摘要: To evaluate and compare the dimensional stability, accuracy surface hardness of three interocclusal recording materials at various time intervals. Polyvinylsiloxane, Zinc oxide eugenol, Aluwax were taken for this study. A stainless steel die ADA specification no 19. was prepared. total ten samples made with each group. The measured using a travelling microscope 10× magnification 1, 24, 48 72 h Five readings sample, mean considered to measure change, hardness. values obtained statistically analysed by ANOVA Tukey HSD-Honestly significant difference. Polyvinylsiloxane most dimensionally stable, accurate had highest among inter-occlusal materials.
