Replacement resorption is followed by the delayed replantation of an avulsed tooth. Currently no effective treatment is substantiated for replacement resorption. The purpose of this study was to investigate the effect of stannous fluoride, bisphosphonate(etidronate disodium) and gallium nitrate, which have been shown to reduce dentin resorption, on human dentin. Osteoclasts were collected from tibeas of chich embryo. The cells were well agitated to prevent adhesion and seeded onto the sliced human dentin wafers which had been soaked in either culture media(control), or several different concentrations of stannous fluoride, etidronate disodium(1-hydroxyethylidene-1, 1-bisphosphonate disodium), and gallium nitrate. Resorption was measured by counting the number of resorptive pit produced by the cells. Results are ad follows. Stannous fluoride and etidronate disodium showed statistically significant reduction of dentin resorption(p<0.05) but the effect of stannous fluoride seemed to be its high cytotoxicity. Etidronate disodium did not show cytotoxicities in all experimented concentrations. Gallium nitrate did not show differences in resorption either between different concentrations of from the control group.

Background and Objectives : Digital rectal examination (DRE) and uroflowmetry have been usually together in the BPH management. The aim of this study was to determine whether DRE would affect uroflowmetry measurement. Materials and methods : A total of 80 male patients were included in this study. First uroflowmetry was done after DRE, second uroflowmetry was done without DRE. Third uroflowmetry was done after DRE, and fourth was done without DRE. Results : The mean Qmax on uroflowmetry after DRE was 15.2±8.7㎖/sec and 14.9±9.8㎖/sec. The mean Qmax on only uroflowmetry was 15.3±8.9㎖/sec and 15.4±8.4㎖/sec. There was statistically no difference between the mean Qmax(P> 0.05). And effect of digital rectal examination on uroflowmetry measurement with age was statistically no difference between the mean Qmax(P)0.05). Conclusions : We could not find and effect of DRE on uroflowmetry parameters, In this study, uroflowmetry test would be appropiate for recommending DRE before or after.

XML문서의 유사 태그 검색 시스템

Recently a new information searching method in Web is offered through XML that can make easily user's tags and make reference to theirs. But such a searching method has defects and submits inconvenience, because it only works when users input the perfectly correct tag and have to refer all possible searching words. Therefore, this paper presents an extended searching system which can search not only correct normal tags but also similar tags in order to reduce inconvenience that users have a difficulty in selecting a quest word. To search similar tags, we have created a thesaurus, that is designed with XML data and all advantages from writing sentences within XML. The existing XML text searching system operates only if the input tag is accurate, however, this extended searching system uses the thesaurus at tag searching, so it shows searched similar tags.

