| 摘 要： | 目的:探讨Propex根管测量仪临床操作中的具体细节,为更好的临床实践提供依据.方法:选取重度牙周炎需拔除的前牙150颗,分为三组:A组:牙髓活力正常者84例;B1组:牙髓无活力根尖周组织正常者37例;B2组:牙髓无活力根尖周组织有破坏者29例.以Propex根管测量仪和15号手用不锈钢K型锉测量工作长度,带锉拍摄X线片,拔牙后,观测锉尖端在根尖区位置.结果:锉尖端至解剖性根尖孔距离在A组与B1组两组间差别无统计学意义(P>0.05),两组在距解剖性根尖孔0.5mm-1mm;锉尖端至解剖性根尖孔距离A组与B2组以及B1组与B2组间差别均差异具有统计学意义(P<0.01),B2组即牙髓坏死合并根尖周组织有破坏时,距解剖性根尖孔大部分P<0.5mm,甚至穿出解剖性根尖孔.结论:Propex可准确定位生理性根尖孔,牙髓有无活力对定位无影响,但根尖周破坏时准确性降低.

| Abstract: | Objective:To study the clinical application of the Propex apex locator.Methods:One hundred and fifty anterior teeth suffered from serious periodontitis were divided into three groups:group A consisted of 84 cases with vital dental pulp;group B1 consisted of 37 cases with dead dental pulp and normal apical tissue;B2 consisted of 29 cases with dead dental pulp and abnormal apical tissue.Working length of each root canal was measured by Propex and k files.Then the X ray and extraction were taken.Following that... |
