구치부 반대교합은 유치열기와 혼합치열기에서 종종 나타나는 부정교합으로서,유병율은 7∼23%로 다양하게 나타난다. 이는 상악 치아의 협측 교두가 대합되는 하악 치아의 협측 교두의 설측에 교합하는 상태이며,하나의 치아 또는 한 치아군에서 나타날 수 있다. 구치부 반대교합의 경우, 보통 자발적 교정이 이루어지지 않으므로, 발견되는 즉시 치료해주는 것이 추천된다. 치성이나 기능성의 경우 성장함에 따라 골격성으로 이행하여 악골의 변형을 초래하고 교정적인 수단으로 개선이 불가능한 상태로 악화될 가능성도 있으므로 조기에 치료하는 것이 효과적이며,이러한 반대교합의 치료 방법으로는 하악의 변위를 유발하는 조기접촉을 제거하기 위한 교합조정,협소한 상악궁의 확장,치열궁내 비대칭을 치료하기 위한 개개 치아의 배열 등의 방법이 있다. 본 증례에서는 유치열기와 초기 혼합치열기 아동에서 구치부 반대교합이 관찰되어 치아의 선택적 삭제와 상악궁의 확장으로 반대교합을 교정한 후 정기적 검진시 양호한 결과가 관찰되기에 이를 보고하는 바이다. Posterior cross-bite is a relatively frequent malocclusion in primary and early mixed dentition and the reported prevalence of posterior cross-bite varies from 7% to 23%. It has been defined as a transverse discrepancy in arch relationship which the palatal cusp of the upper posterior teeth do not occlude in the central fossa of the opposing lower teeth, and can be manifested in a single tooth or in a group of teeth. Posterior cross-bite does not often self-correct and therefore immediate treatment is recommended. Occlusal adjustment to eliminate premature contact that causes mandibular deviation, expansion of narrow maxillary arch, arrangement of the individual teeth to treat asymmetry within the dental arch are the methods of treating cross-bite. In the present case, functional posterior cross-bite was observed in the primary and the early mixed dentition children. The children were treated by the slow maxillary expansion and occlusal adjustment. The outcome of periodic examinations after the correction of cross-bite was favorable.
외과적 정출술을 이용한 치관-치근 파절된 미성숙 영구치의 치험례

치아의 치관-치근 파절은 치아파절이 치관과 치근에 걸쳐 발생되어 법랑질,상아질 및 백악질까지 이환된 경우로 정의 되며,치수이환여부에 따라 복잡파절과 비복잡파절로 분류될 수 있다. 치관-치근 파절의 빈도는 유치열에서 2%, 영구치열에서 5%로 나타나며,보통 상악 전치부에 호발한다. 이러한 치관-치근 파절된 치아의 수복을 위해서는 생물학적 폭경이 유지되어야 한다. 이를 위하여 사용되는 방법은 골 삭제 후 치은절제술,교정적 견인,외과적 정출 후 수복하는 방법과,인위적으로 발치하여 근관치료와 수복 후 재식하는 방법 등이 있다. 이중 외과적 정출술은 치아를 발거하여 파절부를 치은 연상으로 이동시켜 재식하는 방법으로서,이는 치관부 파절편이 임상치근의 1/2 미만인 경우에 적응증이 될 수 있으며,발견하지 못한 다른 파절편을 직접 시진할 수 있고 때로는 파절선을 순측에 위치시켜 치료시 사야확보 및 접근이 용이하다는 등의 장점이 있다. 본 증례에서는 외상으로 치관 치근 파절된 미완성 치근단의 상악 중절치를 가진 환아에서 외과적 정출술 후 근관치료와 광중합복합레진을 이용한 치관수복을 시행하였으며,정기적 검진시 양호한 결과가 관찰됨을 확인할 수 있었다. Crown-root fractures occur throughout both crown and root, and are defined as fractures involving enamel, dentin and cementum. The fractures may be grouped according to pulpal involvement into complicated and uncomplicated one. Crown-root fractures often occur on maxillary anterior teeth and comprise 5% of injuries affecting the permanent dentition and 2% in the primary dentition. To restore crown-root fractured tooth, biologic width must be maintained. For maintaining biologic width, such methods as gingivectomy following osteoplasty or orthodontic extrusion or surgical extrusion are available. Surgical extrusion is a method that extracts the tooth and replants the fractured tooth supragingivally. It is indicated when the length of the crown fragment is less than half the length of the clinical root. In these cases, root canal treatment and crown restoration using light-cured composite resin were performed after surgical extrusion, In following periodic examinations, favorable outcome was observed.

Purpose : This study was conducted to estimate incidence, mortality and survival rate of lung cancer in the elderly people in Korea. Methods : Study population was Korean Elderly Phamacoepidemiologic Cohort (KEPEC). The lung cancer incidence cases were detected from three different sources, medical utilization database of the Korea Medical Insurance Corporation (KMIC), the database from the National Cancer Registry, and the database from the Regional Cancer Registry. The hospital survey to confirm the final diagnosis of the potential cases was conducted. A specialist on lung cancer reviewed the abstracted data to confirm the final diagnoses. The lung cancer death cases were detected from the mortality database at National Statistical Office. Incidence rate, survival rate and mortality rate of lung cancer and their 95% confidence intervals were estimated with SAS Window ver.8.1. Results : There were 213 confirmed lung cancer cases in KEPEC between Jan. 1994 and Dec. 1998. Age-standardized incidence rate of lung cancer to the Korean population was estimated to be 316.9 per 100,000 person-years in male and 65.2 per 100,000 person-years in female. Age-standardized mortality rate of lung cancer to the Korean population was estimated to be 342.3 per 100,000 person-years in male and 84.8 per 100,000 person-years in female. One years survival rate was 17% in male and 11% in female. Two year survival rate was 2% in male and 4% in female. Conclusion : Age-standardized incidence rate, age-standardized mortality rate and survival rate of lung cancer in the elderly Korean may be useful for further study and making health policy for managing lung cancer in the elderly.

Purpose: This study was to apply head and neck massage to patients in intensive care unit and to inventigate the effect of that massage on sleep and state anxiety. Method: The subjects in this study were 27 patients who were admitted in medical intensive care unit. The study was performed from June thru September of 2005 on the One-group pretest-posttest design and the sleep, state anxiety of the subjects were measured before and after head and neck massage. For data analysis, paired t-test and Pearson correlation coefficient were utilized. Result: The first hypothesis that the subjects might have a better sleep after being exposed to head and neck massage was accepted. The second hypothesis that the subjects might feel less state anxiety afrer being exposed to head and neck massage was accepted. The third hypothesis that the sleep of the ICU patients maight be correlated to their anxiety was accepted, as there appeared correlation between their sleep and anxiety. Conclusion: Head and neck massage is identified as one of independent nursing interwentions to improve the sleep of ICU patients and ease their anxiety, and it is necessary to apply it to clinical practices.

Ketorolac (KA) and ketorolac tromethamine (KT) is the nonsteroidal anti-inflammatory drugs (NSAIDs) and has been used widely. To improve its frequent administration by control of drug release. we prepared SLM of KA and KT using Mirj 45 and 52 as surfactants and tripalmitin and tristearin as lipids by spry drying method SLM, as a disperse system for injection, were evaluated by measurement of particle sizes. SEM and drug release pattern As a result. spherical SLM were prepared and their particle size were in the range of 25-125 μm, which were dependant on the types and contents of lipid and sururfactants. Their dissolution rate were decreased as increasing lipid contents.
