  1. The failure modes of glass fiber post cemented with bulk-fill flowable resin and resin cement were classified into 5 different types: (1) adhesive failure between the post and resin cement; (2) adhesive failure between the resin cement and root dentin; (3) cohesive failure within the fiber post; (4) cohesive failure within the dentin; and (5) mixed failure with the resin cement partially covering the post surface
