Fluorose dentária em escolares de um município da serra gaúcha, Rio Grande do Sul, Brasil

Abstract

The aim of the present study was to determine the prevalence and severity of dental fluorosis in all schoolchildren (ages 4 to 18 years, n = 259) from the town of Santa Tereza, Rio Grande do Sul, Brazil, and to investigate associated factors. Data were obtained through a questionnaire and by means of clinical tests. Dean's index was used to determine fluorosis occurrence. Prevalence of fluorosis was 63.7%. The predominant category was very mild (43.6%), followed by mild (12.0%), moderate (7.7%), borderline (7.3%), and severe (0.4%). Approximately 85.0% of the schoolchildren currently have, or have had, access to other topical sources of fluoride. Significant associations were found between place of residence and previous or ongoing fluoride mouth rinsing and prevalence and severity of fluorosis (p < 0.05). There was also a significant association between dental fluorosis and parents' level of schooling, frequency of brushing teeth, fluoride rinsing, and use of fluoride gel (p < 0.05).

Agreement between parents and adolescents on dental fluorosis: a population-based study

“…17 However, there has been wide variation in the fluorosis measurement methods that have been used in several studies published in different regions of Brazil and in other countries, as well as differences in the age groups studied and variability among regions; the fluorosis rates ranged from 18% to 80%. 3,5,9,[18][19][20][21][22][23][24][25][26] Thus, it is difficult to compare results because of the diversity of the indices used for dental fluorosis. 27 The clinical diagnosis of fluorosis was not significantly associated with the self-reported assessments of the students who were interviewed about the color of their teeth, and there was no significant agreement between the parents from the cities of Viçosa and Sobral.…”

“…Several studies have confirmed these findings and have shown that fluorosis is not a significant factor in dissatisfaction with tooth appearance and color or with aesthetic appearance changes that are caused by fluorotic spots. [5][6][7][8][9][10]20,22,28 Note that the diagnosis of fluorosis using Dean's Index accounts for the two worse conditions found in the dental arch. As the visualization of fluorosis is easier in the anterior teeth, for the general public, it is suggested that this fact is a complicating factor in the self-assessment of fluorosis.…”

Prevalência e severidade de fluorose em escolares do município de São Francisco do Conde-BA, 2010

“…Prevalências maiores que 30% em municípios com ótimo nível de fluoretação das águas têm sido atribuídas ao uso combinado de fluoretos na água de abastecimento público com outras variadas fontes de fluoreto 4,8 . Considera-se a fluoretação das águas como uma medida efetiva, segura, equânime e barata contra a cárie dentária, 4,9,18,21,27 , este não investigou hábitos alimentares e de higiene oral das crianças, nem a principal fonte de consumo de água nas áreas pesquisadas 20,27 , inviabilizando uma investigação mais aprofundada a respeito da alta prevalência da doença nesta população.…”

“…Os estudos no Brasil mostram uma prevalência baixa e muito variável, desde 3% no município de Catalão-GO 3 , para crianças de sete a 12 anos, até 63,7%, em escolares de quatro a 18 anos do município de Santa Tereza-RS 4 . A prevalência no País é de 8,56%, sendo de , houve a regulamentação do uso de dentifrícios fluoretados; entretanto, as desigualdades socioeconômicas ainda eram uma barreira ao extensivo uso pela população 1,6 .…”
