The variability of the closest speaking space (CSS) was compared to that of interocclusal distance (IOD) in the anteroposterior and mediolateral planes. Data were obtained from 30 dentulous subjects during two recording sessions using a mandibular kinesiograph set to display the frontal and sagittal planes. The two variables were measured in random order 20 times each. Mean variances were compared using a paired t test. The difference between the mean variances was statistically significant (P less than 0.05), with a greater value for CSS, only on the mediolateral projection. The small numerical value of this difference, however, makes any inference of clinical signifiance questionable.
在前后平面和内外侧平面上，比较了最接近的说话空间（CSS）与牙合间距离（IOD）的变异性。使用设置为显示额平面和矢状平面的下颌运动描记仪，在两次记录过程中从30名有牙受试者获取数据。两个变量以随机顺序各测量20次。使用配对t检验比较平均方差。平均方差之间的差异具有统计学意义（P小于0.05），仅在内外侧投影上，CSS的值更大。然而，这种差异的数值较小，使得任何关于临床意义的推断都值得怀疑。
