Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) is a progressive dental disease primarily affecting the incisor and canine teeth of horses, typically those over 15 years of age. This condition involves the resorption of dental structures, where the body’s own cells, called odontoclasts, break down and absorb the mineralized tissue of the teeth. Concurrently, hypercementosis occurs, which is an excessive production of cementum, a calcified layer covering the roots of the teeth. This abnormal cementum buildup can cause the teeth to become enlarged and deformed.

EOTRH is characterized by several clinical signs, including:

1. Pain and Discomfort: Horses may show signs of oral pain, such as reluctance to eat hard foods, dropping feed, or avoiding the bit during riding.
2. Swelling and Inflammation: Gums around the affected teeth may appear red, swollen, and inflamed.
3. Tooth Mobility: Affected teeth can become loose and wobbly.
4. Drainage Tracts and Abscesses: Infection may develop, leading to the formation of pus-filled tracts or abscesses around the tooth roots.
5. Behavioral Changes: Horses may exhibit changes in behavior due to pain, such as irritability or a reluctance to be handled around the mouth.

The exact cause of EOTRH is not well understood, but it is believed to be related to chronic inflammation, possibly triggered by factors such as periodontal disease, trauma, or an autoimmune response.

Diagnosis is typically based on clinical signs and radiographic examination, which can reveal the extent of tooth resorption and hypercementosis. Management options depend on the severity of the condition. In early stages, management may involve regular dental care, pain relief, and antibiotics if infection is present. In more advanced cases, extraction of the affected teeth is often necessary to alleviate pain and prevent further complications.

Early detection and management of EOTRH are vital for maintaining the oral health and overall well-being of affected horses. Regular dental check-ups by a veterinarian skilled in equine dentistry is essential for promptly identifying and addressing this condition.
