    Dentigerous cyst with an impacted canine: Case report
    (2011) Agacayak K.S.; Kose I.; Gunes N.; Bahsi E.; Yaman F.; Atilgan S.
    Dentigerous cysts are the second most common developmental odontogenic cysts after radicular cyst. They usually present in the second or third decades of life and these cysts are rarely seen during child hood. Their frequency in the general population has been estimated at 1.44 cysts for every 100 unerupted teeth. According to frequency of impaction, the maxillary permanent canine ranks second only to the third molar, with a prevalence of approximately 2% in the general population. Impacted canines are positioned palatally 85% of the time. The frequency of impaction is three times greater in females than males. In many instances the cyst may be asymptomatic till it attains a large size. It usually presents as a slowly enlarging, sometimes painful swelling; particularly if infected. At radiography, dentigerous cysts appear as well-defined, round or ovoid, corticated, lucent lesions around the crowns of unerupted teeth. The radiographic appearance of such dentigerous cysts is comparable with that of cystic, unilocular odontogenic keratocysts. Treatment includes extraction of the associated tooth and enucleation of the cyst. In this study we present dentigerous cyst that caused by impacted canine.

    Interesting case: An unusual location for a large pleomorphic adenoma arising in the maxilla
    (2010) Tanrikulu R.; Yaman F.; Atilgan S.; Gunes N.; Gorgun B.
    Pleomorphic adenoma is the most common benign tumor of the major salivary glands, especially of the parotid gland. It is much less common in the minor salivary glands of the oral cavity, and it rarely occurs in others sites in the head and neck (intraosseous, lacrimal gland, chest). A 51-year-old woman was referred to our department complaining of painless swelling of the left maxillary vestibular sulcus, which had been felt pain with the pressure. CT scan revealed a well defined expansile mass arising from pterygoid plates, infratemporal space to palatinal bone and arcus zygoma. Transoral biopsy specimen showed pleomorphic adenoma. Patient was treated by surgical excision. Follow up goes on in postoperative period. Our study's aim is to present the pleomorophic adenoma's case which is extended up large propotion in an unusual location. Our case is evaluated by in terms of diagnose and treatment result. Furthermore in the light of literature reviews we discuss the pleomorphic adenoma's incidence, location, and recurrence rates. We believe that our presentation is very interesting in point of view rare location and expansive mass.
