Efeito da incorporação de hipoclorito de cálcio em gesso tipo III sobre a estabilidade dimensional, resistência à tração diametral e a compressão

Abstract: Neste trabalho foram analisadas as possíveis alterações promovidas pela incorporação de agentes desinfetantes na resistência à compressão, estabilidade dimensional linear e resistência à tração diametral de modelos em gesso. As amostras foram confeccionadas em gesso pedra tipo III e divididas nos seguintes grupos: Grupo 1- controle (espatulado de acordo com as recomendações do fabricante); Grupo 2- adição de 0,5 % de hipoclorito de cálcio; Grupo 3- adição de 1,0 % de hipoclorito de cálcio; Grupo 4- adição de 1… Show more

“…In Lucas et al 16 (2009), where disinfectants were also incorporated during the manipulation of the plaster, a chlorhexidine group showed changes similar to the control group; this finding is similar to the results of the current study, in which a clinically insignificant dimensional change was found in the 4% chlorhexidine group. In the present study, changes were also observed in the group manipulated with 1% sodium hypochlorite when evaluating the distances between the centres of the cylinders, confirming the findings of Ivanovski et al 19 (1995), Scaranelo et al 28 (2004) and Lucas et al 16 (2009).…”

“…Several substances and methods have been studied and are now established disinfection procedures for moulds, casts and related materials. These techniques include dipping the mould in disinfectant solution 8,9,12 , applying disinfectant spray over the mould 13 , immersing the casts 9 , and incorporating the disinfectant substances during the handling of the plaster [14][15][16][17] . In the present study, the latter technique was chosen to eliminate a step in the process of obtaining the casts, with the intention of reducing clinical practice time.…”
