Abstract: Veterinary practice commonly involves caring for domestic and companion animal. Since the trend of owning exotic pets is rapidly increasing, veterinarians often treat exotic patients as well. As a result, veterinarians are facing increased demands for specialized skills and knowledge. This article aims to provide a concise review of the anatomy of the vascular system in exotic animals and its relevance in clinical practice. Snakes, lizards and chelonians have 3-chambered heart with 2 atria and one partially divided ventricle whereas crocodiles have 4-chambered heart. It is important to consider these characteristics during the anesthesia in reptiles since blood shunting affects changes in blood pressure, oxygen level and other anesthetic parameters. In birds, the cardiovascular system is crucial in enduring the exhausting physical activities such as swimming, flying or diving and running. Birds have renal portal system which consists of cranial and caudal renal portal vein. The recommendation of avoiding drug application in the hindlimbs of birds is present for a long time. This is valid not only for birds, but for reptiles, amphibians and most fish. The ventricle of amphibians is trabeculated, which minimizes blood shunting through various anatomical and physiological features. During biphasic systole, the left and right side of the ventricle contract separately, directing blood in different parts of aortic arches. Due to the complexity of the exotic animals, thorough education added in veterinary curricula is needed. Keywords: amphibians, birds, cardiovascular, clinical, reptiles

Simple Summary The aim of this study was to analyze and compare the morphology of root canals in the carnassial teeth of German shepherds and mixed-breed dogs. Knowledge of the morphology of root canals is essential for a successful endodontic procedure. It has been determined that an apical delta, which represents a complex structure that consists of multiple cavities whose purpose is to allow the passing of nerves and blood vessels from the pulp cavity to the apex of the root, was present in 247 roots. There are four main types of apical delta. The most common type in superior fourth premolars was type II, with up to 10 apical ramifications, whereas type IIIA, with 10–20 apical ramifications, was most commonly present in inferior first molars. Abstract Root canal treatment of carnassial teeth in dogs is a common endodontic technique which aims to re-establish or maintain the health of the periapical tissues. In total, 43 dogs were used in this study. Root canal morphology was evaluated in 86 superior fourth premolars and 86 inferior first molars. Apical delta was present in 247 roots, while obliteration of the root canal was found in 11 roots. The most common type of apical delta of the roots of superior fourth premolars was type II, with up to 10 apical ramifications, while type IIIA, with 10–20 apical ramifications, was most commonly present in the roots of inferior first molars. Considering that knowledge of the morphology of root canals is essential for a successful endodontic procedure, the aim of this study was to analyze and compare the morphology of root canals in the carnassial teeth of German shepherds and mixed-breed dogs. Apical resection for the purpose of endodontic therapy of the superior fourth premolar and the inferior first molar is indicated at a length of 4 to 6 mm from the anatomical tip of the roots, which would completely remove the apical delta of these two teeth.
