Micro-Raman Vibrational Identification of 10-MDP Bond to Zirconia and Shear Bond Strength Analysis

Figure 3

Micro-Raman spectra of Y-TZP ceramic (Y-TZP), primers-treated ceramics (Y-TZP + CP and Y-TZP + EP), commercial primer (CP), experimental primer (EP), and neat 10-MDP (10-MDP). Peaks at 1636 cm⁻¹ and 1803 cm⁻¹ refer to Zr-O bonds; peak at 1630cm⁻¹ is relative to C=C bonds and 1710 cm⁻¹ to C=O bonds of 10-MDP. Asterisks () are indicating 1545 cm⁻¹ and 1562 cm⁻¹ peaks which only appeared after application of 10-MDP containing primers on Y-TZP ceramics.
