Resumo: | Introduction: A new laboratorial resin generation that content ceramic microparticles in its composition has been introduced in the market with the purpose to improve its mechanical properties. Objective: The objective of this study was to evaluate the effect of the thermocycling in the flexural strength of three laboratorial resins. Method: Forty-eight specimens with measures of 2 mm × 2 mm × 25 mm were made using laboratorial resins: G1 - RESILAB MASTER (Wilcos, Brazil), G2 - VITA VM LC (Vita Zanhfabrik, Germany) and G3 - VITA ZETA (Vita Zanhfabrik, Germany). After their confection, half of each group was submitted to 3000 thermal-cycles (5ºC/55ºC ± 1, with rinse bath of 30 s). The mechanical essays were done in Universal essay machine EMIC with the loading capacity of 100 kg and the equispeed of 0,5 mm/min. Results: The obtained data was analyzed statistically by the ANOVA test (two-way) and Turkey’s test (p < 0,05). The averages (± DP) observed for the groups without cycles were: G1(112,6 ± 25,39), G2(116,5 ± 18,51) and G3(136,1 ± 24,34); and for the groups with cycles: G1(91,8 ± 18,86), G2(101,9 ± 20,61) and G3 89,9 ± 23,05). Conclusion: It was concluded that the decrease in the flexural strength in MPa is directly dependent on the thermo-cycling in the tested groups, being that the highest values were obtained by VM LC resin. However, in the group without thermo-cycling the VITA ZETA showed the highest values. UNITERMS: three point bending; thermo-cycling; composite resin. |

Objetivo: O objetivo deste estudo foi avaliar o efeito da termociclagem na resistência à flexão de três resinas laboratoriais. Materiais e método: Foram confeccionadas 48 barras com medidas de 2 mm × 2 mm × 25 mm, utilizando as resinas laboratoriais: G1 - RESILAB MASTER (Wilcos, Brasil), G2 - VITA VM LC (Vita Zanhfabrik, Germany), G3 - VITA ZETA LC (Vita Zanhfabrik, Germany). A metade das barras de cada grupo foi submetida a 3000 ciclos térmicos (5ºC/55ºC ± 1, com banhos de 30 s). Os ensaios mecânicos foram efetuados em máquina de ensaio universal EMIC com capacidade de carga de 100 kg e velocidade de 0,5 mm/min. Resultados: Os dados obtidos foram analisados estatisticamente pelo teste de ANOVA (two-way) e Tukey (p < 0,05). As médias (± DP) observadas para os grupos sem ciclagem foram: G1(112,6 ± 25,39), G2(116,5 ± 18,51) e G3(136,1 ± 24,34); e para os grupos com ciclagem: G1(91,8 ± 18,86), G2(101,9 ± 20,61) e G3(89,9 ± 23,05). Conclusão: Concluiu-se que a diminuição da resistência à flexão em MPa está diretamente dependente da ciclagem térmica nos grupos testados, sendo que os maiores valores foram obtidos pela resina VITA VM LC. Entretanto, na condição sem ciclagem térmica a VITA ZETA apresentou os maiores valores.
