To investigate the frequency, sex differences and location of impacted maxillary canine in orthodontic patients.
Two hundred and fifteen patients (77 males and 138 females) with maxillary canine impaction were included in the study. The experimental group was gathered from the Department of Orthodontics, Peking University School and Hospital of Stomatology. CT scan images were evaluated. Chi-square test was used in the analysis.
The prevalence of maxillary canine impaction among Chinese orthodontic patients was 2.05%. The ratio between male and female was 1.8:1 and the ratio between buccal and palatal location was 2.1:1. Surgical exposure and orthodontic alignment had been predominant in such conditions. There was significant deference in the treatment between palatally impacted canine and buccally impacted one. More palatally impacted canines were extracted than buccally impacted ones.
There was significant difference in the treatment of maxillary canine impaction. More buccally impacted canines were found in Chinese patients, especially in female patients.
研究正畸患者上颌埋伏阻生尖牙的发生率、性别差异及位置。
本研究纳入215例上颌尖牙阻生患者(男性77例,女性138例)。实验组来自北京大学口腔医学院正畸科。对CT扫描图像进行评估。分析采用卡方检验。
中国正畸患者上颌尖牙阻生的患病率为2.05%。男女比例为1.8:1,颊侧与腭侧位置比例为2.1:1。在这种情况下,手术暴露和正畸排齐是主要的治疗方法。腭侧阻生尖牙和颊侧阻生尖牙在治疗上有显著差异。腭侧阻生尖牙拔除的比例高于颊侧阻生尖牙。
上颌尖牙阻生的治疗存在显著差异。在中国患者中,尤其是女性患者,颊侧阻生尖牙更为常见。
