1. Periphelal odontoma는 매우 드문 질환으로 확진을 위해서는 생검이 필수적이다. 2. Peripheral odontoma는 치은의 종창을 동반하며 서서히 성장하는 임상적 특징을 가진다. 3. 골내 치아종과 마찬가지로 peripheral odontoma의 치료로는 완전한 외과적 절제가 추천되고 예후 또한 양호하다.

We investigate the clinical characteristics of odontoma in childhood and adolescence. A retrospective analysis was performed in 105 patients under 15 years old who were diagnosed with odontoma in Kyungpook National University Dental Hospital, the department of pediatric dentistry between 1 January 2008 and 31 December 2013. The ratio of compound odontoma, immature odontoma and complex odontoma were 67.6%, 21.9% and 10.5%, respectively. Odontoma was more prevalent in males and the ratio of males to females was 1.5:1. The age of patients ranged from 3 to 14 years old with an average age of 9.3 years old. The odontoma was more frequently located in the maxilla (73.3%) than in the mandible(26.7%). In 98 cases, it was treated by surgical removal. Among adjacent teeth impacted by odontoma, 26 cases (34.7%) of successional permanent teeth were erupted when only odontoma were removed and 6 cases (8.0%) were erupted when surgical exposure was performed. Orthodontic tractions were performed in 43 cases (57.3%). In conclusion, odontoma could cause complications such as impaction of teeth. If they are found early and treated properly, high eruption success of successional permanent teeth can be obtained. The occurrence frequency of immature odontoma are higher than that of complex odontoma, and they are observed intensively in anterior maxillary teeth. Therefore, it is considered that they are important causes of dental impaction in anterior maxillary teeth.

The term odontoma, first introduced by Broca, was originally applied to all odontogenic tumors. Related to the clinical and histological differences, 2 groups of odontoma were defined: compound odontoma and complex odontoma. Complex odontoma is more common in the mandible than in the maxilla, usually occuring in the mandibular premolar-molar area. And this consists of small mass of irregularly arranged enamel, dentine, cementum, and connective tissue, but tooth-like structures are not found. In our case, 34 year old man was diagnosed as the complex odontoma of maxillary sinus by the physical exam, Panex, and C.T scan. We sectioned and removed it, and then confirmed the diagnosis histopathologically. Its uncommon location and size made us report that case and review the literature concerned.

Ameloblastic odontoma is a mixed odontogenic tumor, which is characterized as being extremely rare, displaying aggressive clinical behavior, resembling a mixed radiopaque and radiolucent radiographic appearance and containing both ameloblastoma and a composite odontoma. Seven-year-old boy complaining of delayed eruption of the left lower permanent 1st molar came to the department of Oral & Maxillofacial Radiology at Chonbuk National University Hospital. The list of our radiographic differential diagnosis included the dental follicle, compound odontoma, complex odontoma and cystic odontoma. The microscopic analysis showed the lesion with the characteristics of an ameloblastic odontoma. The obtained results were as follows; 1. The area was asymptomatic, but the delayed eruption of the left lower permanent 1st molar was observed. Radiographically, well-defined widened pericoronal radiolucency containing several tooth-like radiopacities involving the impacted left lower permanent 1st molar and well-defined round radiolucency containing irregular radiopaque mass were observed. 3. Histopathologically, several tooth-like structures, odontoma components with the area of typical enamel, dentin and pulp, and ameloblastic components with typical follicular ameloblastoma were observed.

