title: Comparison of the effectiveness of several denture sanitizing systems: a clinical study.
abstract: The purpose of this clinical study was to test the effectiveness of three methods of decontamination on complete dentures. Dentures worn by patients for varying lengths of time were handled aseptically and treated with three different treatment modalities. The dentures were touched and sectioned and then retouched to a variety of microbiological media. The quantity of microbial growth was recorded and predominating microorganisms were identified using standard microbiological techniques. System A was found to consistently decontaminate and sanitize dentures worn by patients. System B and System C showed variable reduction of microorganisms. An unexpected spectrum of both pathogenic and opportunistic microorganisms was found in the dentures examined, including a wide range of gram-negative bacteria, gram-positive bacteria, and yeasts. A wide range of microorganisms must be considered when treating either oral or systemic diseases in denture wearers. Denture hygiene and decontamination are critical to the prevention of oral and systemic disease transmission. The dentures of ill patients must be considered as possible sources of pathogenic microorganisms.
