title: Disinfectant storage media and composite/metal bond strength.
abstract: OBJECTIVE
  To evaluate the effect of three disinfection procedures on the tensile bond strength of Panavia resin composite cement.
  
  
  METHODS
  Alloy cylinders were bonded and stored in: (1) 0.2% chlorhexidine; (2) 2% activated glutaraldehyde; (3) distilled water and sterilized with ethylene oxide; and (4) distilled water. Solutions were monitored for bacterial cultures and pH changes regularly for 90 days after which all samples were tested to tensile failure.
  
  
  RESULTS
  ANOVA showed no significant difference between mean group bond strengths. A direct positive correlation was demonstrated between solution pH and bond strengths (r = 0.98). All groups were found to represent effective methods for preventing bacterial growth in storage solutions during long term cement bonding studies.
