ABSTRACT

PURPOSE: To compare the prevalence and severity of fluorosis in the permanent maxillary incisors of children who had participated in a two-year randomized placebo-controlled clinical trial on fluoride varnish application in the primary dentition and to assess children's esthetic perception of their teeth. METHODS: Parents of 200 one- to four-year-old children who had received biannual applications of fluoride or placebo varnish were contacted four years after the end of the trial. Two calibrated examiners assessed dental fluorosis using the Thylstrup and Fejerskov index (TF) and interviewed the children regarding their perceptions of teeth appearance. RESULTS: Fluorosis (TF equals at least one) and esthetically objectionable fluorosis (TF equals at least three) were observed in 38 (30.9 percent) and eight (6.5 percent) children, respectively. There was no statistically significant difference in fluorosis prevalence between children who had received fluoride or placebo varnish. Children's responses regarding the esthetic perceptions of their teeth showed no statistically significant difference between children with and without fluorosis. CONCLUSIONS: Fluoride varnish applications in preschoolers were not associated with any level of fluorosis in their permanent maxillary incisors. The fluorosis found in this study did not influence the children's esthetic perception of their teeth.

ABSTRACT

O objetivo deste ensaio clínico foi avaliar o efeito adicional do verniz fluoretado sobre a inativação de lesões iniciais de cárie em dentes decíduos submetidos a 6 sessões de escovação profissional com dentifrício fluoretado. Critério de inclusão: mancha branca ativa (MBA) na face vestibular de incisivo/canino decíduo superior. Participaram 12 crianças(9 a 48 meses de idade), totalizando 29 MBA. As crianças foram alocadas aleatoriamente em 2 grupos: sem vernizfluoretado (SF) e com verniz fluoretado (CF). Ambos receberam 6 sessões de escovação dentária profissional com dentifrício fluoretado com intervalo médio de 1,2 semanas. O grupo CF recebeu aplicação de verniz fluoretado após cada escovação. Um único examinador cego, calibrado para cárie dentária (k=0,71) e biofilme dental (BF) (k=0,71) e treinadopara sangramento gengival (SG), avaliou os dentes em: baseline, intermediário e final. Os dados foram analisados no SPSS, utilizando os testes χ2 e exato de Fisher. Ao final, 22 (75,7%) lesões foram consideradas inativas e não houve diferença entre os grupos (p=0,295). A combinação dos dados de BF e SG originou o padrão de higiene da superfície dentária (PHD) que esteve associado à inativação das lesões (p=0,010). Clinicamente, não se observou efeito adicional do verniz fluoretado na inativação das lesões de cárie. Esta esteve associada à melhora do PHD, uma vez que a maiorproporção de inativação ocorreu dentre as superfícies que apresentaram melhor qualidade de higiene.
