The calcifying odontogenic cyst(COC) is considered to occupy a position between a cyst and an odontogenic tumor-having charateristics of both. Gorlin and col. described the COC for first time as an own pathological entity in 1962. Clinically, the COC represents 1% of the odontogenic lesion. It is possible to be found from the first decade to the eight decade but is more frequent during the second decade. It affects in same proportion the maxilla and jaw, being the most in tooth-bearing area of the jaw. This case of COC associated with an unerupted tooth which appeared in the right mandible of 22-year-old woman, was reported. This case report is to present a review of the literature relates to this case of COC and its treatment, discuss clinical, radiographic, histological and therapeutic aspects.

This study aimed to identify the characteristics of jaw cysts among children and adolescents treated at the Kyung Hee University Dental Hospital from 2005 to 2015. A retrospective observational study was conducted of 269 jaw cysts diagnosed in 253 patients. The following variables were recorded: gender, age, prevalence and location of lesions, clinical symptoms and treatment. Statistical analyses were performed using the SPSS (version 20.0). Our results suggest that the cysts are slightly more prevalent in males. Cystic lesions of the jaws in children are predominantly odontogenic and developmental in origin. Dentigerous cysts predominate in developmental cysts and the most frequent diagnosis is radicular cysts in inflammation cysts. The most common location of the cysts is in the mandible, particularly the lower molar region. In numerous cases, the patients have no clinical symptoms. Most cysts were surgically enucleated with tooth extraction. Furthermore, our findings demonstrate that the characteristics of jaw cysts in children are distinctive and differ in several respects from the corresponding distribution of jaw cysts in adult population. Therefore, knowledge of the clinical, radiological and histopathological behavior of jaw cysts and periodic radiographic examination are key factors for early diagnosis and adequate treatment of jaw cysts in children.

This study evaluated the use of endoscopy to examine jaw cysts during the operation. Fifteen jaw cysts were explored with a endoscope immediately before and after enucleation. Endoscopic findings were evaluated and recorded with video tape. Before enucleation, there were many white fibrous floating materials within the cystic cavity. Cystic lining showed smooth and regular appearance with capillary network. However, there were some fibrous scar tissues and irregular architecture in preoperative infection. After enucleation, there were white shiny bony surfaces with fresh vascular network. In some cases, floating fibrous tissues remained after removal.

Keratocystic odontogenic tumors can occur in any area of the maxilla or mandible. According to their size, location, and relations with surrounding structures, they are treated by cyst enucleation or enucleation after either marsupialization or decompression. Enucleation is performed when cysts are not large and when only minor damage to adjacent anatomical structures is expected. Although marsupialization and decompression follow the same basic bone-regeneration principle, which is to say, by reducing the pressure within the cyst, the former leaves a large defect after healing due to the large fistula necessary to induce the conversion of the cyst-lining epithelia to oral epithelia; the latter leaves only a relatively small defect, because of the continuous washing carried out by means of a tube inserted into a small hole in the cyst. In the latter case too, a decompressor appropriate for the focal position is required, owing to the importance of maintaining the device and controlling for oral hygiene. We report herein decompression treatment with a patient-customized device for an extensive cyst in the anterior region of the mandible.

Ameloblastoma is a common odontogenic tumor originating from the dental lamina, reduced dental epithelium and rests of Malassez, and represents 10% of all odontogenic tumors of the jaw. Unicystic ameloblastoma is normally encountered in young patients, and often occurs in the mandible, and is particularly associated with an impacted tooth. We encountered an unicystic ameloblastoma arising from a dentigerous cyst after the treatment of a radiolucent lesion on the mandible.

