EOTRH Syndrome in Polish Half-Bred Horses - Two Clinical Cases.

The aim of this paper is to thoroughly describe the etiology, diagnostic processes and recommended treatment of equine odontoclastic tooth resorption and hypercementosis (EOTRH). It is a relatively recently described disease. Most recent reports show that it is a common problem involving older equine patients. The most common and significant symptom of EOTRH is oral pain. The main clinical signs include periodontitis and gingivitis with a gingival recession, alveolar bone protrusion, periodontic fistulas and soreness of the incisors. When establishing the final diagnosis, it is necessary to compare the results of the clinical and radiological examination, because in the early stage, the disease may not show any symptoms. Authors used two clinical cases of Polish Half-Bred horses to present some aspects of diagnostic and surgical techniques. The knowledge presented in the paper may be valuable for equine practitioners working in the field to achieve more beneficial outcomes and provide a higher level of welfare for their equine patients. Nevertheless, further research and observations are necessary, since the etiology of the disease remains unclear.
