Rieger syndrome is a rare, autosomal dominant genetic disorder characterized by malformation of the anterior chamber of the eye(goniodysgenesis) coincident with hypodontia. It may also be accompanied by a spectrum of dental, craniofacial and somatic anomalies. Mutations in paired-like homeodomain transcription factor2(PITX2) are associated with the syndrome, and its frequency in the general population has been estimated to be 1 : 200,000. In the present case, the patient, 4 year 7 month-old female, had posterior embryotoxon and polycoria. The maxilla was retrusive in cephalometric radiography. She had congenital missing on #52, #62 and some tooth germs of permanent tooth were not detected in panoramic radiography. The purpose of this paper is to report the dental and craniofacial findings and review the pertinent literature through this case.

본 연구의 목적은 치아 회분말과 연석고 및 알긴산을 혼합하여 이식한 후 초기 골 형성을 알아보는 데 있다. 백서 30마리의 두개골에 8mm 직경의 골결손부를 형성한 후 인간의 치아 회분말과 연석고 및 알긴산을 혼합하여 이식한 후 대조군, 치아 회분말과 연석고 처치군, 그리고 치아 회분말과 연석고 및 알긴산 혼합 처치군에서 각각의 골 결손부 치유과정을 조직병리학적, 조직형태계측학적으로 비교 관찰하였다. 통계학적으로 주간 변화(4주, 8주)는 유의하지 않았고, 각 그룹 간에 있어도 치아 회분말과 연석고 처치군과 치아 회분말과 연석고 및 알긴산 혼합 처치군 간 모두(4주, 8주) 유의한 차이가 없었다. 그러나 이들 치아 회분말과 연석고 처치군과 치아 회분말과 연석고 및 알긴산 혼합 처치군은 대조군에 비해서는 유의하게 우수한 신생골 형성을 보였다. 비록 통계학적으로는 치아 회분말과 연석고 처치군과 치아 회분말과 연석고 및 알긴산 혼합 처치군이 유의한 차이를 보이지 않았지만 치아 회분말과 연석고 및 알긴산 혼합 처치군에서 보다 더 우수한 신생골 형성 경향을 보였다. 뿐만 아니라, 신생골의 내용면에서도 치아 회분말과 연석고 및 알긴산 혼합 처치군에서 좀더 많은 신생 직조골의 융합이나 골 소주형성이 관찰되어 신생골의 형성 및 성숙에 알긴산이 역할을 담당하는 것으로 사료되었다. 결론적으로 골결손부 치료 방법으로 치아 회분말과 연석고 처치군 또는 치아 회분말과 연석고 및 알긴산 혼합 처치로 결손부에 이식하는 것은 신생골 형성의 양적, 질적 개선에 통계학적으로 유의하며, 알긴산을 이식재와 함께 처리한 경우에 신생골 형성의 양적, 질적 개선에 도움을 줄 수 있을 것으로 사료된다.$1^{\circ}C$ 냉수로 세척하고 PETE tray로 포장하여 $4^{\circ}C$로 저장한 경우 깻잎 고유의 초록색과 향을 유지하고 있어 저온냉수 세척과 tray 포장이 세척 청경채의 선도 유지에 효과가 있는 것으로 나타났다.1%,\;pendimethalin\;1.3{\sim}2.9%$ 및 $3.8{\sim}10.8%,\;ethoprophos\;0.6{\sim}2.7%$ 및 $0.1{\sim}0.3%$이었다. 인공강우실험 후 공약의 토심별 분포를 살펴 본 결과 alachlor와 ethopropho는 토심 $10{\sim}15cm$까지 이동하였고, ethalfluralin과 pendimethalin는 대부분 토심 5 cm 이내에 잔류하였다. 경사도 30%의 경우가 10%에 비하여 각 농약의 유실량이 $0.2{\sim}1.9$ 배 증가하였는데 유출수에 의한 농약의 유실량 차이는 유출수 중 농도 차이로 판단되며, 유실토양에 의한 농약 유실량 차이는 토양 유실량과 관계되는 것으로 생각되었다. 농약의 강우에 의한 유실은 복잡하게 작용하는 많은 환경적 요인에 의하여 영향을 받지만 정교하게 구성된 환경 시나리오에 의하여 예측 가능할 것으로 판단되었다.고 도라지는 물에 우려 푹 삶았고, 감자, 송이 등은 잘게 썰어 쌀과 함께 밥을 조리하였다. 4. 약선 음식조리방법 약선음식의 재료는 평상시 식생활에 사용되고 있던 식품들의 기능성분과 약이성을 이용하여 만성적인 질병과 급성적인 복통 설사 등에 재료의 전처리를 통해 죽으로 많이 이용하였다. 특히 곡류 등은

Objectives: The purpose of this study was to analyze the influence of four lifestyle-related diseases, diabetes, hypertension, obesity and hypercholesterolemia, on oral health in the rural elderly in Korea. Methods: We enrolled 399 subjects over 60 years of age over a six year period, year 2000-2006/ year 2001-2007. All subjects received a routine health examination as part of a program conducted by the National Health Insurance Corporation at Seongju-gun Public Health Center in Gyeongsangbuk-do Province, South Korea. All subjects were surveyed and examined to determine their general and oral health statuses. Results: Our results suggest that the duration of lifestyle-related diseases has a significant influence on oral health. The following factors were all significant in the results of analyses: duration of diabetes, tooth decay, which teeth had decayed, missing and filled teeth(DMFT), duration of hypertension, and duration of obesity and hypercholesterolemia(p<0.05). Our results also suggest that the number of lifestyle related diseases has a significant influence on oral health. Subjects with more than two diseases had significantly greater numbers of missing teeth and greater numbers of DMFT(p<0.01). The results of simple regression analysis indicate that patients exhibiting longer durations of diabetes also exhibit more tooth decay, and that patients exhibiting longer durations of hypertension and obesity are characterized by greater numbers of missing teeth. The longer the duration of any of the four lifestyle-related diseases we considered, the more DMFT we observed. Multiple regression analyses also demonstrated that longer duration of lifestyle-related disease was associated with greater numbers of missing teeth. As the number of lifestyle-related diseases increased, DMFT also increased. Conclusions: In summary, lifestyle-related diseases such as diabetes, hypertension, obesity and hypercholesterolemia have significant influences on oral health in the elderly. In this context, the prevention and management of lifestyle-related disease is critical for the maintenance and promotion of oral health.

The purpose of this study was to examine dental complications and to evaluate the effects of initial treatment age, treatment modalities, and treatment duration on the disorder after radiation and chemotherapy in pediatric cancer patients. For 93 children with clinical and radiographic data, the number of teeth, the morphology of teeth, the shape of the roots, and development status of the dentition were evaluated. Dental development disorders were found in 61.3% of the children. The mostly found abnormality was root deformity with the prevalence of 31.2%. In children submitted to the therapy before the age of 6, the number of missing teeth (p = 0.029) and microdontia (p = 0.003) were greater compared to the children who started to receive the treatment after the age of 6. The combination of radiation and chemotherapy showed significantly greater incidences of missing teeth (p = 0.030), microdontia (p = 0.046), and root deformity (p = 0.009) when compared with the sole application of chemotherapy. When the children were submitted to anticancer therapy for 18 months or longer duration, greater number of missing teeth (p = 0.032), microdontia (p = 0.011), root deformity (p = 0.025), and total number of teeth affected (p = 0.036) were observed compared with duration less than 18 months. The number of dental abnormalities increased when the children were treated at earlier ages, with combination of radiation and chemotherapy, and for longer period of time.
