Overview

Observational study reveals stationary dental implant provision across Brazilian municipalities from 2010 to 2023, highlighting persistent regional healthcare disparities.

Key Points

  • To analyze the temporal trends of publicly funded osseointegrated dental implant procedures in Brazilian municipalities from 2010 to 2023 and examine their associations with municipal socioeconomic indicators.
  • Conducted a time-series observational study using secondary data from the Department of Informatics of the Unified Health System (SUS) in Brazil, following the RECORD statement.
  • Obtained socioeconomic indicators, including Gross Domestic Product (GDP), Municipal Human Development Index (MHDI), and Gini Index, from the Brazilian Institute of Geography and Statistics.
  • Assessed temporal trends using multilevel linear regression and evaluated relationships between implant rates and municipal metrics via Spearman's correlation analysis.
  • Public dental implant provision exhibited an overall stationary temporal trend between 2010 and 2023 (p = 0.69).
  • The Southern region delivered the highest absolute number of implants, followed by the Northeastern region.
  • Implant rates were inversely correlated with municipal GDP (rs = −0.481), MHDI (rs = −0.251), and Gini Index (rs = −0.510).
