Cleaning denture have the most important point to dentist
because it has the most effect in the live of the removable
denture and in the health of the mouth tissue , so we must to
share between mechanical cleaning with tooth brush and with
chemic
al cleaning to kill the bacteria and candida albican and to
remove food depris from the denture surface . there are many
disinfection solutions for removable denture so we have to do a
research for effect of these solutions on the removable denture
which made from Crom Cobalt alloy, and on the candida albican
colonization on the denture surface .
The current research aims to study the effect of chemical disinfectants
on the roughness and hardness of the surface of the cobalt chrome
alloy, where the use of cleansing Sodium hypochlorite 5.25%
and distilled water (the control sample), Been ma
nufacturing 20
structure metal of the alloy cobalt chrome, each group containing 10
samples and was doused with samples intravenously cleared, then it
was measured surface roughness using an Atomic force microscope, and
measuring the hardness of the surface using a Vickers measuring device
hardness.
