Abstract
Dentigerous cysts occur infrequently in dogs and they should be a primary consideration in young dogs presented with oral swelling in the edentulous area. They are even less common in cats compared to dogs. Classification of lesions in animals is not very different from those described in humans. Dentigerous cysts are most frequently seen affecting the mandibular first premolar area with unerupted mandibular first premolar teeth. This report describes the clinical case of a four-year-old female Slovakian Chuvach that suffered from long-term difficulties associated with epistaxis and swelling of the facial area. Computed tomography revealed a cyst-like structure associated with an intra-nasal canine, prompting the suspected diagnosis of an odontogenic cyst. Histopathological examination of tissues obtained during the subsequent surgical procedure confirmed the diagnosis of a dentigerous cyst.
Highlights
In small animal clinical practice, it is very important to thoroughly examine the oral cavity since incomplete dentition is a common finding
This report describes the clinical case of a dog with intruded maxillary canine teeth where one of the intruded canines was associated with a dentigerous cyst
The patient had responded to periodic antibiotics and non-steroidal anti-inflammatory drug therapy evidenced by a reduction of the nasal discharge and swelling which recurred after medication was terminated
Summary
In small animal clinical practice, it is very important to thoroughly examine the oral cavity since incomplete dentition (hypodontia) is a common finding. Dentigerous cysts are the most common odontogenic cysts in small animal practice (Verstraete et al 2011). These cysts are usually associated with crowns of permanent unerupted teeth (Menditti et al 2018) and develop from the epithelial remains of the “Malassez (Menditti et al 2018), remnants of odontogenesis that become stimulated by retained teeth (D’Astous 2011). A four-year-old intact female Slovakian Chuvach weighing 30 kg, was referred to the Small Animal Clinic of the University of Veterinary and Pharmaceutical Sciences Brno. Clinical examination showed a bilateral nasal swelling about halfway between the medial canthus of the eyes and nostrils. The patient was reluctant to be clinically examined, and it was decided to continue the examination under general anaesthesia
