Abstract
|
|
|
The residual monomer leaching into the water from the cured acrylic resins were detected qualitatively by means of 0.003% KMnO4 solution.
The commercially available heat curing acrylic resin, denture repair self-curing acrylic resin and fluid resin were used in this investigation.
The results obtained were as follows:
(1) Heat curing resin
(A) When it was cured under the condition that the flask was heated slowly until 162°-165°F is reached then kept at 162°-165°F for 11/2 hours, and then boiled for 1/z hour, the residual monomer was not detectable.
(B) Under the condition that the resin was allowed to polymerize for only 1 hour at 162°-165°F, the residual monomer was detectable up to 15hours
(2) Self-curing resin.
The residual monomer was detectable up to 18 hours.
(3) Pour resin.
The residual monomer was detectable up to 14 hours.
