- Abstract
Background: - Soft liners placed in dentures have been used as carrier for antifungal drugs in treating denture stomatitis. The aim of this study is to evaluate the effect of incorporated of silver nitrate in different volume into acrylic soft denture liner and to assessment the effect of these additions on some mechanical properties. Materials and methods: One hundred and twenty (120) specimens were prepared from heat cure soft liner material and divided into three groups according to the test that carried out. Forty specimens for each (hardnesstest, compressive strength test, water sorption and solubility test). Then each test subdivided into four subgroups according to the volume of the silver nitrate solutionincorporation. Controlgroup which have ten specimens without incorporation of silver nitrate and experimental groups which have thirty specimens with incorporation of (0.05 ml, 0.1 ml and 0.2 ml) of silver nitrate solution. All specimens were constructed as in conventional method then stored in distilled water for seven days be ready for measurement. Findings: - The results of this study showed that highly significant increase in the hardness tested groups also compressive strength group at 0.1 ml of silver nitrate incorporation while significant decrease in 0.05 and 0.2 ml groups. Watersorption and solubility showed that highly significant increase in all volumes of silver nitrate incorporation groups. Conclusions: - Silver nitrate incorporation was significantly increases the hardness of soft lining material while Compressive strength was significantlyincreased after incorporation of 0.1 ml of silver nitrate. The incorporation of 0.05 and 0.2 ml of silver nitrate to soft liner material significantly was decreased. Regarding water sorption and solubility were significantly increased after incorporationof silver nitrate to soft lining material in all experimental groups.
