Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a recently described painful and progressive condition of unknown etiology that occurs in middle-aged and geriatric equines. It predominantly affects the permanent incisor and canine teeth and, less commonly, the premolar and molar dentition. EOTRH was first reported in peer-reviewed literature in 2008, with subsequent publications of case reports, histological studies and retrospective case series. There have been few significant research developments related to this disease. The existing studies have primarily involved single case studies or small sample sizes, without control groups. This review aimed to report current information about EOTRH in terms of clinical, histopathological, diagnostic, radiological, and therapeutic aspects, by searching the available peer-reviewed scientific literature.
