Decompression is considered an effective treatment for odontogenic cystic lesions in the jaw. A variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors, radicular cysts, dentigerous cysts, and ameloblastoma. The purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment. The aim of this report is to describe an effective decompression tube using a stainless steel tube and wire for treatment of jaw cystic lesions.

BACKGROUND: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. METHODS: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. RESULTS: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. CONCLUSIONS: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.

cyst which were managed in the Department of oral and maxillofacial sugery from March 1994 to February 1998 was done. An following results were obtained. 1. Male were involved more than females by cyst in a ratio of 1.95:1 and most of the cases occurred in the secondary decades. 2. The primary site of radicular cysts were the anterior incisor area, dentigerous cysts were anterior incisor area and canine area, incisive canal cysts were maxillary anterior area, odontogenic keratocyst were the mandibular ramus area. The common symptoms were swelling(65 cases), pain(12 cases) and the mean duration of syptomatic period was 10 days. 4. The rates of histopathologic classification were radicular cyst(58%), dentigerous cyst(22%), incisive canal cyst(9%), odontogenic keratocyst(11%). 5. Average of Alk. phosphatase was 235(IU/L) at pre-twenty age and 102(IU/L) at post-twenty age. 6. In treatment modalities, enucleation was most common, odontogenic keratocyst was treated by enucleation and curettage for prevention of recurrence.]]>

PURPOSE: Basal cell nevus syndrome (BCNS), also known as Gorlin syndrome, is a rare autosomal dominant disorder. It is characterized by complex neoplastic syndrome with multisystemic manifestations, involving six major features. This article presents a rare genetic disorder and usage of the author's methods for odontogenic keratocyst, developed in the maxillary sinus. METHODS: A 67-year-old man was presented with large calcified maxillary mass and multisystemic manifestations and findings that matched with basal cell nevus syndrome. The calcified maxillary mass was removed via the versatile maxillary window and maxillary bone segment was repositioned. RESULTS: Histopathologic findings revealed that maxillary and mandibular lesions were odontogenic keratocysts and the skin lesions were basal cell carcinoma. CONCLUSION: Basal cell nevus syndrome is a rare genetic disease that requires surveillance and care for basal cell carcinoma and multisystemic problems. The author's method was satisfactory for maxillary odontogenic keratocyst in the aspect of the approach and reconstruction.

Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They are developmental epithelial-lined lesions which are formed from fluid accumulation in the space between the reduced enamel epithelium and the surface of crown. This may occure due to the obstructin of venous return caused by tooth impaction. The most prevalent location of dentigerous cysts are the third molar of mandible. While the single dentigerous cysts are the second most common odontogenic cysts following the radicular cysts of jaw, multiple cysts are observed in patients with some conditions such as mucopolysaccharidosis type IV, basal cell nevus syndrome, and cleidocranial dysplasia. They occur in young patients in the second or third decades of life, but it is a rare occurrence for children. A sixteen-year-old girl with painful swelling in the right mandible visited to our department. All routine laboratory test results were within normal limits. However, we were able to diagnose that she had facial asymmetry. Computed tomography showed a well-defined soft tissue mass obliterating right mandible ramus with an impacted tooth. We performed total enucleation of cyst and molar tooth. The pathology revealed a non-keratinized squamous epithelial lined cyst associated with an undamaged tooth.

The basal cell nevus syndrome is a well recognized entity, the major symptoms of which are basal cell nevi, multiple jaw cysts, skeletal anomalies, and ectopic calcification. The syndrome follows a hereditary pattern, which is characterized by a highly penetrant, autosomal dominant gene with multiple and variable effects. The patient often has a characteristic face, with frontal and temporoparietal bossing, which results in an increased cranial circumference. The eyes may appear widely separated, and 40 percent of patients have true ocular hypertelorism. Jaw cysts are one of the most constant features of the syndrome and are present in at least 75 percent of the patients. The cysts are odontogenic keratocysts and frequently multiple. Radiographically, the cysts in patients with basal cell nevus syndrome do not differ significantly from isolated keratocysts. The cysts in patients with this syndrome are often associated with the crowns of unerupted teeth; on radiographs they may mimic dentigerous cysts. We report a case of multiple odontogenic keratocysts associated with basal cell nevus syndrome with the literature of review.

