Background:  Juvenile paradental cysts typically occur on the buccal aspect of mandibular first and second molars in children aged 6 to 11 years. The cysts may be treated by enucleation, with or without extraction of the involved teeth, or by marsupialization. This report demonstrates the success of a conservative surgical technique (marsupialization) and good outcomes in five juvenile paradental cyst cases.

Methods:  Five patients (two males, three females) with a mean age of 8.4 years, complaining of mandibular buccal swelling around the molars, underwent marsupialization of radiolucent lesions involving partially or fully erupted permanent first molars. Clinical, radiographic and histological characteristics led to diagnoses of juvenile paradental cysts.

Results:  The surgical procedures were simple to perform and resulted in complete remission of the lesions with no complications. The mean follow-up time was 2.8 years. No recurrences were observed, the related teeth developed normally, and complete periodontal healing was achieved.

Conclusions:  The surgical marsupialization of juvenile paradental cysts achieved good outcomes without compromising the development of related teeth, and thus may be considered an appropriate treatment for paediatric patients.
