Ceramic materials in dentistry: historical evolution and current practice

Dental ceramics are presented within a simplifying framework allowing for facile understanding of their development, composition and indications. Engineering assessments of clinical function are dealt with and literature is reviewed on the clinical behaviour of all-ceramic systems. Practical aspects are presented regarding the choice and use of dental ceramics to maximize aesthetics and durability, emphasizing what we know and how we know it.

Acrylic resin cytotoxicity for denture base - Literature review

Acrylic resin is a widely used material in clinical practice, and a satisfactory biocompatibility is essential. When the resin polymerization reaction is incomplete, residual monomers are released into the oral cavity. The aim of this study was to evaluate, through a literature review, the cytotoxicity caused by the denture base acrylic resin used, and its components. The selection of published studies was performed on the Pubmed database from January 2008 to July 2013. The keywords used were: cytotoxicity and acrylic resins, cytotoxicity and denture base resins and cytotoxicity and oral prosthesis. Inclusion criteria were: in vitro studies and literature reviews published in English that evaluated the acrylic resin cytotoxicity for denture base and its components. Studies with no reference to the search strategy were excluded. A total of 182 articles were found. Among these, only 13 were included for writing this review. The MTT test is the most common test used to evaluate acrylic resin cytotoxicity. Auto-polymerized resin is more cytotoxic than heat-polymerized resin because of its higher quantity of residual monomers which cause cell and tissue changes in the oral mucosa. However, more studies are necessary for the development of biocompatible materials.

As representações do feminino em As brumas de Avalon, de Marion Zimmer Bradley

This present work is a theoretical and qualitative research divided into three chapters that aims to demonstrate how the representations of the female in the book The Mists of Avalon (1982), writing by Marion Zimmer Bradley, dialogues and revises the tradition of cavalry novels on the Arthurian legend, particularly Thomas Malory's Le Morte D'Arthur (1485) which brings the female from the images ideologically constructed of angel and monster. Bradley innovate the Matter of Britain when she created a version of the Arthurian myth following a perspective guided on the female. From the analysis of the history of Bradley's writing as well as the historical context of the development of feminism and the feminist criticism in which she wrote will be sought-point as The Mists of Avalon part of the tradition, but reframes the traditional episodes in order to deconstruct the patriarchal sense and the male images about the feminine
