The dentine surface was further abraded with 240-grit silicon carbide paper, until a remaining dentine thickness (RDT) of 1.0 ± 0.2 mm was achieved from the ground surface to the highest pulp horn. The RDT was measured by placing one fine tine of a ÔCÕshaped digital micrometer in the deepest pulp horn and another on the flat dentine surface opposite that pulp horn.
