic structures. The current state of the art regarding the most effective method to achieve an appropriate bond strength of brackets on ceramic surfaces isn't consensual. This systematic review aims to compare the available surface treatments to ceramics and...

It consists of a stainless-steel ...

Recoloring Algorithms for Colorblind People: A Survey

Color is a powerful communication component, not only as part of the message meaning but also as a way of discriminating contents therein. However, 5% of the world’s population suffers from color vision deficiency (CVD), commonly known as colorblindness. This handicap adulterates the way the color is perceived, compromising the reading and understanding of the message contents. This issue becomes even more pert...

Contour Enhancement Algorithm for Improving Visual Perception of Deutan and Pro...

A variety of recoloring methods has been proposed in the literature to remedy the problem of confusing red-green colors faced by dichromat people (as well by other color-blinded people). The common strategy to mitigate this problem is to remap colors to other colors. But, it is clear this does not guarantee neither the necessary contrast to distinguish the elements of an image, nor the naturalness of colors lea...

Adaptação da cor da tipografia páginas web para pessoas com deficit na visão da...

A legibilidade do texto é fundamental à sua leitura, sendo para isso determinante o contraste entre as cores usadas para a tipografia e para o fundo. Ainda que a escolha das cores seja adequada, o contraste pode ser insuficiente quando a tipografia é observada por pessoas com deficit na visão da cor, comprometendo assim a legibilidade. Sendo que é significativa a taxa de incidência do deficit na visão da cor, c...

Atualmente, as linguagens de programação são usadas por pessoas com formação em domínios cada vez mais diversos e distintos do habitual, tendo já chegado ao domínio das artes. A linguagem Processing, que tem um cariz visual e que possibilita o desenvolvimento de aplicações/performances com elementos visuais e sonoros, foi mesmo projetada para ser usada por artistas. Contudo, a preparação prévia e a sensibilidad...

A recoloring algorithm for dichromates

The color is a valuable communication resource, not just as part of the message itself, but also as a way of discriminating between the diverse contents of a given message. However, not all people have the ability to distinguish the color in a normal way. About 5% of the world population (8% of men) has a visual impairment, called color vision deficiency (CVD) or, simply, colorblindness. This vision deficiency ...
