Abstract

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, and construct and criterion validity, were assessed as part of the development process. Children in Mexico City, Mexico and Indianapolis, Indiana answered the questionnaire and were examined for fluorosis using the TSIF index. Data were analysed using Cronbach’s alpha, Pearson’s, Spearman’s and intraclass correlations, and percentage agreement tests. RESULTS: Ninety-five children and 28 parents participated in Mexico City; fluorosis was diagnosed in 66% of children. Seventy-one children and 65 parents participated in Indianapolis; fluorosis was diagnosed in 63% of children. English and Spanish questionnaires had acceptable test-retest performance, and moderate internal reliability. Criterion validity was acceptable, and the translated versions retained acceptable construct validity. Perceptions of discolourations were associated with concerns of the participants. Level of concern was higher in Indianapolis than in Mexico City, generally. Many participants reported that they were at least occasionally distressed or worried over the appearance of the children’s teeth, that it hindered children from smiling freely, and that it was an unsatisfactory appearance. CONCLUSION: The developed questionnaire allowed children and parents to report perceived dental appearance problems and concerns.

  • 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

  • A reaction-time study of social, health, and personal attributions in relation to fluorosed teeth.

    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

    OBJECTIVE: This study aimed to assess the perceived oral health status and to explore its relationship with clinically assessed dental fluorosis among school children in Arusha town, Tanzania. METHODS: A total of 478 students (mean age 15.7 years) completed questionnaires administered in the schools during May to July 2000. Clinical

  • An assessment of teenagers' perceptions of dental fluorosis using digital simulation and web-based testing

    OBJECTIVES: To develop a new model to establish teenagers' perceptions of the aesthetic impact of fluorosis, in the context of overall facial appearance. This web-based model was used to compare different degrees of fluorosis at any one distance, while also comparing the same level of fluorosis at different 'distances'. METHODS:

  • A pilot study of esthetic perceptions of dental fluorosis vs. selected other dental conditions

    The prevalence of fluorosis has increased over the past fifty years, and with this increase, esthetic concerns pertaining to fluorosis should also be taken into consideration. Canadian, Australian, and British studies have explored perceptions concerning enamel fluorosis, but no studies in this area have been published from the United States.

  • 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.

    The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean.

  • Dental Fluorosis Impacts Dentin in Addition to Enamel

    Dental fluorosis is a mineralization defect of tooth enamel marked by increased subsurface porosity. The enamel, however, is not the only component of teeth that is effected. As several studies have demonstrated, dental fluorosis can also impair the mineralization of dentin as well. As noted in one review: "The fact that

  • 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.
