Colorism is a persistent problem for people of color in the USA. Colorism, or skin color stratification, is a process that privileges light‐skinned people of color over dark in areas such as income, education, housing, and the marriage market. This essay describes the experiences of African Americans, Latinos, and Asian Americans with regard to skin color. Research demonstrates that light‐skinned people have clear advantages in these areas, even when controlling for other background variables. However, dark‐skinned people of color are typically regarded as more ethnically authentic or legitimate than light‐skinned people. Colorism is directly related to the larger system of racism in the USA and around the world. The color complex is also exported around the globe, in part through US media images, and helps to sustain the multibillion‐dollar skin bleaching and cosmetic surgery industries.

Circumstantial evidence based on anecdote, case reports, epidemiological data and studies in vitro and in situ implicate tooth brushing with toothpaste with tooth wear, gingival recession and dentine hypersensitivity. This review attempts to assess the clinical significance of the potential harm produced by this most common oral hygiene habit. The toothbrush alone appears to have no effect on enamel and very little on dentine. Most toothpaste also has very little effect on enamel and in normal use would not cause significant wear of dentine in a lifetime of use. Wear of enamel and dentine can be dramatically increased if tooth brushing follows an erosive challenge. Gingival recession has a multi-factorial aetiology and certain individuals and specific teeth may be predisposed to trauma from tooth brushing. Tooth brushing is known to cause gingival abrasions but how these relate to gingival recession is not known. The role of toothpaste in gingival abrasion and recession surprisingly has received little if any attention. Gingival recession most commonly exposes dentine and localises sites for dentine hypersensitivity. Some toothpaste products can expose dentinal tubules but erosion is probably the more dominant factor in dentine hypersensitivity. There is no evidence to indicate that electric and manual toothbrushes differ in effects on soft and hard tissues. It is only under, over or abusive use or when combined with erosion that significant harm may be thus caused. In normal use it must be concluded that the benefits of tooth brushing far out-way the potential harm.

The majority of respondents possessed, at best, rudimentary knowledge of the emergency management of dental avulsion. Teachers, and other individuals who supervise children in schools, should receive simple instruction in dental first aid.

It is concluded that statistically significant differences in susceptibility of deciduous and permanent enamel to erosion appear to emerge over time and with increasing frequency of consumption. This is of importance clinically given the reduced dimensions of the deciduous dentition and the element of 'abuse' of soft drinks by the child population. Further development of soft drinks with low erosive potential is recommended.

This paper examines the stratification among African American women by skin color on indices such as education, income, and spousal status. How racial and colonial ideologies situate whiteness and blackness as symbolic representations in relation to one another and the subsequent systems of discrimination that develop from those ideologies is the crux of the theoretical argument in this paper. Infusing the concept of constructed notions of beauty into this racial paradigm further elaborates this process for African American women. I hypothesized that light-skinned women would have higher educational attainment, higher personal incomes, and would be more likely to many highstatus husbands than would darker-skinned women. Even when controlling for background variables, all three of the hypotheses are confirmed and the significance of skin color, particularly the privileging of lightness, is demonstrated.
