A comparative study of cyclic fatigue of 6 endodontic systems. An study.

Background: Mechanical preparation and the formation of space for adequate obturation are included in root canal shaping, but the complex root canal anatomy may be affect it. Manufacturers have created different alloys like M-Wire, Blue-Wire, Gold-Wire or R-phase. Objective: This investigation was performed to verify the null hypothesis that there were not significant differences between size 25 instruments ESP Files Thermoflex, Protaper Ultimate, Protaper Next, Blueshaper, One Curve and 2Shape about cyclic fatigue and length of broken fragments.

Applicability of Outpatient Quality Indicators for Appropriate Antibiotic Use in a Primary Health Care Area: a Point Prevalence Survey.

The ability to measure the quality of antibiotic prescriptions is a critical element in all antimicrobial stewardship programs. The aims of the present study were to evaluate the clinimetric properties of 32 recently developed outpatient quality indicators (OQIs) and to identify potential room for improvement in antibiotic use in a primary health care (PHC) area. The study was performed in a PHC area in Barcelona, Spain with 260,657 inhabitants, nine PHC centers, and a 400-bed acute-care teaching hospital.
