Abstract
We studied 17 clinically diagnosed as “jaw cysts” cases from five years and one month to twelve years and four months.
Because of most cases did not involve pain, they were discovered by obvious facial swelling or during recall. All of the cases were found with swelling of the buccal plates of the bone in the areas of the cysts. Based on the clinical and radiographic findings, it was found that the cysts involved the roots of the primary predecessors and the permanent successors. In the roentgengram, the width of the pericoronal space with the definite lining showed over 3.0 mm. Yellowish fluid was obtained in the cysts in the most of the cases. Pulpotomy was performed on the primary predecessors of six cases and root canal treatment, on three cases. In six other cases, the primary predecessors were affected and non vital. These cysts occurred most frequently in the lower second premolars, and the periapical regions of the primary predecessors and next in the upper anterior teeth regions in five cases. Based on the clinical and histopathological findings, it was thought that the cause of the cysts was that they originated as periapical regions of the primary predecessors. Most of cases were treated by the extraction of the primary teeth and the marsupialization.
The result was that the cysts became smaller and the unerupted successors were successfully arranged in the regular positions.
