The effect of the antimicrobial additives benzalkonium chloride and cetylpyridinium chloride on a restorative glass-ionomer dental cement (Fuji IX) has been studied. Both substances were added to the glassionomer at levels of 1%, 2% and 3% by mass at the mixing stage, and various effects were studied. Setting time was altered in most cases, but only slightly. Compressive strength and release we...

PURPOSE Antiseptic mouth rinses are widely recommended and marketed to improve oral health. This article summarizes current studies on the comparative effectiveness of selected antiseptic mouth rinses in controlling plaque and gingivitis, as well as risks associated with daily exposure, including salivary flow rate, oral cancer and wear of composite restorations. METHODS Electronic database ...

This work follows from that of Blumberg & Ogston (1957). They showed that papain is a specific agent for degrading the protein part of the hyaluronic acid complex isolated from ox synovial fluid by filtration (Ogston & Stanier, 1950), and that when this protein is degraded marked changes in the non-Newtonian viscosity occur. This is associated with a marked decrease in the molecular weight and ...

The aim of this in vitro study was to determine the maximum inhibitory dilution (MID) of four cetylpyridinium chloride (CPC)-based mouthwashes: CPC+Propolis, CPC+Malva, CPC+Eucaliptol+Juá+Romã+Propolis (Natural Honey) and CPC (Cepacol), against 28 Staphylococcus aureus field strains, using the agar dilution method. Decimal dilutions ranging from 1/10 to 1/655,360 were prepared and added to Muel...

The behaviour of a cetylpyridinium chloride/sodium salicylate wormlike micellar system undergoing capillary breakup is investigated experimentally. The transient elongational flow induced in a thinning thread is used to study the apparent viscosity and effective relaxation time of the micellar network in extension. The sensitivity of the material response to initial conditions and deformation h...
