目前的理论喷发进行了审查和理论，涉及喷发的根尖周组织的血管是有利的。下面的证据支持这个理论. 1.埋藏的牙齿往往在周围组织增加血管分布的地方长出。在义齿下，当组织受到足够刺激导致充血时，它们会爆发。当用手指摩擦时，它们也会爆发，导致充血。根尖周组织的炎症导致牙齿萌出。2.在动物中，颌一侧交感神经支配的破坏导致永久性血管扩张，从而增加了萌出率。3.激素影响牙齿周围组织的血管分布。由于证据不确凿，还需要做更多的实验。爆发力很可能不是单一来源的，而是多种因素共同作用的结果。|| 摘要：G. E. Groth
Present theories of eruption are reviewed and the theory that relates eruption to the vascularity of the periapical tissue is favoured. The following evidence is given in favor of the theory. 1. Submerged teeth tend to erupt where the surrounding tissues are caused to increase their vascularity. Under a denture they will erupt when the tissue is irritated sufficiently to cause hyperaemia. They will also erupt when rubbed with finger to cause hyperaemia. Inflammation of the periapical tissue causes eruption of a tooth. 2. In animals the destruction of the sympathetic innervation on one side of the jaw causing permanent vaso-dilation increased rate of eruption. 3. Hormones influenced the vascularity of the tissues surrounding the teeth. As the evidence is not conclusive more experiments should be made. The eruptive force is probably not derived simply from one source but may be the result of many factors. || ABSTRACT AUTHORS: G. E. Groth
