한윤범,이제호,최형준,손흥규,김성오,송제선,최병재 대한소아치과학회 2009 大韓小兒齒科學會誌 Vol.36 No.2

외상에 의한 치아의 함입은 치아가 치조골 방향으로 변위되어 있는 상태이다. 함입성 탈구는 다른 유형의 탈구성 손상에 비하여 드물게 발생하고, 낙상에 의한 경우가 많으며, 소녀보다는 소년에서 호발하는 것으로 보고되었다. 치아가 함입되었을 때, 치수괴사나 유착, 치근흡수, 근관폐쇄, 변연골 상실 등과 같은 합병증이 발생할 수 있으며, 치아 경조직과 치아 지지조직 등의 손상이 동반되는 경우가 흔하므로, 예후를 예측하고 정확한 진단 및 치료계획을 수립하는데 어려움이 있다. 함입된 치아의 치료는 자발적으로 재맹출하기를 기다리거나, 교정적 견인 또는 외과적으로 재위치 시키는 방법이 있다. 이 증례는 외상으로 인하여 상악 좌측 중절치가 함입되었다는 주소로 내원한 6세 7개월 된 여아에서, 함입된 치아의 자발적인 맹출을 기대하였으나 맹출이 되지 않아서, 교정적으로 견인하여 맹출시킨 경우로 양호한 결과를 얻었기에 이를 보고하는 바이다. Traumatic intrusion is a type of injury that involves axial displacement of a tooth toward the alveolar bone. Its occurance is relatively rare compared to other types of luxation in permanent dentition. It is more common in boys than in girls, and most common etiology of intrusion is fallen down. Various complication may occur following traumatic intrusion, such as pulp necrosis, root resorption, pulp obliteration and marginal bone loss. In addition, traumatic intrusion is commonly combined with hard or soft tissue injuries. Therefore, it is difficult to establish proper treatment plan. Choice of treatment for an intruded tooth by trauma include waiting for spontaneous re-eruption, orthodontic repositioning, and surgical repositioning. In this case, we repositioned the intruded central incisor using orthodontic traction, in a six-year old girl, which failed to re-erupt spontaneously.

치은 섬유종증은 유리 치은과 부착 치은이 점진적으로 증식되는 비염증성 질환이다. 대부분 가족력이 있으며 영구치 맹출과 함께 발병하지만 유치 맹출 시기에, 드물게 출생 시부터 나타나기도 한다. 본 6세 여아의 경우 태어날 때부터 치은의 일부가 증식되어 있었고 가족력 및 치은 증식을 유발하는 약물을 복용한 병력은 없었다. 구강 내 검진 시 섬유성 치은 증식이 관찰되어 절제 생검을 시행하였고 그 결과 치은 섬유종증으로 진단하였다. 치은 섬유종증의 치료는 치은 절제술과 철저한 구강 위생의 관리이다. 그러나 치료 후 재발성 때문에 치료 시기에 대해서는 논란 중이다. 일반적으로 영구치가 모두 맹출 한 이후에 치료할 것을 추천하지만 조기 치료는 구강의 기능 및 환아의 심미적, 심리적인 문제점을 개선시켜 주는 장점이 있다. Gingival fibromatosis is a non-inflammatory oral disease, characterized by slowly progress enlargement of the free and attached gingiva. Gingival fibromatosis may have familial tendency. Gingival enlargement usually begins with the eruption of the permanent dentition but can also develop with the eruption of the primary dentition. In this case, a 6-year-old female had gingival enlargement at birth. There was no familial, medical and pharmacologic history of gingival overgrowth. Treatment is gingivectomy with a rigorous program of oral hygiene. Recurrence of gingival fibromatosis may well be inevitable. Therefore there is no general aggrement as to the timing of surgical intervention. Generally the best time is when all the permanent teeth have erupted. However early intervention can improve oral function and esthetic and psychologic effect.

