Microscale model of tooth physiology. (Reprinted from PLoS ONE with permission from PLoS.) (a) A slightly outward displacement of an OP and its CB in response to “outward” flow from the dentinal microtubule into the pulpal space; (b) a slightly inward displacement of an odontoblastic process and its cell body in response to “inward” flow from the pulpal space into the dentinal microtubule; (c) an idealization used to estimate fluid shear stresses on the TB of a nociceptor TF associated with DFF. NF: nerve firing.
