Camouflaged prejudice and the affirmation of skin colour differences: assessment of racism among Brazilian undergraduate dental students.

The negative oral health outcomes of disadvantaged racial groups have been well-documented, as racial disparity in oral health persists over time and in different locations1. However, it is important to note that skin colour has no biological meaning, and the observed differences can be physiological expressions of social injustice such as racism. Aim: The aim of this study was to analyse the association between levels of modern racism (camouflaged prejudice and affirmation of differences) and sociodemographic characteristics of Brazilian dental students. Material and Method: An epidemiological cross-sectional online survey was conducted on 441 Brazilian undergraduate dental students using Google Forms. Participants were recruited via emails and social media, using the snowball technique. The Checklist for Reporting of Survey Studies (CROSS) was followed. The survey used sociodemographic variables, and the Brazilian version of the Modern Racism Scale (B-MRS), which measures the cognitive component of subtle racial attitudes. The scale assesses the central notion of disguised prejudice and has two domains: 'denial of prejudice' and 'affirmation of differences'. Participants' self-declared skin colour was categorized as "white" and "non-white" (black, brown, indigenous, yellow). Univariate analysis and Poisson regression with robust variance were applied. Results: Participants' mean age was 24.1 years (±5.4). Most participants were self-declared as white (54%) and 46% as non-white skin colour. Higher B-MRS overall-scores were observed in male (p=0.008) and non-white (p=0.002) students. B-MRS scores for the domain 'affirmation of differences' (representation of those who believe that whites and non-whites are truly different) were higher among male dental students (PR=1.138; CI 95%: 1.019-1.271) and those from low-income families (PR=1.306; CI 95%: 1.089-1.565). Scores for the domain 'denial of prejudice' (the idea that non-whites use their race to receive legal benefits) were higher among male dental students (PR=1.328; CI 95%: 1.129-1.562). Conclusions: In general, male non-white students had higher modern racism indicators. Male students from low-income families believed that whites and non-whites are truly different, accounting for the affirmation of difference in this sample.
