بررسی چسبندگی کاندیدا آلبیکنس به دو نوع مختلف رزین آکریلی. (Persian)

Background and Aim A common infection in complete or partial dentures is denture stomatitis. One of the most important factors in the adhesion of Candida albicans is the surface and chemical properties of the denture base materials. This study aims to evaluate the surface roughness and adhesion of Candida albicans to two different types of acrylic materials (Vertex and Ivoclar). Methods & MaterialsIn this experimental study, 16 samples were prepared from each Vertex and Ivoclar acrylic resin. The surface roughness of the samples was measured by a profilometer. The samples were then placed in a cell suspension of Candida albicans. After incubation and staining with acridine orange, the yeast cells attached to the acrylic samples were counted using a fluorescent microscope. Data were statistically analyzed by t-test. Ethical Considerations This study was approved by the ethics committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1398.301) Results There was no statistically significant difference in the mean surface roughness between the two study groups (P=0.311). However, Candida albicans colonization in ivoclar acrylic was significantly lower than in vertex acrylic (P=0.000). Conclusion Differences in surface topography and physical and chemical properties of Vertex and Ivoclar acrylic resin affect the adhesion of Candida albicans. [ABSTRACT FROM AUTHOR]
