ROLE OF THREE DIFFERENT DISINFECTANTS FOR PREVENTING BACTERIAL GROWTH IN DENTAL IMPRESSION MATERIAL

Background:
 Dental impressions become contaminated with micro-organism from patient’s saliva and blood which can cross-infect stone cast poured against them. The aim of the present study was to compare efficacy commercially available disinfection products, one containing glutaraldehyde, sodium hypo chloride ethanol for material.
 Methods: For this investigations, dental impression 60 patients were taken. Impression made in 5 mm slices each disinfectants. Sectioned immersed gluteral aldehyde, chloride, solutions. Antibacterial property these disinfectants evaluated by inoculating sample saline solution into nutrient agar medium.
 Results: There is no significant different between three disinfecting (P<0.05).all seems effective bacterial growth.
 Conclusions: Addition silicone should always be disinfected after water wash order reduce effectively cross-infection risk. All tested showed high antimicrobial efficiency. Ethanol good economical alternative addition silicone.
