The trigeminal nerve is the great sensory nerve of the facial portion of the head, and an intimate knowledge of this nerve and its surrounding structures is a prerequisite to the application of profound local anesthesia without complication. In this review article, the classic description of the relevant anatomy is described and is updated with recently published research into anatomic variations that have an impact on the induction of clinical local anesthesia. Causes of both failure and complications of traditional local anesthetic techniques are explained, and recommendations for avoiding these pitfalls are made.

Randomized Controlled Trial Comparative Study Clinical Trial
The use of sterile versus nonsterile gloves during out-patient exodontia.
One hundred twenty-four patients who showed no clinical evidence of acute infection, were not taking antibiotics, and were to undergo routine removal of erupted teeth were studied. Patients were alternately assigned to surgeons who were wearing sterile or nonsterile, but clean, gloves. ⋯ None of the patients was found to be infected postoperatively. Results of this prospective study suggest that routine exodontia can be safely performed by a surgeon wearing nonsterile, but surgically clean, gloves without increasing the risk of postoperative infection.

Fourteen patients suffering from primary muscular disease (myopathies), including seven with Duchenne's muscular dystrophy, were compared to 11 patients whose neuromuscular disorders were of neuropathic origin. Mesioclusion was observed only in the group with Duchenne's muscular dystrophy. ⋯ The Duchenne's patients exhibited a statistically significant delay in dental emergence, unlike the patients with other myopathies and those with neurogenic disorders. Dentition and occlusion may be more affected in patients with myopathies, especially Duchenne's muscular dystrophy, than they are in patients with neurogenic disorders.
