Frequent transportation is supposed to buffer issues with distance, while infrequent services impede the uptake of care. The role of public transportation on the accessibility of health care\u2014including oral health care\u2014is not well elucidated in the context of megacities, such as the municipality of S\u00e3o Paulo, Brazil. This study aimed to compare the supply of public transportation to primary dental clinics and the population between advantaged and disadvantaged areas in S\u00e3o Paulo city.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 4101 primary dental clinics in S\u00e3o Paulo city were identified and geocoded. Geographic coordinates were also retrieved for the 19\u00a0242 bus stops, 56 commuter rail stations and 64 rapid transit stations. Clinic locations and transport points were integrated with the city's 19\u00a0128 constituent census tracts\u2014each containing sociodemographic data on the 11\u00a0252\u00a0204 residents\u2014using Geographic Information Systems (GIS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Almost all clinics were located within 0.5\u00a0km of public transportation. Half of all clinics were within 0.5\u00a0km of high\u2010frequency transport points, and three\u2010quarters were within 1\u00a0km. Likewise, 99% of the population resided within 0.5\u00a0km of any public transportation. However, only 22% were within 0.5\u00a0km of high\u2010frequency options, and half were within 1\u00a0km. Those within 0.5\u00a0km of high\u2010frequency points had higher average monthly household incomes and lower illiteracy rates, with lower proportions of children and ethnic minorities, and higher proportions of older people.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Clinics and populations in sociodemographically disadvantaged tracts have poorer public
