The rates of these eruption-like movements were high and were consistent with reports that eruption is fastest at the time of emergence into the mouth. Once the tooth had attained its initial functional position, there was a significant reduction in the rates. Following administration of the hypotensive agent, hexamethonium, the emerging tooth showed a significant decrease in eruption rates. However, no change was observed for the tooth which had attained its initial functional position. These findings support the view that there are physiological differences at the eruptive and initial functional stages of eruption. The effects of hexamethonium on the erupting ferret canine differ from those reported for the erupting rabbit incisor. This may reflect differences in the eruptive processes for teeth of limited and continuous growth, although other evidence suggests similarities between these.
这些类似萌出的运动速率很高，这与萌出进入口腔时速度最快的报道一致。一旦牙齿达到其初始功能位置，速率就会显著降低。给予降压药六甲铵后，正在萌出的牙齿萌出速率显著下降。然而，已达到其初始功能位置的牙齿未观察到变化。这些发现支持了这样一种观点，即在萌出和初始功能阶段存在生理差异。六甲铵对正在萌出的雪貂犬齿的影响与报道的对正在萌出的兔子门牙的影响不同。这可能反映了有限生长和持续生长牙齿萌出过程的差异，尽管其他证据表明两者之间存在相似之处。
