The purpose of this study is to obtain some informations for the differential diagnosis
of ameloblastoma from dentigerous cyst by analysis of the radiographic findings of these
lesions.
The author studied age and sex distribution, the site of the lesion, tooth behavior and
several radiographic features of ameloblastoma and dentigerous cyst. The material
consisted of 65 patients of ameloblastoma and 37 patients of dentigerous cyst.
The results were obtained as followings.
1) The incidence was highest in 2nd decade (29.2%) and total 65 crises consists of 35
males (53.8%) and 30 females (46.2%) in ameloblastoma.62 cases were found in lower
jaw (95.4%) and the highest site of occurence of ameloblastoma was mandibular molar,
region 27 cases. (41.5%)
2) In 65 cases of ameloblastoma, 18 cases were seen in association with tooth and 15
cases (83.2%) out of those were associated with mandibular molar teeth. Mandibular
molar were most frequently involved in dentigerous cyst (11/37 cases,29.7%).
3) (a) 23 cases (35.3%) of tooth resorption were found in ameloblastoma and 11 cases
(29.7%) of tooth resorption were found in dentigerous cyst.
(b) IS cases (23.1%) of tooth migration were found in ameloblastoma and 10 cases
(27.0%) of tooth migration were found in dentigerous cyst.
4) Several radiographic features.
(a) Monolocular type ameloblastoma were seen in 23 cases (35.4) and multilocular type
of ameloblastoma were seen in 42 cases (64.6%). Monolocular type of dentigerous cyst
were seen in 33 cases (89.2%) and multilocular type was seen in 4 cases.
(b) Monolocuiar type ameloblastoma showed 20 cases (87.0%) of scalloped border but
32 cases (97.0%) of dentigerous cyst showed smooth border.
(c) 34 cases (81.0%) of ameloblastoma showed honey-comb appearance, seep-bubble
appearance or mixed appearance. but all 4 cases of dentigerous cyst showed multicystic
appearce
(d) 12 cases (52.2%) of monolocular type ameloblastoma showed slightly increased
radio-pacity in surrounding bone, and 22 cases (66.7%) of monolocular type dentigerous
cyst showed sharp osteosclerotic border. 27 cases (64.3%) of multilocular type
amelo-blastoma and 3 cases (75.0%) of multilocular type dentigerous cyst showed no
changes in surrounding bone.
