Abstract
The aim of this study was to investigate the influence of cementation technique on the retention of resin bonded fiber posts. The cementation techniques were one step (one layer) cementation technique (conventional technique) and two step (two layers) cementation technique (by the help of the teflon post). The cements used were: Self - adhesive: RelyX - Unicem, self - etch: Multicore flow. A total of thirty fiber posts were used in this study, thirty upper central incisors of comparable size and length were selected. The teeth were kept in normal saline until used. The natural crowns were sectioned perpendicular to the long axis 2mm coronal to cemento-enamel junction. Using standardized technique the root canals were be then endodontically treated using conventional technique. Standardized post space were prepared to receive the selected fiber posts. The posts were assigned to two equal groups (n = 15) according to the technique of cementation used (one step cementation technique or two step cementation technique). The cements used were: Self - adhesive: RelyX - unicem, self - etch: Multicore flow. total etch: Rely X Ultimate
