Effects of temperature-responsive hydrogel on viscosity of denture adhesives.

Abstract:

:The cream type of denture adhesives after use cannot be easily removed from oral mucosa and have the potential risk to change the oral flora. The effects of the temperature-responsive hydrogel Pluronic F-127 (PF) on the complex viscosity of denture adhesives were evaluated. Carboxy methylcellulose (CMC) mass fractions (1, 2, 3 and 4%) were added to 20 and 25% PF hydrogels. Complex viscosity was measured over a temperature cycle (40→10→40°C) and fixed temperature points (23 and 37°C). Adhesive strength tests were performed with 2 resin plates at 23 and 37°C. One commercial cream-type denture adhesive, New Poligrip® (NP), was evaluated as a control. Complex viscosity values for PF20% groups at 23°C were lower than those for NP at 37°C. Adhesive strength of PF20% with CMC2%, was higher at 23°C when compared to NP at 37°C, which suggests that PF20%CMC2% is an effective adhesive and is easily removed after mouth rinsing.
