Observed in this study were morphologic changes in inflamed nerves, along with biochemical changes, which appear to act concurrently to deactivate or prevent activation of the local anesthetic solution. Morphologic changes were observed along the nerve fiber distant from the inflammatory site. These neuro-degenerative changes were seen at the axon and myelin sheaths level. The biochemical data support the presence in the inflamed nerve of amino acids which may be the product of lysosomal rupture and proteolytic enzyme release. These inflammatory mediators may affect either the local anesthetic or the environment of the nerve fiber. The precise mechanism of action of these catalytic products cannot be determined from this study.

The purpose of the present investigation was to evaluate the biocompatibility of vitreous carbon, pyrolytic carbon, and pyrolytic graphite/silicon-carbide with rabbit mandibular tissues. Titanium was employed as the control material. Twelve New Zealand albino rabbits were implanted with each of the four materials described. Groups of four animals each were killed at 14 days, 45 days, and 90 days. Block sections containing the implants were then removed from the rabbit mandibles, and representative sections were evaluated histologically. All of the implants elicited similar reactions, including fibrous connective tissue capsule formation, multinucleated phagocytic cells, a mild inflammatory infiltrate, and reactive bone. On the basis of these findings, it appears that further detailed investigations are necessary to elucidate the biologic ramifications of the implantation of carbons in mammalian tissues.

A review of the literature indicates that an allergic response to stainless steel is rare, although nickel is a common allergen and is encountered continually in daily life. An allergic reaction could occur at a most inopportune time. Rational approaches in management of an allergic response to stainless steel appear to be either: (1) wire removal and symptomatic therapy, (2) application of fixation with other substances, or (3) administration of steroids with necessary stainless steel immobilization left in place. The report suggests the need for research to determine the chromium content or chromium-nickel ratio that would eliminate allergic manifestations to the nickel component in wrought or cast base metal dental appliances.

1. A retrospective cephalometric study of patients who underwent reduction genioplasties showed large variations in soft-tissue response to osseous reduction. 2. The vertical and horizontal soft-tissue changes coincident to osseous reduction were less than expected. The maximum soft-tissue change observed was approximately 50 per cent that of the hard tissue removed. On the average, the vertical soft-tissue change was about 30 per cent and the horizontal was 25 per cent, when degloving procedures were combined with some form of ostectomy. 3. A considerable length of time is necessary before the soft-tissue changes are stable after reduction genioplasty. In some cases, significant changes occurred up to 8 to 10 months postoperatively. 4. A classification of macrogenia is proposed, based upon a more exact anatomic description of the deformity. 5. On the basis of this classification, the results of the present study, and more recent clinical results, recommendations for the surgical treatment of macrogenia are made.

Basal-cell carcinoma most commonly occurs in men in the fifth to seventh decades of life. The area of the lesion is usually one that has frequent exposure to the sun: the middle third of the face and upper lip. An unusual case of basal-cell carcinoma occurring on the lower lip and involving the commissure in a 21-year-old woman is presented. The surgical procedures for resection of the tumor and reconstruction of the commissure are described.

A lateral compression clamp system has been used in the treatment of fractures of the mandible. It provides rigid fixation and promotes earlier osteogenesis at the fracture site. Intermaxillary fixation can often be eliminated in edentulous persons and greatly reduced in duration when necessary as an adjunct to fixation in patients with teeth. These significant qualities make the compression clamp quite beneficial in the treatment plan and postoperative management of many otherwise difficult cases. Having evaluated our experiences with compression clamps, we believe that this approach deserves further attention and may contribute to a solution of the controversy that often exists regarding the management of mandibular fractures in both edentulous patients and those with a compromised complement of teeth.

Successful clinical applications since early 1970 have occurred with the use of temporomandibular condylar prosthesis and endosseous blade-vent implants coated with porous proplast. Proplast as a bulk material has also been used to augment atropic mandibular alveolar ridges and deficient facial contours in the mental, mandibular border, and zygomatic areas.
