CBCT对不同年龄组间下颌第三磨牙拔除风险的评估
|
Abstract:
摘要 目的:运用锥形束CT研究年龄因素对拔除下颌第三磨牙的影响,评价早期拔除下颌第三磨牙的风险性。方法:筛选2015年6~12月在我院就诊患者中符合纳入标准的锥形束CT图像,共选取150颗下颌第三磨牙,其中16~18岁组47颗牙齿,19~24岁组60颗牙齿,24岁以上43颗牙齿,测得3个年龄组中患者的下颌骨体高(a)、下颌骨体剩余高度(b)与下颌骨体高(a)的比值、牙齿至下颌神经管最短距离数据,并分析不同年龄组之间的差异性。结果:下颌骨体高3个年龄组间差异无统计学意义。3组间b/a比值以24岁以上组最大,其次19~24岁组,各组间两两比较均有统计学意义。在牙齿至下颌神经管最短距离方面,19~24岁组和24岁以上组均比16~18岁组大,有统计学意义;而19~24岁组和24岁以上组间无统计学意义。但是,3个年龄组间牙齿与下颌神经管紧密接触比率无统计学差异。结论:3个年龄组中19~24岁组拔除下颌第三磨牙可能相对最合适、风险最小
