Case ReportsTrismus: or is it tetanus? A report of a case.
Tetanus is a life-threatening infection that is rare in the developed world. Trismus and dysphagia are the most common presenting symptoms, and thus oral and maxillofacial surgeons may be involved in the early stages of evaluation of the patient. Early diagnosis helps initiate prompt management and referral for intensive therapy. This article is a case report of severe generalized tetanus with a discussion of its diagnosis, pathophysiology, and management.

Randomized Controlled Trial Clinical TrialA double-blind comparison of 0.5% bupivacaine with 1:200,000 epinephrine and 0.5% levobupivacaine with 1:200,000 epinephrine for the inferior alveolar nerve block.
This double-blind cross-over study compared the anesthetic success and onset and duration of lip and pulpal anesthesia of 0.5% bupivacaine and levobupivacaine solutions, both with 1:200,000 epinephrine, when administered for inferior alveolar nerve anesthesia. Thirty healthy volunteers were randomly anesthetized using one of the solutions. The inferior canine, second premolar, and molar were tested with electric stimulation. ⋯ At least 250 minutes of pulpal anesthesia was achieved. There were no significant differences between the solutions considering the measured parameters (P > .05). Because of the similar anesthetic behavior of the 2 solutions in this study and the low toxicity related in the literature for levobupivacaine, there is justification for replacing bupivacaine with levobupivacaine for inferior alveolar nerve local anesthesia.

Randomized Controlled TrialComplications after zygoma fracture fixation: is there a difference between biodegradable materials and how do they compare with titanium osteosynthesis?
Biodegradable materials are particularly useful for the fixation of zygomatic fractures. Different systems are commercially available. The aim of this study was to compare the clinical outcome of zygomatic fracture fixation using 3 biodegradable systems and a titanium osteosynthesis system. ⋯ There was no significant difference between biodegradable osteosynthesis materials or between biodegradable materials and titanium fixation with respect to fracture healing and postoperative complications. Postoperative complications were of a minor nature and resolved spontaneously or after local therapy. Smoking habits may play a significant role in the incidence of complications with biodegradable materials.
