Hierf\u00fcr wurden Verlaufsdaten des konservativen Managements analysiert und Parameter von potenzieller prognostischer Relevanz untersucht.<\/jats:p>\n                  <jats:p>Diese retrospektive Studie inkludiert 34 Meerschweinchen, bei denen zwischen 2019 und 2025 in der Tierklinik Posthausen erstmals makrodonte Backenz\u00e4hne diagnostiziert wurden. Die Diagnosestellung erfolgte anhand makroskopischer, endoskopischer und radiologischer Befunde, orientiert an in der Fachliteratur beschriebenen morphologischen Kriterien dieser Pathologie. Das konservative Management bestand aus wiederholten Okklusionskorrekturen in Allgemeinan\u00e4sthesie, erg\u00e4nzt durch eine analgetische Medikation und bedarfsorientierte Zuf\u00fctterung. Die Eingriffe wurden bei erneutem Auftreten zahnassoziierter Beschwerden regelm\u00e4\u00dfig wiederholt.<\/jats:p>\n                  <jats:p>Die Kohorte wies eine erh\u00f6hte Pr\u00e4valenz m\u00e4nnlich kastrierter Tiere auf (55,8%). Die meisten makrodonten Backenz\u00e4hne (73,7%) waren im Unterkiefer lokalisiert und betrafen die letzten beiden Zahnpositionen (70,2%). Multiple makrodonte Z\u00e4hne wurden initial bei 55,9% der Meerschweinchen diagnostiziert, zus\u00e4tzliche Riesenz\u00e4hne traten bei 2 Tieren 260 Tage nach Therapiestart auf. Die Zahl der durchgef\u00fchrten Okklusionskorrekturen variierte zwischen 1 und 36, mit Intervallen von durchschnittlich 51 Tagen, die sich im Therapieverlauf verk\u00fcrzten. Bei 44,1% der Meerschweinchen wurde die Therapie nach der ersten Okklusionskorrektur nicht fortgef\u00fchrt. Tiere mit mehreren Eingriffen wiesen eine mittlere \u00dcberlebenszeit von 394 Tagen auf. Es konnte keine negative Korrelation zwischen der mittleren \u00dcberlebenszeit und der Zahl makrodonter Z\u00e4hne hergestellt werden.<\/jats:p>\n                  <jats:p>Die Befunde unterstreichen die M\u00f6glichkeiten und Limitationen eines rein konservativen Managements makrodonter Backenz\u00e4hne.<\/jats:p>","DOI":"10.1055\/a-2773-8335","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T23:07:11Z","timestamp":1777072031000},"page":"80-92","source":"Crossref","is-referenced-by-count":0,"title":["Konservatives Management von makrodonten Backenz\u00e4hnen bei 34 Meerschweinchen (Cavia porcellus)"],"prefix":"10.1055","volume":"54","author":[{"given":"Karin","family":"Harder","sequence":"additional","affiliation":[{"name":"Tierklinik Posthausen eGbR Dres.
