The tackiness presented by resins brings inconveniences to the incremental technique, which can be improved by using lubricants in handling. Aim: To evaluate the influence of two adhesive systems as brush lubricants on the degree of conversion, translucency and intrinsic color stability of composite resins. Methods: Samples (n=10) were fabricated according to the composites (Filtek Z350 XT, IPS Empress Direct, and Esthet X HD), shades (bleach shade and A2), and lubricants used (Adper Single Bond 2, Scotchbond Multi-Purpose bonding agent, and no lubricant). Single composite increments were inserted into a Teflon mold. The composite surface was then modeled using a brush dipped in an adhesive system. The control group was fabricated with no additional modeling. The surface degree of conversion (DC) was measured using Fourier transform infrared spectroscopy; translucency and intrinsic color stability were accessed using a spectrophotometer. Data were analyzed using three-way ANOVA and the Tukey test (p<0.05). Results: Scotchbond Multi-Purpose decreased the DC of all composites and shades in comparison with the control group (p<0.05), although it did not decrease color stability (p<0.05). The bleach shade of IPS Empress Direct and Esthet X HD showed higher translucency than the A2 shade when lubricated with the adhesive systems (p<0.05). Conclusion: Therefore, the two tested adhesive systems used as brush lubricants on composites promoted changes to the surface degree of conversion and aesthetic properties.

<p><strong>Objective: </strong>This study analyzed the effect of two light emitting diodes (LEDs) on the degree of conversion (DC) of a composite resin for bleached teeth under the influence of adhesives systems used as modeling liquid. <strong>Material and methods: </strong>A total of 60 samples of IPS Empress Direct resin (Ivoclar, Vivadent) in BL-L shade were made in a single increment and polymerized for 20 seconds. The treatments were: 1) Type of adhesive used as modeling liquid (Adper Single Bond 2; the bond component of Adper Scotchbond Multi-Purpose; or no adhesive systems used as modeling liquid were used in the control group); and 2) Type of LED (Bluephase, polywave; and Coltolux, monowave). The DC, percentage of monomers converted to polymer during polymerization, was were evaluated using Fourier Transform Infrared Spectroscopy (FTIR) with 10 scans and wavenumber related to 1/λ for observation of the peaks at 1608 and 1638 cm^-1. Data were statistically analyzed by two-way analysis of variance (ANOVA) with Tukey's test (<em>p</em>&lt; 0.05). <strong>Results:</strong> There was no statistical difference between LEDs in comparison to the treatments (<em>p</em>&gt; 0.05). However, there was a statistically significant increase in the DC for the adhesive systems tested in comparison to the control group (<em>p</em>&lt; 0.05), with the highest values for Single Bond 2. <strong>Conclusion:</strong> It is concluded that the use of adhesives as modeling liquid of Empress Direct resin for bleached teeth shade increases the degree of conversion of the composite surface, and that curing with both kinds of LEDs does not interfere in this property.</p><p><strong> </strong></p><p><strong>Keywords</strong></p><p><strong></strong>Composite resins; Dentin-bonding agents; Surface properties.</p>

Objective This paper aims to identify, during the educational process, the development of the ability to work in multidisciplinary team, during regular or electives disciplines, in the view of students. Methods This is a descriptive study that used the procedure collects a semi-structured questionnaire directed to graduates of the School of Dentistry, Federal University of Rio Grande do Norte. The data were evaluated based on descriptive statistics. Results The results indicate that interactions with the community in real-world scenarios, in the construction of everyday experiences and significant help in the reflective learning process. Conclusion These practices are found in the Health and Citizenship discipline (SACI RESUMOObjetivo Identificar durante o processo de formação as disciplinas regulares ou optativas que possibilitam o desenvolvimento da habilidade para o trabalho em equipe multiprofissional, na visão dos alunos. MétodosTrata-se de um estudo descritivo, que utilizou como procedimento de coleta um questionário semiestruturado direcionado aos concluintes do Curso de Odontologia de uma Universidade Federal do Rio Grande do Norte. Os dados foram avaliados baseados na análise estatística descritiva. ResultadosOs resultados apontam que as interações com a comunidade em cenários reais, na construção de cotidianos e vivências significativas, auxiliam no processo de aprendizagem reflexiva. ConclusãoEstas práticas são constatadas na Disciplina Saúde e Cidadania, uma atividade realizada desde o ano 2000/ 2º semestre e integra ações de ensino, pesquisa e extensão, com bases fundamentadas no diálogo entre os saberes sistematizado e tradicional, igualmente importantes na relação entre educação, saúde e cidadania.Termos de indexação: Educação em Odontologia.
