造釉细胞瘤为颌骨中心性上皮肿瘤,在牙源性肿瘤中较为常见。一般多发生于成年人,男女发病无明显差别,多发生于下颌骨。关于造釉细胞瘤的组织来源,尚有不同的看法:大多数认为由釉质器或牙板上皮发生而来;但也有认为系由牙周膜内上皮残余或由口腔粘膜基底细胞发生而来;亦有谓由始基或含牙囊肿等转变而来。发生于颌骨以外的造釉细胞瘤可能由于口腔粘膜基底细胞或上皮异位发展而成。如发展较快,可能恶变为肉瘤。多发生于青壮年,以下颌骨体部及下颌角为常见。上颌骨的造釉细胞瘤很少 Ameloblastoma is a mandibular central epithelial tumor that is more common in odontogenic tumors. Generally occurs in adults, no significant difference between men and women, occurred in the mandible. On the origin of ameloblastoma tissue, there are different views: Most think that the enamel or dental board epithelial occurred; but it is also believed that by the periodontal epithelial remnants or oral mucosal basal cells from; There are also known from the base or containing dental cysts and other changes from. Amebroglioma occurring outside of the maxilla may develop as a result of ectopic development of oral mucosal basal cells or epithelium. If developed rapidly, may become malignant sarcoma. Occurred in young adults, the following mandibular body and mandibular angle are common. There are few ameloblastomas in the maxilla
