Objectives: to observe the effect of alginate impression (hydrocolloid irreversible) immersed on 2% glutaraldehyde
on preventing contamination of Mycobacterium tuberculosis contamination on stone cast.
Methods: This is an experimental research with post test only control group design, with alginate impression
material (hydrocolloid irreversible) is immersed in the 2% glutaraldehyde for 10, 15, and 25 minutes.
Results: This result shows that there is no Mycobacterium tuberculosis contamination on the stone cast after the
immersion of alginate impression material for 10, 15, and 25 minutes. Immersion of alginate impression material
(hydrocolloid reversible) in the glutaraldehyde 2% for 10 minutes is effective to prevent Mycobacterium
tuberculosis contamination on the stone cast.
Conclusions: Immersion of alginate impression on 2% glutaraldehyde for 10 minute was effective to
prevent contamination of Mycobacterium tuberculosis
