 This study investigated the shear bond strength and fluoride releasing capabilities of clear-fill universal bond quick, clear-fill UBQ, when bonding composite resin to enamel. It found that clear-fill UBQ had comparable shear bond strength to scotch bond, but lower cumulative fluoride release over 30 days. Additionally, it found that clear-fill UBQ released more fluoride in the first two days of the 30-day period than did Fuji 9 or Fuji 2LC.
