Prosthetic reconstruction of broken canine teeth in dogs with use of cast metal posts.

Prosthodontic treatment, especially restorations of fractured teeth in small animals, has been the subject of many veterinary dental analyses in relation to techniques of endodontic treatment, preparation and cementation, as well as the general principles of prosthodontic treatment. The purpose of this paper is to present a previously undescribed method of all-in-one crown and root prosthetic restoration of fractured teeth in large dogs, together with a thorough analysis of the drawbacks, which may help veterinary dentists to use an evidence-based approach when deciding on the type of treatment for their patients with tooth fractures.

The effect of lateral electrical surface stimulation (LESS) on motor end-plates in an animal model of experimental scoliosis.

The treatment of idiopathic scoliosis is challenging because of its diverse etiology, age of onset, and long duration of intensive treatment. We examined the effect of lateral electrical surface stimulation (LESS) in an animal model of experimental scoliosis (ES) assessing the number of motor end-plates (MEPs) as a study end-point. The control group (n=5) was adapted to the experimental apparatus without stimulation, whereas ES was induced in rabbits by one-sided LESS of the longissimus dorsi muscle (LDM) for a duration of 2 months. The ES group (n=5) were subjected to a short-term corrective electrostimulation applied at the contralateral side of the spine compared to the previous LESS stimulation for 2 h daily for 3 (n=5) or 6 months (n=5). Another group of ES rabbits was subjected to a long-term corrective electrostimulation applied for 9 h daily for 3 (n=5) or 6 months (n=5). LESS applied for 2 months (ES), significantly increased the number of MEPs in LDM. The short-term corrective electrostimulation for 3 months resulted in an increased number of MEPs. However, a decrease was observed in the animals treated for 6 months. The long-term corrective electrostimulation for 3 months did not change the density of MEPs in the LDM, but for 6 months the number of MEPs in the LMD significantly decreased by ES and control groups. Thus, the results of the present study clearly show that the short-term LESS is able to influence both the number of MEPs and the effectiveness of muscle correctional adaptation in a more efficient and harmless manner than the long-term procedure.

Monocytic ehrlichiosis in dogs.

Ehrlichiosis is the multiorgan infectious disease caused by small, intracellular rickettsias from the genus Ehrlichia. These microorganisms are known as an etiologic factor of infections world wide in humans and in different species of animals. Dog ehrlichiosis can be caused by several species of Ehrlichia attacking different groups of blood cells, but most often an infection by Ehrlichia canis is diagnosed with special relation to monocytes. A vector for E. canis are Rhipicephalus sanguineus and Ixodes ricinus, commonly occurring in Poland. Disease caused by E. canis is known as Canine Monocytic Ehrlichiosis (CME). The disease most often has an asymptomatic course which can, in favourable circumstances, run into acute or chronic forms. The acute form of CME proceeds usually with fever, apathy, weakness and accompanying respiratory symptoms, lameness and disturbances in blood coagulation. In laboratory examinations thrombocytopenia, anemia and leucopenia are ascertained. The chronic form of CME proceeds among gentle, unspecific symptoms which may last even 5 years. The CME diagnosis is difficult and often demands parallel different diagnostic methods. A medicines of choice in the ehrlichiosis treatment are antibiotics from the group of tetracyclines, given at least for 28 days. They are largely efficient during treatment of the acute CME, causing the quick improvement. Instead, in the case of chronic form, answer for treatment can be weak, and cases of resistance to antibiotics ave known.

Restoration of fractured canines in ferrets after one-step root canal treatment.

This article describes a one-step root canal treatment and restoration of canine teeth in ferrets. Standard brass posts were used for the reconstruction of the teeth. The procedures were performed by dentists according to all rules and procedures used in root canal treatment in humans. The teeth were immediately restored anatomically. The procedures were successfully performed in four ferrets aged between 6 and 20 months of age, in three upper and one lower canines.

A clinical evaluation of glass-fibre posts and restorative materials used for the reconstruction of fractured canines after one-step root canal treatment in cats.

This article describes a procedure for a one-step root canal treatment and the subsequent restoration of fractured canine teeth in cats. Standard glass fibre posts were used in the reconstruction of the teeth which were then divided into two groups and restored anatomically using two different composite materials. The procedures were successfully performed on six cats. The subject teeth were four upper and two lower canines.
