Time series of the production of dental procedures in the Brazilian National Health System, Brazil, 2008-2018

Abstract

Objective: To analyze dental procedures provided by the Brazilian National Health System (SUS) in Brazil and its macro-regions, between 2008 and 2018. Methods: This was a time series study using data from SUS Outpatient Information System. Annual and overall rates of dental procedures (per 100,000 inhabitants), according to the categories of dental procedures and regions were calculated. Prais-Winsten regression was used to analyze time trends, while annual percentage change (APC) was calculated. Results: Decreasing trends were found in Brazil, in collective measures (APC= -13.5%; 95%CI -21.1;-5.2), individual preventive measures (APC= -6.2%; 95%CI -7.7;-4.8), dental restoration (APC= -7.3%; 95%CI -10.5;-3.9) and tooth extraction procedures (APC= -6.9; 95%CI -10,5;-3,1). Endodontics and periodontics showed stationary trend in most regions and Brazil. Prosthetic procedures showed an upward trend in all regions and Brazil (APC= 16.9%; 95%CI 9.1;25.2). Conclusion: Dental procedures in the SUS decreased between 2008-2018; with the exception of prosthetic procedures, which showed a rising trend.
