A new skin protecting ointment against acrylic resins.

In order to protect the hands of dentists, dental technicians and dental nurses from direct contacts with acrylic monomer, a new type of protective monoglyceride containing ointment has been introduced. The monoglyceride-based ointment was found to prevent penetration of the monomeric part of an autopolymerising acrylic resin and was also shown to have significantly smaller decreasing influence on the ability to manipulate instruments and materials than a compared silicone-based ointment. Furthermore, even with addition of 1% by volume of the monoglyceride-based ointment there was no marked influence on the mechanical properties (elastic modulous and ultimate tensile strength) of an investigated acrylic tray material.
