  • Dentigerous cyst is the most common type of odontogenic cyst followed by radicular cyst. Most of dentigerous cysts originate from the permanent dentition and a few of them are associated with mesiodens. The complications of a dentigerous cyst associated with mesiodens are eruption abnomalies of adjacent teeth, root resorption, displacement, rotation, diastema and the secondary infection of the cyst due to adjacent teeth. The treatment of a dentigerous cyst of a maxillary mesiodens is to enucleate a cyst with a mesiodens. Otherwise, when it is close to adjacent teeth, a cyst is to reduce the through marsupialization after removing a mesiodens. There are numerous studies on dentigerous cysts and mesiodentes alone; however, the studies on the association of the two are rare. These are case reports about patients with mixed dentition whose dentigerous cyst of a maxillary mesiodens had been removed. After removal, the patients have been regularly checked up and shown satisfactory progress.

  • Dentigerous cysts are the most common type of developmental odontogenic cysts. They form as a result of a separation of the follicle from around the crown of an unerupted tooth. Usually this lesion can be asymptomatic. Such cysts are often discovered accidently on inspection of x-rays. In other advanced cases, cortical bone expansion, displacement of teeth, secondary infection can be observed. The treatment of dentigerous cyst is enucleation. And according to size, location of lesion and environmental structure marsupialization can be considered. However, Marsupialization takes long treatment time and, cystic tissues are remained so secondary surgery may be needed for total removal., Risks of oroantral fistula, damage on maxillary sinus wall and infraorbital nerve can be considered as complications of conventional surgical treatment of cysts located in maxillary sinus. We treated third molar origin dentogerous cyst located in maxillary sinus removing endoscopically both the tooth and an associated dentigerous cyst. We report our clinical experience with literature review.

  • Odontoma is an asymptomatic slow-growing odontogenic tumor. It is usually found by chance in the maxilla or mandible on radiography, or when it deforms the adjacent teeth. It is commonly found in patients who are 30 years of age or younger. We report our encounter with an odontoma within a dentigerous cyst found incidentally in a 56-year-old man. He presented with abnormal fullness in the right infraorbital area of the cheek. During the evaluation of the mass, we incidentally detected the odontogenic tumor within a dentigerous cyst in the patient's maxilla. Under general anesthesia, complete surgical drainage of the infraorbital cystic mass was performed. Enucleation of the odontogenic tumor and a bone grafting from the iliac bone were also performed. The final diagnosis was odontoma. After 2 years of follow-up, there was no sign of recurrence of the tumor. In case of odontogenic tumors, even in old patients, it is important to suspect an odontoma. When odontoma accompanies a dentigerous cyst, surgical excisional biopsy should be performed to rule out malignancy. In case of a large bony defect after enucleation, autogenous bone grafting is essential for reconstruction.

  • Purpose: Dentigerous cyst is the most common intra-osseous lesion of the jaw. Dentigerous cysts can cause delays in eruption of the affected permanent tooth in mixed dentition. It has been suggested that the affected permanent tooth could be erupted spontaneously after the dentigerous cyst was enucleated. But in some cases, orthodontic treatment or autotransplantation technique is known to be required. This study reviews previously performed prognoses of affected permanent teeth, which will lead to a more efficient treatment plan. Patients and Methods: With 28 patients who have undergone cyst enucleation and 10 patients who have undergone autotransplantation, the prognosis of permanent teeth was observed. Results: After cyst enucleation, spontaneous eruption of a permanent tooth was observed in 56.3% patients, orthodontic treatment was performed in 25% patients. The success rate of autotransplantation was 60.0%. Discussion: The first choice for treatment of dentigerous cyst in mixed dentition is to guide spontaneous eruption of permanent teeth. For cases without enough eruption space, the orthodontic treatment should be considered. Autotransplantation should be considered when the spontaneous eruption is not expected. It should be considered that the rate of successful autotransplantation is decreased on maxilla anterior area.

