To assess the presence and possible associations between the type of dental anomalies and maxillary and mandibular canine impactions in orthodontic patients treated for canine impaction, panoramic radiographs of orthodontic patients treated for canine impaction were assessed for the presence of associated dental anomalies. A random sample of orthodontic patients without canine impaction matched for age and gender served as controls. Descriptive and exact inferential statistics were implemented in order to assess potential associations between canine impaction and dental anomalies. A total of 102 orthodontic patients with 70 maxillary (MaxCI) and 32 mandibular (ManCI) canine impactions were assessed. The control group included 117 orthodontic patients. Dental anomalies were present in more than 50% of patients with impacted canines and in 20% of the controls. Tooth agenesis was significantly more common in the MaxCI group when compared to the ManCI group, while supernumerary teeth and canine transmigration were registered more often in the ManCI group. When compared to the control group, peg-shaped maxillary lateral incisors and tooth agenesis were significantly more prevalent in the MaxCI group, while canine transmigration, supernumerary teeth, the agenesis of mandibular incisors and tooth transpositions were significantly more prevalent in the ManCI group. The impaction of other teeth was significantly more common in both canine impaction groups when compared to the controls. The prevalence of dental anomalies in orthodontic patients with impacted canines was higher than in orthodontic patients without canine impaction. Different types of tooth anomalies were found in the MaxCI and ManCI groups.
为了评估在接受犬牙阻生治疗的正畸患者中，牙齿异常类型与上颌和下颌犬牙阻生之间的存在情况及可能的关联，对接受犬牙阻生治疗的正畸患者的全景X线片进行评估，以确定是否存在相关牙齿异常。选取年龄和性别匹配的无犬牙阻生的正畸患者随机样本作为对照。实施描述性和精确推断性统计，以评估犬牙阻生与牙齿异常之间的潜在关联。共评估了102例正畸患者，其中上颌犬牙阻生（MaxCI）70例，下颌犬牙阻生（ManCI）32例。对照组包括117例正畸患者。超过50%的犬牙阻生患者和20%的对照组存在牙齿异常。与ManCI组相比，MaxCI组牙齿缺失明显更常见，而额外牙和犬牙移位在ManCI组中更常出现。与对照组相比，MaxCI组中钉状上颌侧切牙和牙齿缺失明显更普遍，而犬牙移位、额外牙、下颌切牙缺失和牙齿换位在ManCI组中明显更普遍。与对照组相比，两个犬牙阻生组中其他牙齿阻生明显更常见。有犬牙阻生的正畸患者中牙齿异常的患病率高于无犬牙阻生的正畸患者。在MaxCI组和ManCI组中发现了不同类型的牙齿异常。
