A dentigerous cyst is an epithelium-lined sac that surrounds the crown of an impacted, embedded, or unerupted tooth. Many surgical procedures have been described for the elimination of dentigerous cyst, but they can be devided into two basic group: enucleation and marsupialization. Marsupialization is a conservative technique which allows the reduction or elimination of a cystic lesion by making it an accessory compartment to the oral cavity and it is the best way to conserve a tooth affected by dentigerous cyst and to permit its eruption, especially in young patient. After using marsupialization to treat dentigerous cyst associated with the crown of unerupted premolar in young patient, the results were as follows: 1. Reduction of bony expansion and rapid bone regeneration without infection and recurrence were observed. 2. Normally spontaneous eruption of involved teeth were permitted, as well as loss of affected tooth was avoided. 3. Follow-up examinations revealed no complication and recurrence.

Marsupialization is widely used as a primary treatment modality for reducing size of large cysts. However, there is no recommendation for specific duration of marsupialization. In addition, Carnoy's solution usually is applied at the time of enucleation as a fixative agent. In this report, we present an appropriate marsupialization duration of ameloblastoma involving two unerupted teeth. In this present study, marsupialization using a Foley catheter was performed in two cases of ameloblastoma of the mandible involving two adjacent impacted teeth. Carnoy's solution was applied for 3-5 minutes after enucleation in both patients. Periodically during marsupialization, the size of the radiolucency was measured in panoramic view, and clinical examination was performed. No remarkable paresthesia or soft tissue injury was observed after application of Carnoy's solution or during follow-up. We recommend 12 to 16 weeks as an adequate marsupialization duration for a large ameloblastoma involving two impacted teeth based on increased radiopacity along the margins of the lesions. Poor oral hygiene was an issue after 12 weeks of marsupialization in one case. There were no remarkable complications with Carnoy's solution in either case. The Foley tube has a two-way system that is more effective for irrigating the cavity than is the conventional one-way system.

Cyst is a closed sac, having a distinct membrane and division compared to the nearby tissue. Most cysts in the oro-maxillofacial area are odontogenic origin and found most commonly by oral and maxillofacial surgeons. Enucleation is considered as a definitive therapy in the management of these cysts. However, to select the treatment method for large cyst, consideration of position of the cyst, size and accessibility to main structure are needed. Marsupialization is a minimal invasive technique to treat large odontogenic cyst and tumor without damage to adjacent important structures. This study was undertaken to describe three cases of odontogenic cysts and tumors of jaws that were successfully treated with enucleation after marsupialization.

The purpose of this study was to evaluate the eruption patterns of mandibular premolars associated with dentigerous cysts after marsupialization regarding the depth, angulation and root development of impacted teeth. Spontaneous eruption was found in 93% of mandibular premolars after marsupialization. Eruption speed and rate of angulation change were greater in mandibular premolars associated with a cyst than those on the non-cyst side. The group with less matured roots tended to have greater eruption speed and angulation change. The eruption speed and angulation change declined rapidly during the first 6 months after marsupialization. Based on the results of this study, it might be possible to predict the eruption pattern of mandibular premolars associated with a cyst after marsupialization, which would be useful for treatment planning.

Dentigerous cyst is a cyst arising by a seperation of follicles from around the anatomical crown of an unerupted tooth within the jaws. The dentigerous cyst is seen during routine radiographic examination. It is detected radiographically as a sharply delineated, round or oval, unilocular, homogeneous, and radiolucent area within which there is the crown of an unerupted tooth. The histological appearance of the dentigerous cyst is usually attached to the tooth at the cementoenamel junction and the sac lined by a thin, regular. stratified squamous epithelium. The dentigerous cyst can be treated by two surgical procedures: enucleation or marsupialization. The size and location of the lesion usually dictates the surgical procedures. The marsupialization consists of the removal of only a portion of the wall of the cyst to make the remaining cystic lining continous with the oral mucosa. The cyst, deprived of its supporting hydrostatic pressure, gradually shrinks until it is obliterated. The marsupialization is the best way to conserve the tooth affected by a dentigerous cyst and to permit its eruption. especially in a young person. Main advantages of the marsupialization are its relative simplicity and its conservation with respect to adjacent important structures. In marsupialization technique, a plugger can be constructed, if necessary, to maintain the opening and prevent food debris from entering the cystic cavity. However, the disadvantage is the potentiality of leaving pathologic tissues. Therefore frequent recall appointments are advisable.

