Fifty-two cases of traumatic bone cysts in 50 patients were analysed clinically and
radiologically.
The obtained results were as follows ;
1. Women showed a slightly higher incidence than did men (56% of patients) and the
average age proved to be 18.6 years.
2. The majority of the cases were asymptomatic, being detected incidentally, and over
the half of the cases occurred in the mandibular symphyseal region.
3. All cases were unilocular and the largest diameter of the lesions varied from 1 to
10 §¯, mean 3cm.
4. Some degree of marginal condensation was present in 28 cases and 23 cases
presented pencil-sketch appearance.
5. Many anatomical cortical plates (especially, mandibular inferior cortex and lamina
durae) consisted of the margin of the lesions partly.
6. Erosive change of the mandibular inferior cortex was caused by 12 cysts, but
cortical expansion only by 3 cysts including 8 cases of buccal expansion.
7. The lesion enveloped the roots of the adjacent teeth in 27 cases and scalloping was
present between roots in 17 cases.
8. Lamina durn of the teeth was destroyed by only 1 cyst and in 1 case root
resorption was noticed. But there was no divergence of the roots of teeth.
