Decompression of bone cavities associated with dentigerous cysts

Abstract

Objective: The Dentigerous Cyst (DTC) is the most common type of developmental odontogenic cyst and the second most frequent among all that occur in the jaws. It is a benign, radiolucent, usually unilocular lesion, prevalent in males, in the first three decades of life and with a greater occurrence in the mandible. It has slow and asymptomatic growth and its etiopathogenesis is still considered unknown. This paper aims to report two clinical cases of dentigerous cysts, the first in a 50-year-old patient and the second in an 11 year-old patient, both located in the mandible and involving molars. Case report: The method used to treat this lesion was decompression, in which a communication was created between the cyst and the oral cavity, placing a device to condition its drainage and subsequent enucleation ofthe lesion and the tooth involved. This treatment, being less invasive, promotes greater preservation of adjacent healthy stmctures and, consequently, a more favorable postoperative peñod. Conclusion: Therefore, it is of utmost importance that the professional is able to perform this type of procedure and has the knowledge to perform the technique, so that the risk of trans and postoperative complications is reduced.
