Stafne bone cyst (SBC) is a bone defect usually located in the posterior portion of the mandible or mandibular angle below the inferior alveolar nerve. The cases of SBC involving multiple anterior tooth apices and penetrating the mandibular bone are extremely rare. Here we present a case of an anterior-positioned SBC mimicking periapical cyst, which penetrated the mandibular bone, with a review of the differential diagnosis.

The dentigerous cyst involving maxilla is rare disease in Otolaryngologic field. A case of 22-year-old male patient involving dentigerous cyst of the maxilla with chronic inflammatory signs has been presented. The occurrence of odontogenic epithelium in the wall of dentigerous cyst is a well known entity. This epithelium usually remains inactive and does not have clinical significance, but these small inactive islands of epithelium may be stimulated, resulting in chronic inflammation, ameloblastoma and squamous cell carcinoma. Therefore correct diagnosis and proper treatment are very important. The authors have recently experienced a case of dentigerous cyst causing a mild disfigulation of face. The cyst was surgically enucleated through sublabial approach.

치원성 각화 낭종의 임상적 방사선학적 양상을 연구하였다. 32명의 환자(21명의 남자, 11명의 여자)를 이 연구를 위하여 사용하였다. 환자들의 기록과 방사선사진을 통하여 성별 및 연령의 분포, 호발부의 방사선사진의 양상, 재발율 임상적 소견들을 조사하였던 바 아래와 같은 결과를 얻었다. 1. 남성이 여성에 비해 약 2배 호발하였고, 10대와 20대에서 가장 많이 발생하였다. 2. 호발부위는 하악의 구치에서 하악지에 이르는 부위였고 하악골이 상악골에 비해 호발하였다. 3. 원기성 낭종에서 각화성 변화를 일으킨 것이 가장 많았다. 4. 치근의 흡수를 많이 보였으며, 하악골에서 경계는 원형과 부채형(scalloped)이 거의 동등히 나타났고 상악골에서는 대부분 원형의 단발형 낭종이었다. 5. 높은 재발율을 보였다. 6. 감염이 되어 있는 경우가 많았다.

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.

The dentigerous cyst originates through alteration of the reduced enamel epithelium after the crown of the tooth has been completely formed, with accumulation of fluid between the reduced enamel epithelium and the tooth crown. The dentigerous or follicular cyst comprises about 20% of all dental cysts. It usually occurs between 20 and 30 years of age but is occasionally seen in children or in old people. The most common sites of this cyst are the mandibular third molar and maxillary cuspid areas, since these are the most commonly impacted teeth. Many of these cysts give no clinical symptoms until noticeable asymmetry of the face develops. Rarely it develops to an ameloblastoma, epidermoid carcinoma and mucoepidermoid carcinoma, so early removal leads to better result. Roentgenographic examination of the jaw involved by a dentigerous cyst will reveal a radiolucent area. Recently the authors have experienced a giant dentigerous cyst which produced the bony deformity of the maxillary and hard palate bone. The cyst was completely removed under the local anesthesia by Caldwell-Luc approach.

Nevoid basal cell carcinoma syndrome is an ecto-mesodermal polydysplasia with numerous manifestations that affect multiple organs. The syndrome is an autosomal dominant inherited, with a high penetration and visible expression. The syndrome is characterized by a series of associated anomalies such as cutaneous, dentofacial, skeletal, ophthalmologic, neurological, and genital anomalies. Generally, the jaw cysts are multiple odontogenic keratocysts, affecting any area of maxilla and mandible. Multiple odontogenic keratocysts of this syndrome are more recurrent than the keratocysts of non-syndrome, thus they are treated aggressively for complete removal. We report a case of multiple jaw cysts associated with nevoid basal cell carcinoma syndrome. In clinical and radiological examinations, frontal bossing, hypertelorism, mild mental retardation and two odontogenic keratocysts in both the maxilla and mandible were observed. Two cysts were treated by marsupialization. For the management of eruption of unerupted teeth, periodic recall check and orthodontic treatment are required.

낭은 상피세포로 싸여있는 병적인 공간으로 내부가 액체나 반액체로 채워져 있다. 악골에서 낭은 다른 골 부위에서보다 더 흔하게 발생하는데 이는 대부분의 낭이 치아 형성 후에 악골에 남아있는 치성잔류물로부터 발생하는 경우가 많기 때문이다. 구강악안면부에서 발생하는 낭은 연조직에서 발생할 수도 있지만 대부분 골내에서 발생하고, 법랑질 상피나 치배와 관련해 악골내에 발생하는 치낭성이다. 치낭성은 WHO분류에서 발생근원에 따라 크게 염증성과 발육성 기원의 두 가지 군으로 분류되고, 발육성 낭은 치성과 비치성으로 세분할 수 있다. 악골에 발생하는 낭은 대부분이 치낭성이며 가장 흔한 악골 낭종은 치근단낭으로 염증성이고, 발육성인 함치성낭과 치성각화낭도 다음으로 발생률이 높은 편이다. 소아환자에서 함치성낭과 치성각화낭의 발병률이 성인보다 더 높았다. 비치성낭 중에서 비구개관낭이 가장 많이 발생하며, 연조직에서 발생하는 낭과 상피세포 경계가 없는 낭성 병소인 가성낭(pseudocyst)은 드물게 관찰된다. WHO에서 치성각화낭과 서회화치성낭은 파괴적 성장을 하고 재발 경향이 높으므로 양성 낭성 종양으로 재분류하고 있다.

NBCCS is a hereditary disorder characterized by multiple defects of ectodermal and mesodermal structure, which is chiefly affected on skin, jaws & skeleton, CNS, eye and sexual organ. It is well associated with multiple odontogenic keratocyst on the jaws. Thus, we intended to investigate other anomalies presenting on NBCCS in cases of multiple odontogenic keratocyst which were treated in our hospital from 1980 to 1989. Here we reported 6 cases of NBCCS.

This study was aimed to suggest to better treatment method of jaw cyst that the maximum diameter was wider than 3cm, using different treatment and clinical and radiographic result. We divided the 60 patients into three groups, group A(20 patients) were treated with cyst enucleation and Decalcified Freeze-Dried Allogeneic Bone(DFDB) graft, group B(20 patients) were treated with cyst enucleation and autogenous bone graft, group C(20 patients) were treated with only cyst enucleation. Each group was evaluated with panoramic radiograph and clinical sign & symptom at pre-op and post-op(immediate, 6, 12, 24, 36 month). Bone density was evaluated with disital densitometer. The result was as follows : 1. Post-Op infection was higher in group C(4 pts.) than in group A(1 pt.) and B(1 pt.) 2. Post-Op gingival recession was higher in group C(3 Pts.) than in group A(1 pt.) and B(1 pt.) 3. Anatomic distortion was higher in group C(3 Pt.) than in group A(1 Pt.), and B(1 pt.) 4. Reoperation was done in two patients who were in group C 5. There were donor site morbidity in two patients 6. There was no significant difference between group A and B in their bony density in their follow up period(p>0.05). 7. There were significant differences between group A, B and group C in their bony density until post-op 24 months but a little differences at post-op 36 months(P<0.01)