황규용,노병덕,김의성,이승종 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.1

정확한 근관장 측정은 성공적인 근관치료를 위해 필수적이다. Kuttler는 근관협착부는 주근단공에서 0.5 mm 상방에 위치한다고 하였고 Lee는 상아백악질경계점부위보다 주근단공이 재현성이 높고 임상적으로 관찰하기 용이하다고 보고하였다. 본 연구는 alginate model상에서 2개의 전자근관장측정기를 사용하여 얻은 측정치의 정확성(accuracy)을 평가하고 각각 0.5 mark와 Apex mark중에서 어느 지점에서 더 일관성(consistency)을 보이는지를 비교하고 또한 근관장을 측정할 때 파일을 전진시키면서 Apex mark를 측정한 값과 치근단부위를 지나친 후 다시 후퇴하면서 측정한 값의 차이를 비교하고자 하였다. 52개의 발거된 건전한 제 1, 2소구치를 대상으로 하였으며 Root ZX와 E-Magic Finder Deluxe를 이용하여 각각 26개중 13개는 파일을 전진하면서 0.5 mark에서 근관장을 측정하고 Apex mark에서 근관장을 측정한 후 0.5 mark에서 고정하였다. 나머지 13개는 0.5 mark에서 근관장을 측정한 후 Apex mark에서 근관장을 측정하고 다시 치근단 부위를 넘어선 후 후퇴하면서 Apex mark에서 근관장을 측정하고 고정한 후 치근단부 4 mm를 삭제하여 현미경상에서 파일 끝부터 주근단공까지의 거리를 측정하였다. 그 결과 Root ZX와 E-Magic Finder 모두, 실험군 100%에서 주근단공과 file tip간의 거리가 임상적 허용범위인 ± 0.5 mm 내에 있었으며 0.5 mark보다 Apex mark에서 더 높은 일관성을 보였다. 주근단공에서 file tip 사이의 거리는 Root ZX의 0.5 mark에서 -0.18 mm, Apex mark에서 -0.07 mm 이고 E-Magic Finder의 0.5 mark에서 -0.25 mm, Apex mark에서 -0.02 mm를 나타내었다. Apex band는 0.04 mm였다. 따라서 Alginate model을 사용한 본 실험조건에서는 Apex mark에서 근관장을 측정한 결과 거의 주근단공과 일치하고 다른 여러 연구에서 주근단공에서 0.5 mm 상방에 근관협착부가 위치한다고 보고하였으므로 임상적인 측면에서 Apex mark에서 측정한 근관장에서 0.5 mm 를 빼서 근관장으로 사용하는 것이 임상적으로 더 좋으리라고 사료된다. The purpose of this study was to evaluate the consistency of two electronic apex locators in vitro model. Materials consisted of fifty two extracted premolars and two electronic apex locators: Root ZX (J.Morita. Osaka, Japan) and E-Magic Finder Deluxe (S-Denti, Cheonan, Korea). After access preparation, the teeth were embedded in a saline-mixed alginate model. Canal lengths of each tooth were measured at "0.5" and "Apex" mark of the apex locators, respectively so that each tooth had two measurements from 0.5 and Apex points. The file was fixed at final measurement using a glass ionomer cement. The apical 4 mm from the apex was exposed to measure the distance from the file tip to the major apical foramen of each tooth. Average distances and standard deviations were used to evaluate the consistency. Results showed that all measurements of both Root ZX and E-Magic Finder located the major foramen the range of ± 0.5 mm level. Both apex locators showed better consistency at Apex mark than at 0.5 mark. The average distance of file tip-major foramen was - 0.18 mm at 0.5 mark and - 0.07 mm at Apex mark in Root ZX, - 0.25 mm at 0.5 mark and - 0.02 mm at Apex mark in E-Magic Finder. Standard deviation was 0.21 at 0.5 mark and 0.12 at Apex mark in Root ZX, 0.12 at 0.5 mark and 0.09 at Apex mark in E-Magic Finder.

Background and Objectives: It is crucial to understand the exact public health burden of out-of-hospital cardiac arrest (OHCA) cases; this is presently unknown since sufficient episodes are not reported in registry studies. We aimed to evaluate the epidemiologic features and outcomes of non-traumatic OHCA. Methods: During January 2008 to December 2017, we enrolled 387,665 patients who had been assigned a code for sudden cardiac arrest or had undergone cardiopulmonary resuscitation in the emergency room using the Korean National Health Insurance Service database. Those whose arrest was of non-cardiac origin were excluded. Results: The incidence of OHCA per 100,000 patients increased steadily from 48.2 in 2008 to, 53.8 in 2011, 60.1 in 2014, and 66.7 in 2017, with a 1-year survival rate of 8.2%. Age and sex-adjusted mortality rates showed a decreasing trend. The hazard ratio was 1.0015 in 2009, 0.9865 in 2012, 0.9769 in 2015, and 0.9629 in 2017 (p for trend <0.0001), with coronary artery disease-related OHCA accounting for 59.8% of the total. Subgroups with coronary artery disease-related OHCA were more likely to be older and have a higher prevalence of all related comorbidities, excluding malignancy, than those with non-coronary artery disease-related OHCA. Conclusions: This nationwide population-based study showed that the incidence of OHCA in Korea had increased during the last decade. The post OHCA 1-year mortality rate showed a poor outcome but improved gradually.
