Influence of Disinfecting Solutions on the Surface Roughness of Zinc-Oxide Eugenol Impression Material

Dental impression can act as arole of transmission of infection. Difficulties in sterilizing impression by conventional methods have led to chemical disinfection as substitution.

Evaluate the effect of natural disinfection solutions(Apple Vinegar and Lemon Juice) on surface roughness of Zinc-oxideeugenol impression material.

fiftysampleswere prepared from zinc-oxide eugenolimpression materials and divided into control groupwhich exposed to saliva for five minutes and experimental groups which exposed to saliva then disinfectant agents (lemon juice and apple vinegar solution).surface roughness of samples were analyzed for control group and experimental groups after 10 and 15 minute.

data recorded from surface roughness test accounted lower mean values in control group and high mean values in lemon juice group followed by apple vinegar group. ANOVA test and LSD revealed that highly significant differences at p < 0.001between tested groups.

The study revealed that the immersion of ZOE in lemon juice solution and apple vinegar solution adversely affect surface roughness at 10 and 15 minutes
