上颌第3磨牙疾患及其并发症的关系

目的 探讨上颌第3磨牙的解剖位置特性与其并发症的关系及并发症的处理方法和拔牙操作时机.方法 对1995年至2010年拔除的8 131枚上颌第3磨牙的诊治情况进行回顾性研究.结果 8 131枚上颌第3磨牙中,引起张口受限1 062例(其中冠周炎628例,颊部糜烂308例,伴颊部新生物126例),食物嵌塞2 604例,龋坏或牙周炎1 654例,无症状者2 810例.经拔牙及局部治疗后,随访1月至5 a,局部症状消除,断根残留者无异常.结论 食物嵌塞、冠周炎、颊部糜烂、颊部新生物等是上颌第3磨牙的主要并发症;拔除无对颌或位置不正的上颌第3磨牙是治疗和预防由其引起的并发症的最佳有效方法.