This review article aimed to introduce a category of jaw lesions associated with impacted tooth. General search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks were used to find relevant studies using keywords such as "jaw lesion", "jaw disease", "impacted tooth", and "unerupted tooth". More than 250 articles were found, of which approximately 80 were broadly relevant to the topic. We ultimately included 47 articles that were closely related to the topic of interest. When the relevant data were compiled, the following 10 lesions were identified as having a relationship with impacted tooth: dentigerous cysts, calcifying odontogenic cysts, unicystic (mural) ameloblastomas, ameloblastomas, ameloblastic fibromas, adenomatoid odontogenic tumors, keratocystic odontogenic tumors, calcifying epithelial odontogenic tumors, ameloblastic fibro-odontomas, and odontomas. When clinicians encounter a lesion associated with an impacted tooth, they should first consider these entities in the differential diagnosis. This will help dental practitioners make more accurate diagnoses and develop better treatment plans based on patients' radiographs.

Dentigerous cysts are the most common type of developmental odontogenic cysts and the second most common odontogenic cyst of the jaw after radicular cysts. Dentigerous cysts are usually solitary, but can be multiple in patients with certain syndromes, such as mucopolysaccharidosis type IV. There are cases of multiple cysts occurring in non-syndromic patients as well. A fourteen-year-old girl presented to our department with painful swelling in the left cheek. Except for the bulging of the left nasal lateral wall, the physical examination was unremarkable and all routine laboratory test results were within normal limits. Computed tomography (CT) showed a well-defined soft tissue density obliterating both maxillary sinuses with a tooth in the medial wall. We removed the cyst and teeth with forceps via a large middle meatal antrostomy. The pathology revealed a non-keratinized squamous epithelial lined cyst associated with the teeth.

Dentigerous cysts are major pathologic entities found in dentistry, accounting for approximately 24% of all true cysts in the jaws. They are the most common type of developmental odontogenic cysts and the second most common odontogenic cyst of the jaw, after radicular cysts. They are associated with the crown of an unerupted or impacted tooth. About 95% of dentigerous cysts involve permanent dentition, and only 5% are associated with supernumerary teeth. To date, a dentigerous cyst containing multiple teeth has rarely been reported. Reported herein is a 51-year-old man who presented a history of painful palpable mass on the right cheek area, and who was found to have a maxillary dentigerous cyst containing multiple teeth. The cyst with multiple teeth was successfully removed via endoscopic endonasal and intraoral approaches.

odontogenic cyst(OKC), parakeratinized OKC, dentigerous cyst, and periapical cyst by the immunohistochemical assay using cell proliferation factor Ki-67, cell differentiation factor cytokeratin. To understand the invasiveness and recurrence rate of cysts, further can help patient treatment. The results were as follows. 1. The Ki-67 immunohistochemical assay showed that the epitherial cell proliferation decrease in the descending order of parakeratinized OKC, orthokeratinized OKC, dentigerious cyst, periapical cyst. 2. The high molecular weight cytokeratin(HM-CK) immunohistochemical assay showed positive at upper epitherium in parakeratinized OKC, but at basal layer in orthokeratinized OKC. 3. The low molecular weight cytokeratin(LM-CK) immunohistichemical assay showed negativity in the orthokeratinized OKC. This meant the orthokeratinized OKC showed positivity in less differentiated cells. 4. The cytokeratin immunohistochemical assay didn't show positivity at all, the cyst. It suggested that the parakeratinized OKC showed more invasiveness and recurrence rate. This immunohistochemical study should make a differential diagnosis of cysts and help patient treatment.]]>
