Radicular cysts originating from primary teeth are considered rare. The study analyzed 49 primary molars with radiolucent lesions ranging from 4-15 mm in diameter. 73.5% of the lesions were diagnosed as radicular cysts, and 26.5% as granulomas. The lesions were more frequent in the mandible. All lesions were associated with severely decayed teeth and only 4 had previous pulp therapy. The present study and the survey of the literature suggest that radicular cysts associated with primary teeth are not rare.
源自乳牙的根端囊肿被认为很罕见。该研究分析了49颗患有直径4 - 15毫米放射性透影病变的乳磨牙。73.5%的病变被诊断为根端囊肿，26.5%为肉芽肿。病变在下颌更为常见。所有病变均与严重龋坏的牙齿相关，只有4颗曾接受过牙髓治疗。本研究及文献调查表明，与乳牙相关的根端囊肿并不罕见。
