The author studied the age distribution, etiology, affected site and several radiographic
features of periapical granulomas, cysts, and abscesses.
The material consisted of 928 films obtained from the patients who were diagnosed
and treated under the diagnosis of periapical granulomas, cysts, and abscesses during
the past 8 years (1979-1986) at the Infirmary of Dental School, Chosen University.
The obtained results were as follows '
1. The order of incidence was as follows: periapical abscess (67.2%), granuloma, and
cyst.
2. The age distribution revealed the highest incidence around the age of 30 and
relatively higher incidence over the age of 60 in the case of periapical abscess and
granuloma.
3. In the frequency of location:
Periapical abscesses occured most frequently in the mandibular molars, Granulomas
showed relatively higher incidence in maxilla than in mandible. Cysts were most
common in the maxillary anterior teeth.
4. The mean diameter of dental granuloma was 5.9 §®, however, all dental granulomas
were less than 9.3mm in diameter. The mean diameter of periapical cyst was 13.8mm.
5. Periapical cyst revealed well circumscribed radiolucent lesions and 77.8% of the
lesion showed white line. 86.0% of dental granuloma showed well circumscribed border,
54.5% sclerosis on surrounding bone and 38.5% partial white line. Periapical abscess
revealed diffuse radio-lucent lesion, 89.6% of the lesions had sclerosis on surrounding
bone, and 38.0% sinus tract.
