dc.description.abstractObjetivo: Comparar in vitro la microdureza superficial de dos resinas convencionales con dos resinas Bulk Fill precalentadas. Materiales y Métodos: La muestra estuvo conformada por 112 discos de resina compuesta. Se utilizaron 2 marcas de resinas convencionales (Te-Econom Plus® y Filtek™Z350XT) y Bulk Fill (Tetric® N- Ceram Bulk Fill y Filtek™ Bulk Fill). Se formaron 2 grupos (control y precalentadas) por cada marca de resina compuesta. El grupo control se realizó de acuerdo con las indicaciones del fabricante y el grupo precalentadas se expuso a 40°C a través de la máquina AR HEAT/15 min. Se evaluó la microdureza superficial a través de un Microdurómetro Electrónico punta Vickers (carga: 0.4903 N/10 s.). Los datos fueron analizados mediante estadística descriptiva (media ± desviación estándar) y la comparación de variables, se realizó mediante las pruebas de t de Student, Wilcoxon y U de Mann Whitney. Resultados: Los valores de microdureza superficial (media±d.e.) fueron: 15.33±3.10 en la resina Te-Econom Plus®, 18.80±0.80 en la resina Tetric® N- Ceram Bulk Fill, 38.12±1.49 en la resina Filtek™Z350XT y 28.80±0.80 en la resina Filtek™ Bulk Fill. Se encontraron diferencias significativas entre las resinas Bulk Fill y sus correspondientes resinas convencionales (p<0.0001y p=0.0002). Conclusión: Al comparar in vitro la microdureza superficial de dos resinas convencionales y dos resinas Bulk Fill precalentadas a 40ºC, se demostró que las resinas tipo convencional 3M ESPE® y Bulk Fill Ivoclar Vivandent® presentaron mayor microdureza superficial. Asimismo, el precalentamiento a 40ºC aumentó la microdureza superficial de las resinas evaluadas a excepción de las resinas Filtek™ Bulk Fill. Esta técnica favorece a la dureza del material restaurador según la composición de cada resina.en_US
dc.description.abstractAim:  To compare in vitro the superficial microhardness of two conventional composite resins with two preheated Bulk Fill composite resins.   Materials and Methods: The sample consisted of 112 composite resin discs. Two brands of conventional composite resins (Te-Econom Plus® and Filtek™Z350XT) and Bulk Fill composite resins (Tetric® N- Ceram Bulk Fill and Filtek™ Bulk Fill) were used. Two groups (control and preheated) were made for each composite resin brand. The control group was carried out in accordance with the manufacturer’s instructions and the preheated group was exposed to 40°C heat using an AR HEAT/15min machine. The superficial microhardness was evaluated using a microhardness tester and a Vickers diamond indenter (Electronic Microdurometer - load: 0.4903 N/10 s.). The data was analyzed using descriptive statistics (mean, ±standard deviation) and the variables comparison was performed using Mann Whitney's Student, Wilcoxon, and U t-tests.   Results: The superficial microhardness values (mean ±sd.) were: 15.33±3.10 for Te-Econom Plus® and 8.80±0.80 for Tetric® N- Ceram Bulk Fill; (p<001). For Filtek™Z350XT the value was 38.12±1.49 and for Filtek™ Bulk Fill; (p<0.01) it was 28.80±0.80. The microhardness of all resins increased after preheating when compared with the control group, except for the Filtek Bulk resin.   Conclusion: Comparing in vitro the superficial microhardness of two conventional resins and two Bulk Fill type resins preheated to 40ºC, it was observed that conventional 3M ESPE® resin and Bulk Fill Ivoclar Vivandent® resin presented higher superficial microhardness. It was concluded that preheating to 40ºC increases the superficial microhardness of the composite resins evaluated, except for the Filtek™ Bulk Fill. This procedure improves the hardness of the restorative material in accordance with the composition of each composite resin.en_US
