Abstract

The objective of this study was to evaluate the influence of the cavity preparation technique and fluoride-containing restorative materials on the prevention of the secondary caries. Human teeth were sectioned into 72 blocks and distributed into 2 groups. Cavities measuring 1.6mm were performed with diamond burs or Er:YAG laser (6Hz, 300mJ, 47 J/cm2). Each group was divided into 3 sub-groups, and restored with a glass-ionomer cement, resin-modified glass-ionomer, or composite resin. The specimens were thermal cycled and submitted to pH cycling. Artificial caries were scored using an ordinal scale based on visual inspection. Kruskal-Wallis and Dunn test (α=0.05) showed no differences in the caries lesion development between the cavities restored with the same material and prepared with diamond burs or Er:YAG laser. The Er:YAG laser used for cavity preparation used with 6Hz, 300mJ, 47 J/cm2 did not show the ability to guarantee significantly more acid-resistance against acid challenge.

Resumo

O objetivo desse estudo foi avaliar a influencia da técnica de preparo cavitário e de materiais restauradores contendo flúor na prevenção da secundária. Dentes humanos foram seccionados em 72 blocos e distribuídos em dois grupos. Cavidades com 1.6mm  de diâmetro foram preparadas com pontas diamantadas ou laser de Er:YAG laser (6Hz, 300mJ, 47 J/cm2). Cada grupo foi dividido em três subgrupos e restaurados com cimento de ionômero de vidro, ionômero de vidro modificado por poliácido ou uma resina composta. Os espécimes foram termociclados e submetidos a ciclagem de pH. As lesões de cárie artificial foram ranqueadas utilizando uma escala ordinal por inspeção visual. Os testes de Kruskal-Wallis e Dunn (α=0.05) não demonstraram diferenças no desenvolvimento de lesões entre as cavidades resturadas com o mesmo material e preparadas com pontas diamantadas ou laser de Er:YAG laser. O laser de Er:YAG utilizado para o preparo cavitário com 6Hz, 300mJ, 47 J/cm2 não demonstrou  a habilidade de garantir maior ácido resistência aos preparos.
