In recent years, software infrastructures for the run-time instrumentation of programs have begun to emerge. This paper presents and evaluates prototypes of dynamic instrumentation and dynamic control of instrumentation for parallel mixed MPI/OpenMP applications. An overview of the technology behind these approaches is presented. Prototypes of dynamic instrumentation and dynamic control of inst...

OBJECTIVE The purpose of this study was to evaluate the root surface roughness after instrumentation with hand curette and diamond-coated sonic and universal ultrasonic tips. MATERIALS AND METHODS Forty root surfaces of human teeth were randomly assigned to four treatment groups: control group (without instrumentation), curette instrumentation, ultrasonic instrumentation with universal tip an...

introduction: pulpectomy of primary teeth is commonly carried out with hand files and broaches; a tricky and time consuming procedure. the purpose of this in vitro study was to compare the cleaning efficacy and time taken for instrumentation of deciduous molars using hand k-files and flex master rotary system. materials and methods: in this study, 68 canals of 23 extracted primary molars with a...

introduction: the aim of this study was to evaluate the amount of dentine removed after canal preparation using stainless steel (ss) hand instruments or rotary profile instruments. materials and methods: thirty-six extracted human teeth with root canal curvatures less than 30º were embedded in clear polyester resin. the roots were cut horizontally at apical 2, 4 and 7 mm. dentin thickness was m...

background and aims. during root canal preparation, debris extruded beyond the apical foramen may result in periapical inflammation and postoperative pain. to date no root canal preparation method has been developed that extrudes no periapical debris. the purpose of this study was to identify a system leading to minimal extrusion of debris from the apical foramen. the study was conducted to com...
