目的探讨局部注射地塞米松对下颌第三磨牙拔除术后不适的影响。方法选择因下颌第三磨牙阻生来门诊治疗的患者45例(男23例,女22例),随机分为三组,每组15例。实验组一在拔牙前粘膜下局部注射地塞米松注射液1 m L,实验组二在拔牙后粘膜下...目的探讨局部注射地塞米松对下颌第三磨牙拔除术后不适的影响。方法选择因下颌第三磨牙阻生来门诊治疗的患者45例(男23例,女22例),随机分为三组,每组15例。实验组一在拔牙前粘膜下局部注射地塞米松注射液1 m L,实验组二在拔牙后粘膜下局部注射地塞米松注射液1 m L,对照组仅注射生理盐水1 m L。测量术前、术后第二天、术后一周的肿胀和开口受限情况。结果术后第二天,实验组肿胀程度低于对照组,实验组之间无显著性差异。术后一周,各组间肿胀程度均无显著性差异。术后各组间张口受限程度无显著性差异。结论局部注射地塞米松可有效减轻第三磨牙拔除术后短期内肿胀程度。拔牙前给药操作更加便利。展开更多
We establish the concept of shapes of functions by using partial differential inequalites. Our definition about shapes includes some usual shapes such as convex,subharmonic,etc.,and gives many new shapes of functions....We establish the concept of shapes of functions by using partial differential inequalites.
