Anteroposterior pelvic radiographs are the gold standard of imaging for mechanical hip problems. However, correct interpretation is difficult because the projected morphologic features of the acetabulum and nearly all routinely used hip parameters depend on individual pelvic position, which can vary considerably during acquisition. We developed software(More)
BACKGROUND Procedures for the treatment of molar furcation invasion defects range from open flap debridement, apically repositioned flap, hemisection, tunneling or extraction, to regenerative therapies. METHODS The results of surgical therapy consisting of the clinical parameters of probing depth and bleeding on probing were compared in 15 patients with(More)
The purpose of this study is to evaluate the potential of decalcified freeze-dried bone allograft (DFDBA) combined with a barrier material in the treatment of human molar furcation defects (experimental) as compared to the barrier technique alone (control). Fifteen pairs of Class II or III furcation invasion defects comprised the study group. Measurements(More)
Homozygous uniparental mouse embryos, produced by microsurgical removal of the male pronucleus from fertilized eggs and diploidization of the female pronucleus with cytochalasin, were surrounded with blastomeres from normal embryos to produce chimeric embryos. A few of these chimeras developed into viable adults, and one female has reproduced using her(More)
Consistently successful regenerative therapy for furcation defects using membrane techniques remains a challenge for clinicians. The purpose of this study was to determine if the thickness of tissue used to cover the membrane influences postsurgery recession. Thirty-seven (37) moderate to advanced adult periodontitis patients presenting with at least one(More)
We developed an object-oriented cross-platform program to perform three-dimensional (3D) analysis of hip joint morphology using two-dimensional (2D) anteroposterior (AP) pelvic radiographs. Landmarks extracted from 2D AP pelvic radiographs and optionally an additional lateral pelvic X-ray were combined with a cone beam projection model to reconstruct 3D hip(More)
Excisional biopsies require wide margins to facilitate removal of diseased tissue. Such margins often result in soft-tissue defects. These defects can cause reduced esthetics, ineffective oral hygiene performance, and postsurgical root sensitivity. This case documents the combination of two dental procedures: biopsy and the free gingival graft. A pyogenic(More)
