Maxillofacial silicone elastomers are greatly affected by the presence of intrinsic and extrinsic pigmentation Objectives: The study aimed to evaluate the effect of the addition of TiO2 nanofiller and intrinsic pigment on the tear strength of Cosmesil M511 and VST50F silicone elastomers. Materials and Method: It comprised Cosmesil M511 and VST50F silicone elastomers. Each comprised of 20 samples. Each elastomers sample was further classified into 2 equal groups of 10 each. One group had no additives (control), C Heat-temper nature-vulcanizing HTV for the HTV elastomer and C RTV(room-temperature-vulcanizing) for the RTV silicone elastomers and the second group had nanofillers such as TiO2 and intrinsic pigment (experimental, E HTV for the HTV silicone elastomer and E RTV for the RTV silicone elastomers). In one part, tear strength and in another part Shore, A hardness was tested. Results: The mean tensile strength (kN/m) in C HTV was 11.6__ampersandsignplusmn; 0.12, in E HTV was 13.5__ampersandsignplusmn; 0.17, in C RTV was 24.4__ampersandsignplusmn; 0.13 and in E RTV was 27.6__ampersandsignplusmn; 0.16. The difference was significant (P__ampersandsignlt; 0.05). The mean hardness (Shore A unit) in C HTV was 25.2__ampersandsignplusmn; 0.13, in E HTV was 28.4__ampersandsignplusmn; 0.19, in C RTV was 27.8__ampersandsignplusmn; 0.07 and in E RTV was 28.6__ampersandsignplusmn; 0.14. The difference was significant (P__ampersandsignlt; 0.05). Conclusion: Authors found that both tear strength and hardness increased with the addition of nanofillers and intrinsic pigment.&#13;
