title: In vitro evaluation of antibacterial efficacy of calcium hydroxide in different vehicles.
abstract: OBJECTIVE
  This study was aimed to evaluate the antibacterial effect of calcium hydroxide (CH) in different vehicles in an in vitro model.
  
  
  METHODS
  Calcium hydroxide paste prepared with two conventionally used vehicles namely, camphorated monochlophenol, distilled water and propylene glycol. The antibacterial activity of these paste were tested against five micro-organisms that can commonly occur in the infected root canals.
  
  
  RESULTS
  The results of this study indicate that a paste of CH made with propylene glycol exerts significant antibacterial action. Hence, it can be recommended for use as an intracanal medicament in preference to a paste prepared with a tissue toxic phenolic compound like camphorated monochlorophenol.
