The purpose of this study was to obtain information on the clinical and radiographic
features of the dentigerous cysts in the jaws. For this study, the authors examined and
analysed the clinical records and radiographs of 233 patients who had lesions of
dentigerous cyst diagnosed by clinical and radiographic or histopathological examinations.
And the obtained results were as follows:
1. Dentigerous cysts occurred the most frequently in the 2nd decade(38.2%) and
occurred more frequently In males(67.4%) than in females(32.6%).
2. The most common clinical symptom was swelling of the jaw(33.9%), and the
lesions were treated by the method of surgical removal.
3. The type of lesions was mainly observed as central type(72.5%), and size of the
lesion was most frequently observed 2¡­2.9cm in the widest length.
4. The lesions were most frequently observed well-defined outline with hyperostotic
border(49.8%), and smooth margin(73.4%), and homogeneous lesional radiolucency(79.4%).
5. Cortical thinning and expansion of the lesions(82.0%) were observed, and their
direction were most frequently observed toward buccal side(64.0%).
6. The effect old the causative tooth were observed as tooth displacement(41.2%) and
delayed root development(19.3%), an the distance between cemento-enamel junction and
lesional wall attachment of the causative tooth was mainly observed as below 2§®
(79.6%).
7. The effect on the adjacent tooth were observed as loss of lamina aura(66.8%), root
resorption(33.9%), and tooth displacement(31.5%).
8. The effects old the adjacent anatomic structures were observed as displacement of
the mandibular canal(46.5%) and maxillary sinus or nasal cavity(72.2%).
