Abstract

Denture plaque is an important factor in the pathogenesis of denture stomatitis. Denture cleanliness is essential to prevent accumulation of plaque with its deleterious effects on the mucosa. With emphasis on patient education and preventive dentistry, a dentist must be able to recommend a denture cleanser that is effective, non deleterious to denture materials, and safe for patient use. A two part study was designed to compare the efficacy of three chemical denture cleansers (Polident, Sodium hypochlorite and vinegar) in removing and/or killing aerobic, anaerobic and yeasts cells on the dentures. In the present investigation, ten upper completedentures worn by 53-75 years of age patients were used. The dentures were placed in the mixture of strile D.W. and antibacterial agents (Polident, Naclo, Vinegar) for certain period of time and then examed for the presence of bacteria and candida albicans. The following conclusions were obtained in this study:1. Polident was the most effective sanitizing agent.2. Sodium hypochlorite and Vinegar were effective in killing bacterial but less effective on candida albicans.Key words: Denture cleanserMicroorganismCandida albicans
