Among 25 AMs, 44.0% were of desmoplastic type, with honey-combed appearance. 84.0% of AMs were circular or oval in shape, 84.0% expanded buccally, and 36.0% invade the nasal floor. Among 89 OKCs of 88 patients, 61.8% were circular or oval, 58.4% expanded buccally, 49.4% were dentigerous, 41.6% nearly filled the maxillary sinus, and 13.5% invaded the nasal floor. 93.7% (74\/79) of DCs enveloped a single tooth, and the tooth\u2013cyst relationship was centripetal in 35, eccentric in 30, and circumferential in 9. Moreover, 98.2% (55\/56) of the cysts enveloping a supernumerary tooth were DCs, while 80.9% (38\/47) of the cysts enveloping the third molar were OKCs. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> Maxillary AMs tend to grow with buccal expansion and invade the nasal floor, and DAs with honey-combed lobularity are common. Maxillary OKCs have variant shapes and tend to invaginate the maxillary sinus. The tooth\u2013cyst relationship of dentigerous OKCs and DCs can be centripetal, eccentric, or circumferential. <\/jats:p><\/jats:sec>","DOI":"10.1259\/dmfr.20190066","type":"journal-article","created":{"date-parts":[[2019,5,24]],"date-time":"2019-05-24T12:54:05Z","timestamp":1558702445000},"page":"20190066","source":"Crossref","is-referenced-by-count":22,"title":["Three-dimensional radiographic features of ameloblastoma and cystic lesions in the maxilla"],"prefix":"10.1093","volume":"48","author":[{"given":"Yuan","family":"Meng","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology, Peking University School and Hospital of Stomatology &amp;
