1. Abstract This paper presents the features of Instrumentation Amplifier for biomedical applications. This Instrumentation Amplifier is a device created from Operational Tran conductance Amplifier. It is designed to have input high impedance , output low impedance, low DC offset, low noise , high common mode rejection ratio and high power supply rejection ratio. The circuit has been integrated...

The objective of the study was to evaluate the bacteria extruded apically during root canal preparation using hand and two rotary instrumentation techniques. The method include eighty freshly extracted mandibular premolars were mounted in bacteria collection apparatus. Root canals were contaminated with the pure culture of Enterococcus faecalis (ATCC 29212) and dried at 37 0 c for 24 hour. Then...

Currently, various Nickel-Titanium rotary files are used in endodontic treatment, but there is no one perfect system that can be applied to any clinical situation. Therefore, the combined uses of various file systems which can emphasize the advantages of each system are introduced as hybrid instrumentation. The ProTaper system is efficient in body shaping and apical pre-enlargement but is repor...

Objective: The aim of this study was to compare the amounts debris extruded apically with use different single file systems during endodontic retreatment. Material and Methods: 36 mandibular premolar teeth were prepared ProTaper Universal files up F3. At every instrument change, root canals irrigated 2 mL 5.25% NaOCl solution. After canal preparation, final irrigation performed using 5 17% EDTA...

The fourth version of Symbiotic brings a brand new instrumentation part, which can now instrument the analyzed program with code pieces checking various specification properties. As a consequence, Symbiotic 4 participates for the first time also in categories focused on memory safety. Further, we have ported both Symbiotic and Klee to llvm 3.8 and added new features to the slicer which is now m...

Introduction The present in vitro study aimed to evaluate and compare the changes in shape and surface area of the major foramen following shaping of curved canals with three new generation NiTi engine-driven instruments naming ProTaper Next, BT RaCe and WaveOne Gold- with 3 different levels of protrusion beyond the major apical foramen. Methods and Materials A total of 45 extracted human mol...
