The aim of the study was to determine the polyvinylsiloxane impression dimensional stability immersed in 5% chloroxylenol disinfection solution for different durations. The study used Polyvinylsiloxane (Light Bodied), 5% chloroxylenol (Dettol), and a master cast in the form of a block measuring 30mm length, 30mm width, and 20mm height. The research subjects were made by using a mixing gun to mix the catalyst then the impression was taken on the master cast. The research subjects were 16 samples divided into 3 treatment groups of immersion in 5% chloroxylenol disinfectant solution, namely immersion for 5minutes, 10minutes, 20minutes and 0minute for control group, then rinsed with distilled water. Next, the impression was filled with dental stone. The dental stone impression was measured in dimensions (length, width, height) with a manual caliper with an accuracy of 0.05mm and then the volume was calculated. The dimensional changes were measured by reducing the treatment volume with the control volume. The collected data showed that the mean and standard deviation polyvinyl siloxane impressions dimensional changes after immersed in 5% chloroxylenol disinfectant solution were 29.92 12.20 mm3 (5minutes), 59.78 17.25 mm3 (10minutes), 82.17 14.91 mm3 (20minutes). One way ANOVA test result showed p<0.05 and there was a significant difference (p<0.05) among the durations tested. From this study can be concluded that the immersion duration in 5% chloroxylenol disinfectant solution affected on the dimensional stability of the polyvinylsiloxane impression. The longer the immersion duration, the greater the dimensional changes of the polyvinylsiloxane impression. However, all the immersion duration tested were still within the tolerance limits specified by the ADA.
