ABSTRACT

Objectives: The influence of different denture base resin materials on the oral flora and supporting structures was studied extensively. These materials can be used for patients with irregular or resorbed ridges, as well as,thin and non resilient mucosal tissues ridges. They can be used in cases of bruxism, xerostomia, in dentures opposing natural teeth, patients who may not tolerate conventional hard denture bases and for geriatric patients. Abundance of microbial flora is affected by the surface texture and roughness of the fitting surfaces of the complete denture, and their occurrence percentage are related to different denture base resin. Purpose: The present study evaluates candida albicans proliferation with complete dentures made of different denture base materials. Materials and methods: Thirty patients received complete dentures divided into three groups, Group A applied complete dentures constructed with heat-cured acrylic resin, Group B applied complete dentures constructed with soft acrylic denture flanges and base) and Group C has complete dentures with casted metal bases. The follow-up period was four weeks for all groups. Results: Significant differences were detected in the colony counts between the different base materials during the follow up period. Conclusion: patients utilizing complete dentures constructed with metallic denture base showed to be effective in decreasing the fungal growth typically present in complete dentures. Even though overt clinical manifestations were not present, colony counts of Candida species were high in the acrylic resin denture bases of these patients. This investigation demonstrated that metal base complete dentures provide an important alternative dental provision for edentulous and other patients who are particularly prone to higher incidences of fungal infections. moreover, more contentment and comfortability of patients utilizing soft acrylic resin denture bases were reported.
