EOTRH: A lovely 21 year old gelding presented with extensive EOTRH on upper incisors. When percussed, gelding had moderate sensitivity on upper incisors and mild sensitivity on lower incisors. Owner noted that gelding appeared to be in pain while eating. Radiographs were taken of Incisors where enlarged bulbous roots of the 6 incisors were noted. With sedation and regional anaesthesia, all 6 incisors were removed. Gelding has recovered nicely and appears to be more comfortable while eating. What is EOTRH?
Introduction:
Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) is a dental condition affecting the teeth of horses. This disorder involves the gradual resorption of tooth structure and abnormal cement formation, often leading to severe dental problems. Understanding EOTRH and its management is essential for maintaining a horse's overall health and well-being.
1. What is EOTRH?
Equine Odontoclastic Tooth Resorption and Hypercementosis, abbreviated as EOTRH, is a dental condition primarily found in older horses. It affects the incisors, canines, and sometimes premolars. EOTRH is a painful disease that can significantly impact a horse's ability to eat and maintain proper nutrition.
2. Causes and Risk Factors:
The exact cause of EOTRH is not fully understood. However, several factors may contribute to its development, including age, genetics, diet, and chronic dental issues. Older horses, especially those over the age of 15, are more susceptible to EOTRH. Additionally, certain horse breeds may have a higher predisposition to this condition.
3. Symptoms of EOTRH:
Recognizing the signs of EOTRH is crucial for early diagnosis and appropriate treatment. Common symptoms include:
- Tooth sensitivity and pain
- Swollen or inflamed gums
- Loose or mobile teeth
- Excessive salivation
- Difficulty eating or dropping food
- Reluctance to accept the bit or bridling issues
4. Diagnosis:
Diagnosing EOTRH involves a thorough dental examination by a qualified veterinarian. This may include dental X-rays, intraoral examinations, and palpation of the affected teeth to assess their condition and the extent of the disease.
5. Treatment and Management:
Management of EOTRH typically involves a combination of dental care and pain management. Treatment options may include:
- Tooth extraction: The affected teeth may need to be extracted to alleviate pain and prevent further progression of the disease.
- Pain management: Pain relievers and anti-inflammatory medications can help manage discomfort and reduce inflammation associated with EOTRH.
- Dental care: Regular dental check-ups and cleanings are essential to monitor the horse's oral health and address any potential dental issues promptly.
6. Prevention:
While EOTRH may not be entirely preventable, maintaining good oral hygiene through regular dental check-ups and a balanced diet can help minimize the risk of developing severe dental problems. Providing a diet that promotes dental health and avoiding excessive wear on the teeth can also contribute to prevention.
Conclusion:
Equine Odontoclastic Tooth Resorption and Hypercementosis is a challenging dental condition affecting older horses. Recognizing the symptoms and seeking prompt veterinary care is essential for early diagnosis and appropriate treatment. By understanding EOTRH and implementing preventative measures, horse owners can ensure their equine companions maintain optimal dental health and overall well-being.
