治疗儿童牙源性囊肿应避免损伤还在发育的牙齿,然而至今对手术方法的选择尚无统一意见。囊肿开窗术和根治性囊肿摘除术均会产生不同的合并症,如恒牙胚死亡、萌出受阻、唇颊侧移位和牙体硬组织矿化不良等。本文的研究目的是对乳牙囊肿采取类似根治术的方法,但又不损伤正在发育的牙胚。材料和方法:从1968年到1983年共治疗222例5～15岁的患有下颌骨乳牙囊肿的儿童。根据临床和X线检查35例为根端囊肿, Treatment of children with dental cysts should avoid damage to the still developing teeth, but so far the choice of surgical methods there is no uniform opinion. Cyst fenestration and radical cyst excision produce different complications, such as permanent tooth germ death, eruption blocked, buccal buccal displacement and dental hard tissue mineralization and so on. The purpose of this study is to perform a radical resection of the primary laryngeal cyst without damaging the developing tooth germ. MATERIALS AND METHODS: From 1968 to 1983 a total of 222 children aged 5 to 15 years with mandibular primary deciduous cyst were treated. According to clinical and X-ray examination of 35 cases of root cysts,
