Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 3
Abstract
To evaluate the residual disinfectant remained after disinfection of different denture base materials. Sixty samples are taken (n=30) each of heat cute and Self cure denture base resins and immersed in three differentcommonly available disinfectant solutions for 1 day and 7 days. Residual disinfectant remained is measured with UV spectrophotometer.Aim: To evaluate the residual disinfectant remained after disinfection of different denture base resin materials.Materials & methodology: Sixty samples are taken (n=30) each of heat cure and Self cure denture base resin materials. Samples are sub divided into 3 sub-groups based on disinfectants. Three most commonly used disinfectants are chosen, which are 2% glutaraldehyde, 2% chlorhexidine,1% sodium hypochlorite.The specimens were produced in molds prepared by the investment of stainless-steel dies of 30 mm diameter and 3.0 mm width. With an ISO standardization number ISO/DIS 1567. Specimens are placed in each 100 ml of three different disinfection solutions. Specimens are stored for 1 day and 7 days. The testing was done with UV-Visible spectrophotometer. Results: It was shown that more leaching is seen with sodium hypochlorite, after one day than after days followed by chlorhexidine and glutaraldehyde.Conclusion:The amount of residual disinfectant was found more in Self cure resins when compared to heat cure resins. And it was found more after 1day than 7 days when immersed in disinfectant solutions. The amount residual disinfectant was found to be more with sodium hypochlorite followed by chlorhexidine and least with glutaraldehyde.
