Case reports have described displacement and migration of teeth in the upper and lower dental arches, but migration of a tooth across the mandibular midline is rare. The authors describe an extremely rare case of bilateral transmigration of impacted permanent canines across the midline of the mandible.
All-terrain vehicles (ATV) are designed for off-the-road occupational or recreational use. As their popularity has been increasing steadily, information has been accumulating on the morbidity and mortality associated with their use. The attributes of the ATV that make it attractive for recreation and sport are the reasons for much of its danger. Thus, horsepower, speed and ability to travel on rough and uncertain terrain are causal factors for accidents. The poor judgment and risk-taking of many of the young and immature drivers contribute to the great danger. 61 admissions due to ATV accidents from October 1992 to April 1995 are reviewed. The data suggest that ATV riders are at high risk for serious skeletal injuries and death. ATVs clearly present health hazards for riders of all ages, unless they are driven with great care. Guidelines for reducing the number and severity of injuries, such as age limits, safety programs and protective equipment are suggested.
PURPOSE: To describe the use of endoscopy as a technique for diagnosing and treating sialolithiasis. Sialolithiasis is a common pathology of the major salivary glands, yet its accurate detection and treatment is still intriguing. PATIENTS AND METHODS: Eight cases of sialolithiasis were treated with our new technique which combines endoscopy and treatment. Two illustrative patients treated by this technique are described in detail. CONCLUSION: Endoscopy, has gained popularity in most surgical fields. We found that the available standard equipment used for TMJ arthroscopy can be used for exploration and extraction of calculi from the salivary ductal system.
We present four individuals with Gerodermia Osteodysplastica in a Jewish family from Morocco confirming the autosomal recessive inheritance of the disorder. Three previously unreported findings are described: a) enlarged funnel-shaped mandibular lingula; b) extension of the mandibular premolar and molar roots below the inferior dental canal, and of the second molars into the lower border of mandibular cortical bone; and c) hypercementosis of the maxillary incisors and mandibular molars surrounded by a radiolucent halo in several teeth. The facial deformity resulting from maxillary hypoplasia and mandibular prognathism was corrected by orthognathic surgery: Le Fort I maxillary osteotomy and vertical mandibular osteotomy.

Fifteen patients with mandibular fractures related to stone-throwing incidents are presented. Three illustrative cases are discussed in detail. Criteria for selecting management by early surgical intervention or a conservative approach are discussed. The ultimate aim in management is to preserve the greatest possible amount of function with the least risk and morbidity for the patients.

This study discusses the satisfactory CO 2 laser treatment of solar keratosis on Eastern European emigrants to Israel. It offers a comparison between cold blade vermilionectomy based on previous data and experience and reports postoperative results concerning cosmetic appearance and function of the lip.
An unusual case of pneumomediastinum caused by subcutaneous emphysema occurring after the use of hydrogen peroxide solution during root canal treatment is described in a 30-year-old man. A thorough search of the available literature failed to reveal similar cases. A review of the literature, including pathogenesis, clinical and radiographic features, and management of this condition, is presented.
Burns of the oral cavity may be caused by prolonged use of certain drugs by the patient or by incorrect use of caustics by the dentist. Unwillingly-acquired self-inflicted injuries are also encountered, such as caustic ingestion (out of curiosity or by accident), excessive consumption of fresh fruit and fresh fruit juice, and wrong oral hygiene practice. Our experience with six infrequent and unfamiliar types of oral burns, caused by various components and material, is described and discussed.
Leukocytoclastic vasculitis, immune complex disorder (type III), is a skin disease with both an acute form characterized by bullae, vesicles and ulcerations, and a chronic form characterized by petechiae, macules and ulcerations. The disease presents certain systemic features including diffuse or focal glomerulonephritis and renal failure. The histopathologic characteristics of leukocytoclastic vasculitis in the skin appear primarily in small blood vessels and consist of an infiltration of inflammatory cells, leukoclasis, swelling of endothelial cells, occlusion of blood vessels, accumulation of fibrin and fibrinoid degeneration, as well as the presence of immune complexes in and around blood vessel walls. Although leukocytoclastic vasculitis is described as several diseases which can spread systemically, including the gastrointestinal tract and the kidneys, the manifestations of the disease in the oral cavity have not yet been reported. The present paper reports unique oral lesions in a 38-yr-old woman, diagnosed as leukocytoclastic vasculitis, without any accompanying skin or systemic lesions.
Melkersson-Rosenthal syndrome consists of facial paralysis, facial edema, and scrotal tongue (lingua plicata). Granulomatous cheilitis, frequently associated with the name of Meischner, is generally accepted as a monosymptomatic form of the same syndrome, affects both sexes equally. The earliest manifestations usually develop in childhood or adolescence. We report a case in a 20-year-old woman in order to increase awareness of this entity, in both its classical and aberrant forms.
A simple, inexpensive, broadly applicable, and quickly applied substitute for the Hoffman apparatus is demonstrated. The procedure uses materials commonly available in hospital operating rooms and provides an excellent immobilization of transosseous pins in pedicled flap surgery and various open and closed fractures of long bones.
The authors report a case of Oculo-cerebro-cutaneous syndrome. They believe it to be the first case so diagnosed in an adult, and, compare it with 10 previously published cases.

We have encountered infrequent and unfamiliar types of morbid conditions requiring plastic surgery. We present here our clinical experience with five illustrative cases and discuss the typical features of each condition and its treatment.
