Abstract

OBJECTIVES:  To assess the perceptions of and concerns regarding dental fluorosis among 12-15 year-old schoolchildren in an area where fluorosis is endemic and to find any association with Tooth Surface Index of Fluorosis (TSIF) scores. BASIC RESEARCH DESIGN:  A cross sectional study.

PARTICIPANTS:  316 children aged 12-15 years with varying level of dental fluorosis selected from 696 children screened for fluorosis.

METHODS:  The study was undertaken in three villages in rural Gadag, Karnataka, India, with fluoride levels in the drinking water ranging from 2.2 to 4.5 ppm as estimated by the SPADNS spectrophotometric method. Children’s fluorosis was assessed under natural lighting conditions on the labial surface of upper anterior teeth using the TSIF 8-point scale. A self-administered questionnaire assessed knowledge, perceptions and concerns. Data were analysed by frequency distributions and Spearman’s correlation coefficients.

MAIN OUTCOME MEASURES:  Aesthetic perceptions and TSIF scores. RESULTS:  The children were aware of the fluoride presence and its health effects. TSIF scores correlated with: the appearance of front teeth (r = 0.135, p = 0.015); feeling fluorosis would hinder smiling (r = 0.116, p = 0.040); feeling distress due to fluorosis (r = 0.111, p = 0.048).

CONCLUSION:  Children were aware of fluoride and its health effects. They also perceived dental fluorosis as an aesthetic problem.

    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

  • Prevalence of dental fluorosis and treatment needs among 11-14 years old school children in endemic fluoride areas of Haryana, India.

    Introduction: Dental fluorosis is a major endemic oral disease characterized by hypo mineralization of enamel caused due to consumption of water containing high concentration of fluoride during developmental stages of teeth. Aim: To assess the prevalence of dental fluorosis among 11-14 years old school children in endemic

  • Children's perception of other children with dental fluorosis – A cross-sectional study.

    Background: Dental appearance may influence how others perceive individuals. This study would help to understand whether young people make judgments about other young people with dental fluorosis. Aim: We aimed to evaluate the perception of children aged 12–15 years about other children with visible dental fluorosis. Materials and methods: A self-administered social

  • 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.

    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

    When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

  • 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
