  1. Classification of failures: (1) adhesive between post and resin cement (no resin cement visible around the post); (2) mixed, with resin cement covering 0–50% of the post surface; (3) mixed, with resin cement covering between 50 and 100% of the post surface; (4) adhesive between resin cement and root dentin (post enveloped by resin cement); and (5) cohesive within the resin cement