The purpose of this study is to develop a inquiry learning instrument and to evaluate the effectiveness of experiment in the concept-forming about mapping and interpretation of the geological map. Unfortunately no proper experimental instruments on the content of this study has been utilized in the current domestic Earth Science textbooks. In this study, the geological structure models with 4 different dips were developed. In order to evaluate the effectiveness of the experiment, we prepared a test consisted of 10 problems and compared the test results performed by the control group who conducted the experiments along with regular class with another test results performed by comparative group who participated only regular class without experiment. The control group is consisted of 102 girls high school students in Taegu area, and the comparative group is 104 students. The test results are as follow : ⅰ)The mean of the test results of the control group (X_A) is 7.18, while that of comparative group(X_B) is 6.38. ⅱ)The difference of the test scores between two groups has been turned out to be highly significant at the 0.05 level of significance. (t=3.270 at the criterion for significance, α=0.05 and the degree of freedom, df=206). This suggest that the class learned by the experiment is more effective in the concept-forming of the making and interpretation of the geological map than the class only learned by lectures.

Difficulties arise in prediction of maintenance of the graft volume and viability of graft over time when a bone graft used for facial reconstruction. A bone-to-bone contact between the graft and the recipient bone is imporant for creeping substitution and survial of the recipient bone is important for creeping substitution and of the grafted bone. An adequate blood supply is also essential to ensure the survival of any live cells of the surface of the graft. Our study was designed to determine which one is an important factor viability of the grafted bone in Korean adult dogs : a bone-to-bone contact or overlying soft tissue. Blocks of outer table of the parietal bone were placed at the maxillae subperiostially in 4 different ways : bone-to-bone contact groups(groups Ⅰand Ⅱ)with placing a silicone membrane over the grafted bone and soft tissue contact groups(groups Ⅲand Ⅳ)with placing a silicone sheet between the grafted bone and the recipient. In groups Ⅰand Ⅲ, the cancellous surfaces of the parietal bone was placed on the recipient and the cortical surfaces were placed on the recipient in groups Ⅱ and Ⅳ. Caliper techniques were used to study the rates of volume maintenance of the grafts at 6, 12, and 20 weeks after bone grafting. The volumes of the living bone were quantified microscopically using a modified point-countiong technique. The volume is reduced in a similar rate with time in all groups. At 6 week, living bone cells increased in soft tissue contact groups Ⅲ and Ⅳ however, and increased in bone to bone contact groups Ⅰand Ⅱ at 12 and 20 weeks. there were osteoblastic proliferation and laminated mature bones in group Ⅰand Ⅱ. But osteoclasts and their associated osteolytic changes were still seen near the silicone membrane in group Ⅲ and Ⅳ, which may imply a continuing resorptive process with time. In summary, revascularization from the overlying soft tissue is important for the graft survival in early stage of the bone grafting while bone-to-bone contact may be essential in a later stage.

The aim of this study is to estimate the prevalence of HPV types(16, 18) in cervix of gynecologic patients and to elucidate the relationship of HPV types(16, 18) and clinical characteristics. Human papilloma virus(HPV) has attracted attention as one of the viruses linked to human cancers. Numerous clinical, epidemiological, and molecular studies indicate that certain genital HPV types are associated with cervical carcinoma. Of 100 types of HPV identified today, at least 40 have been found in the anogenital mucosa. A classification of these types into three groups with differing pathogenicity has been proposed: HPV type 6, 11, 42, 43, and 44 are detected more frequently in benign lesions such as condylomata; HPV type 31, 33, 35, 51, 52, and 58 are found more often in low grade squamous intraepithelial lesions than invasive lesions; and HPV 16, 18, 45, and 56 are predominant in high grade squamous intraepithelial lesions and invasive carcinoma. To detect HPV types prevalent in carcinoma of the uterine cervix, a type-specific, sensitive polymerase chain reaction(PCR)-based assay for HPV types 16, 18 was applied to 18 cervical carcinomas(15 squamous cell carcinomas and 3 adenocarcinomas), 21 cases of cervical intraepithelial neoplasia(CIN), and 42 samples of cervicitis and histologically normal. DNA extraction from cervical swab was done using DNAzol™(MBI, USA) and Nested PCR was done using HPV detection kit(Bioneer, Korea). The amplified product was analyzed directly on the basis of the site of ethidium bromide-stained band visible after agarose gel electrophoresis. The results were as follows 1. The positivity rates of HPV type 16 and HPV type 18 were 12.5%(90/718), 2,5%(18/718). so, HPV 16 positive cases(12.5%) was five folds as HPV 18 positive cases(2.5%) 2. Forty eight percents(39/81) of HPV 16 or HPV 18 positive cases were CIN, microinvasive cancer. 3. Age, Gestation number, Clinical stage, Histologic cell type in relation to HPV types were not statistically significant.
