The most unfavorable prognosis is associated with which reaction?

• A. Accompanies partial reaction of degeneration
• B. Accompanies full reaction of degeneration
• C. Accompanies absolute reaction of degeneration
• D. Reaction of degeneration is not involved

Answer: (C)

The extent of a degenerative reaction directly influences prognosis: the more completely degeneration involves the tissue, the poorer the outcome. When degeneration is only partial, some healthy tissue remains and function can be preserved or restored, giving a relatively better prognosis. A full reaction means widespread degeneration, leading to substantial functional loss, but there may still be some residual capability. However, an absolute reaction indicates that all components are degenerated, leaving little to no viable tissue to recover and making recovery unlikely. If degeneration isn’t involved at all, the prognosis would naturally be the most favorable. Therefore, the absolute reaction of degeneration corresponds to the most unfavorable prognosis.
