Finally, the dentist selects the appropriate treatment option by answering the questions "What should be done?" and "Why should it be done?" Although it is inherent in the process, perhaps a fourth step should be added: to arrive at a treatment option that is acceptable to both the patient and the dentist. Autonomy, or the patient's decision about treatment, is an important This article presents four case reports that illustrate how ethical Fig. 1.
