함치성 낭종은 치근단 낭 다음으로 가장 흔한 치원성 낭종으로 치관완성 후, 미맹출된 치아의 법랑질과 퇴축 법랑 상피 사이에 액체가 축적되어 발생한다. 함치성 낭종의 약 95%는 영구 치열에서 발생하지만, 과잉치와 연관된 함치성 낭종은 그 발생이 드물어, 전체 함치성 낭종 중 5-6%를 차지한다. 이러한 함치성 낭종은 호발 연령이나 성별의 관점에서 보면, 일반적인 함치성 낭종과 비슷한 특징을 가진다. 과잉치와 연관된 함치성 낭종의 대부분이 상악 정중 과잉치와 관련하여 발생하는 것으로 알려져 있다. 상악 정중 과잉치에서 발생한 함치성 낭종의 합병증은 상악 정중 과잉치의 합병증과 유사한데, 인접 영구치의 맹출 장애, 치근 흡수, 전위, 회전과 정중이개, 인접 치아에 의한 낭종의 이차적 감염 등이 있다. 상악 정중 과잉치에서 발생한 함치성 낭종의 치료법으로는 과잉치와 과잉치를 둘러싼 낭종을 함께 적출하는 방법과 낭종이 정상 치아와 근접한 경우, 과잉치를 제거한 뒤, 조대술을 통해 낭종의 크기를 감소시킨 후 제거하는 방법이 있다. 과잉치와 낭종 적출 후, 변위된 인접 치아의 자발적 맹출 및 맹출 경로 변화가 관찰되기도 하나, 만약 그렇지 못한 경우에는 변위된 치아의 교정적 견인 및 부가적인 교정적 처치가 필요하다. 함치성 낭종과 과잉치 각각에 관한 연구는 많이 행해졌으나, 이 두 발육 장애가 연관된 증례에 대한 보고는 상대적으로 드물다. 본 증례에서는 유치열기와 초기 혼합 치열기 아동에서 상악 정중 과잉치에 함치성 낭종이 관찰되어 과잉치와 낭종의 제거 후, 정기적 검진시 비교적 양호한 결과가 관찰되었기에 이를 보고하는 바이다.

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.

여포성 치아낭종은 치아여포와 관련되어 발생하는 낭종으로서, 매몰 혹은 미립치아의 치관부가 완전히 형성된 이후에 치관부와 퇴행성 변화를 일으킨 사기질 상피 사이에 액체가 저류되어 낭종으로 발달된 것을 말한다. 여포성 치아 낭종은 전 치성낭종의 약 20%를 차지하며, 영구치에서 잘 생긴다. 하악골에 주로 발생하며, 특히 매몰치아가 흔한 하악골색 제 3 대구치, 상악골의 견치에서 잘 볼 수가 있다. 안면부 기형이 나타날 때까지는 임상증세가 없는 것이 보통이나 종들이 커지면 안면부 기형과 함께 구개부 융기, 종물부위의 이물감, 암통 및 인접치아의 치근 흡수등을 초래하기도 한다. 드물게는 범람종, 상피암 및 점막상피암등의 합병증을 일으킬 수 있으므로 조기적출을 하는 것이 좋다. 진단방법으로는 X-선 촬영이 중요하며 이때에 치관주변부가 투명하게 나타난다. 저자들은 최근 안면부 기형 및 경구개 융기를 초래한 거대 여포성 치아남종이 있던 15세 남자 환자를 치험하였기에 문헌적 고찰과 함께 보고하는 바이다.
