악안면 형성과정의 이상으로 인한 구조적 결함상태로 정의되어지는 악안면 기형(maxill-ofacial ogtal malformation)은 사고나 기능적(funct-ional) 장애로 인해 후천적으로 생길 수도 있으나 유전적 원인 등으로 인한 선천적 경우도 많다. 특히 후자의 경우에는 여러 증후군과 결합되어 나타나는 수가 많다. 치과의사는 치아이상이나 기능적 이상으로 인한 기형의 치료 및 예방을 담당할 책임이 있으며, 더욱이 새로운 진료실에서 직접 대면할 수 있는 최초의 의사가 될 수 있다는 점에서 특별한 기형외에도 전반적인 증후군에 대한 지식을 갖는 것이 중요하다. 악안면 기형환자에게는 전반적 검사가 필수적이며 방사선 분석, 치아모형 분석 등 다양한 분석이 필요하나, 여기에서는 주로 병력 청취나 시진을 통한 검사에 중점을 두어 서술하고자 한다.

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.

Dens invaginatus is a malformation of tooth resulting from an infolding of the enamel epithelium during tooth development. This malformation shows a broad spectrum of morphologic variations. This invagination frequently allows the entry of irritants and microorganism, which usually lead to necrosis of the adjacent pulp tissue and then to periapical or periodontal abscess. Root canal treatment of such tooth is often difficult because of the un usual form and complicated pulpal space. This article reports 2 cases of dens invaginatus in maxillary lateral incisors. The first case was successfully treated with $Ca(OH)_2$. In the second case, involved tooth was extracted and this extracted tooth was observed using the micro-computed tomography.

We report the rehabilitation of Class II malocclusion with multiple teeth fracture due to trauma. A multidisciplinary team approach was necessary to treat patient's problems such as bone fracture, malocclusion, and multiple teeth fracture. Emergency conservative treatment, orthodontic treatment and prosthetic restoration successfully restored the occlusion. However, special considerations were needed along the orthodontic treatment process due to the unexpected complications such as ankylosis, root resorption and detection of additional teeth fractures.

Dilaceration is a tooth abnormaly occuring in the histo-morphodifferention stage resulting from disturbance between the uncalcified and already calcified portion that affects both the crown and root. The involved tooth is usually the maxillary central incisor and it also shows high prevalence of impaction. The cause of dilaceration can be either from the trauma of the primary tooth, ectopic development of the tooth germ or from cysts. And it is also found in some cases of Otodental syndrome, Hurler syndrome, Cleidocranial dysostosis. The purpose of this study is to show that periapical lesions caused by dental caries can be another factor in causing dilaceration.

The purpose of this study was to investigate the relationship between morphology and number of deciduous teeth and the occurrence of other dental anomalies in their successors, and to evaluate the necessity of early diagnosis of dental anomalies in the primary dentition. Prevalence of double teeth and congenital missing teeth was investigated in 254(134 boys, 120 girls) panoramic radiographic films, taken by 2 to 7-year-old children in Chonnam National University Hospital from 2000 to 2005. And then it was examined that relationship of anomalies of the primary dentition and their successors. Among them 11 children(6 boys, 5 girls) had double teeth or missing teeth. And prevalence of the double teeth was 1.6% and missing teeth was 3.1%. One subject had double teeth in in the mandible and missing teeth in the maxilla. Of the 11 cases of dental anomalies in primary dentition, 7 cases had congenital missing tooth in their successors. This study suggests that the dental anomalies in the primary dentition induced high prevalence of the congenital missing of permanent successors in the permanent dentition.

Treacher Collins syndrome(TCS) is a rare, incurable condition occurring in approximately 1 of 25,000 to 50,000 births. It may occur as a spontaneous mutation out of genetically normal parents or it may be manifested as an autosomal dominant pattern. TCS is characterized by facial deformities such as, underdevelopment of the maxilla, mandible and zygoma, malocclusion, bilateral deformities of auricles, antimongoloid slant of the palpebral fissures. The syndrome is often associated with cleft lip and palate, ear malformations and hearing loss, short stature, and anomalies of the heart and skeleton. Respiratory difficulty associated with air way obstruction may also be observed, and there is considerable difficulty in airway management during general anesthesia. It is necessary that dentists provide safe dental treatments and guidelines to TCS patients by providing adequate understanding about the characteristics of the syndrome and proper ways of managements. The purpose of this study is to report the dental and medical characteristics of the patient who visited the Department of Pediatric Dentistry, Yonsei University for multiple dental caries treatment and to review the literatures of TCS.

수술과 교정의 혼합술식으로 안면부의 기형과 부수적으로 발생하는 부정교합을 치료하는 경향이 점차적으로 증가하고 있다. 수술-교정 술식은 과거 20년동안, 특히 1970년대에 무척 빠른 속도로 발전하였다. 수술-교정 술식이 발달함에 따라 이전에는 수술이나 교정치료 단독으로는 치료하기가 어려웠던 case들의 치료가 가능하게 되었다. 교정의사들은 성장이 완료된 성인의 심한 skeletal dysplasia를 치아이동에 의해서만 치료하는 데에는 매우 제한이 많다는 것을 인식하게 되었으며, 반면에 구강외과 의사들은 수술전후의 교정치료에 의해 더욱 좋은 수술 결과를 얻을 수 있는 동시에 좋은 functional occlusion을 이룰수 있다는 사실을 인식하였다. 이러한 수술-교정 술식은 교정의사들과 구강외과의사들에게 새로운 면들을 요구하고 있다. 좋은 치료결과를 얻기 위해서는 교정의사와 구강외과의사간의 긴밀한 협조관계가 필수적이다. 이러한 협조관계를 유지하기 위하여는 서로 상대 전문분야의 용어, 진단원리, 치료기법 등에 대한 이해가 선행되어야 한다. 이 논문에서는 진단, 치료계획, 수술전 교정치료, 수술술식, 수술후 교정치료, 증례보고의 순서로 기술하려 한다.
