In the 1970s, Schilder used to refer to the then-endodontic attempts at Clean, Shape, Pack “gadgets” as “complicated solutions to nonexistent problems.” He meant that if the endodontic anatomy is eliminated using a compulsive attitude to do so, a capacity for 100% success is available to all dentists. My contracted “Rube Goldberg” cartoon from 1985 reflects this same insight.
