| Background: One of the primary applications for thermoplastics flexible resins involved flexible partial dentures tooth born and combination flexible and chromium cobalt framework partial denture. There are certain to be many new clinical applications for thermoplastic resins in dentistry. The cleansers effect maturity of the sterilization of acrylic resin denture base; therefore, it using chemical or physical methods can minimize the risk of periodontal disease such as denture related stomatitis in denture users. This study aims: to evaluate of the effect of hypochlorite cleanser on the water sorptsion and solubility of flexible and conventional hot – cure acrylic resin denture base. Compare the results on the water sorption and solubility between specimens. Methods: Sixty of flexible and hot –cured acrylic resin specimens were prepared as following: 30 samples from hot – cure acrylic divided into two group 15 specimens immerse in the hypochlorite and 15 specimens immerse in the water. The process is cured in the water bath according to the conventional method. 30 specimens from flexible resin divided into two group 15 specimens immerse in the hypochlorite and 15 specimens immerse in the water. The process is cured in the plastic injection machine. Results: showed highly significant differences among these groups. It showed that the hot – cured acrylic high water sorption and lower solubility and the flexible resin lower water sorption and high solubility. Conclusion: 1. The comparison between the hot –cured acrylic and flexible resin denture base immersed in the hypochlorite and water on the water sorption is higher of the hot –cure acrylic and lower of the flexible resin. 2. The flexible resin denture base immersed in the hypochlorite and water is higher solubility compared with the hot –cured acrylic is lower solubility. | ||
