ABSTRACT Objectives: The aim was to evaluate the effect of adding povidone (PVP) iodine powder with different concentrations to irreversible hydrocolloid on both microbiological and dimensional stability. Materials and Methods: Regular set of (alginate) irreversible hydrocolloid was selected as control group. PVP-iodine powder was mixed with the alginate powder at concentrations of 1, 5, 10, 15, and 20% by weight (test groups). All specimens were tested for their antimicrobial effect against Streptococcus mutans and Staphylococcus aureus as well as dimensional stability. Results: The results of test groups showed that concentrations 1, 5, and 10, weight % had little effect against S. mutans and S. aureus microorganisms. While concentrations 15 and 20 weight % had demonstrated greater effect on microbial growth. The mean of dimensional stability in mm of modified alginate with PVP-iodine at 15 and 20 weight % was –0.119 ± 0.255 and –0.035 ± 0.074, respectively. While the mean dimensional stability in mm of unmodified alginate was –0.112 ± 0.176 . The results of dimensional stability showed that 15 and 20 concentrations of test groups adversely affect the dimensional stability. The adverse effect was noticed to be significant in concentration 20%, where as it was nonsignificant in 15% concentration. Conclusion: Modified alginate impression material with 15 weight % PVP-iodine powered give the material, a self-disinfected properties with less deteriorating effect on dimensional stability.
