  • Odontogenic keratocyst is classified as a developmental odontogenic cyst and is believed to arise from cell rests of the dental lamina. It accounts for 3% to 11% of all jaw cysts and they occur twice as often in the mandible as in the maxilla. Histologically, the cysts are lined by stratified, keratinizing, squamous epithelium. Daugther cysts or microcysts are often observed microscopically. The recurrence rate has been reported variously, but is known by its high recurrence rate. These lesions are more common in males than in females, occur over a wide age range and are typically diagnosed during the 2nd and 3rd decade. The diagnosis depends on the cyst’s microscopic features and is independent of its location and radiographic appearances. This cyst is a radiolucent lesion that is often multiloculated, has a smooth or scalloped border. The cyst is characteristically located in the body and ramus of the mandible, and often occurs in conjunction with an impacted tooth. This case report describes an odontogenic keratocyst on the lower right molar area of an 8-year-old girl. The cyst was removed under the general anaesthesia, and is being checked regularly for any recurrences.

  • 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.

  • 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.

  • Marsupialization and decompression constitute a well-established procedure for treating cavitary bone lesions of the jaw. The technique can be a primary treatment option, especially for pediatric patients with large cysts or lesions involving vital anatomical structures, such as a developing tooth germ. In this procedure, a decompression stent, such as a customized acrylic obturator or space-maintaining appliance, silicone tube, or nasal cannula, is inserted to maintain the patency of the cyst. However, this may cause clinical problems, such as irritation or trauma to the adjacent tissues, as well as discomfort to the patient, or failure of the stent due to cyst shrinkage. It can also be a reason for patient noncompliance. In the cases described here, a minimally invasive marsupialization technique using a metal tube made from a 16-gauge needle was used for odontogenic cysts in pediatric patients associated with unerupted teeth. Through this method, the lesions were removed, with patient cooperation, and the cyst-associated teeth erupted spontaneously.

  • Nasopalatine duct cysts are the most common non-odontogenic developmental cyst originating in the incisive canal of maxilla and occuring in approximately 1% of the population. Clinical presentation is mostly asymptomatic in small cysts, but sometimes shows swelling, pain and drainage when it is infected. The definite diagnosis should be based on clinical, radiological and histopathologic findings. Marsupialization of the cystic tissue can be performed, however, complete surgical excision is the the choice of treatment of nasopalatine duct cysts. We report a case of nasopalatine duct cyst occurred in the midline of hard palate treated by complete excision via transoral approach.

  • Dentigerous cysts generally encompass the crown of an unerupted tooth. These cysts are usually solitary. They are the second most common odontogenic type of cysts following radicular cysts, and are frequently associated with impacted mandibular third molars or maxillary canines. Most multiple cysts found in the jaw are odontogenic keratocysts associated with the nevoid basal cell carcinoma syndrome, mucopolysaccharidoses and cleidocranial dysplasia. Although a single dentigerous cyst is well documented in the medical literature, including the prevalence, treatment and prognosis, multiple dentigerous cysts without any systemic symptoms is unusual. Furthermore, cases involving both the maxilla and mandible are especially rare. We present the case of an 11-year-old boy with nonsyndromic multiple dentigerous cysts associated with a mandibular second premolar and a maxillary canine. The treatment was conservative and included marsupialization and eruption guidance. Further follow up is planned to rule out additional problems and the possible identification of a syndrome.

  • A dentigerous cyst is the most common developmental odontogenic cyst. Patients with dentigerous cyst usually feel no pain or discomfort. If it is not treated, tooth eruption might not only be impeded, but also let the tooth translocate to the unusual area. So, early detection and appropriate treatment are important. Enucleation & marsupialization are the best options to treat a dentigerous cyst. Treatment plan depends on patient's age, health, preserve & protect of important structures, and sort of cyst. In these dentigerous cysts cases, by marsupialization and using obturator, affected tooth could be achieved spontaneous eruption into the dental arch even though they were badly dislocated.

  • The dentigerous cysts originate 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. Next to the radicular cyst, they are the second most common type of odontogenic cyst. They occur over a wide age range with a peak frequency in the 2nd to 3rd decade. A substantial majority involve the mandibular third molars, followed in order of frequency by the maxillary permanent canines, mandibular second premolars, and maxillary third molars. With regard to the treatment of these cysts, the marsupialization procedure with obturator is recommended during the age when the eruptive force of the teeth is still strong. It can be effective when preservation of the displaced teeth is desirable. We treated the dentigerous cyst by marsupialization with obturator and guided the eruption of involved teeth to normal position. And we got the results as follows : 1. Severely dislocated teeth associated with dentigerous cyst erupted into proper position. 2. The enamel hypoplasia and the root deformity were observed some cases. 3. The bone expansion and defect were healed without infection and recurrence.

  • Dentigerous cyst is one of the most prevalent types of odontogenic cysts in the jaw. Usually dentigerous cysts begin to develope through an accumulation of fluid between remnants of the enamel organ and subjacent tooth crown which is developing or submerged. The teeth most often involved are mandibular third molars, maxillary canines, and mandibular premolars. And the cysts usually occur in the second or third decade of life. The treatment of dentigerous cysts-enucleation, marsupialization, and fenestration-is dictated by the size, environmental structures of the lesion, and desirability of conserving involved tooth. Marsupialization is a conservative technique which allows the reduction or elimination of cystic lesion by making it an accessory compartment of the oral cavity in the case where complete enucleation is not desirable. Marsupialization is thought to be the most suitable method of treatment for the conserving of the involved tooth, thus guiding eruption of it. We report the positive outcome got from marsupialization in dentigerous cysts with review of literature.
