Evaluation of pre-alginate impression preparation methods in the surface accuracy of dental cast.

Objective: The aim of this study was to investigate the influence of pre-preparation technique (finger smearing and saliva ejection) of alginate impressions on the quality and accuracy of dental casts.

Materials And Methods: Twenty mandibular impressions from 20 patients (10 males, 10 females) with an age range of 20-40 years were recorded using stock trays. A standard impression and pre-preparation technique for alginate were employed.
