Novel treatment of equine odontoclastic tooth resorption and hypercementosis of incisor teeth in a 22-year-old Arabian mare.

Equine odontoclastic tooth resorption and hypercementosis is a rarely reported condition in the incisor and canine teeth of older horses. Histologically, there is internal and external resorption of the tooth with formation of excessive cementum. Once lesions become infected or supragingival this condition is very painful. The clinical manifestation, diagnosis and treatment of hypercementosis in an Arabian mare are described.

Traitement innovateur de la résorption dentaire odontoclasique et de l'hypercémentose de la dent incisive chez une jument arabe âgée de 22 ans. La résorption dentaire odontoclasique et l'hypercémentose représentent une affection rarement signalée des dents incisives et canines chez les chevaux âgés. Sur le plan histologique, il se produit une résorption interne et externe de la dent avec une formation excessive de cément. Une fois que les lésions deviennent infectées ou supra-gingivales, cette affection est très douloureuse. La manifestation clinique, le diagnostic et le traitement de l'hypercémentose sont décrits chez une jument arabe.(Traduit par Isabelle Vallières).

Use of a hard palate mucoperiosteal flap for rostral muzzle reconstruction in a dog after a traumatic premaxillary degloving injury.

OBJECTIVE: To describe a technique for reconstruction of the rostral aspect of the muzzle of a dog after traumatic amputation. STUDY DESIGN: Clinical report. ANIMALS: Adult female dog. METHODS: A 6-year-old, intact, female, mixed-breed dog was admitted for facial reconstructive surgery after traumatic amputation of the rostral aspect of the muzzle. The nasal planum and the rostral portion of the upper lips were missing. A hard palate mucoperiosteal flap and lateral labial advancement flaps were used to reconstruct the nasal philtrum and borders of the nares. RESULTS: This reconstructive technique resulted in adequate nostril function and an acceptable cosmetic outcome. One naris developed partial obstruction with granulation tissue that may have occurred because of a lack of circumferential nasal mucosa to appose the skin on that side. CONCLUSION: The mucoperiosteum of the hard palate can be used to reconstruct the rostral aspect of the muzzle after traumatic amputation, resulting in an acceptable cosmetic outcome.
