We present two cases of multiple jaw cysts not associated with basal cell nevus syndrome. Case 1: a nine year-old boy visited CNU Hospital for orthodontic treatment and his radiographs showed cystic lesions surrounding the crowns of teeth #13 and #17 respectively, which were diagnosed as dentigerous cysts. Subsequently, two more cysts were found on his follow-up radiographs in 12 and 15 months. The two cysts were determined to be odontogenic keratocysts. The boy had no skeletal abnormalities and no skin lesions associated with basal cell nevus syndrome. Case 2: a fifty-eight year old man had three impacted third molars with pericoronal radiolucencies, which were diagnosed as dentigerous cysts. He had no additional abnormalities associated with basal cell nevus syndrome. Multiple jaw cysts can occur at any age, and periodic radiographic surveillance may be needed for any cases of impacted tooth.

낭은 액체 또는 반유동성 액체를 함유하는 상피세포층으로 둘러싸인 공동이다. 낭은 모든 연령대에서 진단될 수 있으나, 소아 청소년 환자는 성인들과 다른 병소의 종류와 양상을 보일 수 있으며, 후속 영구치가 발육 중이므로 치료법도 다를 수 있다. 본 연구는 2005년 1월부터 2015년 3월까지 최근 10년간 경희대학교 치과병원을 내원한 19세까지의 소아 청소년환자 중임상적, 방사선학적 및 조직학적으로 낭으로 확진된 253명의 환자들을 분석하였다. 그 결과 낭은 남아 142명(56.1%)에서 다소 많았으며, 치성낭이 209개(82.6%)로 대다수를 차지하였고, 전체적으로 발육성 낭이 염증성 낭보다 많았다. 발육성 낭에서는 함치성낭, 염증성 낭은 치근낭이 많았다. 한편 하악 구치부에서 발생 비율이 높았다. 환자들 중 많은 경우 임상 증상이 없었으며, 낭의 치료 방법으로는 적출술만을 시행하고 원인치 발거를 동시에 진행한 경우가 많았다.

악골에서 다수로 발생하는 낭은, 단독으로 발생하는 낭에 비해 매우 드물게 나타난다. 증후군을 동반하지는 않고, 악골 내에 다수의 낭이 발생한 경우를 다발성 악골낭 이라고 하는데, 소아에서 발생하는 다발성 악골 낭의 대부분은 각화낭성 치성종양(Keratocystic odontogenic tumor, KCOT)이다. 소아에서 나타나는 악골의 다발성 각화낭성 치성종양은, 기저세포모반증후군의 한 증상으로 발생할 수 있으므로, 악골의 방사선 사진에서 다발성 낭이 발견되면, 증후군을 의심해보고 임상 및 병리 검사를 하게 된다. 본 증례는, 다발성 악골 낭을 주소로 내원한 소아환자들로, 기저세포모반증후군을 의심하였으나 현재까지 증후군의 다른 증상들은 보이고 있지 않으며, 단지 수년간에 걸쳐서 종양의 재발과 수술을 반복하고 있는 경우이다. 악골의 다발성 낭 이외의 기저세포모반증후군의 증상들이 나타나지 않더라도, 나이가 들면 증후군의 다른 증상들이 나타난 경우의 보고도 있으므로, 소아에서 이러한 다발성 치성종양이 관찰되면, 지속적으로 방사선 및 임상 검사를 시행하여 증후군으로의 진행 여부를 관찰하는 것이 중요한 것으로 사료된다.

Several cases of jaw cyst-basal cell nevus-bifid rib syndrome are presented. This syndrome consists principally of multiple jaw cysts, basal cell nevi, and bifid ribs but no one component is present in all patients. The purpose of this paper is to review the multiple characteristics of this syndrome and present three cases in a family and additional 4 cases. The many malformations associated with the syndrome have variable expressivity. In the cases, multiple jaw cysts, palmar and plantar pittings, bridging of sella, temporoparietal bossing, hypertelorism, cleft palate, and dystopia canthorum have been observed.

