title: Evaluation of Different Disinfactants on Dimensional Accuracy and Surface Quality of Type IV Gypsum Casts Retrieved from Elastomeric Impression Materials.
abstract: BACKGROUND
  The present study was done to evaluate the dimensional stability and surface quality of Type IV gypsum casts retrieved from disinfected elastomeric impression materials.
  
  
  METHODS
  In an in vitro study contaminated impression material with known bacterial species was disinfected with disinfectants followed by culturing the swab sample to assess reduction in level of bacterial colony. Changes in surface detail reproduction of impression were assessed fallowing disinfection.
  
  
  RESULTS
  All the three disinfectants used in the study produced a 100% reduction in colony forming units of the test organisms.
  
  
  CONCLUSIONS
  All the three disinfectants produced complete disinfection, and didn't cause any deterioration in surface detail reproduction.
