Purpose of study: This study was achieved to evaluate the antimicrobial activity of Lotus essential oil as an additive to condensation silicon impression material during mixing and to evaluate its effect on dimensional stability of impression material.
Materials and Methods:
Microbiological Test: The strains used throughout this study to investigate the effect of augmenting condensation silicon impression material with lotus oil were Pseudomonas aeruginosa ATCC No. 9027, Escherichia coli ATCC No. 8739, Staphylococcus aureus ATCC No. 6538, Streptococcus mutans ATCC No. 700610 and Candida albicans ATCC No. 10231).
Dimensional Change Test: Twenty impressions of Standardized metal die as per ADA specification number #19 were made. Standardized photographs were taken at different time intervals (0, 1, 6, 12 and 24 hours) and the pictures were measured with image processing software.
Microbiological Results: The results demonstrated the effectiveness of lotus oil in reducing the count of examined strains in comparison with the control, a single exception was noted in case of Staphylococcus aureus.
Dimensional stability results: A significant dimensional change immediately after setting, after 6 and 12 hours with addition of Lotus oil to impression material. There was no significant dimensional change after one and 24 hours in comparison with control group.
Conclusion: Addition of Lotus essential oil as a disinfectant to condensation silicon impression material was highly efficient against various pathogens and the dimensional changes were complying the standards of the American Dental Association (ADA) specification 19, which states that acceptable dimensional change should be not more than 0.5%.
