OBJECTIVES The aim of this randomized, controlled, prospective clinical study was to evaluate patients' intraoperative discomfort during root canal preparations in which either multi-file rotary (Mtwo) or single-file reciprocating (Reciproc) systems were used. MATERIALS AND METHODS Fifty-five adult patients, aged between 25 and 69 years old, with irreversible pulpitis or pulp necrosis partici...

This paper presents the use of the Linking File System as infrastructure for software evolution research. The addition of richer metadata in links and attributes makes LiFS an alternative to conventional approaches to storage for that purpose. We pursue our approach through the instrumentation of Kenyon and a case study that involves the correlation of Bugzilla data and CVS histories. Further i...

Monitoring is at the heart of cluster management. Instrumentation data is used to schedule tasks, load-balance devices and services, notify administrators of hardware and software failures, and generally monitor the health and usage of a system. The information used to perform these operations must be gathered from the cluster without impacting performance. This paper discusses some of the perf...

OBJECTIVE The aim of this study was to compare the fracture strength of roots instrumented with three different single file rotary systems in curved mesial root canals of maxillary molars. MATERIALS AND METHODS Curvatures of 25°-35° on mesial roots of 60 maxillary molar teeth were sectioned below the cementoenamel junction to obtain roots 11 mm in length. The roots were balanced with respect ...

introduction: the aim of this study was to compare the dentine removing efficacy of gates-glidden drills with hand files, protaper and oneshape single-instrument system using cone-beam computed tomography (cbct). methods and materials: a total of 39 extracted bifurcated maxillary first premolars were divided into 3 groups ( n =13) and were prepared using either gates-glidden drills and hand ins...

This clinical trial focused on collating the instrumentation time and quality of root canal obturation in primary molars treated with three techniques: adaptive, rotary, manual. A triple-armed, randomized controlled was performed 75 requiring pulpectomy treatment, divided into groups (n = 25 per group). The teeth Group 1 were instrumented an adaptive technique (XP-endo Shaper, FKG Dentaire, La ...

Current improvements in nickel-titanium (Ni-Ti) rotary file systems have created a paradigm shift the root canal therapy of primary teeth. Therefore, it is necessary to perform comprehensive evaluation regarding efficiencies newly manufactured instruments for different parameters. The current study was conducted evaluate abilities RaceEvo, R-Motion, ProTaper Gold (PTG) curved canals with regard...

AIM To evaluate and compare the efficacy, cleaning ability of hand and two rotary systems in root canal retreatment. METHODOLOGY Sixty extracted premolars were retreated with following systems: Group -ProTaper Universal retreatment files, Group 2-ProFile system, Group 3-H-file. Specimens were split longitudinally and amount of remaining gutta-percha on the canal walls was assessed using direc...
