A patient reports sharp, brief pain to cold drinks that resolves immediately upon removal of the stimulus. Which mechanism best explains why cold is a more potent trigger of dentinal hypersensitivity than an equivalent heat stimulus?
Select the correct answer
A.
Cold causes vasoconstriction of pulpal vessels, reducing intrapulpal pressure and amplifying the pressure differential across exposed dentinal tubules
1
B.
Cold stimuli directly depolarise A-delta nerve fibres at a lower threshold than heat, as cold-sensitive ion channels have greater expression in the pulp
2
C.
Cold lowers the viscosity of dentinal tubule fluid, increasing overall flow rate irrespective of direction and thus providing greater mechanoreceptor stimulation
3
D.
Cold produces outward fluid movement within dentinal tubules, which is the directional flow most effective at activating A-delta mechanoreceptors at the pulp-dentine interface
4
E.
Cold causes contraction of odontoblast processes, generating a pressure wave that propagates centrally and depolarises adjacent nerve fibres more readily than heat-induced expansion
