Evaluation and comparison of the dimensional stability and tear strength of one commercially available autoclavable addition silicone impression material after being subjected to steam autoclave sterilization
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 3
Abstract
Aims: To evaluate the dimensional stability and tear strength of a commercially available PVS impression material following a stem autoclaving. Settings and design: This study evaluated the effect of autoclaving on elastomeric impressions on dimensional stability and tear strength of PVS impression material (autoclavable) at 3 different time intervals; that is before autoclaving, immediately after autoclaving and 24 hours after autoclaving. Methods and Material: Autoclavable Affinis PVS (light body) Metallic master model (die) for Dimensional stability, Metallic master model (die) for Tear strength, Autoclave, Thermostat regulator, Metallurgical microscope, Universal testing Machine. A total of 55 specimens were fabricated for the study. The metal die for dimensional stability and for tear strength was fabricated. Measurements were made using a measuring microscope. Distance between the cross lines CD and C’D’ reproduced in the impression were measured and labelled at 3 time intervals, dimensional change and tear strength was calculated. Statistical analysis used: A student "t" test was used to ascertain statistical difference between the groups. Result: Results indicate that Affinis PVS (light body) showed no significant change in dimensional stability and tear strength after steam Autoclaving when compared with control group. Conclusion: The present study indicates an effective and easy method of disinfection of impressions that can be achieved by steam autoclaving, without compromising the dimensional stability and tear strength.
