The purpose of this study was to investigate long-term clinical effectiveness of treating painful cracked teeth with a direct bonded composite resin restoration.


N= 41 inclusion criteria: painful response to chloraethyl, tooth slooth, visible fracture line in distal after removal of restoration.—All had amalgam. 20 teeth restored with composite without cuspal coverage 21 with cuspal coverage. Randomly distributed.Recall after 7 y =40 (97%)


1.Three teeth without cuspal coverage needed an endodontic treatment, of which 2 failed as a result of fracture. No significant differences were found for tooth or pulp survival.

2.Mean annual failure rate of restorations without cuspal coverage was 6%; no failures in restorations with cuspal coverage occurred

Clinical Significance:

A direct bonded composite resin restoration can be considered in the treatment of a cracked tooth, when considering all the literature for vitality protection.