The calcifying odontogenic cyst is rare lesion having features of both cyst and neoplasm. Clinically it frequently occurs in young adult and more frequent in the anterior area of the jaw. Radiographically, this lesion has several radiopaque foci within unilocular or multilocular radiolucency. The authors experienced cystic and neoplastic types of calcifying odontogenic cysts in the anterior area of the mandible in a 16-year-old male and 21-year-old female patients who suffered from pain, swelling and teeth displacemeent on the affected area. And we discussed the clinical, radiological and histopathological features with a brief review of the literatures.

Multiple jaw cysts are one of the most constant features of the basal cell nevus syndrome. Basal cell nevus syndrome is inherited as an autosomal dominant trait with variable expressiveness. This syndrome comprises a number of abnormalities such as multiple nevoid basal cell carcinomas of the skin, skeletal abnormalities as bifid rib and fusion of vertebrae, central nervous system abnormalities as mental retardation, eye abnormalities with multiple jaw cysts. The odontogenic keratocysts in patients with this syndrome are often associated with the crowns of unerupted teeth and huge size; on radiographs they may mimic dentigerous cysts. The most important feature of the cyst is its extraordinary recurrence rate. Since recurrence may be long delayed in this lesion, follow-up of any case of odontogenic keratocyst with roentgenograms and clinical examination of basal cell carcinoma are essential for at least five years after surgery. We report the result of 7-year follow up after cyst enucleation associated with basal cell nevus syndrome with the literature of review.

Purpose: This study was done to know the usefulness of fractal analysis when evaluating the radiologic changes after decompression on jaw bone cystic lesions using fractal analysis. Materials and methods: 30cases of cystic lesions were followed up after decompression. Panoramic image was used to observe radiologic changes around the cystic lesion. The part of the panoramic image which showed radiologic change was defined as region of interest(ROI); The fractal dimension of the ROI was calculated using box-counting method. Results: Using sign-rank test, there was a statistically significant difference in fractal dimensions after decompression therapy(P<0.0001). The fractal dimensions statistically increased after decompression(the median of D:0.12). Conclusions: The ROI after decompression showed higher fractal dimensions which offer the objective proof of the bone healing around cystic lesions after decompression treatment.

The purpose of this study is to investigate on the clinical and radiographic patterns of residual cyst of the jaw for early diagnosis and treatment. The auther studied 87 cases of residual cyst with regard to age, sex distribution, the site of the lesion and several radiographic features. The results were as follows: 1. The average age was found to be 42.6 years, with a range of 15 to 84 years. The incidence was highest in the third and fourth decades(50.6%) and total 87 cases consist of 47 males and 38 females. 2. The common clinical symptoms were pus discharge, swelling, pain and no symptoms was presented in 5 cases(12.5%). 3. Residual cysts were found to be 46.0% maxillary anterior region, 18.4% maxillary molar region, 17.2% mandibular molar region and to be more common in the maxilla(70.1%) than in the mandible(29.9%) 4. Most of residual cysts were unilocular type(86 cases, 98.8%), showing distinct border(62 cases, 71.3%) with smooth margin(78 cases, 89.7%). 5. The adjacent teeth showed root resorption in 13 cases(14.9%), and root divergence in 16 cases(18.4%). 6. The residual cysts extended to the nasal fossa(22 cases, 22.5%), the maxillary sinus(19 cases, 19.4%) and caused the displacement of the mandibular canal wall (11 cases, 11.2%)

Calcifying odontogenic cyst(COC) is comparatively rare in occurrence. COC represents about 1% of jaw cysts, and although it may occur in soft tissue, it is most commonly found within bone. Both the intraosseous and extraosseous forms occur with about equal frequency in the maxilla and mandible, mainly in the incisor and canine areas The most notable features of this pathologic entity are histopathological and include a cyst lining demonstrating characteristic "ghost" epithelial cells with a propensity to calcify and the occasional association of this finding with certain odontogenic tumors including the odontoma and the ameloblastoma. In this case, COC was associated with anterior wall of the maxillary sinus which appeared in the anterior maxilla of 64-year-old woman, was reported. We report that the clinical experience of COC with review of literatures.
