From these, categories emerged that identify processes, attitudes and behaviors that define the assessment of care providers based on their practices. results: In an interactional context characterized by the patient’s expectation regarding the provision of care and anxiety due to potential pain, two already recognized main axes emerged, namely: the capacity to generate trust through interpersonal and communicative good treatment strategies, and the capacity or technical skills of the professional care provider. conclusion: This study proposes a protocol of good care practices, which takes into account the needs and expectations of patients regarding the role of the dentist.
