Skin color affect the replacement of amalgam for composite in posterior restorations: a birth-cohort study

Abstract

The aim of present study was to estimate the occurrence and associated factors for replacement of amalgam posterior restorations. A representative sample of all 5,914 births from the 1982 in Pelotas birth cohort study was prospectively investigated, and the posterior restorations were assessed at 24 (n = 720) and 31 years of age (n = 539). Individual-level variables, i.e., demographic characteristics, socioeconomic factors, oral health conditions and use of dental services, were collected from different waves of the cohort. Toothlevel variables included dental group, estimated time in mouth of each amalgam restoration, and number of restored dental surfaces. Thus, 246 individuals presented 718 amalgam restorations at 24 years of age. After 7 seven years of follow-up, 18.9% of these restorations had been replaced with composite resins. Multilevel Poisson regression models showed that, compared to white individuals, blacks presented a lower risk of replacement of amalgam restorations for composite resins (IRR-0.39 [0.16-0.95]). Individuals with high educational level at age 31 showed an increased likelihood of replacement of amalgam restorations. Therefore, skin color affects the replacement of amalgam for composite resin in posterior restorations.

Racial and regional inequalities of dental pain in adolescents: Brazilian National Survey of School Health (PeNSE), 2009 to 2015

“…Thus, unequal relationships between social groups shape their distribution to adverse exposures and health conditions. Discrimination in oral health services in Brazil has been highlighted in a recent study 32 and racism has also affected the dentists' decision concerning the replacement of amalgam restorations 33,34 , emphasizing the structural racism that stereotypes and stigmatizes these populations 10 . In this way, it is important to deeply discuss the social-historical roots of Brazilian racism.…”

Moreover, dentist's treatment decision-making is not only influenced by the patients' oral condition, being influenced by cost of treatments and patients characteristics, such as skin color and economic status 40,41,42,43 .…”

Dentist’s preferences on vital and nonvital tooth bleaching

“…Besides, the complete understanding of mechanisms that professional decision making is a hard task and can englobe several levels of comprehension, beginning in the professional knowledge 17,24 , influenced by the school of dentistry and, also, can be influenced by patients' characteristics [25][26][27] . Some patient's characteristics could influence the decision making of health professionals [25][26][27] . Moreover, it was observed that competition affected the clinical decision-making of dentists in Canada 28 .…”
