The international normalized ratio, or INR, was introduced in 1983 by the World Health Organization, or WHO, Committee on Biological Standards to more accurately assess patients receiving anticoagulation therapy. The INR mandates the universal standardization of prothrombin time. This article describes the method used to calculate INR, as well as its clinical relevance to the practice of dentistry.

This report details a pilot study of the maxillomandibular fixation screw. A longer study with a greater number of patients will allow for better evaluation of this technique.

The classification, pathophysiology, and treatment of angioedema is reviewed. An overview of acquired and hereditary angioedema is presented with an interesting case report that illustrates the importance of recognition and perioperative management of hereditary angioedema to prevent a potentially fatal outcome.

Accuracy of cephalometric tracings and model surgeries is of utmost importance in planning for orthognathic surgery. The technique described allows surgeons to verify position of the models by superimposing a cephalogram of the mounted models over that of the patient. It also reduces the chance of error during actual surgery by placing models in centric relation. Therefore, the possibility of intraoperative complications, and thus longer operating times, is minimized.
