EOTRH

 EOTRH  

Equine Odontoclastic Tooth Resorption and Hypercementosis  

What 
EOTRH is a disorder of the incisors (and possibly the canines) in the older horse. It is a slowly developing disorder in which some or all of the incisors are affected. The condition is described by a resorption (dissolution) of the tooth in combination with the formation of abnormal amounts of cement around the rootsThere is a form in which the teeth become very brittle (with a lot of gum reactionand a form in which the roots of the tooth become extremely thick (often with much less gum reaction). Of course, all mixed forms also occur 

Symptoms  
Horses suffering from EOTRH are characterised by one or more of the symptoms listed below;  

 abnormal amount of calculus  

 Thickening of the incisors at root level  

 Ignited and reactive gumspossibly small fistulas (openings 

 Loose incisors  

When EOTRH has affected several teeth and/or has reached a more advanced stage, it becomes a very painful condition. These horses often eat with difficultysalivate a lot and stink from the mouth 

Cause  
The exact cause of EOTRH is not yet known. It is an autoimmune disorder (the body attacks its own incisorsso to speakthat occurs more (but not exclusively) in older horses (+14yo) and is also more common in some breeds. The Icelandic appears to be particularly susceptible to this disease 

Diagnosis 
Oftenthe clinical signs are sufficient to make a diagnosis, and an X-ray examination of the incisors may clarify the extent of the condition. 

Treatment & Prognosis 
Unfortunatelyto this date, there is no drug treatment that can stop or cure the disease processExperimentallycorticosteroids seem to be able to slow down the process. In most cases, thereforethe affected incisors need to be extractedOnce the bad teeth have been extracted, these horses can eat 'normallyagainHorses without incisors can eat amazingly well and can easily 'cut' off grass with the tongue and palate. 

Horses with all incisors removed will often leave the tip of their tongue hanging out of their mouth. For most horseshoweverthis does not have to be anything more than a beauty flaw.
