【摘 要】目的：采用一定统计学方法调查某医学院学生偏侧咀嚼和在安氏错颌分类系统下错颌的发生率，进而分析这两者之间的相关性。方法：通过对300名芜湖皖南医学院在校生进行偏侧咀嚼筛查，标准口腔检查，口腔相关问卷调查，继而对偏侧咀嚼以及安氏错颌分类系统相关性进行分析。结果：根据统计学结果分析，有偏侧咀嚼的学生占调查总数的58.00%，在安氏错颌分类系统（包括安氏错颌分类系统Ⅰ，Ⅱ和Ⅲ类）下有错颌的学生占调查总数的41.00%，同时有偏侧咀嚼和错颌的学生占调查总数的20.00%；有错颌的学生偏侧咀嚼的发生率明显比没有错颌的学生高；并且偏侧咀嚼与安氏错颌分类系统相关性之间有统计学意义（在0.01水平上显著相关，具有统计学上的意义）。结论：偏侧咀嚼和安氏错颌分类系统具有某种相关性，这次调查中皖南医学院的学生具有在安氏错颌分类系统下错颌的偏侧咀嚼发生率较没有错颌的学生高。因此，在防治偏侧咀嚼中，对治疗安氏错颌分类系统下的错颌需要引起高度重视。

【Abstract】Objective：The purpose is to investigate incidence of unilateral mastication and the class malocclusion system， and to analyze the relationship between unilateral mastication and the class malocclusion system.Methods：By means of unilateral mastication examination，standard dental detection and questionnaire survey in students（300） among Wannan Medical College in Wuhu，then analyzing unilateral mastication and the class malocclusion system correlation.Results：According to the statistics，students with unilateral mastication had a 58.0%，students with the class malocclusion（including the class malocclusionⅠ，Ⅱand Ⅲ） had a 41.0%，students with both unilateral mastication and the class malocclusion had a 20.0%；students have the class malocclusion unilateral mastication prevalence Which was obviously higher than that is no.There was a significant positive between unilateral mastication and the class malocclusion system（which had a statistical significance）.Conclusion：unilateral mastication and the class malocclusion have a certain relevance，students in Wannan Medical College with the class malocclusion have higher unilateral mastication prevalence than that of none-the-class-malocclusion.So in the prevention of unilateral mastication，the significance of treating the class malocclusion should be highly valued.

大多数人使用左右两侧牙列咀嚼，这样能充分发挥全部牙齿的咀嚼功能，能利用食团、唾液等对牙面的摩擦、冲刷，起到自洁作用预防龋齿等各种口腔疾病。而且对颌骨和肌肉也有生理性刺激，这对处于生长发育的青少年尤为关键。但由于种种原因，例如有些青少年常常习惯于只用一侧的牙齿咀嚼，而另一侧牙齿则完全弃之不用，继而形成偏侧咀嚼习惯，从而造成多方面的危害[1]。……
