ABSTRACT:
Background: Dentigerous cysts are the most common developmental odontogenic cysts of the jaws and account for approximately 20-24% of the jaw cysts. They mostly surround the crown of unerupted teeth, odontomas or supernumerary teeth. The treatment modalities range from marsupialization to enucleation of the lesion. Materials and methods: A prospective study was done in patients reporting to the department of oral & maxillofacial surgery from June 2012 to December 2013. During the specified period, 14 cases of dentigerous cyst were treated by enucleation and marsupialization. Results: From June 2012 to December 2013, 14 cases of dentigerous cysts were diagnosed. The mean age of occurrence of dentigerous cyst was 23.35 years. Out of 14 cases 5 (35.71%) were females, and 9 (64.29%) were males. The most common site for DC was the mandibular molar region. Conclusion: The most frequent involved site was the posterior region of the mandible and the most commonly associated tooth was the third molar tooth. The cysts had a tendency to displace associated and/or adjacent teeth. Enucleation and marsupialization were successful treatment modalities with no recurrence seen in any of the patients.
Keywords: Dentigerous cyst, impacted tooth, enucleation.
INTRODUCTION
A dentigerous cyst is one that encloses the crown of an unerupted tooth by expansion of its follicle, and is attached to its neck.1 It is the second most common odontogenic cyst after radicular cysts, accounting for approximately 24% of all true cysts in the jaws.2 They are usually associated with impacted teeth. In some instances they may be associated with supernumerary teeth and odontomas.3 Dentigerous cysts are often discovered incidentally when radiographs are taken to investigate a failure of tooth to erupt, a missing tooth or mal-alignment.
MATERIALS AND METHODS:
This study was conducted from June 2012 to December 2013 in Department of Oral & Maxillofacial Surgery at Government College of Dentistry, Indore (M.P). A total of 14 cases of dentigerous cyst treated with enucleation or marsupialization during this period were analyzed for age at diagnosis, gender, lesion location, presenting symptoms and treatment outcomes. A pre-operative CT scan/orthopantomogram was done for all patients to determine the extent of the lesion. Enucleation was done in 11 cases and marsupialization in 3 patients. The diagnosis was confirmed with histological analysis of the...
