OBJECTIVE To determine in vitro antibacterial activity of commercially available skin, wound, and skin/wound cleansers at cell-safe (nontoxic) concentrations. DESIGN Saline and 19 other commercial wound and skin cleansers were evaluated for cytotoxic effects on mouse dermal fibroblasts. Cells were exposed to serial 10-fold dilutions of each cleanser until treatment-induced cytotoxicity was co...

Polyhexamethylene biguanide (PHMB; CAS no. 2875743-3) is a preservative used as a biocide in industrial products (e.g. swimming pool disinfectants), medical devices (e.g. wound cleansers), contact lens solutions, and cosmetics such as wet wipes, deodorants, and facial cleansers. It is considered to be a rare contact allergen, with a sensitization rate of ∼0.5% in an unselected population (1, 2)...

The relation between the bonding efficacy of the dentin adhesive and the physical change of the dentin after treatment with various dentin cleansers was investigated. The dentin surface was cleaned with one of the seven experimental dentin cleansers, 5, 10, 20, 30 and 40% of the phosphoric acid, neutralized 0.5 M EDTA solution (pH 7.4) and 9.1% pyruvic acid containing 9.1% glycine, prior to the...

Denture-induced stomatitis in children was studied microbiologically. Quantitative cultural studies on Candida and bacteria were done in 17 denture wearers with or without palatal denture-induced stomatitis (erythema score 0-3) and in 16 healthy nondenture wearers. It was found that significantly higher numbers of Candida both in denture plaque and in saliva were cultured from the denture weare...

Purpose: Some patients experience adverse reactions to poly(methyl methacrylate)-based (PMMA) dentures. Polyamide (PA) as an alternative to PMMA has, however, not been well documented with regard to water sorption and water solubility. The aim of this in vitro study was to measure water sorption and water solubility of two PA materials compared with PMMA, and to evaluate the major components re...

The relatlon between the bonding eMcacy ef the dentin adhesive and the physical change of the dentin after treatment with various dentin cleansers was investigated, The dentin surface was cleaned with one of the seven experimental dentin cleansers, 5, 10, 20, 30 and 40% of the phosphoric acid, neutralized O,5M EDTA solution (pH7.4) and 9.1% pyruvic acid containing 9,1% glycin, prior to the comb...
