What is the primary cause of porosity found in acrylic dentures?

Show Answers

Extending the curing duration beyond recommended timeInadequate pressure applied during flask processingDeficiency of acrylic resin monomer in the mixAllowing the denture to cool slowly on the bench after curingUsing an incorrect polymer-to-monomer ratio

Explanation

Porosity in acrylic dentures typically arises due to insufficient pressure applied to the flask during processing. Proper pressure ensures the acrylic resin is compacted correctly, preventing air bubbles and voids that cause porosity.
