The Dentigerous cyst is reported to be one of the most common lesions of the jaw. It is derived from reduced enamel epithelium that surrounds the crown of an unerupted tooth. Dentigerous cysts usually remains asymptomatic and presents as well-circumscribed radiolucencies surrounding the crown of a tooth. Most dentigerous cysts are treated by surgical enucleation or marsupialization of the cyst to allow eruption of the permanent tooth. The nasopalatine duct cysts derived from the islands of epithelium remaining after closure of the embryonic nasopalatine duct. The cyst presents as a well-circumscribed oval or heart-shaped radiolucency located in the midline of the anterior maxilla between the roots of the central incisors. Treatment is by surgical enucleation, employing a palatal approach. This report present two cases. One case was diagnosed with dentigerous cyst and treated by enucleation. 12 Months later, affected second premolar was erupted normally. The other case was diagnosed with nasopalation duct cyst. Histological examination of the enucleated cyst confirmed a nasopalatine duct cyst. There was no recurrence during follow up period.

Cyst is a cavity filled with fluids and semi-fluids that is lined with epithelial cells. Odontogenic cysts are those that form within the jaw which origin from dental follicles, enamel epithelium remnants of the crown, Malassez epithelial cell rest and basal cell layer of the oral epithelium. In such cases, treatment methods such as enucleation, marsupialization, decompression, surgical excision etc. can be used according to the lesion's characteristics, size, relationship with the surrounding tissue, patient's age and developmental status. This case was to report an odontogenic cyst caused by an impacted immature permannent tooth and its treatment. The cyst was removed by decompression. Cystic cavity was healed with bone tissue and the impacted permanent tooth erupted without any recurred cystic lesion.

Most dentigerous cysts are solitary. Bilateral and multiple dentigerous cysts are rare and occur typically in association with a number of syndromes such as Maroteaux-Lamy syndrome, Hunter's syndrome, Basal cell nevus syndrome, Marfan syndrome, cleidocranial dysplasia. The presented case is of bilateral nonsyndromic, dentigerous cysts associated with mandibular right and left first premolars. A marsupialization procedure may be a choice of treatment for a large sized dentigerous cyst rather than an enucleation. The marsupialization procedure is recommended during the age when the erupting force of the teeth is still strong. We can expect the unerupted tooth to erupt normally. Although most of bilateral or multiple dentigerous cysts which are not associated with syndromes are rare, a bilateral dentigerous cyst without syndrome is seen. Therefore, it is wise to explain a possibility of development of new one to patient / parents in advance.

A cyst that develops in children's jaw occasionally disturbs the eruption of the succedaneous teeth. These teeth, however, usually have the potential of eruption. So, if the obstacles to eruption are eliminated, it is possible that the teeth erupt spontaneously to their normal position. In those cases, it usually requires the management of the cyst and the eruption guidance of the displaced teeth. Many surgical procedures have been described for the elimination of cysts. When the cyst is large and displaces the permanent teeth, marsupializaion is a surgical technique that may be preferred to enucleation in treatment of cysts. In marsupializaion, if the opening is maintained properly, it may be possible to manage the cyst and guide the displaced teeth into the normal position. In these cases, the cysts were managed with marsupialization in concomittent application of acrylic obturators, and as a result the displaced permanent teeth were guided into normal position. Even though the etiologic factors of the two cases are different, the treatment was the same. And both cases show that the potential for heal ing is remarkable with spontaneous relocation of displaced tooth, provided the opening is maintained during the eruption of the permanent tooth.

Dentigerous cyst is a cyst arising by tissue fluid accumulation between the enamel and the residual enamel epithelium. It includes the crown of the impacted tooth and excludes the root. The treatments of the dentigerous cyst are enucleation, marsupialization, decompression, surgical excision and etc. In these cases children were evaluated for the chief complaints of the remained mandibular primary second molar. Each cases showed swelling on the buccal side of the primary secondary premolar. In the radiologic evaluation a radiolucent lesion including the crown of the mandibular secondary premolar was found, and it was diagnosed as dentigerous cyst. And the histopathologic examination showed the same result. Marsupialization was operated through alveolar socket and the alveolar socket was protected with vaseline gauze, the obturator combined with space maintainer was followed by the operation. After the operation, the impacted permanent tooth was showing faster eruption speed than the other normal teeth.

Dentigerous cyst is the most common developmental odontogenic cyst of the jaw which is associated with unerupted teeth. Treatment modalities range from enucleation to marsupialization. Enucleation is the process in which the cyst is completely removed, and this is usually indicated for smaller lesions. Larger cysts can be treated by marsupialization, which is a process that consists of making a surgical cavity on the wall of the cyst, emptying its content and maintaining the continuity between the cyst and the oral cavity. This procedure allows decompression of the cyst, regeneration of the bone-defected area, and also lets the wall of the cyst change into normal mucosa. This technique will protect adjacent structures and will promote spontaneous eruption of succedaneous teeth previously surrounded by the cyst. These are two case reports of a 5-year-old and an 11-year-old boy with dentigerous cysts found regarding supernumerary tooth and pulpotomized mandibular primary molars, respectively. Due to the large size of the cysts, both cases were treated with marsupialization. This case report shows that in cases regarding large-sized dentigerous cysts, marsupialization can be an effective surgical technique that promotes spontaneous eruption of cyst-involved succedaneous teeth and the preservation of adjacent teeth.

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.

The aim of the present study was to identify the clinical characteristics and treatment outcomes associated with maxillary anterior dentigerous cysts in children. Among 55 patients who had been diagnosed with maxillary anterior dentigerous cysts, 33 patients had cysts located in the incisor region and 22 had cysts located in the canine region. Cysts in the incisor region were 7.2-fold more prevalent in male patients, while cysts in the canine region were 1.75-fold more prevalent in female patients. For cysts in the incisor region, marsupialization was performed in 21 cases and enucleation in 12 cases. In the canine region, marsupialization was performed in 20 cases and enucleation in 2 cases. Spontaneous eruptions of the displaced teeth in the incisor and canine region were 90% and 54.5%, respectively. Among patients which spontaneous eruption occurred, patients with cysts in the incisor region underwent orthodontic treatment more often due to malocclusion. This study is expected to be used as fundamental data for establishing future treatment plans by providing the analyzed results of distribution and characteristics of dentigerous cysts involving the maxillary anterior tooth.

In children, large odontogenic cysts affect adjacent anatomical structures as well as displace developing permanent teeth. Odontogenic cysts are treated via enucleation or marsupialization. This case reports a 5-year-old boy and a 10-year-old boy who have not only displaced 3 or more permanent teeth but also elevated the maxillary sinus floor due to the large size of the cyst in the maxillary anterior region. In both cases, marsupialization was selected to minimize complications. After marsupialization, a customized acrylic obturator, window opening, and orthodontic traction for eruption guidance were gradually attempted, and it showed a good prognosis, so we report these cases.
