Dentigerous cyst is the most commonly occurring odontogenic cyst after radicular cyst and accounts for 15% of all true cysts in the jaws. The cyst is more common in mandible than in maxilla. The dentigerous cyst is commonly associated with impacted mandibular third molars. In maxilla, the incidence is rare. Dentigerous cyst in maxillary sinus in association with an impacted third molar is an uncommon entity. We present a case of dentigerous cyst associated with an impacted third molar, completely obliterating the maxillary sinus in a 28-year-old female.
含牙囊肿是继根尖囊肿之后最常见的牙源性囊肿,占颌骨所有真性囊肿的15%。该囊肿在下颌比在上颌更常见。含牙囊肿常与下颌阻生第三磨牙相关。在上颌,其发病率较低。上颌窦含牙囊肿合并阻生第三磨牙是一种罕见情况。我们报告一例28岁女性患者,其含牙囊肿合并阻生第三磨牙,完全阻塞了上颌窦。
