Item A Cephalometric Appraisal of Dentofacial Changes Following the Insertion of Artificial Dentures(1955) Starr, Richard; Muhler, Joseph; Phillips, RalphItem Attachment of Anterior Tooth Fragments(1985) Dean, Jeffrey A.; Swartz, Marjorie L.; Avery, David; Barton, Paul; Klein, Arthur; Phillips, RalphThis investigation examined the relationships of preparation and resin material types in the reattachment of fractured anterior tooth fragments. 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).Item The Integumental Profile: A Study of Acceptable Adolescent Faces(1957-07) Lehman, David G.; Adams, J. William; Mulher, Joseph; Van Huysen, Grant; McDonald, Ralph; Shafer, William; Phillips, Ralph
