Rounds With Doc T – “EOTRH” – 2021 March 28th
It was great to have you join us for this month’s Rounds With Doc T on EOTRH ( Equine Odontoclastic Tooth Resorption and Hypercementosis ) If you missed the live meeting don’t worry you can watch the replay and join the discussion below.
Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) is a new disease of horses affecting the health of the incisor and canine teeth of all horses. I describe this disease as well as a unique perspective on its cause (autoimmune). I also give observational evidence for a treatment to stop further inflammation and damage.
Note: I made a mistake (actually spellcheck did this) in the word used on this title page for the video. The word “odontoblast” should be “odontoclast.” The “blast” cells lay down more tooth and the “clast” cells resorb tooth.

Hi Matt,

Hey Jenny yes it was, I just updated the link 🙂
Let us know what you think once you have a chance to watch it

Hi Matt,
Thanks, I found the it all very interesting. I’d never heard of EOTRH until I found your website. I’m amazed that something that has such a profound affect on the incisors doesn’t affect the molars and that no-one knows the cause.
Do horses in the wild get it?
Thank you for these talks and podcasts, it’s giving me a much better understanding as to how best to care for my horses.

@Jenny – Thanks and I’m glad you are enjoying them.
I am assuming that the reason the cheek teeth are not affected is because the opening of the salivary ducts are located next to the cheek teeth. When the grain is mixed with the saliva there is a better association between the lectins and the mucopolysaccharides that bind to them. It is my hypothesis that there is no association at the incisors especially between the incisors and the lips. In essence, horses affected with EOTRH are “dry mouth” at the incisors.
I can’t think of a way to test this hypothesis nor is there any profit to be gained by figuring this out and therefore little to no research would be funded for this.
It is hard to find “wild” horses as most are feral. 1) this obvious issue was not in the text books in the 1980’s – why? and 2) it should be a relatively easy history process where anyone seeing EOTRH can correlate it to feeding grain in the past. To my knowledge (though it is only a recent effort on my part), I am asking every horse owner with evidence of EOTRH if grain has ever been fed. To date grain has been found somewhere in the diet of the horse. For one it was years earlier but for almost all I have asked, grain was being currently fed.
Correlation does NOT equal causation so more detailed data is needed. Preferably, can we induce EOTRH with grain – and if so, how many are susceptible? However, I am seeing in in an increasing number of horses every month. Out of the last 300 horses I think I saw 8 cases – or a prevalence of 2.6%.

OK – completely realize this is my dumb – but where is the link? i am lost in an infinite loop 😀
-
I can’t see it here either

@Caroline and @Kerry – We all need to laugh at my absolute brain loss. Honestly I know I did this – added the link days ago. Where it went I have no idea but I can assure you all, you are NOT crazy.
The link and video are now (April 3rd) in the original post Matt made at the top of this discussion. I see it but if it should disappear…. please let me know.
Growing pains….
