Conservation of permanent teeth involved in dentigerous cysts in mixed dentition: a series of cases

Abstract

Purpose: To evaluate the effectiveness of marsupialization or decompression of dentigerous cysts involving the crowns of unerupted permanent teeth during the state of mixed dentition with observation of outcomes. Patients and methods: Six patients were included in this series. Two were females while the rest were males. They were operated under local anaesthesia except one who was operated under general anaesthesia. Results: All involved teeth erupted spontaneously without the need for orthodontic intervention in all but one patient, who required subsequent intervention. No adverse outcomes were recorded in our series. Clinical relevanceScientific rationale for study Children in mixed dentition age group with dentigerous cysts involving the crowns of unerupted permanent teeth are either managed radically via enucleation of the lesion with removal of the related permanent tooth/teeth, or can be managed conservatively via marsupialization of the cyst and decompression which allows the teeth to erupt with minimum problems. Principal findingsMarsupialization allows eruption of the teeth with minimum intervention and without the possible problems associated with radical treatment. Practical implicationsMarsupialization is relatively simple manoeuvre that can be done in the office in most of the cases with good results.
