Abstract

Background:  The autoclavable impressions which are dimensionally stable are effective in controlling the cross-infection and contamination caused by patient’s saliva and other oral secretions. The aim of present study is to compare the elastic recovery of different elastomeric impression materials on chemical disinfection and autoclaving. Material and methods: The present study compared the elastic recovery of different elastomeric impression materials on chemical disinfection and autoclaving. Materials  used were  AFFINIS, SPEEDEX. The change in length was measured, and percentage deformation was calculated which ultimately provided the elastic recovery. Data was analysed using SPPS 22 version software. P < 0.05 was considered as statistically significant.  Results: In the present study when elastomeric impression material was autoclaved elastic recovery of SPEEDEX was better than AFFINIS. When elastomeric impression material was chemically disinfected elastic recovery of SPEEDEX was better than AFFINIS. When elastomeric impression material was remain untreated elastic recovery of SPEEDEX was better than AFFINIS. Conclusion: Present study concluded that when autoclaved, chemically disinfected and untreated elastic recovery of SPEEDEX was better than AFFINIS.
