Forty-five mixed breed dogs were evaluated for the presence and extent of periodontal disease. Histopathology was performed on samples lung, myocardium, liver, kidney, tonsil, spleen, submandibular lymph node tracheobronchial node. Mitral valves grossly. Statistical analysis used to determine if there a relationship between disease histopathologic changes in tissues examined. In forty-five studied, an association found myocardium (papillary muscle), liver.

Thirteen hundred and fifty dogs were examined under anesthesia at veterinary hospitals in the USA Canada. Periodontal health was recorded detail. Teeth frequently absent (particularly lower third molar, upper first premolars, incisor teeth). Calculus most extensive on fourth premolar molar teeth. Missing teeth, mobility of remaining extent calculus gingival inflammation, furcation exposure attachment loss all more common small compared with larger dogs, older younger dogs.

Abstract Objective —To determine whether severity of periodontal disease (PD) was associated with systemic health indices in dogs and treatment PD altered indices. Design —Prospective cohort study. Animals —38 dogs. Procedures —Healthy clinical signs were included the Physical examination, serum biochemical analysis, a CBC, urine evaluati on, measurement C-reactive protein (CRP) concentration, microalbuminuria test performed prior to PD. All tooth roots scored for gingivitis attachment loss,...

The efficacy of brushing the teeth beagle dogs in a randomized, controlled, blinded study design using clearly-defined technique was evaluated for 4 frequencies: daily, every other day, weekly and week, compared with no control group dogs. All were fed standard dry kibble diet during study. Standard plaque, calculus, gingivitis indices used to score teeth. A ‘clean tooth’ model used. No gingival or non-gingival lacerations signs injury oral tissues found at end 28 day trial period. Brushing...

Height measurements of the mandible and mandibular first molar tooth were obtained from 234 dogs. Statistical analysis was performed to determine possible associations between these body weight, sex, age, condition. There a statistically significant association mandible: height measurement ratio weight (p < 0.0001) in all groups. Small dogs had proportionally larger teeth relative compared with This relationship may contribute an increased susceptibility small for periodontitis subsequent...

Twenty-four dogs with nasal aspergillosis were treated enilconazole (10 mg/kg bid for 7-14 days) administered topically through tubes surgically implanted into the chambers. Aspergillosis was eliminated in 19 over a median follow-up period of 18 months. Another dog died, but at necropsy there no evidence causative fungus. Two four that not cured had infection periorbital soft tissues. An additional seven received 6 weeks ketoconazole (5 PO) and therapy topically. Six these disease-free 35...
