Table 3 Push-out test failure mode distribution for each root third in the resin cement group (n = 20)

From: Bond strength of glass fiber posts cemented with bulk-fill flowable composite resin

  Type 1 Type 2 Type 3 Type 4 Type 5
Cervical 3 (15%) 10 (50%) 3 (15%) 0 (0%) 4 (20%)
Middle 1 (5%) 13 (65%) 1 (5%) 0 (0%) 5 (25%)
Apical 0 (0%) 11 (55%) 0 (0%) 0 (0%) 9 (45%)
  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
