1 性别与年龄:1981～1986年我科收治牙源性颌骨囊肿110例,其中滤泡囊肿61例,男52例,女9例;根尖囊肿49例,男22例,女27例。年龄6～69岁。病史最短10天,最长20年。发病高峰年龄:滤泡囊肿为10～19岁,根尖囊肿为50～59岁。 2 发病部位:滤泡囊肿上颌42例,下颌19例。最常见的发病部位是上颌前牙区,可能是该区多生牙发病率高,而多生牙牙胚容易在发育期变性形成囊肿,本组由此引起者即达30例;其次为下颌角、升支部,多由下颌第三磨牙牙胚变性所引起计12例。在本组滤泡囊肿中,含牙囊肿52例,始基囊肿(包含角化囊肿)7例,复发性囊肿2例。根尖囊肿
1 gender and age: 1981 to 1986, our department admitted 110 cases of odontogenic jaw cysts, including follicular cyst in 61 cases, 52 males and 9 females; 49 apical cysts, 22 males and 27 females. Age 6 to 69 years old. The shortest history of 10 days, up to 20 years. Peak age of onset: follicular cyst is 10 to 19 years old, apical cyst is 50 to 59 years old. 2 incidence sites: follicular cyst in 42 cases of maxillary, mandibular 19 cases. The most common site of incidence is the maxillary anterior region, which may be the incidence of multiple teeth in this area is high, and multiple tooth germs tend to degenerate during development to form cysts, the group caused by up to 30 cases; followed by the mandibular angle , Ascending branch, mostly caused by the mandibular third molar densification caused by 12 cases. Follicular cysts in this group, containing 52 cases of dental cysts, primordial cysts (including keratocysts) in 7 cases, 2 cases of recurrent cysts. Apical cyst
