Abstract: Jaw cystic lesions present complex challenges involving both teeth and the jawbone，predominantly encompassing jaw cysts and cystic tumors. Jaw cystic lesions often involve healthy teeth in the dentition，and the management of teeth associated with these conditions remains a subject of debate. Particularly，when teeth protrude into the cystic cavity of such lesions，especially if they maintain functional pulp，there are no universally accepted guidelines on whether to preserve the tooth or pulp. This review provides a comprehensive discussion on the etiology，diagnosis，and treatment of jaw cystic lesions. Regarding teeth involved in cysts，a treatment philosophy prioritizing "life > bone > tooth > pulp" is suggested，emphasizing the preservation of teeth with functional requirements to uphold overall oral health. Specific clinical management should be individualized based on the different pathological types of jaw cystic lesions.

摘要： 颌骨囊性病变是一种涉及到牙齿和颌骨的复杂疾病，包括颌骨囊肿及囊性肿瘤。颌骨囊性病变常累及牙列中的健康牙，而与颌骨囊性病变相关的牙齿处理一直备受争议，当受累牙突入颌骨囊性病变囊腔时，特别是有功能的活髓牙，是否保留牙齿或活髓尚无国内外公认的指南。文章综合论述了颌骨囊性病变的病因、诊断和治疗。对于囊肿累及的牙齿，提出了以“生命>骨>牙>牙髓”为治疗理念，强调了保留有功能需求的牙齿以维护口腔整体健康。具体治疗方案应根据不同病理类型的颌骨囊性病变进行个体化制定。
