    Journal: Am J Dent; 1994 Aug; 7(4):184-6. PubMed ID: 7986431.
    Abstract:
    PURPOSE: To evaluate the effect of three disinfection procedures on the tensile bond strength of Panavia resin composite cement. MATERIALS AND 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.
