Objective:
This study aims to evaluate oral health education programme and ambulatory dental care service activities of the Mobile Health Units: OdontoSesc-RJ Project, of the Social Service of Commerce in the Regional Department of Rio de Janeiro from 2015 to 2019.

Methods:
An exploratory study was conducted using a historical analysis of the dental procedures, obtained from OdontoSesc-RJ database, in the period 2015-2019. The database included the number of patients seen at the Ambulatory Dental Care (AC) and at the Clinical Session (CS) as well as the total number of appointments provided at AC and CS. The evolution of ambulatory dental care services and health education programmes was evaluated. The data was analyzed in a descriptive manner, using Microsoft Excel 365 software.

Results:
Between 2015 and 2019, a total of 533,603 people were seen and 1,012,126 dental appointments were provided at the OdontoSesc-RJ Project when combining both types of services. An average of five appointments per patient was observed, which maintained constant throughout the four years (2015-2019). The number of appointements at the AC remained constant throughout the four years but a drop was observed at the CS between 2015 and 2016, followed by an increase on the following years, becoming considerate high from 2018 through 2019.

Conclusion:
Between 2015 and 2019, around 500,000 people were seen at the OdontoSesc-RJ Project and more than one million of dental appointments were provided in primary care dentistry. Thus, the importance of this project in providing dental care was observed.
