This research aims to map the processes existing in a dental clinic. For such, field research procedures were adopted, which were performed at a union dental clinic located in São Paulo-SP city. The data collect was made through non-participant observation and focused (semi-structured) interview. The processes of the clinic were modeled with the aid of MS-Visio Professional 2013 software, in order to clarify the usefulness and participation of each component of the process. The flowcharts built in the research were validated with the technical coordinator of the clinic, who corrected their inconsistencies with the reality in the clinic. After that, the flowcharts were validated with an expert in management. The results make possible to understand the usefulness of each process and identify both the hierarchy of the processes and the key processes; and provide a basis for decision-making. Considering the business model of the clinic, the analysis of the results pointed out an opportunity of increasing the number of patients seen at the clinic. Process mapping provides a better understanding of the routines of the clinic as well as of their steps, and it may help managers to determine their processes and focus on them. So, it understands here that process management is applicable in dental clinics starting from process mapping.
