A cystic compound odontoma in the maxillary sinus occurred in a 13-year-old boy. who had missing right upper third molar without having the history of extraction of the wisdom tooth. He complained nasal stuffiness. headache. and pain on the affected face. resembling any sign and symptoms of the maxillary sinus problems. The cystic compound. sized 2 x 1.5 cm in diameter was pedunculated and attached on the posterior wall of the right maxillary sinus and above the antral floor. The location of the compound odontoma in the maxillary sinus was confirmed after panoramic. waters. spiral tomographic. CT examinations and surgical exploration. Its location was on the medial. posterior. superior to the normal position of the maxillary third molar or the maxillary dental arch. The cystic odontoma in the maxillary sinus made the patient have the signs and symptoms of maxillary sinusitis. The cystic compound odontoma might be originated from the dental lamina of the missing upper right third molar. The 'V principle' of the upper jaw growth and the pneumatization process of the maxillary sinus could explain why the compound odontoma had peduncular shape and the location of odontoma was on the medial. superior to the normal position of the maxillary dental arch.

The author studied clinically and radiologically 55 cases which had been diagnosed as odontoma in SNUDH. The obtained results were as follows: 1. In sex distribution, there was no prevalence in both sexes. And the incidence was the highest in the 2nd decade. (16 patients, 29%) 2. There were 42 cases of compound odontoma (76%) and 13 cases of complex odontoma (24%). In most cases, compound odontoma was located at the anterior portion (34 cases, 81%) and complex odontoma at the posterior portions (9 cases, 69%). 3. There was no apparent clinical symptom in compound odontoma (83%), but in complex odontoma, 80% of case show swelling. 4. The adjacent root resorption was not observed in any case. 5. Five cases radiographically diagnosed as cystic odontoma were not confirmed histopathologically.

An odontoma is a slow growing and nonaggressive odontogenic tumor composed of enamel, dentin, cementum, and pulp tissue. The etiology of odontomas is unknown, although local trauma, infection, and genetic factors have been suggested. Odontomas are classified as compound odontoma or complex. A 20-year retrospective study was performed on 36 odontomas from the files of the Department of Oral Pathology at Chosun University School of Dentistry. Fifty-six percent of the patients were compound odontoma and 44% were complex odontoma. 56 percent of the patients were female and 44% were male. The odontoma is most often diagnosed in the second decade of life, during routine radiographic examination. The usual presenting symptoms are an impacted or and unerupted tooth, a retained primary tooth. Other less frequent signs and symptoms are pain, swelling, suppuration, foul odor, tooth mobility. In our patients were treated by enucleation of the tumor, and related teeth were treated by surgical extraction or orthodontically assisted eruption.

치아종은 외배엽성 상피세포와 중배엽성 세포의 과성장으로 형성되는 혼합종양이다. 대부분 정상 치아 발생 시기 동안 형성되며 어느 정도 크기까지만 자라므로 진성 종양이 아닌 과오종으로 여겨진다. 형태에 따라 복합 치아종과 복잡 치아종으로 구별된다. 복합 치아종은 주로 구강 전방부에서 발견되며 작은 치아와 비슷한 방사선 불투과성 구조물을 함유하고 있는 병소이다. 치아종의 치료는 대부분 보존적인 외과적 적출술이 추천되며 재발은 거의 없다. 본 증례는 유치 및 영구치의 맹출 장애를 일으킨 복합 치아종으로 진단된 세 어린이에서 병소의 외과적 적출술을 시행하고 약 1년간 관찰한 결과 자발적 맹출을 보여 이에 보고하는 바이다.

치아종은 치아조직의 비정상적인 과성장으로 인해 형성되는 외배엽성 상피세포와 중배엽세포로 구성된 혼합종양이다. 양성 치성 종양 중에서 가장 흔하며 신생물이라기보다 과오종으로 보고 있다. 치아종은 악골내 모든 부위에서 발생할 수 있지만 치아와 유사한 복합 치아종은 비교적 상악 전치부에 호발하고, 불규칙한 형태를 나타내는 복잡 치아종은 하악 구치부에 호발한다. 일반적인 증상이 없어 일상적인 방사선 검사에서 주로 발견되며 영구치의 맹출지연이나 매복, 유치의 만기잔존 등의 원인이 될 수 있지만 영구치의 선천적 결손을 동반한 증례는 매우 드물다. 치료는 외과적 제거가 추천되며 완전한 적출시 재발은 드물다. 본 증례는 영구치의 선천적 결손을 동반한 복합 치아종 환자에 대하여 보고하는 바이다.

치아의 맹출지연을 일으키는 여러 원인 중 치아종은 법랑질, 상아질, 치수와 같은 치아를 구성하는 조직을 갖춘 harmartoma로 complex odontoma(복잡 치아종)와 compound odontoma(복합 치아종)로 구분된다. 치아종의 원인에는 외상, 감염, 치아발육상의 장애, 유전적 요인 등을 들 수 있으며, 호발 부위는 상악 전치부와 하악 구치부이다. 이 중 compond odontoma는 악골의 전방부에, complex odontma는 악골의 후방부에 잘 발생하는 경향이 있는데 대부분 악골내에서 발생하지만 드물게 점막을 뚫고 치조골의 상방으로 석회화 된 종괴가 맹출한 형태의 치아종을 erupted odontoma라 한다. erupted odontoma는 매우 드문 질환으로 일반적으로 맹출지연을 일으키지는 않는다. 본 증례는 맹출이 지연된 하악 제 1대구치 치관 상방에 나타난 erupted complex odontoma를 제거 후 치아를 맹출 시키는데 양호한 결과를 얻었기에 보고하는 바이다.

The purpose of this study was to obtain information on the clinical and radiographic features of the odontomas in the jaws. For this study, the authors examined and analyzed the clinical records and radiographs of 119 patients who had lesion of odontoma diagnosed by clinical and radiographic examinations, The obtained results were as follows: 1. Odontoma occurred the most frequently in the 2nd decade(45.4％) and occurred more frequently III males (60.5％) than in females(39.5％). 2. The most common clinical symptom was the delayed eruption of the teeth(34.2％). 3. The type of lesions was mainly observed as compound odontoma(80.8％), and internal pattern of the complex odontoma was unevenly radiopaque(73.9％). 4. The compound odontoma frequently occurred in anterior portion of the maxilla(57.7％) and mandible(30,9％), and complex odontoma frequently occurred in anterior portion of maxilla(34.8％) and posterior portion of mandible(30.5％). 5. The effects on adjacent teeth were impaction of teeth(71.7％) and prolonged retention of deciduous teeth (31.7％), 6. The impaction of the teeth occurred in anterior portion of maxilla (44.2％) and mandible ( 19.2％), but root resorption of the adjacent teeth were not seen, 7. The boundary to adjacent structure was well-defined, the lesions appear as radiopaque mass with radiolucent rim.

Ameloblastic fibro-odontoma(AFO) is a rare mixed odontogenic tumor. It is composed of connective tissue characteristic of an ameloblastic fibroma and calcified tissue as a complex or compound odontoma. AFO usually presents itself as an asymptomatic swelling of jaw or failure of tooth eruption. The lesion usually occurs in individual less than 30 years old. The differential diagnosis of this tumor includes odontoma, ameloblastoma, and ameloblastic fibroma. This report describes an ameloblastic fibro-odontoma occurring in maxilla of sixteen-year-old female. The lesion was treated by surgical enucleation and curettage without extraction of the involved canine(#23). This patient has shown no sign of recurrence during postoperative 34 months. So we report our case with review of literatures
