N1 - dc.publisher: FDI World Dental Press This in vitro research demonstrated that a simple clinical technique is satisfactory to retain a post system and that suitable and predictable bonding can be obtained using a resin-modified glass ionomer.

N2 - This study examines retention of a quartz-fibre endodontic post cemented in extracted human teeth using two cement types. Fifty-four extracted buman central incisor teeth were prepared for a tapered quartz-fibre post. Posts were cemented in 28 teeth using conventional resin cement (RelyX ARC), and 26 teeth using self-adhesive resin cement (RelyX Unicem). Posts were cyclically-loaded. Bond strengths were tested and dependability assessment was carried out. Although there was no significant difference in Weibull modulus between groups (p < 0.05), greater dependability was displayed by RelyX Unicem group. Easy application and greater dependability of self-adhesive cement may improve bonding of fibre-based posts in root canals.
