| 摘 要： | 目的 了解Pont指数与牙列拥挤的关系,探讨牙列拥挤的发病机制。方法 分别选取91名正常人和
101名牙列拥挤患者为研究对象,测量其牙冠宽度和牙弓宽度,计算出双尖牙指数和磨牙指数,并对测量结果进行
分析。结果 (1)牙列拥挤组的双尖牙指数和磨牙指数大于正常组,二者具有显著性差异;(2)正常组的上颌
双尖牙牙弓宽度和上颌磨牙牙弓宽度存在性别上的显著性差异,但正常人与牙列拥挤患者的Pont指数均无性别
差异。结论 牙列拥挤的发生与Pont指数具有相关性。

| Abstract: | OBJECTIVE: The research aimed to analyze the significance of Pont Index in the dental crowding. METHODS: Respectively selected 91 normal occlusion persons and 101 dental crowding patients, measured every item of Pont Index of these two sample groups, and compared the results. RESULTS: The premolar index and molar index of dental crowding patients were obviously bigger than that of normal occlusion, and there was apparent significant difference. There was no significant gender difference of Pont Index either in normal occlusion or dental crowding patients. Whereas there was significant gender difference of premolar arch width and molar arch width in normal occlusion. CONCLUSION: The occurrence of dental crowding is clearly related to Pont Index. |
