ABSTRACT Over the years researchers have reported on the frequency and distribution of yeast in the oropharynx of apparently normal individuals and those with systemic or mycotic diseases wearing dentures. Few workers have taken into consideration the role played by the legion of denture base materials on the occurrence and progression of denture stomatitis. Hence this study was undertaken with the objective of evaluating the in vitro adherence of Candida albicans to different denture base materials namely reinforced polymethyl methacrylate, Nonreinforced polymethyl methacrylate and Cobalt chrome alloy of which chrome cobalt alloy showed less adherence to candidal cells compared to the two polymethyl methacrylate resins.

Powder Component

There has been little change in the formulation of bone cements since Sir John Charnley first developed them in the 1970s. Bone cements are methacrylate based systems packaged in two components [1]. The powder component contains a mixture of polymethyl methacrylate (PMMA), methyl methacrylate-styrene-copolymer, and a radio opacifier (either barium sulfate or zirconium oxide) [2]. The second component is a liquid monomer typically containing methyl methacrylate, N, N-dimethyl-p-toluidine (activator), and hydroquinone. Flexural strength and flexural modulus of bone cements range between 60–75 MPa and 2.2–3.3 GPa, respectively [3, 4]. ISO 5833 requires bone cements to have a strength greater than 50 MPa and a modulus greater than 1.8 GPa [5].
