The aim of this study was to evaluate the effect of die lubricant on the fit of wax patterns. An ivorine tooth was prepared to receive full-coverage metal-ceramic restoration with 360° shoulder finish line. The tooth was duplicated 40 times using additional silicone. The impression was poured with Type IV dental stone. These 40 dies were divided into 2 groups 20 each. Group A: The patterns were fabricated with the use of die lubricant. Group B: The patterns were fabricated without the use of die lubricant. Later, these patterns were sequentially checked for the marginal fit on the stereomicroscope. The readings from the stereomicroscope were tabulated; independent Student's t-test was used to compare the marginal fit between Group A and Group B. The mean gap on all four tooth surfaces in Group A (with use of die lubricant) was more compared to Group B (without use of die lubricant). Conclusion: Die lubricant definitely has their effect on fit of the wax pattern which later might be duplicated in the casting.
