The eruption mechanism is not fully understood. It is known that the dental follicle is essential and that experimentally provoked denervation influence the process of eruption. Accordingly, the purpose of this study was to elucidate the eruption pattern in a human population and relate this pattern to the pattern of jaw innervation. The eruption pattern was evaluated from the correlation between the emergence times of different teeth in the permanent dentition based on longitudinal data from a large national registry (12,642 boys and 12,095 girls). Correlations coefficients were generally high (>0.5) and higher between teeth within the same tooth groups (i.e. incisors, canines and premolars, and molars) than between teeth from different tooth groups. It was shown that the correlation in emergence of teeth closely followed the pattern of innervation of the jaws. Thus the study supported the hypothesis concerning a possible association between eruption and innervation.
牙齿萌出机制尚未完全明确。已知牙囊至关重要，且实验性诱发的去神经支配会影响萌出过程。因此，本研究的目的是阐明人类群体中的牙齿萌出模式，并将此模式与颌骨神经支配模式相关联。基于一个大型国家登记处的纵向数据（12,642名男孩和12,095名女孩），通过恒牙列中不同牙齿萌出时间之间的相关性来评估牙齿萌出模式。相关系数通常较高（>0.5），并且同一牙组（即切牙、尖牙、前磨牙和磨牙）内牙齿之间的相关性高于不同牙组牙齿之间的相关性。结果表明，牙齿萌出的相关性与颌骨神经支配模式密切相关。因此，该研究支持了关于萌出与神经支配之间可能存在关联的假说。
