OBJECTIVE To compare the efficacy and safety of ultrasonic surgical instrumentation with nonultrasonic traditional surgical techniques in various types of surgery. DATA SOURCES Electronic searches of MEDLINE, Current Contents, and the Cochrane Library were performed for the period of 1990 to June 1, 2005, using relevant search terms. A manual check of all references in accepted studies was al...

A commercial kit for the manual quantification of slight albuminuria by immunoturbidimetry (“AlbuSure-Qnt”; Cambridge Life Sciences, Cambridge, U.K.) has been adapted for use on the “Multistat 3 Plus” centrifugal analyzer (Instrumentation Laboratory). Standards with concentrations of 0, 10.3, 19.0, 40.0, 79.0, and 165 mgfL are supplied ready for use. Antiserum is diluted with buffer in the rati...

Background : The purpose of this study was to evaluate apical debris extrusion in curved root canals using a specific file system.METHODS:50 human mandibular molars were extracted and chosen for the study, ranging between 20 40 degree curvature radii <10mm randomly assigned 2 groups (n=20) according kinematics used canal preparation ( reciprocating motion with waveone gold system) Manual Tec...

In effort to reduce the revision burden of total knee arthroplasty (TKA), industry emphasis has focused on replacing manual techniques-which are subject to variability-with technological implements. Unfortunately, technological innovation often continues before adequate time for critical evaluation has passed. Therefore, the purpose of this descriptive literature review was to collect a large s...

Accurate placing of securely tied knots in laparoscopic surgery is technically demanding and time consuming. Surgeons must face difficulties arising from 2-dimensional vision, spatial limitations, and restricted movement. Issues to be taken into account include security, virtuosity, and cost effectiveness. The authors believe that in spite of advances in instrumentation and optics, training sho...
