Implication

Randomized trial evaluates nanosilica's effect on tear strength and color stability in facial silicones, suggesting improvements in clinical performance.

Key Points

  • This study aims to evaluate how nanosilica fillers and pigmentation affect the mechanical properties and color stability of RTV silicone materials.
  • Fifty P25 silicone samples were analyzed with varying nanosilica concentrations (0%, 1%, 2%, 3%, 6%) and TiO2 pigments.
  • Tear strength was measured using a universal testing machine.
  • Color stability was assessed under accelerated aging conditions using the CIE Laboratory method.
  • The tear strength decreased from 18.984 kN/m (0% nanosilica) to 6.446 kN/m (6% nanosilica).
  • The 2% nanosilica group demonstrated superior tear strength relative to the 3% and 6% groups, maintaining clinical viability.
  • Intrinsic pigments improved color stability compared to controls, helping to prevent UV and sebum discoloration.
