A review of the literature on dental treatment was conducted and models presented of the doctor/dentist-patient relationship. These models are listed and divided into two subgroups, empirical and normative models. The models are scrutinized with focus on the dentist-patient communicative relationship exclusively. Different doctor/dentist-patient relationships are described. External factors influencing these relationships are defined. An analysis of dentist-patient communication is made, and a new model of dentist-patient communication is suggested, which states that what is done and what is said during dentist-patient encounters will have an impact on outcome. Three different purposes of dentist-patient communication are presented. The process of attaining these is discussed. It is concluded that a theory of communication is lacking in the dental context, and the need to develop a reliable and valid interaction analysis system for the patient-dentist communication is confirmed.
