[Consistency of zinc oxide-eugenol impression materials].
The purpose of this work was investigate the consistency of three zinc oxide-eugenol impression pastes, considering its flow. Flow tests were performed based on the AMERICAN DENTAL ASSOCIATION-Specification no 16. Setting time was based at that one when should be applied the load to get considered disc diameter; the values were obtained graphically. Considering the results it was possible to conclude: a) the first two materials (Equalizing and Horus) present high initial flow, which however drops down earlier on the second one; b) both materials may be used with non compressive impression technic but the second one has shorter working time; c) the third material (Lysanda) as it presents lower flow and faster setting time, may be used with compressive impression technic.
