Equine odontoclastic tooth resorption and hypercementosis, radiographs

Intraoral radiographs of the upper (A) and lower (B) incisors in a 24-year-old mare with severe equine odontoclastic tooth resorption and hypercementosis. The mandibula and maxillary bone appear osteoporotic. The periodontal spaces are irregular and poorly defined. The roots have varying amounts of hypercementosis. The reserve crowns and roots have a moth-eaten appearance, consistent with odontoclastic tooth resorption.
