A total of 44 extracted maxillary central incisors were tested. Statistical analysis revealed that no-handpiece preparation was as retentive as a 45° circumferential bevel (p <.01). In addition, the light-cured resin proved as retentive as did the chemically-cured resin (p<.01). Also examined was the effect of the initial fracture angle on retention of the fragment after reluting. Teeth fractured with an angle sloping cervically in a lingual-to-facial direction when viewed proximally were more retentive than other types of fractures when subjected to a lingually directed force from the labial (p L.OS).Tooth FracturesThesis
