The purpose of this study was to compare the apical microleakage in root canal filled with Resilon by methacrylate-based root canal sealer or 2 different self-adhesive resin cements. Seventy single-rooted extracted human teeth were sectioned at the CEJ perpendicular to the long axis of the roots with diamond disk. Canal preparation was performed with crown-down technique using Profile NiTi rotary instruments and GG drill. Each canal was prepared to ISO size 40, .04 taper and 1 ㎜ short from the apex. The prepared roots were randomly divided into 4 experimental groups of 15 roots each and 5 roots each for positive and negative control group. The root canals were filled by lateral condensation as follows. Group 1: Gutta-percha with AH-26, Group 2: Resilon with RealSeal primer & sealer, Group 3: Resilon with Rely-X Unicem, Group 4: Resilon with BisCem. After stored in 37℃, 100% humidity chamber for 7 days, the roots were coated with 2 layers of nail varnish except apical 3 ㎜. The roots were then immersed in 1% methylene blue dye for 7 days. Apical microleakage was measured by a maximum length of linear dye penetration after roots were separated longitudinally. One way ANOVA and Scheffe' s post-hoc test were performed for statistical analysis. Group 1 showed the least apical leakage and there was no statistical significance between Group 2, 3, 4. According to the results, the self adhesive resin cement is possible to use as sealer instead of primer & sealant when root canal filled by Resilon. 본 연구의 목적은 Resilon을 이용한 근관충전시 methacrylate-based root canal sealer와 자가-접착 레진시멘트의 사용에 따른 치근단 미세누출을 비교해 보는 것이다. 70개 단근치를 ProFile NiTi rotary instrument와 GG drill을 이용해 근관성형 하였다. 치근을 4개의 실험군 (n = 15)과 2개의 대조군 (n = 5)으로 분류하여 측방가압법으로 충전하였다. <1군: GP + AH-26, 2군: Resilon + RealSeal primer&sealant, 3군: Resilon + Rely-X Unicem 4군: Resilon + Biscem> 7일간 1% 메틸렌블루 용액에 침적 후 수직절단하여 치근첨부터 색소의 침투도를 측정하였다. 1군에서 가장 적은 미세누출값이 측정되었고, 2, 3, 4군 간의 통계적 유의성은 없었다. 이번 연구의 결과에 따르면, 자가-접착 레진시멘트는 Resilon을 이용한 근관충전시 sealer로 사용이 가능하리라 생각된다.

In this study, gall stones from 45 patients were analyzed in vitro. Gall stones from 23 patients were cholesterol stones and the others were non-cholesterol. Correlation with each radiologic physical properties(the number of stones, shape, calcification pattern, Hounsfield units measured by computed tomography) and chemical composition(cholesterol or non-cholesterol) were analyzed. The results revealed that the numbers and size were not related to the chemical composition, but there were significant correlation with faceted stones(p=0.002) or stones with no calcification (p=0.010) and cholesterol composition, and with irregular stones(p=0.000) or stones with dense calcification(p=0.015) and non-cholesterol composition. In study of Hounsfield units, it was difficult to fix the boundary, but the difference between cholesterol composition(138.43±281.81) and non-cholesterol composition(404.32±306.06)was significant(p=0.0109).

구강점막에 발생한 섬유성 과증식의 처치

함선영,송창규,박세희,김진우,조경모 大韓齒科保存學會 2009 Restorative Dentistry & Endodontics Vol.34 No.4

구강점막은 흡입되거나 압력을 받아, 병적이진 않으나 임상적으로 뚜렷한 변화를 일으키는 수많은 상황에 놓이게 된다. 협점막과 혀는 치아가 상실되었거나 여분의 공간이 존재하는 부위에서 돌기가 형성될 수 있다. 점막이 여분의 공간으로 압력을 받거나 흡입되어 섬유성 과증식이 발생하게 되는 것이다. 이번 증례보고에서는 구강점막의 섬유성 과증식의 처치에 대해 기술하고자 한다. 섬유성 과증식은 구강점막에 가해진 습관성 압력이나 흡입에 의해 형성될 수 있다. 섬유성 과증식의 치료는 단순 절제술과 원인을 제거하는 것이다. 또한 습관 조절이 재발을 방지하기 위한 중요한 요소가 된다. There are a number of situations where the oral mucosa can be sucked or pressed to produce relatively banal but clinical distinctive changes. The labial and buccal mucosa and tongue may develop protuberances in areas where a tooth is missing or extra space is present. The mucosa is pressed and sucked into theses paces, thus leading to the development of a fibrous hyperplasia. This case report describes the management of fibrous hyperplasia in oral mucosa. Fibrous hyperplasia can be formed by habitual pressure or suction in oral mucosa. Treatment of fibrous hyperplasia consists of simple excision and, if feasible, elimination of the cause. And habit control is a important factor for preventing recurrence.

게르마늄 내성 효모를 개발하여, 유기게르마늄을 생합성할 수 있는 최적의 조건을 알아보고, 게르마늄의 효모균체내에서의 생합성을 확인하였다. 1. 게르마늄 내성효모의 성장정도가 일반효모보다 약간 높은 것으로 나타났으며, 내성효모 배양액의 pH는 시간이 경과함에 따라 일반효모의 배양액보다 pH의 상승정도가 큰 것으로 나타났다. 2. 내성효모의 성장정도는 GeO2 의 농도가 90ppm까지는 점차 상승하다가 그 이상에서는 성장정도가 점차 감소하는 추세를 보였으나 일반효모보다는 감소하는 정도가 적은 것으로 나타났다. 3. 배지의 GeO2 농도를 80ppm으로 하고 pH를 8.0으로 조절한 후 30℃ 24시간동안 배양한 효모 중의 게르마늄의 농도가 0.818g/mg으로 가장 높게 나타났다. 4. 효모세포내의 게르마늄의 분포상태를 측정한 결과, 대부분의 게르마늄이 효모세포벽을 구성하는 고분자 다당체나 단백질에 결합된 것으로 추측된다. 또한 게르마늄의 일부는 수용성 단백질과 결합되어 있는 것을 확인할 수 있었다. A mutant of Saccharomyces cerevisiae ACTC 4105 was derived by a series of subcultures in the media containing increasing GeO_2 concentrations. The growth of tolerant yeast cells and the yield of organic germanium was studied as a function of GeO_2 concentrations, temperature and pH of media. The distribution of organic germanium in the tolerant yeast cells incubated in the media containing GeO_2 was also studied.

The main objective of this study is to reveal the relationship between the cause of a coach's job stress. In terms of the subject of this study, coaches, who are now at work in Kyunggi Province 2003, were selected as a population, especially 177 persons of coaches were adopted by means of nonproportional stratified sampling. In this survey, demographical variables are sex, age, education, job character, training item and coaching experience, in addition to them, with regard to dependent variables there are precisely not only role ambiguity, role conflict, excessive work, personal relations, expenses problem and work conditions as the cause of job stress, but also job satisfaction and tendency for turnover as the system efficiency. According to those kinds of method and procedure, the results of this study are as follows. 1) The difference of cause of job stress in sex is showed that male group is statistically more significant than female group. 2) The difference of cause of job stress in ages is present that group in forties is more significant than group of in twenties or thirties. 3) The difference of cause of education is significant only between group of the high school-educated and group of the graduate school-educated in terms of work conditions(p=0.0001). 4) The difference of cause of coaching experience is displayed that group of the 6-year-experienced over is much more significant than group of group of the 5-year-experienced below.
