Estudo sobre a fluorose dentária num município do sul do Brasil

Abstract

The objective of this article is to determine the frequency and severity of dental fluorosis, as well as to verify possible associations with dental caries, gender, age, ethnicity and geographic location of schools in schoolchildren of 12 years old and from 15 to 19 years in the city of Passo Fundo, Rio Grande do Sul State, Brazil. A total of 633 schoolchildren of both genders at the cited ages, enrolled in 26 public schools of fundamental teaching were involved in the epidemiological study. The inspection was performed by three examiners previously trained to apply Dean's Index. The prevalence of dental fluorosis in the studied group was of 32.8%. Predominant degree was the very light (78.4%), followed by light (11.1%), questionable (8.7%) and moderate (1.9%). The prevalence of dental fluorosis was expressive in this population, however, with a low degree of severity. Factors such as age and dental caries index showed to be related to the variable response.

Retrospective analysis of the fluoride level in the public water supply and its correlation with dental fluorosis at two cities of South Santa Catarina

“…By using the Dean's index, the "questionable" classification was considered fluorosis, following assertions by Fejerskov et al [16], who consider "questionable fluorosis" because it does not fit into the classification of normal, due to alterations in the dental enamel, characterizing a pathology. In the study of Rigo [30], the "questionable" classification had a prevalence of 8.7%. In our study, no child was classified in the "questionable" classification.…”

“…In the study by Moura et al [24] the TF scale was used, and the prevalence of fluorosis was 61.5%; of these, 70.9% were TF 1, which in comparison with the Dean index is the questionable classification, which some authors consider as nonfluorosis, perhaps explaining the reason for the high prevalence in relation to our study. Rigo [30] published a study in which the prevalence of fluorosis in adolescents between 12 and 19 years of age was 32.8%. By using the Dean's index, the "questionable" classification was considered fluorosis, following assertions by Fejerskov et al [16], who consider "questionable fluorosis" because it does not fit into the classification of normal, due to alterations in the dental enamel, characterizing a pathology.…”

Relation between oral health and socioeconomic variables among schoolchildren aged 12 in the City of Manaus - AM

“…It is noteworthy that in Manaus/AM, in 2004, a low 12.4% prevalence of dental fluorosis was found at age 12 (Moura 2004). The epidemiological surveillance service recommends the monitoring of this disease, since some studies (Salas-Pereira et al 2008;Rigo et al 2010) show a prevalence above 30%, not posing, however, a risk to public health. Furthermore, the proportion of individuals with its moderate and severe forms is still small (Meneghim et al 2006;Carvalho et al 2007).…”

Estudo da prevalência da fluorose dentária em um grupo de escolares de Belém, Estado do Pará, Brasil

“…Outro fator a ser considerado seria o desenvolvimento de ações efetivas de vigilância sanitária para determinar a dosagem ideal de flúor em produtos como suplementos dietéticos, dentifrícios, géis, soluções para aplicação tópica, soluções para bochechos, alimentos e bebidas industrializadas com água fluoretada 11 .…”

“…Os resultados permitem elaborar hipóteses para futuros estudos da associação entre fluorose dentária e CPO-D, conforme observou Dean logo após a descoberta do flúor e seus efeitos sobre o esmalte dentário 7,11,12,13 .…”
