【摘要】：目的:比较腭侧埋伏阻尖牙生和尖牙正常萌出患者的蝶鞍大小,检测鞍桥和腭侧埋伏阻生尖牙之间是否存在关联。方法:选择腭侧埋伏阻生尖牙患者的头颅侧位片作为实验组,共103例,尖牙正常萌出者作为对照组,共103例。测量蝶鞍的长度、深度、直径,依据蝶鞍的钙化程度将其分为Ⅰ、Ⅱ、Ⅲ型。结果:除蝶鞍深度外,蝶鞍长度、直径两组间比较差异均有统计学意义。实验组男性的蝶鞍深度大于女性,蝶鞍长度及蝶鞍直径男女无统计学差异。而对照组男性与女性间蝶鞍的大小比较均无统计学差异。实验组鞍桥部分和完全钙化的发生率分别为41.75%和15.53%,但性别间比较差异无统计学意义;对照组鞍桥部分和完全钙化的发生率分别为8.73%和4.85%。实验组鞍桥发生率是对照组的8.52倍。结论:腭侧埋伏阻生尖牙患者的蝶鞍长度、直径均较对照组大,其鞍桥的发生率显著增加,但无性别差异。
[Abstract]:Aim: to compare the size of saddle between palatal impacted canine and normal canine eruption, and to detect the correlation between saddle bridge and palatal impacted canine. Methods: 103 cases of experimental group were selected as experimental group and 103 cases of normal eruption of canine teeth as control group. The length, depth and diameter of Sella turcica were measured and divided into 鈪，