Objective: The purpose of this study was to determine whether cyst enucleation would be done after marsupialization of large cystic lesion on the jaws or not, and if so, when it should be done. Patients & Methods: 12 patients with cystic lesion treated by marsupialization only and 10 patients with cystic lesion treated by marsupialization followed by enucleation were examined in this study. Postoperative clinical and radiographic examinations were performed at 1, 4, 7, 10, 13, 16, 19 months on 22 patients. Bone regeneration and reduction rate of the residual cystic cavities and bone density were evaluated with a analysis of digital panoramic radiographs. Also histological evaluation of the healing process was performed on 1 patient. Results: Uneventful healing and spontaneous bony filling of the residual cavities were observed in all cases. Postoperative radiographs showed that the size of the lesions was reduced for a few months, but the reduction rate of the residual cavity was minimized for 13~16 months after marsupialization. The bone density was increased 22.5 % after 19 months. Conclusion: This results suggest that the appropriate timing to perform enucleation would be 13~16 months after marsupialization. The state of healing process could be confirmed by histological examination and radiographic evaluation of bone density. Enucleation after marsupialization could be applied appropriately to reduce the periods of bone healing in large cystic lesion on the jaws.

Ameloblastoma is a benign neoplasm originating from odontogenic epithelium. It is the most common neoplasm in the jaws and is characterized by aggressive behavior and local invasion. Unicystic ameloblastoma (UA) has a unilocular feature in radiologic examination and a cystic feature histologically. Decompression and marsupialization are conservative method of treatment of large UA. The purpose of decompression and marsupialization are size reduction of the mass, which makes it easy to handle at total enucleation with protection of nerve damage and facial deformity. Here we report successful conservative treatment of extensive UA using decompression and marsupialization with a review of literatures.

Ameloblastoma is the most frequently accuring odontogenic tumor in mouth. The biologic behavior of this neoplasm is locally invasive tumor with a high rate of recurrence. But in case of unicystic ameloblastoma, it was known that the neoplasm can be treated by marsupialization and the recurrence rate is lower. In our clinic, we tried to treat one of ameloblastoma cases by marsupialization and finished the treatment by enucleation via intra-oral approach with sagittal ramus osteotomy. This is a report of that case about 29 years old female patient.

Odontogenic keratocysts (OKCs) are one of the most aggressive cysts in the oral and maxillofacial area because of their high recurrence rate and infiltrative behavior. In growing patients with OKCs, a radical treatment approach might cause numerous complications, including the disturbance of jaw growth and loss of the involved tooth. This case report describes successful comprehensive orthodontic treatment combined with marsupialization of the cyst in a young girl who exhibited an OKC with impacted teeth. The 10-year-old girl presented with an OKC extending from the mandibular symphysis through the left mandibular body, with ectopic impaction of the mandibular left canine and first premolar, as well as congenitally missing bilateral mandibular second premolars. Interestingly, spontaneous improvement of the positions of the ectopic impacted teeth, along with a reduction in the size of the cyst, occurred during marsupialization. The sequential use of removable and fixed appliances enabled orthodontic traction of the impacted teeth. The treatment outcome was stable at 2.5 years after the end of the treatment. We speculate that comprehensive orthodontic treatment combined with marsupialization can be an effective treatment strategy for patients with OKCs, especially when they are encountered in young, growing patients with impacted teeth.

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.
