Objective: Previous studies have demonstrated that dental stone casts can be disinfected by replacing 10v% of required water with 5.25% sodium hypochlorite solution. This comparative study evaluated physical properties of dental stone models produced by replacing distilled water with sodium hypochlorite. Methods: In this in-vitro experimental study, a total of 45 dental stone models were pr...
متن کاملPromising role of calcium hypochlorite as a disinfectant: an in vitro evaluation regarding its effect on type V dental stone.
AIM The current study has been chosen to evaluate the efficacy of calcium hypochlorite as a disinfecting additive for the gypsum products and its effect on compressive and tensile strength of the set material. It is hypothesized that, the addition of calcium hypochlorite to type V dental stone in sufficient quantity to disinfect the material would have no deleterious effect on compressive or te...
متن کاملEffect of Disinfection on the Surface Roughness of Dental Casts Retrieved from Addition Silicone Impressions
Background and aim: Changes in the physical properties of casts retrieved from disinfected impressions are a common problem in the fabrication of dental prostheses. However, there are limited data available about the effect of disinfecting solutions on the surface roughness of casts. This study aimed to assess the surface roughness of casts retrieved from addition silicone impressions disinfect...
متن کاملHardness and Surface Detail Reproduction of Gypsum Casts Retrieved from Addition Silicone Impressions Disinfected for Different Time Points
Background and Aim: Bacterial colonization occurs following contamination of impression materials with blood and saliva. However, not all disinfecting agents are compatible with the impression materials and may cause changes in the resultant casts. The purpose of this study was to assess the impact of various immersion time of addi-tion silicon impressions in different disinfecting solutions on...
متن کاملSurface detail reproduction and dimensional accuracy of stone models: influence of disinfectant solutions and alginate impression materials.
This study compared the surface detail reproduction and dimensional accuracy of stone models obtained from molds disinfected with 2% sodium hypochlorite, 2% chlorhexidine digluconate or 0.2% peracetic acid to models produced using molds which were not disinfected, with 3 alginate materials (Cavex ColorChange, Hydrogum 5 and Jeltrate Plus). The molds were prepared over matrix containing 20-, 50-...
