Equine odontoclastic tooth resorption and hypercementosis (EOTRH)

Definition:

struction and/or abnormal overgrowth

of the cementum, the yellowish outer

covering of the teeth and lining of the

infundibulum, below the gum line of the

incisors and/or canine teeth.

Signs:

an inflammatory de-

Pain and inflammation in and

around the front teeth and gums; ulcers

and other signs of infection may be pres-

ent. In later stages, the teeth may take

on a bulbous, roughened, cauliflower-like

appearance and loosen.

Causes: unknown. EOTRH appears

to result from inflammation in the gum

area, but the pathogenesis is not fully

understood.

Diagnosis:

signs of infection; x-rays are necessary

to determine the destruction and over-

growth of tissue beneath the gum line.

Treatment:

for EOTRH. Drug therapies, with antibiot-

ics, anti-inflammatory medications and/

or steroids, may delay progress of the

disease. Rinsing the gums topically with

chlorhexidine may reduce contamina-

tion and inflammation. As the pathology

advances to a severe stage, extraction is

the best option.
