Abstract：
Ectopic eruption results from a disturbance in tooth development and eruption, leading to an erupted or non-erupted tooth being in an unexpected anatomical location. This retrospective case series describes the location, position, form, and clinical signs associated with ectopic eruption in dogs. Thirty-five dogs (46 teeth) were diagnosed with ectopic eruption at three clinical practices during 2017-2020. The cases were described in terms of the location, the development and eruption status, the clinical signs, the consequences, and the treatment performed. The collected data were statistically analyzed to establish possible ramifications. The results showed that the ectopic eruption in the evaluated cases involved permanent teeth, mainly located in the maxilla, and mostly unerupted. Those located in the mandible were significantly more impacted than those located in the maxilla. This study concluded that tooth crowding and malocclusion (39.1%), facial swelling (8.6%), and periodontal disease (8.6%) were associated with the presence of ectopic eruption, and consequently, treatment was required in the majority (65.2%) of cases.
摘要：
异位萌出是由于牙齿发育和萌出受到干扰，导致长出或未长出的牙齿处于意外的解剖位置。这个回顾性病例系列描述了地点，position,形式,以及与狗异位爆发相关的临床症状。在2017-2020年的三个临床实践中，有35只狗（46颗牙齿）被诊断为异位萌出。这些病例是根据地点描述的，发展和喷发状况，临床症状，后果,和进行的治疗。对收集的数据进行统计分析，以确定可能的后果。结果表明，在评估病例中，异位萌出涉及恒牙，主要位于上颌骨,而且大部分没有爆发。位于下颌骨的受影响明显大于位于上颌骨的受影响。这项研究得出结论，牙齿拥挤和错牙合（39.1％），面部肿胀(8.6%),和牙周病（8.6％）与异位喷发的存在有关，因此，大多数(65.2%)病例需要治疗.
