Objective:
The purpose of this study was to assess the morbidity and outcomes associated with large cysts that developed in conjunction with pulpotomized deciduous molars.
Study Design:
This retrospective study was based on the files of 18 patients who were referred to 2 oral surgery departments during a 10-year period (1986-1996). The inclusion criteria were large cyst lesions (>1 cm in diameter) and complete documentation. Data regarding symptoms at presentation, histologic and radiologic features, treatment modalities, morbidity, and outcomes were analyzed.
Results:
An equal gender distribution of patients was found, as were a later development in males (12+/-2 years in boys, 9+/-2 years in girls) and a 5:1 ratio favoring the mandible over the maxilla. Treatment included enucleation (12 patients) and marsupialization (6 patients). The morbidity was high and included loss of permanent teeth (3 patients), extensive loss of alveolar bone (3 patients), use of flaps (2 patients), and adjuvant orthodontic treatment (9 patients).
Conclusion:
Failure of early detection and treatment of cysts that develop in conjunction with pulpotomized deciduous molars can cause considerable morbidity. Therefore, periodic clinical and radiologic follow-up until the eruption of succedaneous teeth is recommended.
