The kernel of the patient's motivation for oral hygiene should be the conversation which the dentist has with his patient. He should conduct this conversation factually, carefully, without loud or shrill tones. The patient must be told: concerns your own personal interest. The necessary detailed information and technical hints may be left to the assistant or the dental technicians, additional leaflets and even audiovisual aids may supplement the patient's information. The members of the practice must be in agreement on the questions of motivation and information of the patient, so that one does not destroy what another has built up.
