中国北方地区人群上颌第二磨牙融合根锥形束CT研究
|
Abstract:
摘要 目的:研究中国北方地区人群CBCT图像中上颌第二磨牙融合根分布规律及其内根管的形态特点。方法:从2014年1月~2015年12月青岛市口腔医院因治疗需要拍摄CBCT患者中筛选符合条件者,记录患者的性别、年龄、上颌第二磨牙融合根分型及其内根管的交联情况,将数据分组并进行统计学分析。结果:324名患者纳入实验,139人存在上颌第二磨牙融合根,共计222颗磨牙。研究表明不同年龄段融合根发生率有差异(P<0.05),其中35~50岁组发生率最高(70.9%);男女之间融合根发生率无统计学差异;融合根整体呈对称性分布;48.6%(108/222)存在根管交联,不同融合根内根管交联特点不尽相同。结论:上颌第二磨牙融合根在中国北方地区人群中发生率高,掌握其分布以及形态学特点对临床治疗具有参考价值
