Point out the limitations and potentialities of using secondary data in the studies.


• Borges et al_2009_Mortalidade por câncer de boca: due to the use of pre-existing aggregated data, it was not possible to obtain the necessary individual detail for a more accurate investigation, in addition to the sub-registers verified in less developed capitals. On the other hand, because the study was conducted by region in the same city, socioeconomic differences were detected between central and peripheral neighborhoods. Thus, the use of this data, with the delimitation of micro-areas, allowed for greater specificity of the results and the association between cancer mortality and social indicators could be verified.
• Bueno et al_2014_Determinantes sociais e saúde bucal de adultos nas capitais do Brasil: a limitation found in the study is that the information obtained from a population cannot be inferred for the individual. In addition, the chances of cross-classification and migration between individuals from different strata of the population need to be weighed in the interpretation of the results. On the other hand, the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population.
• Freire et al_2012_Dor dentária e fatores associados em adolescentes brasileiros: the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population. However, the study is limited by the fact that it is based on self-reported data, which may be subject to bias.
• Herkrath et al_2013_Desempenho dos CEOs frente ao quadro sociodemográficos dos municípios do Amazonas: the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population. However, the study is limited by the fact that it is based on data from the SIA-SUS, which may be subject to underreporting and incomplete information.
• Herkrath, Vettore, Werneck_2018_Contextual and individual factors associated with dental services utilisation by Brazilian adults: the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population. However, the study is limited by the fact that it is based on self-reported data, which may be subject to bias.
• Leite et al_2018_EQUITY IN SPATIAL DISTRIBUTION OF PRIMARY HEALTH CARE IN THE CITY OF MANAUS, AMAZONAS, BRAZIL: the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population. However, the study is limited by the fact that it is based on data from the CNES/Datasus, which may be subject to underreporting and incomplete information.
• Luquetti, Koifman_2010_Qualidade da notificação de anomalias congênitas pelo Sistema de Informações sobre Nascidos Vivo_estudo comparativo nos anos 2004 e 2007: the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population. However, the study is limited by the fact that it is based on data from the SINASC and ECLAMC, which may be subject to underreporting and incomplete information.
• Santos et al_2015_Utilização dos serviços de atendimento odontológico hospitalar sob sedação e/ou anestesia geral por pessoas com necessidades especiais no SUS-MG, Brasil: the use of secondary data allowed for the analysis of a large sample, which is representative of the Brazilian population. However, the study is limited by the fact that it is based on data from the SIH/SUS and SCNES, which may be subject to underreporting and incomplete information.