  • Dentigerous cyst is an odontogenic cyst which occurs in unerupted tooth crown. After the crown formation, enamel epithelium remnants surrounded continuously proliferates and it forms effusionfluid cyst and expands due to increased internal osmotic pressure. Treatments of cysts are mainly enucleation, marsupialization and de-compression. When deciding the way of treatment, the age of a patient, the anatomical circumstances, the region of lesion and the size of cyst should be considered. Marsupialization is that some parts of internal cystic wall would be converted into oral mucosa if the cyst is large size and is concerned about neighboring anatomic structure. It can be accompanied by enucleation later and eruption of related tooth can be possible. If there is a limitation of spontaneous tooth eruption, eruption of tooth can be induced by orthodontic apparatus. There were 3 patients had dentigerous cyst and underwent marsupialization, their impacted teeth had preserved and had induced eruption, all showing satisfactory results.

  • Oral and maxillofacial cyst is defined as an pathogenic cavity with an lining epithelium and connective tissue wall. Cysts of the jaws and periapical regions vary in histogenesis, treatment and prognosis. Cysts with similar clinical and radiographic can be shown different histopathologic features. Cysts are classified into odontogenic cysts and nonodontogenic cysts. Cysts are also divied into true cysts and pseudocyst. True cysts are lined with an epithelium, however pseudocysts are not lined with epithelium. A periapical cyst, dentigerous cyst and odontogenic keratocyst is clinically common and important lesions at dental clinic.

  • The purpose of this study is to find the histopathological pattern of cysts. We reviewed the hospital chart, out-patient chart, roentgenogram, histopathologic report and operation report of 152 patients who had been diagnosed as cyst and treated at the department of Oral and Maxillofacial Surgery of Korea university hospital between Jan. 1, 1995 and Dec. 31, 1998. And then we studied clinically with regard to pathological classification, age and sex distribution, anatomical distribution and so on. The results were as follows : 1. In pathologic classification, radicular cyst (97cases, 64%), dentigerous cyst (35cases, 23%), odontogenic keratocyst (8cases, 5.3%) were dominant among cases of cyst. 2. The pattern of age distribution in cases of radicular cyst, dentigerous cyst and odontogenic keratocyst was similar to that found in previous studies. The peak incidence was in the second decade (27%) and third decade (29%) in overall cases. 3. The male-to-female ratio was 1.9 : 1. 4. Radicular cyst occured most frequently in the maxillary incisor teeth area, dentigerous cyst in mandibular wisdom teeth area, and odontogenic keratocyst in mandibular molar area.

  • The dentigerous cyst originates through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium or between this epithelium and the tooth crown. It is always associated with unerupted teeth. There are two methods of treament which are generally accepted. One is the enucleation of the cystic sac in its entirety, the other is the Partch operation, or the marsupialization, by which the cyst is uncovered or "deroofed" and the cystic lining made continuous with the oral avity or surrounding structures. The present case report showed that in instance of dentigerous cyst & odontogenic keratocyst surgical enucleation followed by careful excision of all cyst wall was successfully carried out and recovery and healing were rapid and uncomplicated.

  • The dentigerous cyst originates through alteration of the reduced enamel epithelium after the crown of the tooth has been completely formed, with accumulation of fluid between the reduced enamel epithelium and the tooth crown. The dentigerous or follicular cyst comprises about 20% of all dental cysts. It usually occurs between 20 and 30 years of age but is occasionally seen in children or in old people. The most common sites of this cyst are the mandibular third molar and maxillary cuspid areas, since these are the most commonly impacted teeth. Many of these cysts give no clinical symptoms until noticeable asymmetry of the face develops. Rarely it develops to an ameloblastoma, epidermoid carcinoma and mucoepidermoid carcinoma, so early removal leads to better result. Roentgenographic examination of the jaw involved by a dentigerous cyst will reveal a radiolucent area. Recently the authors have experienced a giant dentigerous cyst which produced the bony deformity of the maxillary and hard palate bone. The cyst was completely removed under the local anesthesia by Caldwell-Luc approach.
