맹출 전 치관 내 흡수(pre-eruptive intracoronal resorption; PEIR)는 미맹출치 치관의 법랑상아경계하방에 위치한 방사선 투과상의 흔치 않은 병소이다. 맹출 전 치아에서의 PEIR은, 흡수 진행속도에 따라 외과적 노출술 후 수복 혹은 지속적 관찰로 치료가능하다. 하지만 맹출 후에는 우식 병소 발달의 위험이 높아 임상가의 대처가 늦을 경우 근관치료 등을 포함하는 심화된 수복치료를 진행하여야 한다. 본 증례는 어린이에서 PEIR로 인해 감염된 미성숙 영구치의 임상적 특징 및 치료에 관하여 보고하고자 한다.

함치성 낭종이란 퇴축법랑상피와 법랑질 표면 사이에 체액이 축적되어 치관이 내강의 안쪽에 있으며 치근은 바깥쪽에 위치하는 매복치 치관을 둘러싸는 치원성 낭을 의미한다. 함치성 낭종의 치료법으로는 적출술, 조대술, 감압술 및 외과적 절제술이 있다. 본 증례는 하악 제2유구치의 만기잔존을 주소로 내원한 환아들을 검사하였다. 두 환아에서 해당 제2유구치의 협측부에서 팽융을 관찰하였다. 두 환아, 모두 방사선사진상 하악 제2소구치의 치관을 포함한 단방성의 방사선투과상이 보였으며 조직검사 결과 함치성 낭종으로 진단되었다. 본 증례에서 발치와를 통한 조대술을 시술하였다. 제2유구치를 발거하고 바세린 거즈로 발치와를 보호한 후 익일에 보격장치를 겸한 obturator를 장착해 주었다. 시술 후 매복된 영구치는 정상 맹출속도보다 빠르게 맹출하는 양상을 보이고 있다.

법랑모세포 섬유치아종(Ameloblastic fibro-odontoma)은 하악 구치부에 호발하는 드문 혼합 치성종양이다. 방사선적 소견으로는 경계가 명확하고, 대부분에서 방사선 투과상과 불규칙적인 크기와 형태의 불투과상이 혼재된 양상으로 관찰된다. 조직학적으로 법랑모세포 섬유치아종은 법랑모세포 섬유종의 연조직 성분과 복합성 치아종의 경조직 성분을 모두 가지고 있다. 본 증례의 13세 2개월된 남자 환아는 원광대학교 치과대학 치과병원 소아치과에 하악 좌측 견치의 맹출 지연을 주소로 내원하였다. 맹출을 방해하는 병소를 적출하고 조직 생검한 결과, 법랑모세포섬유치아종으로 진단하였다. 지속적인 예후관찰 중 병소 제거 수개월 후 견치는 정상적으로 맹출하였다.

국소적 섬유연골성 이형성증(FFCD)은 소아에서 일측성 경골 내반 소견을 보이는 드문 양성 질환이다. FFCD는 근위 경골 내측 골간단과 골간의 이행부에 오목한 방사선 투과 음영 소견을 보이는 전형적인 방사선 소견을 지니고 있다. 경골 내반이 병변 부위에서 발생한다. 내반의 교정과 골결손의 치유가 흔히 자발적으로 일어나기도 하지만 골교정술을 요하기도 한다. 저자들은 절제 조직 생검술로 진단하고 절골술 및 골이식술을 시행함으로써 치유한 FFCD에 의한 일측성 경골 내반 1예를 문헌고찰과 함께 보고하는 바이다.

The goal of this treatment is the surgical-orthodontic eruption of impacted permanent teeth associated with a large dentigerous cyst in a preadolescent patient. Although enucleation of the entire cyst and the extraction of impacted teeth are common treatments, missing permanent teeth cause several problems in young patients. In this report, an 11-year-old female visited with the chief complaint of a large radiolucent lesion from the mandibular anterior area to the left mandibular posterior area. The permanent left canine and premolars were displaced toward the mandibular inferior border area. The extraction of infected deciduous teeth and marsupialization were performed. After 4 months, orthodontic buttons for forced eruption were applied to the impacted permanent teeth. The teeth emerged into the oral cavity 3 months after the orthodontic treatment. Although the root form was abnormal, there were no other pathogenic signs. The alveolar bone had a normal trabecular pattern and the teeth appeared to be well maintained at postoperative 24 months.

