A presença de fluorose dentária estaria associada ao traumatismo dentário entre escolares? / Is there an association between the presence of dental fluorosis and dental trauma amongst school children?

RESUMO

Resumo Objetivou-se avaliar se diferentes graus de fluorose dentária estão associados à presença de traumatismo dentário entre escolares. Trata-se de um estudo transversal conduzido entre escolares de 12 anos. Os exames foram realizados por 24 cirurgiões-dentistas treinados e calibrados. A coleta de dados ocorreu em 36 escolas públicas sorteadas entre as 89 do município. Adotou-se como critério de diagnóstico para fluorose dentária o Índice de Dean e para o traumatismo dentário considerou-se sinais clínicos de fraturas coronárias e avulsão dentária. Foram conduzidas análises descritivas, bivariadas e múltiplas. Entre os 2755 escolares incluídos, 1089 (39,6%) foram diagnosticados com fluorose dentária e 106 (3,8%) possuíam um dente ou mais com traumatismo. Identificou-se maior prevalência da fluorose dentária, independente do grau de severidade, entre indivíduos com um dente ou mais com traumatismo dentário. Essa associação foi mais forte com os graus mais severos de fluorose. Além disso, constatou-se que a presença de fluorose foi maior entre aqueles com autopercepção da presença de manchas nos dentes e que recebiam assistência odontológica na escola. Portanto, a fluorose dentária foi associada à presença de traumatismo dentário, independente de sua severidade.

ABSTRACT

Abstract Our objective was to evaluate whether there is an association with the different levels of dental fluorosis and the presence of dental trauma amongst school children. A transversal study was conducted amongst school children from the age of 12. Dental examinations were conducted by 24 well trained and fully qualified dental surgeons. Data was collected from 36 randomly selected public schools amongst 89 schools in a municipality. The criteria used to diagnose dental fluorosis was based on the Dean’s fluorosis Index and for diagnosing dental trauma we looked for clinical signs of crown fractures and dental avulsions. Multiple descriptive analysis, which was bivariate, was carried out. Amongst the 2,755 school children that took part in the study 1,089 (39.6%) were diagnosed with dental fluorosis and 106 (3.8%) had one tooth or more with dental trauma. We noted a high prevalence of dental fluorosis, independent of the level of severity, amongst individuals with one tooth or more who had dental trauma. This association was even more evident where there were severely high levels of fluorosis. We also noted that the presence of fluorosis was greater amongst those that actively paid more attention to discoloration on their teeth and who received treatment from a dental professional at their schools. Nevertheless dental fluorosis was associated with the presence of dental trauma, independent of its severity.
