Bonding to dentine with a simplified Gluma system.
In the present study, a number of modifications were introduced in the so-called Gluma resin--a new, simplified bonding system. The amount of acetone in its formulation was altered, or the acetone as well as part of the water were substituted by one of several volatile compounds with the purpose of obtaining a pretreatment of easier clinical application. Some modifications of the pH of the mixtures were also tried. Dentine specimens for shear bond testing were prepared and conditioned with an aluminium oxalate/glycine solution. The dentine surfaces were then treated with the modified Gluma resin mixtures before the placement of the composite resin. Gluma resin formulations containing tetrahydrofuran resulted in acceptable bond strengths, and with formulations of reduced pH, high bond strengths were obtained.
