A 5.5-month-old male Shih Tzu with the unerupted maxillary deciduous canines and swelling of the alveolar mucosa was shown to have bilateral impacted deciduous canines by X-ray examination. The crown of the left deciduous canine was partially erupted from the jaw bone showing a unilocular radiolucent area around the crown, and a small amount of clear and mucous fluid was obtained by exploratory puncture, suggesting the presence of an odontogenic cyst. The impacted left deciduous canine was extracted and the cyst wall was removed with a curet, resulting in normal eruption of the left upper canine after treatment. Histopathology of the removed specimen revealed a cystic structure lined by the non-keratinized stratified squamous epithelium with bud-like proliferation, and the case was diagnosed as odontogenic eruption cyst.
