Resumen

Las restauraciones adhesivas indirectas son cada vez más parte de los procedimientos de rehabilitación oral. Con el propósito de reducir y minimizar las dificultades y simplificar la técnica de cementación con cementos de resina adhesivos convencionales, se introdujo un cemento de resina denominado autoadhesivo porque presenta adhesión química a los tejidos dentales, superficies cerámicas y metálicas sin necesidad de grabado ácido y el uso de sistemas especiales pegatinas. Algunos estudios apuntan al problema de la degradación del cemento durante el almacenamiento. Los inhibidores y peróxidos presentes en la composición del cemento son componentes químicos orgánicos y, por tanto, son susceptibles de sufrir fenómenos de degradación durante el almacenamiento. Debido a todos estos factores, los cementos de resina tienen una vida útil limitada y pueden ocurrir cambios en el mecanismo de polimerización durante este período. El presente estudio fue elaborado conteniendo algunas variables objeto de investigación. Todas estas variables buscaron investigar las consecuencias de los diferentes protocolos de activación de la polimerización y el envejecimiento acelerado de los cementos resinosos autoadhesivos de polimerización dual sobre su grado de conversión, así como probar la hipótesis nula de que el protocolo de activación de la polimerización y el envejecimiento acelerado no causaron cambios en la conversión. el grado de conversión de los materiales a ensayar.
