- 1. There was in an apparent sex predilection for male (male to female ratio is 1. 9:1). 2. The peak incidence was in the second and third decades with gradual decline thereafter, and a mean age of 31 years 7 months. 3. The most common site was the mandibular molar-ramus region. 22 cases (68.8%) occurred in the mandible and 10 cases (31.3%) in the maxilla. 4. The largest number of keratocysts were originally diagnosed as primordial cysts (37.5%), followed by dentigerous cysts (18.8%) and residual cysts (9.4%). 5. Radiographs showed various degrees of dental root resorption in 13 out of 25 cases (52%). 6. Maxillary keratocysts tended to exhibit a unilocular type and smooth round border, while mandibular keratocysts had scalloped border. 7. Eleven out of 21 cysts were clinically combined with infection, and 8 cysts showed only bony swelling and 2 cysts were found in the routine radiographic examination. ⓒ 1985 The Japanese Society of Dental Radiology.
