A 45-year-old patient

comes to the dental emergency at night for an acute toothache. Previously, the

given tooth was more sensitive to cold or warm stimuli. Now the pain is

throbbing and constant, and cold stimuli tend to relieve it. Common analgesics

are ineffective. The patient is diagnosed with acute pulpitis, inflammation of

the dental pulp. The dental pulp is mainly made up of loose connective tissue,

which is also the reason why inflammation spreads easily here. What important

type of cell is also part of the pulp chamber?
