Uno de los principales factores relacionados con el sellado de perforaciones en furca es la deficiente retención de los materiales sellantes, actualmente un cemento a base de mineral trióxido agregado (MTA) se ha utilizado para este fin. El propósito de este estudio es el comparar la capacidad de retención del cemento MTA en perforaciones en furca con y sin presencia de humedad. Se utilizaron 30 molares extraídos humanos, los cuales fueron divididos en dos grupos, se les realizó una perforación en furca que fue sellada con cemento MTA. Después de 72 horas de fraguado a 37°C con presencia de humedad y sin presencia de humedad se les realizaron pruebas de desalojo con una máquina universal de prueba Instron. Los resultados obtenidos muestran que no existe diferencia significativa al fraguar el cemento MTA con presencia de humedad y sin presencia de humedad a las 72 horas (p = 0.112).
Palabras clave: Desalojo; furca; cemento MTA
One of the main factors related with the sealing of perforations in furcation is the deficient retention of the sealing materials. Nowadays a mineral trioxide aggregate (MTA) base cement is used for this purpose. The intention of this study was to compare the capacity of retention of MTA cement in perforations in furcation with and without humidity presence. Thirty human extracted molars were used, and divided into two groups. A perforation in furcation was done to them and was sealed with MTA cement. After 72 hours of setting at 37°C, with and without humidity, push out tests were done with Instron. The results show there was no significant difference when the MTA cement sets, with or without humidity presence within 72 hours (p = 0.112).
Key words: MTA cement; furcation; push out
