“…Although the resin composite evaluated in the present study is indicated for the cementation of ceramic restorations, other light-activated materials (i.e. the so called "veneer cements") have been indicated for the cementation of thin veneers 10 and also have shown good DC results when light-activated through ceramic materials [13][14] . As seen in Table 2, the similar results for DC in most groups indicate that the shade and thickness of the evaluated interposed ceramic veneers did not influence the polymerization of the flowable resin composite.…”

“…In the case of the cementation of ceramic veneers, the use of light-activated resin-based materials has increased due to the working time control 10 . This clinical advantage, however, should not be the determinant factor for material choice in veneer cementation due to the possible attenuating effect provided by thickness, opacity and shades [11][12][13] .…”

The cementation of thin ceramic veneers employing fluid light-activated resin-based materials is a common procedure in the dental practice. Aim: To evaluate the influence of ceramic thickness and shade on the degree of conversion (DC) of a flowable light-activated material. Methods: flowable resin composite (Tetric N-Flow -shade A1) was light-activated through ceramic discs of two shades (IPS Classic -A1 and A3) in three thicknesses (0.5, 0.7 and 1.0 mm). For control, the resin composite was light-activated without ceramic interposition. DC was evaluated by FTIR (n=5). Data were analyzed by one-way ANOVA and Dunnett's T3 test (α=0.05). Results: Statistically significant differences between groups were observed (p<0.001). Control group (without the interposition of ceramic) showed the highest mean for DC (71.9± 1.7). Considering the interposed ceramic disc groups, the highest DC values were obtained when 0.5 and 0.7 mm A1 ceramics were used (64.6±1.2 and 64.4 5.0, respectively) and the lowest DC values were obtained for 0.7 and 1 mm A3 ceramics (61.74±0.9 and 62.0±1.9, respectively). Conclusions: No flowable resin composite group with interposing ceramics reached a DC similar to the control group.

ResumoIntrodução: Cimentos resinosos fotopolimerizáveis são materiais de eleição para a cimentação de facetas laminadas. Devem ser biocompatíveis oferencendo riscos mínimos ao uso clínico em pacientes. Objetivo: O objetivo desse trabalho foi avaliar in vitro a citotoxicidade de três cimentos resinosos: Variolink II (Ivoclar Vivadent), Allcem Veneer, (FGM) e Rely X Veneer (3M ESPE). Material e método: Vinte e quatro corpos de prova de cada cimento foram confeccionados em matrizes metálicas padronizadas e inseridos em placa de cultura de células de noventa e seis poços contendo fibroblastos da linhagem 3T3. As células foram cultivadas em meio de cultivo celular RPMI 1640 com 5% de soro fetal bovino, com 0,1% de penicilina/estreptomicina em estufa a 37°C, em atmosfera úmida com 5% de CO2. O grau de citotoxicidade de cada cimento foi avaliado após os tempos de contato de 24h, 48h e 72h através do método MTT (3-(4,5-dimetiltiazol-2yl)-2,5-difenil brometo de tetrazolina), que avalia a viabilidade celular pela função mitocondrial. Após os tempos estabelecidos, as amostras foram removidas, tratadas e levadas ao espectofotômetro de microplaca para leitura da absorbância em 570nm. Resultado: O cimento Variolink apresentou em 24h viabilidade de 72,24% (±6,80), em 48h de 83,92% (± 5,26) e de 92,77% (±5,59) em 72h. Allcem Veneer apresentou viabilidade de 70,46% (± 12,91) em 24h; 85,03% (± 21,4) em 48h e 70,46% (± 12,91) em 72h. O RelyX Veneer demonstrou viabilidade de 5,06% (± 0,88) em 24h; 5,84% (± 1,18) em 48h e 6,99% (± 1,34) em 72h. Conclusão: Estes resultados demonstraram que o cimento Rely-X se apresentou significativamente mais citotóxico nas condições testadas.Descritores: Facetas dentárias; cimentos de resina; citotoxicidade; resinas compostas; sobrevivência celular. AbstractIntroduction: Light-cured resin cements are the first choice for the cementation of laminate veneers. Ideally, they should be biocompatible and offer minimum risks to patients. Objective: The aim of this study was to evaluate, in vitro, the cytotoxicity of three resin cements: Variolink II, Ivoclar Vivadent (C1), Allcem Veneer, FGM (C2), and Rely X Veneer, 3M ESPE (C3). Material and method: Twenty four samples of each of the cements were fabricated in a standardized metal mold, light activated, and transferred to a 96-well cell plate with culture of fibroblasts. After 24, 48, and 72h of incubation, cytotoxicity was assessed and cell viability was calculated by the methyl-thiazol-tetrazolium (MTT) colorimetric assay. Absorbance was measured at 570 nm using a microplate spectrophotometer. Result: The following results were found: Variolink II presented viability of 72.24% (SD 6.80) after 24h, 83.92% (SD 5.26) after 48h, and 92.77% (SD 5.59) after 72h; Allcem Veneer exhibited viability of 70.46% (SD 12.91) after 24h, 85.03% (SD 21.4) after 48h, and 70.46% (SD 12.91) after 72h; Rely X Veneer showed viability of 5.06% (SD 0.88) after 24h, 5.84% (SD 1.18) after 48h, and 6.99% (SD 1.34) after 72h. Conclusion: Under these testing conditions, Rely X Vene...
