STATEMENT OF PROBLEM Color stability is an important property of denture base acrylic resin. Color changes indicate aging or damaged dental materials. However, little information is available on the influence of denture cleansers on the color stability of acrylic resins. PURPOSE The purpose of this study was to determine the influence of denture cleansers(More)
The dimensional accuracy of rectangular acrylic resin specimens was examined when they were processed by three methods: a conventional method, the SR-Ivocap system, and a microwave curing method. The dimensional accuracy was evaluated by the change of the distance vector V, which is calculated by means of measurements of the distances between fixed points(More)
The quantity of residual monomer content in 24 maxillary dentures was detected by gas liquid chromatography. The residual monomer contents tended to be lower in dentures used for long periods than in those used for short periods. Decreases in the quantities of residual monomer in acrylic resin dentures as a result of aging can be expressed in a hyperbola.(More)
A previous study suggested that denture plaque played an etiologic role in denture stomatitis. In daily practice, it is important to instruct denture wearers about denture plaque control. In this study, the major areas of investigation were the degree of denture stomatitis and denture plaque, denture hygiene habits, wearing habits and age of present(More)
The nature of the physicochemical forces involved in the adherence of Candida species to a solid surface was investigated using modified glass slides. It was found that hydrophobic yeasts adhered to hydrophobic surfaces mainly by hydrophobic interactions, whereas in less hydrophobic yeasts electrostatic interactions seemed to play a more important role in(More)
The biofilm formation of the oral fungal pathogen Candida on denture acrylic strips coated with saliva, serum and, saliva-serum pellicle were examined in vitro using Candida albicans (four isolates), Candida glabrata (three isolates) and Candida tropicalis (three isolates). The degree of biofilm activity varied depending upon both the isolate and the(More)
OBJECTIVES The purpose of the study was to examine and describe the deformation behaviour of five denture soft lining materials under dynamic cyclic loading over a range of applied forces using apparatus designed to simulate masticatory performance. METHODS Five lining materials were tested over 5-min periods using an Instron tensile testing machine that(More)
