This study aimed to understand professors' perceptions towards the use of the reflexive portfolio in the area of public health at the UFPB School of Dentistry. The adoption and evaluation of new methodologies were launched by the Program for the Reorientation of Professional Training in Health (Pró-Saúde). The methodological approach was qualitative, and the data were collected using interviews with professors. The data were processed using the content analysis technique. Two dimensions were identified in use of the portfolio: 1) as a tool for reflection and follow-up of the students' experiences and 2) an analysis of the fact that this two-year experience reveals the need to continue the records, as a way of expanding the teaching/learning process, beyond the dialogue between professors and students, fostering ties between them. Finally, the professors appreciated the need to improve the portfolio's use, which has happened gradually each semester, contributing actively to the development of more reflexive and critical professionals, orienting students' self-evaluation and fostering their autonomy.
