| Resumen en español | Por los resultados obtenidos puede concluirse de que las resinas fotopolimerizadas por luz halógena presentaron los mejores resultados de resistencia a compresión con excepción de la resina compuesta Tetric Ceram |
| Resumen en inglés | This study main purpose was to evaluate the mechanical response of three different resin composite brands; Filtek Supreme, Charisma and Tetric Ceram cured by halogen or light emitting diode – LED (Optilght,Gnathus e Ultraled, Dabi Atlante). A nylon mold 4-mm in diameter and 8-mm in depth was used to obtain forty eight specimens dived in 6 groups of 8 varying the light-curing unit; G1 Filtek Supreme, G3 Tetric, G5 Charisma cured by halogen light-curing unit, and G2 Filtek Supreme, G4 Tetric, G6 Charisma cured by LED. The resin composites were inserted according to the incremental method. The resin composites were light cured according to the manufactures’ instructions. The specimens were kept in plastic containers airtightly closed for 24 hours. In order to perform the evaluation, an EMIC DL 2000 was used at a crosshead speed of 0.5 mm/minute and a charge cell of 2000 Kg strength. The statistical analysis was performed using one-way analysis of variance (ANOVA) and Tukey test at a p<0.05 significance level. The mean were G1 248.37, G2 193.75, G3 222.00, G4 195.87, G5 280.37, G6 205.25. In conclusion, the resin composites light-cured by halogen scored higher in the compressive strength test. In the Tetric Ceram group there were no statistically relevant results |
