Failure mode of the dislodged specimens from three experimental groups. Data are expressed as percentages (%) of the total number of specimens tested for each group. Cohesive failures within the fiber post or failures within luting agent were not observed in any of the groups and were therefore not presented on the graph. Abbreviations: AD-adhesive failure between dentin and luting agent; AP-adhesive failure between luting agent and fiber post; M-mixed