Purpose: The aim of this study was to introduce a category of jaw lesions comprising cysts and tumors associated with scalloped borders. Materials and Methods: General search engines and specialized databases including Google Scholar, PubMed, PubMed Central, and Scopus, as well as an authoritative textbook, were used to find relevant studies by using keywords such as "jaw lesion," "jaw disease," "scalloping," "scalloped border," "scalloped margin," "irregular border," and "irregular margin." Out of 289 articles, 252 records were removed because they were duplicates, did not have a relevant title, or did not mention the frequency of findings described using the term "scalloped border." Finally, 37 closely related articles were chosen. Results: According to the relevant literature, scalloped borders are found most frequently in ameloblastoma, followed by simple bone cyst, central giant cell granuloma, odontogenic keratocyst, and glandular odontogenic cyst. Conclusion: The lesions most frequently reported to have scalloped borders are ameloblastoma, central giant cell granuloma, odontogenic keratocyst, simple bone cyst, and glandular odontogenic cyst.

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.

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.

Purpose : 1. Retrospectively evaluate the accuracy of tentative diagnosis or impression from the clinico-radio-graphic materials of jaw lesions which showed mixed lesions associated with teeth. 2. To observe the diagnostic importance of the calcified part of the lesions which appear as radiopaque areas. Materials and Methods: 14 cases of jaw lesions which showed mixed lesions associated with teeth were reviewed. These lesions were mostly diagnosed as adenomatoid odontogenic tumors (6 cases) or calcifying odontogenic cysts with (4 cases) or without odontomas (4 cases). The calcified elements of the lesions which demonstrated various sizes and patterns of radiopaque shadows resembled odontoid tissues in some cases but could not be defined in some other cases radiographically. Results : The final histopathologic diagnosis confirmed adenomatoid odontogenic tumors in 4 of the 6 cases. The remaining 2 cases turned out to be odontoma and ameloblastic fibroodontoma. The 4 cases of calcifying odontogenic cysts with odontomas were correct in 3 cases but remaining 1 case was just odontoma. The 4 cases of calcifying odontogenic cysts were proved to be odontogenic keratocyst, calcified peripheral fibroma, unicystic ameloblastoma and squamous cell carcinoma. Conclusion : The diagnostic accuracy of the adenomatoid odontogenic tumors and calcifying odontogenic cysts were high when the lesions show typical appearance. The calcifications which show radiopaque areas could be odontomas or dystrophic calficifations or remnants of bone fragments from resorption.

This clinical study was made of 214 cases of the jaw cysts which were diagnosed histopathologically in the Department of Oral and Maxillofacial Surgery, Wonkwang University Dental Hospital from Jan. 1, 1991 to Dec. 31, 1998. Medical records, radiographs, histopathological reports of 214 cases with jaw cysts were retrospectively reviewed. The results were as follows : 1. Among the total patient of 214 cases, male were 143 cases, and female are 71 cases, male predominated by the ratio of 2.04. 2. The periapical cysts and the dentigerous cyst are the most common cyst, irrespective of 116 cases(54.2%) and 58 cases(27.1%). 3. The periapical cyst has no gender prediction, male were 70 cases and female were 54 cases, the mean ages were 39.3 years(SD=18.4). The most common involving teeth were maxillary anterior teeth(59.7%). 4. The dentigerous cyst predominantly occurred in third decade (18 cases : 31%), and the mean ages were 31.9 years(SD=14.8). Dentigerous cysts predominantly occurred in male by the ratio of 7.29 (male : 51 cases, female : 7 cases). Maxillary anterior teeth(43.1%) and mandibular molars(32.8%) were most frequently involved. 5. The odontogenic keratocyst predominantly occurred in second and third decade and mean ages were 23.5 years(SD=17.2). The mandibular molars(60%) were most frequently involved. 6. All nasopalatine cyst occurred after fourth decade, mean ages were 49.5years(SD=10.4). In the gender incidence of nasopalatine cyst, 1 case occurred in female and 10 cases occurred in male. 7. In the surgical intervention of jaw cyst, cyst enucleation and marsupialization performed in 156 cases. Cyst enucleation with bone graft performed in 58 cases and iliac autogenous bone grafts most frequently performed in 29cases. 8. The diameter range of cyst enucleation with bone graft were from 15mm to 120mm with a cyst diameter of 33.3mm. (SD=15.2) The diameter range of cyst enucleation and marsupialization were from 7mm to 82mm with a cyst diameter of 20.4mm.(SD=9.0) The diameter of cyst enucleation with bone graft were significantly greater than diameter of cyst enucleation. (p<0.05) 9. Post-operative complications occurred in 9 cases(15.5%) in which cyst enucleation with bone grafts performed and occurred in 31 cases(19.9%) in which cyst enucleation.

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.
