The investigations took place from October 2020 to December 2021.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a3\">\n<jats:title>METHODS<\/jats:title>\n<jats:p>Anamnestic data were collected using an owner-completed questionnaire. Horses underwent a thorough physical examination and CBC. The rostral oral cavity was clinically examined, and intraoral radiographs of the incisors were taken. Clinical and radiographic findings were scored. Based on the results, the study population was separated into \u201cEOTRH-affected\u201d and \u201cEOTRH-healthy\u201d horses. Both groups were compared to identify differences within the anamnestic factors. In case of inconclusive findings, some horses were classified as \u201csuspicious\u201d.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>The diagnosis of EOTRH was made in 72.2% (109\/151) of horses. The risk of contracting the disease increased with the age of the horse (<jats:italic>P<\/jats:italic> = .004). In addition, there was a predisposition for male animals (<jats:italic>P<\/jats:italic> = .032). Feeding, keeping, and dental treatments showed no significant influence, while place of birth seemed to influence horses developing EOTRH (<jats:italic>P<\/jats:italic> = .017).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>The results highlight how widespread EOTRH is among the German Icelandic horse population and the need for raising awareness of EOTRH, as many horses were not suspected of having EOTRH beforehand. Moreover, numerous etiological propositions exist, but, to date, no studies have investigated their relevance.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.23.05.0301","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T17:31:45Z","timestamp":1695317505000},"page":"S102-S107","source":"Crossref","is-referenced-by-count":7,"title":["Widespread prevalence of Equine Odontoclastic Tooth Resorption and Hypercementosis detected in German Icelandic horse population: impact of anamnestic factors on etiology"],"prefix":"10.2460","volume":"261","author":[{"given":"Melusine","family":"Tretow","sequence":"first","affiliation":[{"name":"Clinic for Horses, University of Veterinary Medicine Hannover, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna M.","family":"Hain","sequence":"additional","affiliation":[{"name":"Clinic for Horses, University of Veterinary Medicine Hannover, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Astrid","family":"Bienert-Zeit","sequence":"additional","affiliation":[{"name":"Clinic for Horses, University of Veterinary Medicine Hannover, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"issue":"7","key":"B1","series-title":"Equine Vet Educ","first-page":"386","article-title":"Equine odontoclastic tooth resorption and hypercementosis","volume":"30","author":"Hole SL","year":"2018","unstructured":"Hole SL, Staszyk C.
