objective: reinforcement with fiber is an effective method for considerable improvement in flexural properties of indirect composite resin restorations. the aim of this in-vitro study was to compare the transverse strength of composite resin bars reinforced with preimpregnated and non-impregnated fibers. materials and methods: thirty six bar type composite resin specimens (3×2×25 mm) were const...

BACKGROUND The use of antimicrobial-impregnated central venous catheters (CVCs) for the prevention of CVC microbial colonization and catheter-related bloodstream infection (CRBSI) remains controversial. METHODS We performed a meta-analysis of randomized controlled trials (RCTs) evaluating CRBSI and colonization of CVCs impregnated with rifampicin-based antimicrobial combinations. Our main ana...

This study investigated the feasibility of using an electron beam (EB) process to cure chemically impregnated wood products. Maple wood planks were impregnated with the low-viscosity resins 1,6 hexanediol dimethacrylate (HDDA) and trimethylolpropane trimethacrylate (TMPTA). The addition of nanoparticles into the formulation was also studied. The impregnated wood was then cured by EB irradiation...

Two stage total hip arthroplasty revision surgery includes foreign material debridment, insertion of antibiotic impregnatedcement spacer, and finally, reimplantation of the prosthesis. This review has aimed to evaluate the efficacy of antibioticimpregnated cement spacers in infection control and eradication in arthroplasties.A total of 85 articles on total hip arthroplasty wer...

evidence acquisition electronic medical data bases (including pubmed and scopus) from first of january 1975 to 30th of july 2015 were searched. the key words used for the relevant articles search were catheter, venous, prevention, impregnated, bloodstream, chlorhexidine-silver sulfadiazine, rifampicin-minocycline, and rifampicin-miconazole. this review focuses on the evidence on the efficacy an...

The aim of this study was to compare the in vitro activity and the impact on bacterial adhesion of two different catheters, one impregnated with chlorhexidine-silver sulfadiazine (C-SS) and the other not impregnated with antibacterial agents. The antimicrobial coating prevented the bacterial colonization by slime positive Staphylococcus epidermidis in the first two days. The antibacterial activ...

BACKGROUND Impregnated central venous catheters are recommended for adults to reduce bloodstream infections but not for children because there is not enough evidence to prove they are effective. We aimed to assess the effectiveness of any type of impregnation (antibiotic or heparin) compared with standard central venous catheters to prevent bloodstream infections in children needing intensive c...

Background: Some researchers claim that permethrin-impregnated clothes are effective in the prevention of cutaneous leishmaniasis. Objectives: To determine the effectiveness of permethrin-impregnated clothes in the prevention of cutaneous leishmaniasis. Patients and Methods: 272 soldiers were randomized in two groups. In one group permethrin-impregnated clothes and in the other group, control c...

PURPOSE To evaluate microbial contamination in silver-impregnated contact lens (CL) storage cases while establishing the effect of "wet " and "dry " case maintenance and to determine its association with clinical signs, symptoms, and compliance. METHODS Two noncontemporaneous prospective studies were conducted. Regular storage cases in study 1 (n = 40) and silver-impregnated cases in study 2 ...

background and aims. the mechanical properties of fiber-reinforced composite fixed partial dentures (fpds) are affected by fiber impregnation. the aim of this in vitro study was to compare the fracture resistance of composite fixed partial dentures reinforced with pre-impregnated and non-impregnated fibers. materials and methods. groups (n=5) of three-unit fiber-reinforced composite fpds (23 mm...