Solitary plasmacytomas are rare and account for 5-10% of all plasma cell disorders. These tumors are categorized as solitary plasmacytomas of bone(osseous) or extramedullary plasmacytomas(non-osseous). About a half of solitary plasmacytomas of bone occur in the spine but rarely in the skull. We report a case of solitary plasmacytoma of the skull presented with a painless palpable left parietal calvarial mass in an otherwise asymptomatic 38- year-old man. Skull radiographs showed a large radiolucent lesion with well defined non-sclerotic margins. Computed tomograph scan demonstrated a markedly enhancing mass extending from the epidural to the subcutaneous space. The patient underwent surgery and tumor was completely excised. Pathological examination showed tumor to be a plasmacytoma synthesizing IgG. Postoperatively, the patient received radiotherapy. There was no evidence of systemic involvement on postoperative laboratory wokups. Our recommended treatment is a complete surgical excision combined with postoperative radiation therapy. The patient should be follwed carefully for more than 10 years because of either local recurrence or possible progression to multiple myeloma.

Botryoid odontogenic cyst (BOC) is considered a rare multilocular variant of the lateral periodontal cyst. In this report, a 67-year-old male visited with chief complaint of severe mobility on mandibular incisors. Multilocular radiolucent lesion was seen from the right premolar to the left premolar area, involving almost the whole mandible. Histologically, the botryoid odontogenic cyst showed focal nodular thickening of the lining epithelium. These thickening often showed swirling appearance of the cells. Cyst enucleation and bone graft on mandible anterior and both body area were performed under general anesthesia, and postoperative healing was favorable without recurrence.

The author observed and analyzed the age, sex, chief complaint and radiographic finding of sixty-one cases of benign odontogenic tumors seen in Yonsei Medical Center, for the period of Jan. 1979 to Aug. 1989. The results were as follows: 1. Benign odontogenic tumors of 61 cases included 52 cases (85.3%) of ameloblastoma and odontoma, and 9 cases of other lesions. Radiographically, the border of the lesions were well-defined. 2. Ameloblastoma constituting twenty-seven cases (44.3%) occurred the average age of 31.1 years and had a 3:1 male predominance. The most common complaint was swelling (20 cases, 74.0%) and followed by pain (13 cases, 48.2%). Radiographically, the most common site was mandibular body area (74.0%) and the lesions were mainly multiocular radiolucency; in 17 cases (63.0%) and unilocular radiolucent lesion were seen in 10 cases (37.0%). 16 cases (59.3%) showed the resorption of roots of adjacent teeth. 3. Odontoma constituting twenty-five cases (41.0%) discovered at the average age of 16.9 years and had a 3:2 male predominance. The most common complaint was delayed eruption of tooth (8 cases, 31.0%) and 7 cases (27.0%) detected on a routine radiograph of the area. Radiographically, 17 cases (68.0%) were of compound type and 8 were of complex variety and compound odontomas were common in the anterior maxilla, whereas complex odontomas occurred more frequently in the posterior mandible. 19 cases (76.0%) showed the impaction of adjacent teeth.

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare form arising within the jaws. PIOSCC is not related to the oral mucosa, presumably developing from remnants of the odontogenic epithelium. Because odontogenic cyst epithelium often transforms malignantly into PIOSCC, it could be misdiagnosed as odontogenic cyst based on a relatively ill-defined radiolucent lesion. Therefore, definite diagnosis is established from histological examination of biopsy samples taken during cyst enucleation in many cases. The present study is reported with a case of patient complaining of discomfort on his mandible. He was diagnosed as a putative dentigerous cyst and underwent a cyst enucleation treatment. After definite diagnosis as PIOSCC was established based on histologic findings, partial mandible resection and mandible reconstruction were performed. Up to the present, 10 months follow up of the patient showed satisfactory healing without recurrence and abnormal findings; thereby, we are reporting this case with literature review.

Calcifying epithelial odontogenic tumor (CEOT) is a rarely reported benign tumor, accounting for 0.4-3% of all odontogenic tumors. Approximately 150 cases have been reported in the literature between 1958 and 2003. The age range of CEOT varies from 8 to 92 years with mean of 36.9 years, and the occurrence of the lesion in both genders is almost equal. It has 2 clinico-topographic variants: the intraosseous (94%) and the extraosseous (6%) type. The intraosseous type has a predilection for mandible (maxilla : mandible ratio of 1 : 2). The intraosseous CEOT commonly associated with non-erupted teeth accounts for more than half (52%) of the cases and usually appears as painless swelling that causes bony expansion. The location of diffused round-shaped calcifying material is inside the connective tissue stroma and epithelial islands. The tumors tend to be located toward the tooth crown, which usually has a unilocular radiolucent region containing variant radiopaque materials radiologically. In this paper, we report a case of CEOT occurring in the left mandibular first premolar of a 23-year-old female and present a brief review of the literature.
