Primary teeth and the permanent successor must be understood as interdependent units, where each one of them interacts with and depends upon the other. The spread of pulpal inflammation in primary teeth to the periradicular tissues can lead to early eruption, enamel hypoplasia or hypocalcification, developmental arrest of permanent successor. Also the periapical inflammation cause permanent tooth displacement in various direction. We describe here two clinical cases of displaced permanent successor caused by periapical lesion of mandibular primary molar in children.

Scholars have been discussed about Korean Family History till now, however it is very doubtful that the maternal mother's family was disregarded. Perhaps, the stem of Korean family is a patrilineal society so that the maternal mother's family was disregar

Trauma to the primary incisors may cause developmental or eruptional disturbance of the permanent successors. Two cases illustrate developmental disturbances of arrested root formation, dilaceration, and eruptional disturbances of impaction, ectopic eruption of permanent successors caused by traumatic injury to deciduous incisors. The patient of the first case suffered trauma at the age of 4 years 7 months, causing alveolar bone fracture including the maxillary right primary central and lateral incisors that were immedi-ately extracted. The second patient had trauma episodes at the age of 3 years. Avulsion of the maxillary primary right central and lateral incisors were occurred due to trauma. After such trauma, regular follow-up including radiographs is necessary to detect early any possible interference with normal eruption of permanent successors.

The term 'impaction teeth' is used to designate a tooth which remains unerupted in jaw beyond the time at which it should normally be erupted. Most cases of impacted teeth reported in the literature are permanent teeth. The impaction of primary teeth occur rarely whereas impaction of second primary molars is more numerous than all other impactions. Failure of eruption of primary teeth may cause a number of complications, such as interference with development and eruption of successive permanent teeth, malocclusion, cystic change of tooth follicle. The clinican should consider the various treatment option available (a) No treatment and observation, (b) surgical extraction (c) space regainer. Proper treatment plan should be established after thought consideration of impacted tooth and it's relation with successive permanent tooth.

Joseon was a Confucian dynasty. It was ruled by Kings of the Royal family that had secured the orthodoxy of clan rules under Confucian ideas. Royal family was the main prop of Confucian culture and Kings were leaders who leaded society and culture from the top. Therefore, Kings should complete more strict and intense education than noblemen. The Royal family and the government should have to establish prime educational environments and systems to foster successors qualified for the throne. This study focused on educational institutes and educational ceremonies. Study on educational institutes could clarify the purposes of educational institutes that were installed along the growth of throne successors and the educational courses that successors completed by each period. On the other hand, study on educational ceremonies could make it clear how were throne successors given with authority and did they internalize the duty of sense as the leader to lead next generation. In addition, by tracing the form with which politics and education had combined each other through ceremonies, it could be learned that the ceremonies of Joseon Dynasty had have a unique 'educational function'.

50년대에 급속한 경제성장을 이룩한 서독은 수출증대를 위하여 대량생산제품의 개발을 통한 국제경쟁력 강화를 꾀하였다. 여기에서 디자인이 제품의 질적 요소로서 그리고 판매증진의 요소로서 이해됨으로써, 제품개발을 위한 디자인의 개발이 강하게 요구되고, 또한 디자이너 양성을 위한 대학의 필요성이 대두되었다. 이러한 사회적 요구에 힘입어, 울름 조형대학은 '53년 8월 그 문을 열게 되었다. 설립초기에서부터 이 대학이 가장 중요하게 내세운 것은 바우하우스의 계승이었다. 그러나 초대 학장 막스 빌의 현대예술 중심적 디자인 관과 바우하우스 교수법을 그대로 답습하는 기초교육과정은 - 과학적으로 객관화된 디자인을“정치적”으로 정립하고자 - 바우하우스 이념을 계승하여 새로운 사회건설을 지향하는 젊은 강사들과 대립되는 것이었다. '55년 토마스 말도나도가 학장직을 대행하면서부터, 과학과목들의 도입과 더불어 바우하우스 계승의 길이 새롭게 모색되기 시작하였다. 그러나 디자인의 과학화 과정에서 과학기술을 맹신적으로 따르는 기술교조주의라는 문제에 즉면 하게 되고, 디자인에서의 과학기술을 사회적으로 재정립하기 위한 방향이 모색된다. 이로부터 인본주의적 인공환경의 건설을 지향하는 사회적 디자인, 즉“환경디자인 Umweltgestaltung”개념이 개발되고, 이의 과학적 방법론이 연구되었다. 결국,“환경디자인”은 울름 조형대학이 궁극적으로 추구한 불변의 이상향이 되었고, 이의 실천을 위한 기본 방법은“유닛시스템디자인Unit System Design(Baukasten-Systemdesign)”이었다. 이와 같이 울름 조형대학은 바우하우스의 계승이라는 대 명제 하에 인본 적으로 객관화된 과학적 디자인 개발에 일관된 노력을 기울였다. 그러나 여기에서 나타난 - 후기산업사회의 인간 중심적 발전을 목적으로 새로이 정립된 - 인본주의라는“정치성”으로 인하여, 결국 '68년 9월 30일 그 문을 닫게 되었다.

Exfoliation of the primary teeth and eruption of the permanent teeth is a normal and predictable physiologic process. The accurate prediction of tooth development is of major importance in treatment planning for children. Norms that correspond to the child's age and development have been determined by many investigators. However, there are a variety of factors that may hasten, retard, or otherwise affect the normal developmental process. Among the factors that influence tooth eruption is the premature loss of primary teeth. An abscess of a primary molar, followed by bone resorption and early extraction or exfoliation may lead to premature eruprion of the permanent succesor, and a variety of clinical sequelae. I, hereby present the patients who have prematurely erupted permanent successor in Seoul National University Hospital Pediatric Dentistry, and report the clinical and radiologic characteristics, its sequelae, proper managements, and followed up findings.
