Jaw lesions resulting from renal hyperparathyroidism in a young dog--a case report.

A five-month-old male Labrador retriever presented with massive bilateral jaw and facial swelling. Ulcers were found on the buccal mucosa and palate, and the jaws were flexible on firm palpation. The dog could eat only soft food and was underweight. Renal hyperparathyroidism was diagnosed based on serum chemistry screen, parathormone concentration, radiological findings and histopathology. The dog was euthanatized because of an extremely poor prognosis.

Masticatory muscle myositis.

This report examines a case of masticatory muscle myositis in a dog. Inflammatory disorders can affect the muscles of mastication. Two types of inflammatory myopathies have been described. The histopathology and immunochemical features of this case suggest an immune mediated basis for this disorder. The diagnosis and treatment are described for this immune mediated inflammatory myositis.

Feline dental resorptive lesions.

Resorptive lesions in feline teeth are frustrating. Despite a number of studies, there is as yet no satisfactory, clear-cut explanation for the cause, high prevalence, and recent emergence of this lesion, and experience with treatment has identified more problems, rather than indicated a successful management regime.

Etiopathogenesis of feline dental resorptive lesions.

There are several factors in the etiopathology of feline resorptive lesions. They may be considered as local immune-response mediating cell and humoral factors; release of biochemical components in dental and paradental tissues to attract odontoclasts; mechanical stress, including occlusal mechanism; and local and systemic calcium regulation, including remodeling of mineralized tissue and dietary intake of calcium.

Feline dental resorptive lesions. Prevalence patterns.

Surveys were carried out in cats presented for dental examination in the Netherlands (432 cats) and in the United States (78 cats). In 62% of the Dutch cats and 67% of the US cats, resorptive lesions were present. In the Dutch study, Asian Short-hair (principally Siamese) cats were most commonly involved, and male cats were more commonly affected than females. The most commonly affected teeth were the fourth maxillary premolar and the mandibular premolar and molar teeth.

Craniofacial development and growth in the dog.

Numerous types of veterinary orthodontic treatments are reported in papers and during meetings, however little is generally known concerning craniofacial growth in dogs. Most statements in veterinary dental publications are drawn from human-oriented studies. This makes decision making in veterinary orthodontics difficult. The purpose of this paper is to review studies of craniofacial growth performed in dogs.

Diagnostic approach to malocclusions in dogs.

Malocclusions may be associated with any of the cranial shapes recognized in dogs. Orthodontic treatments for malocclusions are frequently reported. However, these reports often lack a diagnostic plan and use confusing terminologies. The purpose of this paper is to describe, using standardized terms, a diagnostic approach to the most common malocclusions found in dogs.

The Angle classification system of malocclusion: is it appropriate for use in veterinary dentistry?

Classifications of malocclusions in dogs have superficially followed the Angle's system. Since teeth anatomy and occlusal relationships are not the same for dogs as for humans, the use of the Angle's system can be misinterpreted. The proposal for a system for classification of malocclusions specific to the dog is presented with a discussion of the Angle's classification of malocclusions.

Lipid composition and biosynthesis in the gingiva of the domestic cat.

Periodontal disease in the domestic cat may assume debilitating and serious consequences; however, little is known of the biochemical composition or metabolism of feline gingiva in health or disease. In this report the chemical composition and metabolism of gingival lipids from inflamed an non-inflamed sites is presented and compared to other species with naturally occurring periodontitis. The neutral and phospholipid composition of feline gingiva was found to be distinct from that of porcine and human. As a measure of de novo lipid synthesis, the total incorporation of 14C-acetate into fractionated lipid components was determined and revealed an approximate 2 to 3 fold decrease in inflamed versus non-inflamed gingiva. The decrease in 14C-acetate incorporation appeared to result from a 2-fold increase in free acetate pools in inflamed compared to non-inflamed gingival samples, since total lipase and phospholipase activity were comparable in inflamed and non-inflamed gingiva and total lipid composition was not changed between inflamed and non-inflamed sites. These data are similar to those reported for periodontally involved human gingival tissue and suggest a common effect of periodontal inflammation on lipid metabolism in both species.

Spirochetes in periodontal disease in the dog: a review.

The importance and the role of spirochetes in periodontal disease is controversial since the means to study these particular bacteria are limited. Because of specific requirements for growth, spirochetes are difficult to culture. Spirochetes could have profound effects on the perpetuation of periodontal disease. A review of the literature related to spirochetes is described.

Anaerobes in periodontal disease in the dog: a review.

As anaerobic sampling and culture techniques improved, the documented prevalence of anaerobic bacteria in periodontal disease has increased. The anaerobic bacteria have become more well-known in humans and consequently in dogs, since this species is a major model in periodontal studies. A review of the literature related to anaerobic flora is described.

Aerobes in periodontal disease in the dog: a review.

Periodontal disease has been shown to be caused by bacteria. Periodontal inflammation results as the plaque bacteria change from a predominantly non-motile, Gram-positive, aerobic coccoid microbiotal flora to a more motile, Gram-negative, anaerobic, rod-shaped flora. A review of the literature related to aerobic flora is included. The important effects of aerobic flora as well as their importance in contributing to periodontal disease development is reported.
