Souza JGS, et al. - Researchers ascertained the use of dental care service during early childhood and the possible socioeconomic inequalities in this use. They used the data from the Brazilian Oral Health Survey (SB Brasil, 2010). As per data, during early childhood, socioeconomic differences in the general use of dental care and in its use for check-ups were identified, suggesting the presence of inequalities. They noted an association of clinical conditions and self-perception with the use.
