title: Zirconia-composite bonding after plasma of argon treatment.
abstract: OBJECTIVE
  To compare the shear bond strength (SBS) values of resin cement to zirconia treated with a new activating method.
  
  
  METHODS
  Forty-five zirconia specimens were divided into three groups: no treatment (group 1), plasma of argon cleaning for 375 seconds (group 2), and plasma of argon cleaning for 750 seconds (group 3). Composite cylinders were bonded with a self-adhesive cement. After 40 days of water storage, specimens were subjected to the SBS test. Data were analyzed with one-way analysis of variance and the Neuman-Keuls multiple comparison test.
  
  
  RESULTS
  Test groups obtained SBS values significantly higher (101% for group 2 and 81% for group 3) than controls.
  
  
  CONCLUSIONS
  Plasma of argon appeared to improve bonding between zirconia and resin cement.
