Observations on the sensitivity of dentine in man
Dentine assumed by many to be richly innervated on account of its high sensitivity
Greater sensitivity of enamel/dentine junction than underlying dentine difficult to explain unless dentine innervated throughout its depth
Latency of response to cold too short for stimulation of nerves in pulp, indicating that dentine was innervated
Lack of effect of topical anaesthetics or of algesic chemicals suggested that nerves were not exposed at a cut dentine surface
