2. The following inflammatory mediator(s) is/are not elevated in the pulp, in cases with

vExplain:
● Symptomatic irreversible pulpitis is a condition where the pulp tissue in the
v v v v v v v v v v v




v tooth is inflamed and cannot heal, resulting in persistent pain and sensitivity.
v v v v v v v v v v v




v Several inflammatory mediators are involved in this process, including
v v v v v v v v




v prostaglandins (option a), bradykinin (option c), neuropeptides (option d), and
v v v v v v v v v




v matrix metalloproteinases (option e). These mediators can cause pain,
v v v v v v v v




v swelling, and tissue damage. v v v




● Leukotrienes are lipid mediators involved in the inflammatory response, but
v v v v v v v v v




v they are not typically elevated in cases of symptomatic irreversible pulpitis.
v v v v v v v v v v




v Instead, they are more commonly associated with other inflammatory
v v v v v v v v




v conditions, such as asthma and allergies.
