Porosity occuring in the bulky portions of the heat-cured acrylic complete dentures is due to
1) Insufficient pressure application during packing
2) Time lag between packing and curing
3) Directly placing the packed resin in water at 100 degree
4) Using a fluid pour technique
Prosthodontics
Answer: 3
Porosity in heat-cured acrylic dentures can occur due to several factors, but the most significant cause in this context is the direct placement of the packed resin in water at high temperatures (100 degrees Celsius). When the packed resin is subjected to such conditions, it can lead to rapid polymerization and the formation of bubbles or voids within the material, resulting in porosity. This is because the heat causes the monomer to vaporize, and if the vapor cannot escape, it leads to trapped air pockets.
