A 2.5-year-old intact male Irish setter was presented for a draining tract associated with the right mandibular first molar tooth (409). Conscious oral examination yielded two draining tracts associated with the right mandibular first molar tooth. No obvious missing teeth or other gross abnormalities associated with the oral cavity were observed. Upon anesthetized radiographic evaluation, the presence of an unerupted, abnormally positioned, supernumerary premolar tooth was observed. The following article describes the extraction of the right mandibular first molar tooth (409) as well as the unerupted supernumerary premolar tooth with associated supernumerary root and the diagnostic approach taken for this uncommon abnormality.
一只 2.5 岁的未绝育雄性爱尔兰塞特犬前来就诊，右下颌第一磨牙（409）有一窦道。有意识的口腔检查发现右下颌第一磨牙有两个窦道。未观察到与口腔有关的明显缺失牙齿或其他明显异常。在麻醉放射学评估时，发现有一颗未萌出、位置异常的额外前磨牙。本文描述了右下颌第一磨牙（409）的拔除，以及未萌出的额外前磨牙及其相关的额外根，以及针对这种罕见异常的诊断方法。
