Objective: To describe the primary care actions performed by oral health teams (OHTs) that participated in a large national survey led by the Ministry of Health in 2012. Methods: A total of 12,403 dentists from OHTs completed a set of survey questions (response rate = 85.01%) on the organization of care, basic dental procedures and oral health surveillance actions of OHTs. Descriptive and hierarchical cluster analyses were developed. Results: The majority of OHTs (85.2%) reported that they performed “patient welcoming”. The delivery of services was based on a patient’s identified disease risk (83.1%), and continuity of care was ensured by 85.9% of OHTs. Individual preventive, restorative and surgical procedures were performed by the majority of the teams; however, screening for oral cancer and construction of dental prostheses/dentures occurred less frequently. Cluster 1 was composed of OHTs with the lowest proportion of oral healthcare actions related to oral cancer and dental prostheses/dentures, and the Southeastern and Southern regions had higher proportions of OHTs from cluster 2. Conclusions: OHTs adhere to some of the principles of primary care organizations; however, the teams perform fewer actions related to oral cancer treatment and rehabilitation with complete dentures. The geographical distribution of the clusters was unequal in Brazil.
