摘　　要：对吻磨牙(KMs)非常罕见,是指单一牙囊中包含方向相反、咬合面靠近的磨牙。KMs仅发生于完全阻生的下颌磨牙,常累及第三磨牙。这是一类有趣且罕见的牙阻生现象,目前发现其中少部分病例与代谢性疾病——黏多糖贮积症相关,具体机制尚不明确。学者们对KMs的发病机制给予了极大的关注,提出数种病因假说,然而并不能得到完整的解释。KMs的牙阻生形式较为独特,治疗选择面临诸多困惑。由于报道的病例较少,对其认识欠深入,其诊断和治疗亦常存在不同意见。本文对KMs的定义、分类、病因病理机制及与临床之间的关系等方面进行综述,以期提高口腔临床医生对KMs的认识,为其临床诊治提供参考。Kissing molars(KMs)represent a rare clinical event and used in describing impacted teeth contacting occlusal surfaces in a single follicular space and their roots pointing in opposite directions.KMs often refer to completely impacted mandibular molars and usually occur at the third molar.Reports on KMs are few.The etiopathogenesis of this unique event is unknown,but a relation between KMs and mucopolysaccharidoses has been proposed.Several hypotheses that explain this phenomenon have been proposed,but detailed descriptions of related mechanisms are lacking.Moreover,treatment options for KMs,which manifest a unique form of dental impaction,are limited.In this paper,we review the definition,classification,etiology,and pathological mechanism of KMs and its treatment strategy described in the literature to provide a reference for the diagnosis and treatment of this peculiar malocclusion.
