Supply of Inputs and Procedures Non-Invasive and Micro-Invasive in Primary Care: Historical Series by Brazilian Regions.

Objective: To analyze the supply of input and procedures, non-invasive and micro-invasive, for dental caries lesions in Primary Care in Brazil, comparing the Brazilian geographic regions in three different periods. Material and Methods: Historical series study based on secondary data extracted from the 1^st Cycle (2012), 2nd (2014), and 3^rd cycle (2018) of the External Evaluation of the National Program for Access and Quality of Primary Care. The proportions of Oral Health Teams offering non-invasive (fluor) and micro-invasive (sealants) supplies and procedures between Brazilian geographic regions were compared using the Chi-square test, using the Z Test adjusted by the Bonferroni method, and between the years (2012, 2014, and 2018) using the Cochran Q test (p<0.05). The percentage variation between the proportions per cycle was calculated. Results: The availability of inputs of fluor gel in Brazil increased between 2014 (91.6%) and 2018 (94.1%) (p<0.001), but statistically only in the Northeast and North (p<0.001). The offer of the topical fluorine procedure increased between 2012 (78.8%) and 2018 (87.4%) (p<0.001) in Brazil, with the most significant increase in the North (+7.5%) and Northeast (+22.0%). There was greater availability of inputs of sealants in Brazil between 2012 (56.8%) and 2018 (69.5%) (p<0.001) in Brazil, and more significant expansion in the Northeast (+43.4%). There was a greater offer of the sealing procedure in Brazil between 2014 (98.6%) and 2018 (98.5%), compared to 2012 (94.7%) (p<0.001), with more significant expansion in the North (+5.8%). Conclusion: There was an increase in the supply of input and procedures, non-invasive and micro-invasive, in Primary Care in Brazil. Despite maintaining regional inequalities, they were reduced, with greater expansion in the North and Northeast regions between the years evaluated. [ABSTRACT FROM AUTHOR]
