    Abstract:
    OBJECTIVE: To prepare a new synthetic macromolecular resin class of denture adhesive (named Comfort-DA). METHODS: Twelve different formulae for denture adhesive were designed by orthogonal design. Each factor affecting tensile bond strength of adhesive was analyzed by ANNOVA to select the best formula. Then the chemical and physical properties, such as tensile bond strength, pH value, and viscosity, were evaluated and compared with Fittydent in vitro also. RESULTS: The effect of content of polyvinyl acetate and cellulose ether on tensile bond strength exhibited no statistical significance (P > 0.05), while ethyl alcohol and CMC-Na showed statistical significance and mutual action (P < 0.05). Results of testing viscosity and shearing stress showed that there was no significant difference between Fittydent and Comfort-DA (P > 0.05), while Fittydent exhibited a significantly lower tensile bond strength than the prepared one (P < 0.05). The prepared adhesive demonstrated a neutral or slightly basic pH. CONCLUSIONS: The generally favorable in vitro performance of the prepared adhesive (Comfort-DA) formulation indicated that it might be efficacious denture adhesive.
