Abstract

This reaction time study assessed the valence and strength of evaluations of people with differing levels of fluorosed teeth. Eighty participants rated photographs of smiling faces with four levels of digitally manipulated fluorosed teeth. Faces were presented on a computer screen for a period of 2000 ms followed by a single word descriptor. Participants quickly indicated whether the descriptor applied to the preceding face using a response key. Descriptors included health, aesthetic, and personal judgments. Logistic and linear regressions revealed that participants were significantly more likely to make negative judgments involving health, aesthetic, and person attributions about faces with high levels of fluorosis, and to make negative judgments more quickly and positive judgments more slowly than those with lower levels of fluorosis. These data are consistent with the view that people use negative, easily accessible, stereotypes of individuals presenting with health problems.

  • Development of a questionnaire to measure perceptions of, and concerns derived from, dental fluorosis

    OBJECTIVE: To develop a questionnaire in English and Spanish to measure concerns caused by children's (and their parents') perceptions of dental appearance. MATERIALS AND METHODS: The questionnaire addressed concerns in the physical, mental, and social domains, perceptions about discolourations and other oral conditions including tooth colour. Test-retest and internal reliability,

  • Aesthetic concerns of children and parents in relation to different classifications of the Tooth Surface Index of Fluorosis

    Increasing prevalence of dental fluorosis for children both from fluoridated and non-fluoridated communities are now well documented. Along with recent studies purporting possible adverse health effects from fluorides, this proven public health intervention is again being challenged. This study was undertaken to determine the prevalence of dental fluorosis for children

  • Perceptions of adolescents and young people regarding endemic dental fluorosis in a rural area of Brazil: psychosocial suffering

    Severe dental fluorosis is endemic in some rural areas of Brazil. This paper describes the psychosocial consequences of this condition and how it has affected the self-esteem of adolescents and young people in a rural area in Brazil. Semi-structured, face-to-face interviews were carried out with 23 adolescents and young people

  • Factors associated with parents' esthetic perceptions of children's mixed dentition fluorosis and demarcated opacities

    PURPOSE: With the increasing prevalence of dental fluorosis, improved understanding about esthetic perceptions of dental fluorosis is warranted. The purpose of this report was to present results concerning parents' overall satisfaction with the appearance of their children's teeth and factors related to dissatisfaction, comparing subjects with and without fluorosis and

  • Parents' satisfaction with children's tooth color: fluorosis as a contributing factor

    The authors surveyed parents of 708 patients in a pediatric dental practice about their satisfaction with the color of their children's teeth and factors associated with their level of satisfaction. Overall, 43 percent of parents were dissatisfied with their children's tooth color, and 78 percent of children had a Tooth

  • Dental Fluorosis Is a "Hypo-mineralization" of Enamel

    Teeth with fluorosis have an increase in porosity in the subsurface enamel ("hypomineralization"). The increased porosity of enamel found in fluorosis is a result of a fluoride-induced impairment in the clearance of proteins (amelogenins) from the developing teeth. Despite over 50 years of research, the exact mechanism by which fluoride impairs amelogin

  • Community Fluorosis Index (CFI)

    The current Community Fluorosis Index for U.S. adolescents as a whole (from both fluoridated and non-fluoridated areas) is roughly 5 times higher than the CFI health authorities predicted for fluoridated areas when fluoridation first began. It is also higher than the CFI that the NIDR found in fluoridated areas back in the 1980s. It is readily apparent, therefore, that children are ingesting far more fluoride than was the case in the 1950s, and even as recently as the 1980s.

  • Racial Disparities in Dental Fluorosis

    In 2005, the Centers for Disease Control published the results of a national survey of dental fluorosis conducted between 1999 and 2002. According to the CDC, black children in the United States have significantly higher rates of dental fluorosis than either white or Hispanic children. This was not the first time that black children were found to suffer higher rates of dental fluorosis. At least five other studies -- dating as far back as the 1960s -- have found black children in the United States are disproportionately impacted by dental fluorosis.

  • Moderate/Severe Dental Fluorosis

    In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel. After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth. In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.
