Abstract
The purpose of the present study is to offer the fundamental materials for the diagnosis of dentigerous cyst by analysis of the clinical and radiographic findings of these lesions. The subject for this study consisted 118 patients admitted to the Department of Oral Radiology, Kyung Hee University and Seoul National University from 1974 to 1983. Conclusions from this study were as follows: 1. There was a higher incidence in males (70.34%) than in females (29.66%), and the incidence was highest in the second and third decade (26.27%) with the same incidence. (Average age: 25 year) 2. There was a higher incidence in the maxillary teeth (66.10%) than in the mandibular teeth (33.90%) and the maxillary supernumerary tooth (45.76%) was the most frequently involved one. The mandibular third molar (16.10%) was next in order of frequency of involvement followed by maxillary canine (7.63%), mandibular second premolar (5.08%). 3. There was a greater incidence of the central type than the lateral type in the maxilla, while a higher incidence of the lateral type in the mandible. 4. There was a greater incidence of the smooth type (84.26%) than that of the scalloped type (15.74%) and a higher incidence of minor type (70.91%) than the major type (29.09%) in the displacement of associated tooth. 5. Root apices of teeth encompassed or approached by the cysts showed variable resorption in 68.47% of cases.
