Recent studies on prenatal innervation of the jaws have shown that three separate main innervation paths, constituting three bilateral neural developmental fields (incisor field, canine/premolar field, molar field) exist in each jaw. In this communication the sequences in which the fields are innervated are indicated. These correspond to the sequences of formation of teeth and jawbone. The normal pattern of tooth agenesis is closely related to the neural fields, as the region within a single field were innervation occurs last is always the area most often affected by tooth agenesis. The initial manifestations of juvenile periodontitis also appear at the sites within the different fields where innervation occurs last. It is suggested that the pubertal growth of the alveolar process does not occur in these regions due to deficient innervation, and that the infection in juvenile periodontitis might be secondary to this regional lack of bone apposition.
最近关于颌骨产前神经支配的研究表明，每个颌骨中存在三条独立的主要神经支配路径，构成三个双侧神经发育区域（切牙区、尖牙/前磨牙区、磨牙区）。在本报告中指出了这些区域接受神经支配的顺序。这些顺序与牙齿和颌骨的形成顺序相对应。牙齿发育不全的正常模式与神经区域密切相关，因为在单个区域内神经支配最后发生的区域总是最常受牙齿发育不全影响的区域。青少年牙周炎的最初表现也出现在不同区域中神经支配最后发生的部位。有人提出，由于神经支配不足，这些区域的牙槽突青春期生长不会发生，青少年牙周炎中的感染可能继发于该区域骨附着的缺乏。
