Effect of Surfosept and Deconex® 53 Disinfectant Agents On The Accuracy And Dimensional Stability Of Panasil Dental Impression Materials: An In-Vitro Experimental Study

Aim and Objective: Impression materials and BegoStone casts are the main sources of cross-contamination and transmission of dental infections between dental professionals.Considering the influence of disinfection substanceson the dimensions of impression materials, this study was aimed to compare the effect of Surfosept and Deconex® 53 on the accuracy and dimensional stability of dental addition siliconematerial i.e., Panasil®. Material and Method: This in-vitro study was performed on 30 casts. The samples were divided into one control group and two experimental groups to be disinfected with Surfosept(1%) and Deconex®53 (2%)using a sequential sampling method (10 per group).The impressions in the experimental groups (i.e., Surfosept and Deconex®53)were rinsedand dried,thenthe disinfectant was sprayed on the impressions and remained for 30seconds before pouring with stone. In the control group, the impressions were onlyrinsedand dried, andwere pouredin 10 minutes. Cast dimensions were measured by a profile projector device, and the mean values obtained from the experimental groups were compared with those of the control group. Results: There were no significant differences among the groups regarding the height of the resulting dies without undercut (P=0.62). Moreover, there was no significant difference among the groups regarding the distance between the two dies (P=0.77). However, in terms of the diameter of the dies without undercut, a significant difference was observed among the groups(P<0.005). Conclusion: In general, no significant difference was encountered between dimensional stability and accuracy of the dental impressions using Surfosept and Deconex®53 in this study
