Synthesis of the dental adhesive materials were done by Ultradent formulation scientists using 30g batches per sample. Formulations were weighed, and mixing was done using a FlackTek speedmixer to ensure uniformity. Seven samples from a 30g batch were taken for testing each new formulation. The mean value of the 7 samples used to measure shear bond to dentin was taken as the value of the materials shear bond. The standard followed to test these new formulations was done per the International Organization for Standardization 29022 (ISO 29022).
