OBJECTIVES: The aim of the study was to test whether or not the shear bond strengths of six self-adhesive resin cements to dentin and to glass-ceramic, 24h and long-term-aged, are similar to the one of a conventional resin cement. METHODS: Human molars (N=168, n=12 per group) and silicabased glass-ceramic specimens (N=168, n=12 per group) were embedded in acrylic resin and randomly divided into 28 groups. The following resin cements were luted according to the manufacturers' instructions: Clearfil SA (CSA), G-Cem (GCM), SmartCem2 (SMC), SpeedCEM (SPC), RelyX Unicem (RXU), RelyX Unicem2 (RXU2) and Panavia21 (control group, PAN). Shear bond strength was measured initially (24h of water storage 37°C) and after aging (24,000 thermal cycles, 5/55°C). The failure types (adhesive, and cohesive) were evaluated after debonding. The shear bond strength values were analyzed using three-way and one-way ANOVA, followed by a post hoc Scheffé and two-sample Student's t-tests. RESULTS: RXU, RXU2 and GCM showed similar after 24h and aged shear bond strength to dentin as the control group. CSA, SMC and SPC exhibited significantly lower values. Before aging, none of the bond strength values to glass-ceramic differed significantly from the other. After thermocycling, GCM showed higher results to glass-ceramic than CSA, SMC, RXU2 and the control group. Analyzing failure types after spontaneous debonding and shear bond test at dentin, solely adhesive failures were found, while at glass-ceramic only cohesive failures occurred. CONCLUSION: Not all self-adhesive resin cements can be a valid alternative to conventional resin cements in order to bond silica-based glass-ceramics to human dentin.

There are many ways dentists can restore teeth prosthetically. Depending on its condition of relative integrity or more serious breakdown and the patient's loss of other teeth, the practitioner can choose from a variety of quite different procedures ranging from the fabrication of a single ceramo-ceramic crown on a vital tooth to correction of considerable loss of teeth with an implant supported bridge. This paper will evaluate most of these treatment modalities and, in addition to purely prosthetic considerations, will discuss the integration into treatment of periodontal, implant, occlusal, and functional concepts.

“…Mas, além disso, os compostos resinosos possuem outros atrativos que justificam a sua utilização em grande escala, desde uma resistência considerável, custo acessível, adesividade e a possibilidade de preparos cavitários mais conservadores 5 . Entretanto, elas também possuem algumas limitações que não superam as suas vantagens, tais como as relacionadas às suas propriedades mecânicas, contração de polimerização, toxicidade e instabilidade ou alteração de cor 6 .…”

ResumoO surgimento das resinas compostas, da técnica de condicionamento ácido e dos variados tipos de adesivos provocaram uma revolução na Odontologia, que aperfeiçoou a devolução da função e estética ao dente. Um dos grandes desafios atuais em dentística restauradora é a manutenção da estética das restaurações de resina composta. O objetivo deste estudo foi revisar a literatura sobre a alteração de cor nas resinas compostas, evidenciando o estado atual das pesquisas sobre o tema. Foi realizada uma síntese de estudos in vitro realizado no período de janeiro de 2011 a janeiro de 2016 indexados na base de dados Pubmed. Seguindo os critérios de inclusão, entraram nesta revisão 13 estudos que avaliaram o grau de descoloração de resinas compostas frente à exposição a diferentes líquidos de coloração. Concluiu-se que apesar do rápido desenvolvimento da biotecnologia e nanotecnologia na Odontologia, novas pesquisas precisam ser feitas a fim de encontrar um material restaurador com propriedades mecânicas e estéticas de excelência, superando as limitações dos atuais.

AbstractThe emergence of composite resins, acid etching technique and various types of adhesives caused a revolution in dentistry, who perfected the return of function and aesthetics of the dental organ. One of the main challenges in restorative dentistry is to maintain the aesthetics of composite restorations. The aim of this study was to review the literature on color changes in the composites, showing the current state of research on the subject. In vitro synthesis studies conducted from January 2011 to January 2016 indexed in Pubmed database was performed. Following the inclusion criteria entered in this review 13 studies that assessed the degree of discoloration composite front resins to exposure to different staining liquids. It was concluded that despite the rapid development of biotechnology and nanotechnology in dentistry, further research needs to be done in order to find a restorative material with mechanical and aesthetic properties of excellence, overcoming the limitations of current.
