Background The proportion of elderly individuals with detachable partial dentures is rising. The frequency of root caries and gingival recession are both rising concurrently. Fluoride can be delivered into the oral cavity through several different means, including topical fluoride, fluoridated mouthwash, dentifrices, and fluoride-releasing restorative materials. Objectives To determine the effect of PMMA heat-cured resin materials in terms of color change and porosity by the addition of aluminum fluoridated salt. Materials and Methods A study sample of sixty specimens was fabricated following the ADA specification No.12, 1999. Depending on the type of the testing measurements, they were split into two main groups (color change and porosity).T-hese two groups were - subgrouped based on the aluminum fluoride percentage (control group0%; 2%, and 5%). ( n=10). All specimens were tested after being submerged in artificial saliva for two months. Study data were analysed using the Games Howell and LSD test at a significant p-value of (P<0.001). Results The Games Howell and LSD test indicated highly significant differences in the color changes of heat-cured PMMA after incorporation with aluminium fluoride (P<0.001). Also, there was a significant difference in the porosity of heat-cured acrylic resin material after incorporation with aluminium fluoride (P<0.001). Conclusion The color changes of heat-cured PMMA increased after incorporation with 2% and 5% aluminium fluoride, while the porosity was slightly increased after incorporation with aluminum fluoride.
