All of the following statements about chemically activated (self-cure) resins are true except which?

Chemically activated (self-cure) resins are materials used widely in dentistry, particularly for restorative procedures. Among the characteristics of these materials, several important factors help determine their usability and longevity.

Long-term storage stability is generally a recognized property of self-cure resins, as they can be stored adequately without significant degradation, provided they are kept away from excessive moisture and temperature fluctuations. Over time, however, these resins may exhibit some yellowing, which is commonly attributed to the nature of the chemicals involved in the curing process and exposure to environmental factors.

When mixed properly, the degree of cure in chemically activated resins is often consistent and reliable, though it can be influenced by variables like temperature and the specific chemical formulation used. However, it's known that the curing process can be sensitive to the mixing technique and timing.

On the other hand, the statement regarding marginal stress buildup being much higher for chemically activated resins than for photocured resins is not accurate. Photocured resins often exhibit better mechanical properties, including lower marginal stress due to the way they cure under light activation, which allows for more controlled and efficient curing within the restoration site. This aspect enhances their performance in terms of stress management compared to their chemically activated counterparts, which
