Association of Dentigerous Cyst with Impacted Third Molar


The crown of an impacted or unerupted tooth might produce an odontogenic cyst called a dentigerous cyst. Such a cyst is initially asymptomatic unless infected and can only be found by normal radiography evaluation. The main complaint of a 20-year-old female patient who visited our clinic was edema on the bottom left side of her face, which had been there for three months. On percussion, the first and second molars showed a little sensitivity, and the second molar on the left showed grade II mobility. A dentigerous cyst should always be distinguished radiographically from a typical dental follicle. The most frequent cysts with this radiological appearance are dentigerous cysts. On radiographs, the cyst usually appears unilocular with well-defined margins and borders that are frequently sclerotic, but it can occasionally appear multilocular and have a continuous cystic membrane.
