Abstract
Naturally available products have been used widely for centuries in handling human disease. The present study aimed to determine the effect of aluminum potassium sulfate addition into the soft liner on tensile strength and peel bond strength. The effect of aluminum potassium sulfate evaluated by two methods, first one include incorporation of KAL (SO4)2 into soft liner monomer in concentration (2%,3% by wt.) while the second method include immersion of soft liner specimens in solution of KAL(SO4)2 in concentration(5%,10% percent) during time periods (0,10 minutes). In conclusions, the results of current study encourage use KAL (SO4)2 within soft liner material
Highlights
Soft denture lining material used in patient suffering from pain or soreness resulting from tissue contact with hard denture base
Aluminum potassium sulfate(alum) having chemical formula KAL(SO4).12H20 and generally having no odor, no color sold crystal that return white in color in air that used in food preservation and water purification
Soft lining materials play a major role in prosthetic dentistry, due to the viscoelastic properties of denture liners which reduce and redistribute the functional load over the denture bearing area (13)
Summary
Soft denture lining material used in patient suffering from pain or soreness resulting from tissue contact with hard denture base. Addition of soft denture lining material ensuring optimal adaptation of the denture to the underling tissue. (1) Soft denture lining material characterized by high resiliency so acting as shock absorber reducing load transmission to the underling tissue. Soft liners are frequently used for patients who cannot bear wearing a conventional denture base (3). Aluminum potassium sulfate(alum) having chemical formula KAL(SO4).12H20 and generally having no odor , no color sold crystal that return white in color in air that used in food preservation and water purification. The alum has been recommended as active ingredient part in mouth wash by the Counter Advisory Panel of U.S Food and Drug Administration (FDAs) (4).
