[The interface between primary and secondary care in dentistry in the Unified Health System (SUS): an integrative...

Secondary care in dentistry in Brazil has scarce and broadly underutilized resources. The challenge is to organize the interface between primary health care (PHC) and secondary care in order to consolidate the population's access to specialist dental care in the Unified Health System (SUS). This article seeks to analyze national publications in Portuguese and English on the interface between secondary health care and primary health care in dentistry from the perspective of comprehensive care in the SUS. It is an integrative review, considering the publications of the following databases: SciELO (Scientific Electronic Library Online), LILACS (Latin American and Caribbean Literature) WEB OF SCIENCE, SCOPUS, PubMed (International Literature on Health Sciences) and GOOGLE SCHOLAR. The search located 966 articles, of which 12 were used in full. Coverage of the oral health teams (ESB) in the family health strategy (ESF), primary health care implementation in a structured way, access to secondary health care, counter-referral to PHC, development of indicators and socioeconomic conditions and inequalities in the distribution of dental specialist centers (CEO) are factors that influence the integrity of oral health care in the SUS.
