Method and device for preparing the hard structures of teeth for the application of dental restorative materials

A device for preparing the hard structures of teeth for the application of dental restorative materials over an adhesive substance of a dental bonding system, comprising:

• at least one handpiece connected to a control power circuit for applying an electrical field to at least one layer of the adhesive substance of the dental bonding system applied at least to an affected zone of the hard structure of the tooth previously treated to remove the layer of tissue affected by the disorder, the control power circuit constructed and arranged for operative connection to the hard structure of the tooth;
• and
• an electrode connected to the control power circuit and designed to be placed at any given point on the patient's body and operating in conjunction with the handpiece to apply a difference in potential between the zone treated and covered with the layer of adhesive substance and the given point of application of the electrode, thus generating, at least at the zone treated, an electrokinetic force due to the passage of electrical current able to move the adhesive substance in an even, deep way within the dentinal micro-tubules, so that it covers the irregular surface of the enamel of the tooth.
