Mandibular periostitis ossificans in immature large breed dogs: 5 cases (1999-2006).

This case series describes clinical, radiographic, and histopathological features of mandibular swellings in 5 immature, large breed dogs. The dogs originated from different regions of the United States. In each case, intraoral dental radiography of the jaw swelling revealed a two-layered (double) ventral mandibular cortex. Biopsy was performed in 4 of the 5 puppies, revealing periosteal new bone formation. Resolution of the mandibular swelling was spontaneous in the 4 dogs available for follow-up examination. The authors postulate that the clinical, radiographic, and histopathological presentation of mandibular swelling in these 5 dogs is a distinct pathological entity consistent with an inflammatory condition of the maturing human mandible known as periostitis ossificans.

Dental radiology.

Dental radiology is the core diagnostic modality of veterinary dentistry. Dental radiographs assist in detecting hidden painful pathology, estimating the severity of dental conditions, assessing treatment options, providing intraoperative guidance, and also serve to monitor success of prior treatments. Unfortunately, most professional veterinary training programs provide little or no training in veterinary dentistry in general or dental radiology in particular. Although a technical learning curve does exist, the techniques required for producing diagnostic films are not difficult to master. Regular use of dental x-rays will increase the amount of pathology detected, leading to healthier patients and happier clients who notice a difference in how their pet feels. This article covers equipment and materials needed to produce diagnostic intraoral dental films. A simplified guide for positioning will be presented, including a positioning "cheat sheet" to be placed next to the dental x-ray machine in the operatory. Additionally, digital dental radiograph systems will be described and trends for their future discussed.

Interpretation of dental radiographs.

Interpretation of dental radiographs is fairly straightforward, with a handful of common patterns making up the majority of pathology. This article covers normal radiographic anatomy, endodontic disease, periodontal disease, neoplastic changes, tooth resorption, caries, and radiographic signs of oral trauma.

Bonded sealants for fractured teeth.

Dental fractures in veterinary patients are relatively common. Historically, very little treatment has been provided for these fractures. Because of the relatively thin layer of enamel present in canine and feline dentition, most fractures result in exposure of dentin and/or pulp. This article discusses the rationale and procedure for treatment of exposed dentin in vital (live) teeth. Correct case selection and treatment improve patient comfort and help decrease the chance of future endodontic involvement in these teeth. This procedure may be considered an entry-level restorative procedure. Once mastered, the materials and principles will allow the practitioner to branch into more sophisticated restorative procedures, such as composite restorations, auto-incline planes, and restoration of endodontic access sites.

Pain management and regional anesthesia for the dental patient.

Current standards of care in veterinary medicine dictate an adequate level of pain control for our patients. Effective pain control uses a proactive, multimode approach that starts with preoperative medications, includes the anesthetic protocol selected, and continues into the postoperative period. A basic understanding of the physiology of pain assists in selecting those agents and modalities best suited for individual patients. Analgesic drug selection and local anesthesia are both integral parts of pain control when performing surgery in the oral cavity. Local (regional) anesthesia plays an important part in the pain control of oral surgical patients. Regional anesthetic techniques are used for many common oral procedures, including extractions, periodontal flap surgery, treatment of traumatic injuries of the oral cavity, tumor removal, palatal surgery, periodontal therapy, and root canal therapy. This presentation will cover strategies for analgesia and the techniques and materials used in local/regional anesthesia in the oral cavity. Anatomic landmarks and guidelines for effective regional blocks will be covered.

Greater palatine island axial pattern flap for repair of oronasal fistula related to eosinophilic granuloma.

A Greyhound presented with eosinophilic granuloma lesions of the soft palate and oronasal fistula. Since other siblings had been known to also have oral eosinophilic granuloma, it was suspected that the dog reported here had a familial predisposition to develop the disease. Preoperative medical management consisting of anti-inflammatory and immunosuppressive therapy was required before surgical repair of the oronasal fistula. Multiple surgical techniques, including a greater palatine island axial pattern flap, were used to repair the oronasal fistula.

Recurrent ossifying epulis in a dog.

A seven-year-old neutered/male Siberian Husky-cross dog was referred for evaluation of a gingival mass. Two years previously, the referring veterinarian had resected an ossifying epulis from the same area between the maxillary left first and second premolars. The neoplasm recurred 4-months after the original surgery. En bloc resection provided tumor-free margins. An oral examination 12-months following surgery indicated no gross signs of recurrence.
