Aim: Dentine hypersensitivity (DH) is characterized by a short, sharp pain arising from exposed dentin. Most published literature reports on peripheral neural aspects of this pain condition. The current investigation focused on differential cerebral activity elicited by stimulation of sensitive and insensitive teeth by means of natural air stimuli. Materials and Methods: Five graded stimulus strengths were randomly applied by means of a multi-injector air jet delivery system, each...
