| Popis: | Objective This study aimed to evaluate the effects of disinfectant solutions, namely, the alcoholic extract of Salvadora persica L. (A1 = 10% and A2 = 15%) and chlorhexidine digluconate (A3 = 2%), on the tear strength and hardness of room temperature vulcanizing (RTV) VST50F and heat temperature vulcanizing (HTV) Cosmesil M511 silicone elastomers before and after reinforcement with nanofillers (TiO2) and intrinsic pigment. Materials and Methods: A total of 320 specimens were prepared, with 160 specimens each for RTV and HTV silicone. Forty specimens were evaluated before disinfection and divided into two equal groups, namely, control (without additive) and experimental (with additive) groups, for tear strength and hardness tests. The 120 specimens were divided into three equal groups, with two equal subdivisions for tear strength and hardness tests, and were evaluated after disinfection. ANOVA and Tukey's honest significant difference tests were conducted for group comparisons (significance level set at P |
