The document discusses different models of dentist-patient interaction from a psychodynamic perspective. It describes the real relationship as an equal relationship between adults, while the treatment alliance considers the patient's anxieties about treatment merging with the dentist's skills. The transference represents the past and can involve the dentist as a parental figure. Types of interaction are also discussed, including active-passive, guidance-cooperation, and mutual participation. Effective communication between dentist and patient is important to establish understanding and satisfaction with treatment.
