| description | Introduction: The present study aimed to determine the effect of different disinfection procedures on the dimensional stability of condensational silicone impression materials.Materials and Methods: In this laboratory study, 84 impressions of an aluminum die were made with condensation silicone impression materials. The impressions were assigned to four groups of 21 based on the disinfection procedures: immersion in the 5.25% sodium hypochlorite, immersion in 2% glutaraldehyde solution, and the use of spray deconex. The impressions which were not disinfected served as controls. After treatments, impressions were poured, and respective stone casts were measured and compared with the aluminum die at three dimensions of mesiodistal, occlusogingival, and buccolingual, as well as the space between two dies. The obtained results were reported by ANOVA.Results: Based on the results, 5.25% Sodium hypochlorite and deconex showed the most significant dimensional changes in terms of increasing die height. Moreover, in terms of the distance between the two dies, sodium hypochlorite demonstrated the least dimensional changes and did not differ from the control group. Sodium hypochlorite solution led to a significant increase in buccolingual and mesiodistal dimensions of die. Nonetheless, the glutaraldehyde solution reduced these dimensions. The dimensional changes of the deconex group and the control groups were not significantly different.Conclusion: The impressions of the control group showed the least dimensional changes of buccolingual, mesiodistal, and height, and also there was no significant difference between control and sodium hypochlorite groups in terms of the distance between the two dies. The use of glutaraldehyde in clinical practice is recommended for the disinfection of impressions that have been fabricated for the fixed single crowns. |