악골에서 비교적 흔한 빈도로 발생하는 치아종은 치배조직의 과성장으로 인하여 발생한다. 세계보건기구에서는 치아종을 복잡 치아종과 복합 치아종으로 구분하고 있다. 치아종은 악골내 모든 부위에서 발생할 수 있지만 치아와 유사한 복합 치아종은 비교적 상악 전치부에 호발하고, 불규칙한 형태를 나타내는 복잡 치아종은 하악 구치부에 호발한다. 치아종의 원인은 정확히 알려져 있지 않으며 치배에 대한 국소적인 외상이나 감염이 주된 요인으로 추측되고 있고, 최근에는 유전적인 원인에 대해서도 연구되고 있으나 아직 확실히 입증되지는 않고 있다. 일반적인 증상이 없기 때문에 일상적인 방사선 검사에서 주로 발견되고 영구치의 맹출지연이나 유치의 만기잔존 등의 증상이 있을 수 있다. 치아종은 구강내의 어떤 부위에서도 발생이 가능하고 드물기는 하지만 상악동, 하악의 하연, 하악지 및 하악과두 하방에서 발견되기도 하며, 이공 부위에서 발생되는 경우도 있다. 치아종은 발육중인 치열과 악궁에 미치는 영향을 최소화하기 위하여 발견되는 즉시 낭포 및 주위 연조직을 함께 외과적으로 제거하는 것이 바람직하다. 환자의 연령과 치과치료에 대한 협조도, 영구치열의 발육상태, 치아종의 악골내 위치 및 동시적인 치과치료가 요구되는 가를 고려하여 외래 진료실에서 하는 경우도 있고 전신마취를 통하여 하는 경우도 있다. 본 증례는 치아종의 악골내 위치가 깊지 않고 치과치료에 대한 협조도가 양호하다고 판단되는 환아에서는 외래 진료실에서 국소마취하에 수술하여 치료하였고, 연령이 어리고 치아종의 악골내 위치가 깊어 장시간의 시술 시간이 요구되고 동시에 보존적인 치과치료가 필요한 환아에서는 전신마취하에 치료한 것을 보고한 것이다. 두 증례에서 수술 4개월 후 외과적 결손 부위에 골이 형성되었고, 매복된 영구치의 맹출이 정상적으로 이루어진 것으로 나타났다.

Odontomas are nonaggressive, hamartomatous developmental malformations composed of mature tooth substances and may be compound or complex depending on the extent of morphodifferentiation or on their resemblance to normal teeth. Among them, complex odontomas are relatively rare tumors. They are usually asymptomatic in nature. Occasionally, these tumors become large, causing bone expansion followed by facial asymmetry. Odontoma eruptions are uncommon, and thus far, very few cases of erupted complex odontomas have been reported in the literature. Here, we report the case of an unusually large, painless, complex odontoma located in the right posterior mandible.

치아종(odontoma)은 치성기원의 과오종(hamartoma)으로서 법랑질, 상아질, 치수, 백악질 등의 조직으로 구성되어 있고, 조직학적으로 복합치아종과 복잡치아종으로 구분된다. 치아종은 영구치의 맹출을 방해하며 낭종 형성과 인접골 파괴를 유발할 수 있으므로 제거되어야 한다. 제거를 위해서는 적출술을 시행하고 재발은 거의 일어나지 않는다. 악골 외에 존재하는 치아종은 상대적으로 드문 질환으로 악골 내 치아종과 조직학적으로 유사한 특징을 보인다. 본 증례에서는 3세 여자 환아가 하악 우측 구치부 종창을 주소로 본원에 내원하였다. 정기적인 검사 결과 종창의 크기가 증가하였고, 방사선 검사를 통해 병소의 석회화를 확인하여 적출술을 시행하였다. 방사선 검사에서 골내 침식 소견은 관찰되지 않았고, 조직학적 검사를 통해 변연성 치아종으로 확진되었으며, 양호한 치료 결과를 보였기에 보고하는 바이다.

Purpose : The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. Materials and Methods : We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Results : Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Conclusion : Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

Odontoma is the most common odontogenic benign tumor, and the treatment of choice is generally surgical removal. After excision, bone grafts may be necessary depending on the need for further treatment, or the size and location of the odontoma. Although the osteogenic capacity of a demineralized tooth was verified as early as 1967 by Urist and many other investigators, the cumbersome procedure, including a long demineralization time, may be less than comfortable for clinicians. A modified ultrasonic technology, with periodic negative pressure and temperature control, facilitated rapid and aseptic preparation of demineralized teeth for bone grafts. This approach reduces the demineralization time dramatically (${\leq}80$ minutes), so that the graft material can be prepared chairside on the same day as the extraction. The purpose of this article is to describe two cases of large compound odonotomas used as graft material prepared chairside for enucleation-induced bony defects. These two clinical cases showed favorable wound healing without complications, and good bony support for future dental implants or orthodontic treatment. Finally, this report will suggest the possibility of recycling the benign pathologic hard tissue as an alternative treatment option for conventional bone grafts in clinics.
