Abstract

Objective: The aim of this research was to evaluated the cariostatic effect of four different types of sealants. Material and method: 48 bovine incisors were used in this study. It were submitted to pH cycling. A groove of approximately 1 mm of depth and 2 mm of wide were made on the samples to simulated a central sulcus. The samples were randomly divided into 4 groups with 12 samples each: Grupo 1) Alpha Seal Auto; Grupo 2) Alpha Seal Ligth; Grupo 3) Conseal F; Grupo 4) Ketac Fill Plus. They were subsequently submitted to thermal and pH cycling. Three slices were obtained from each tooth, for analysis using a polarized light microscopy. It were measured the depth of external lesion and of width of the wall lesion. The numeric values ​​were statistically analyzed using the Kruskal Wallis and Mann-Whitney test, at the level of 5% of significance. Result: It was observed significant difference between the 4 groups regarding the depth of outer lesions (p < 0.05), and width of the wall lesions (p < 0.01). The material which presented the lowest depth of external lesion was Ketac Fill Plus, followed by Alpha Seal Light and then the Conseal F and Alpha Seal Auto. The material Ketac Fill Plus showed no wall lesion, followed by the other materials in ascending order, Alpha Seal Light, Conseal F and Alpha Seal Auto. Conclusion: The sealant-based glass ionomer cement showed a greater cariostatic effect when compared to others.

Resumo

Objetivo: O objetivo deste estudo foi avaliar o potencial cariostático de quatro diferentes tipos de selantes. Material e método: Foram utilizados 48 incisivos bovinos que foram submetidos à ciclagem de pH. Um sulco com aproximadamente 1 mm de profundidade e 2 mm de largura foi confeccionado para simular um sulco central. As amostras foram divididas aleatoriamente em quatro grupos com 12 amostras cada: Grupo 1) Alpha Seal Auto; Grupo 2) Alpha Seal Ligth; Grupo 3) Conseal F; Grupo 4) Ketac Fill Plus. Em seguida, as amostras foram submetidas à ciclagem térmica e de pH. Foram obtidas três peças de cada dente, que foram analisadas em microscopia de luz polarizada. Foram realizadas as medidas de profundidade da lesão externa e de largura da lesão de parede. Os valores numéricos foram estatisticamente analisados por meio dos testes de Kruskal Wallis e Mann-Whitney, no nível de 5% de significância. Resultado: Observou-se diferença significativa entre os quatro grupos quanto à profundidade das lesões externas (p < 0,05) e à profundidade das lesões de parede (p < 0,01). O material que apresentou a menor profundidade de lesão externa foi o Ketac Fill plus, seguido pelo Alpha Seal Light e então pelo Conseal F e Alpha Seal Auto. O material Ketac Fill plus não apresentou lesão de parede, seguido pelos outros materiais, em ordem crescente: Alpha Seal Light, Conseal F e Alpha Seal Auto. Conclusão: O selante à base de cimento de ionômero de vidro apresentou um maior potencial cariostático quando comparado aos demais.
