BACKGROUND: Studies regarding the effect of various methods to increase the surface @entity3358 of @entity3466 are not conclusive. Therefore, this study was carried out to evaluate the effect of air drying, micro oven drying and die hardener on surface @entity3358 of @entity3466 . MATERIALS AND METHODS: A standard metal die was fabricated; @entity11945 impression material was used to make the molds of metal die. A total of 120 specimens were obtained from two different die stones and were grouped as Group A (kalrock) and Group B (pearl stone), and were subjected to air drying for 24 h, micro oven drying and application of die hardener. These models were then subjected to surface @entity3358 testing using the knoop @entity3358 instrument. The obtained data were subjected to statistical analysis. RESULTS: The @entity3358 of Group A specimens was 64    0.54 @entity3358 ( @entity3358 ) after application of die hardener, 60.47    0.41 @entity3358 after 24 h air drying, 58.2    0.88 after microwave oven drying and 24.6    0.4 after 1 h air drying. The @entity3358 of Group B specimens was 45.59    0.63 @entity3358 after application of die hardener, 40.2    0.63 @entity3358 after 24 h air drying, 38.28    0.55 @entity3358 after microwave oven drying and 19.91    0.64 @entity3358 after 1 h air drying. CONCLUSION: Group A showed better results than Group B at all times. Application of the die hardener showed highest @entity3358 values followed in the order by 24 h air drying, microwave oven drying and 1 h air drying in both groups. The study showed that air drying the dies for 24 h followed by application of a single layer of the die hardener produced the best surface @entity3358 and is recommended to be followed in practice.
