Background: The dentigerous cyst is the second most common developmental cysts of the jaws. Despite being asymptomatic in many cases, untreated lesions can reach significant sizes and result in extensive bone resorption. Associated complications may include facial asymmetry, teeth mobility, nerve compression, and pain. Large extensive dentigerous cyst are more difficult to manage.
Aim of the study: This study was conducted to evaluate the management of extensive dentigerous cysts in adults as well as the associated potential risks and complications.
Patients and methods: Fourteen (8 males and 6 females) patients with age range of 20-55 years (mean age of 33.9 years) who had large dentigerous cysts were included in this study. Enucleation of the cystic lesions along with the associated teeth was performed. Patients were clinically and radiographically evaluated for one year postoperatively.
Results: Nine mandibular (64.3%) and 5 maxillary dentigerous cystic lesions (35.7%) were operated. No surgical postoperative complications were encountered. Radiographic evaluation showed adequate new bone formation in the surgical defects within 6-12 months.
Conclusion: Untreated dentigerous cysts can reach a significant size. Extensive dentigerous cysts can be adequately treated with careful enucleation. Extensive dentigerous cysts may be associated with an increased risk for transformation into more aggressive lesions.
