AB  - OBJECTIVE: The purpose of this study was to investigate the effects of carbon 
      dioxide (CO2) and Erbium-doped yttrium aluminum garnet (Er:YAG) laser 
      irradiations on the shear bond strength (SBS) of differently sintered zirconia 
      ceramics to resin cement. MATERIALS AND METHODS: Eighty zirconia specimens were 
      prepared, sintered in two different periods (short = Ss, long = Ls), and divided 
      into four treatment groups (n = 10 each). These groups were (a) untreated 
      (control), (b) Er:YAG laser irradiated with 6 W power for 5 sec, (c) CO2 laser 
      with 2 W power for 10 sec, (d) CO2 laser with 4 W power for 10 sec. Scanning 
      electron microscope (SEM) images were recorded for each of the eight groups. 
      Eighty composite resin discs (3 x 3 mm) were fabricated and cemented with an 
      adhesive resin cement to ceramic specimens. The SBS test was performed after 
      specimens were stored in water for 24 h by an universal testing machine at a 
      crosshead speed of 1 mm/min. Data were statistically analyzed with two way 
      analysis of variance (ANOVA) and Tukey honest significant difference (HSD) test 
      (alpha = 0.05). RESULTS: According to the ANOVA, the sintering time, surface 
      treatments and their interaction were statistically significant (p < 0.05). 
      Although each of the laser-irradiated groups were significantly higher than the 
      control groups, there was no statistically significant difference among them 
      (p > 0.05). CONCLUSIONS: Variation in sintering time from 2.5 to 5.0 h may have 
      influenced the SBS of Yttrium-stabilized tetragonal zirconia polycrystalline 
      (Y-TZP) ceramics. Although CO2 and Er:YAG laser irradiation techniques may 
      increase the SBS values of both tested zirconia ceramics, they are recommended 
      for clinicians as an alternative pretreatment method.
