OBJECTIVE To determine if improvement in patients' metered dose inhaler (MDI) technique could be achieved in the emergency department (ED) with the use of a simple illustrated instruction sheet. METHODS Prospective evaluation of a convenience sample of patients with asthma or COPD. Patients were first subjectively and objectively evaluated on their usual MDI technique, then were given an illu...

introduction: many studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. the aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method. materials and methods: nine blocks of psm-5 photoelastic material with 45×45×10 mm dimen...

This paper investigates some mechanical aspects of a new endodontic restoration technique, based on the idea that the root cavity can be more efficiently filled if multiple prefabricated composite posts (PCP) are employed. Multi-post technique increases bearing capacity and durability of endodontically treated teeth, as shown by numerical simulations performed through three-dimensional elastic ...

OBJECTIVES The aim of this retrospective, longitudinal study was to examine the survival time of custom-fabricated, cast post and cores and to evaluate, which covariates influence the risk of failures over a period of up to 10 years based on a large patient collective. METHODS The files of 565 patients, who had been fitted with a total of 802 custom-fabricated, cast post and cores using a sta...

Background: To study and compare the effectiveness of active release technique and mulligan bent leg raise in subjects with hamstring tightness. Methods: 40 normal healthy subjects (20 in each group) were recruited in the study under simple randomization method. Group A received single session of Active Release Technique and Group B received single session of Mulligan Bent Leg Raise technique f...
