Abstract

Objective: To compare changes, in linear dimension of Alginate impression by disinfection with immersion in 0.525% Sodium Hypochlorite solution and no disinfection. Study Design: Randomized Control Trial. Setting: Department of Prosthodontics, Punjab Dental Hospital Lahore. Period: April 2018 to September 2018. Material & Methods: Sixty alginate impressions were made of a stainless steel die and were randomly divided into two groups. The 30 control group impressions were poured only after rinsing with tap water, whereas the 30 experimental group impressions were first immersed in 0.525% Sodium Hypochlorite solution for 10 minutes and then poured after rinsing with tap water. The distance between two engraved lines C and D on die were measured in the casts of both groups. Results: The mean difference of mean dimensional changes between both methods was 0.01mm. Conclusion: The disinfection of the alginate impression material by immersion in 0.525% Sodium Hypochlorite solution does not cause significant effect on dimensional stability of alginate impression material.
