摘　　要：目的比较上颌侧切牙先天性缺失患者和牙列完整患者的蝶鞍大小,评估鞍桥和上颌侧切牙先天性缺失之间是否存在联系。方法以上颌侧切牙先天性缺失患者作为试验组,牙列完整者作为对照组,每组各80例。利用Dolphin软件测量蝶鞍的大小,记录蝶鞍鞍桥的钙化程度。结果两组间的蝶鞍大小除长度以外差异均无统计学意义。试验组与对照组在鞍桥发生率之间的差异有统计学意义。但两组中鞍桥发生率以及蝶鞍大小的差异在性别之间均无统计学意义。结论与对照组相比,上颌侧切牙先天缺失患者的蝶鞍长度较长且鞍桥的发生率有所增加。Objective To investigate the association between sella turcica and maxillary lateral incisor agenesis by comparing the size of sella turcica between patients with congenital absence of maxillary lateral incisors and complete dentiton.Methods Patients were divided into two groups with 80 patients in each group:the experimental group included patients with agenesis of the maxillary lateral incisor;the control group consisted of patients with complete dentition.Dolphin imaging software was used to evaluate the size and record calcification in the bridge of sella turcica.Results Except for the length of sella turcica,no statistically significant difference was found in the size of sella turcica between the two groups.There was a statistically significant difference in the incidence of bridge between two groups.Statistically significant differences between gender were found neither in the frequency of sella turcica bridge nor in the size of turcica.Conclusion Patients with congenitally missing maxillary lateral incisors had a greater sella turcica length and an increased incidence of sella turcica bridge,compared to the control group.
