【摘要】 目的探讨运动致牙外伤发生的规律以及影响其预后的因素。方法回顾分析2005—2009年在北京大学深圳医院就诊的因运动致牙外伤的945例患者相关资料,对运动中牙外伤发生原因、地点、年龄、性别、牙位、类型、时间、季节、牙外伤就诊时间、牙根发育状况与其预后之间的关系加以分析,并提出相关预防措施。结果运动致牙外伤的高发年龄段为20～30岁;男性明显高于女性;夏秋季节高于春冬季节;受伤原因以运动中碰撞或跌倒最为多见。最易受伤的牙位是上颌中切牙,以半脱位最为多见。外伤发生后24h内就诊的年轻恒牙预后较好。结论运动致牙外伤发生存在一定的规律,外伤后就诊时间是影响外伤牙预后的因素之一,使用护牙托可以降低运动致牙外伤的发生率。更多还原
