目的探讨上颌尖牙阻生对邻近前磨牙牙根形态的影响。收集并分析所有受试者的CBCT数据。上颌前磨牙离根的患病率进行了比较，受试者与无阻生尖牙。结果尖牙阻生组上颌第一前磨牙离根率显著高于尖牙阻生组（P=0.046），而上颌第二前磨牙离根率无显著差异（P=0.780）。BIC组第一前磨牙阻生区牙根分离的发生率明显高于其他组（P
ObjectiveTo investigate the influence of maxillary impacted canines on the root morphology of adjacent premolars in a Chinese population.Subjects and MethodsA sample of 370 Chinese subjects with maxillary canine impaction and 370 control subjects were collected in this study. CBCT data of all subjects were collected and analyzed. The prevalence of separate-rooted maxillary premolars was compared between subjects with and without impacted canines. Then, the prevalence of separate-rooted maxillary premolars was compared between subjects with buccal canine impaction (BIC) and those with palatal impaction (PIC).ResultsThe prevalence of separate-rooted first premolars was significantly higher in the canine impaction group (P=0.046), but the prevalence of separate-rooted second premolars was not different (P=0.780). Furthermore, a significant higher prevalence of first premolar root separation was found on the impacted site in the BIC subgroup (P
