Editor's Note: Sam Weinstein, a great American orthodontist and teacher, once said, "Anybody looking at our radiographic diagnostic measurements would think we are a generation of profiles." He had in mind our preoccupation with the "numbers racket," as he called the myriad numbers of angles, lines, and percentages, based on 2-dimensional lateral cephalometric radiographs. It is hard to believe that it is the 70th anniversary of the first article on radiographic cephalometric assessment by the eminent B. Holly Broadbent. He made it a point to stress the use of both lateral and anteroposterior (frontal) radiographs to determine craniofacial and dental relations, but his pleas were largely ignored. We continue to "count the number of angels on the head of a pin," devising new measurements each year for lateral cephalometric tracings. Amazingly, even with the widespread use of rapid maxillary expansion procedures, preoccupation with the lateral ceph continues. Dr Weinstein did his master's degree research on the use of the frontal radiographic ceph and must be pleased to see belated recognition of his plea to consider the transverse, the third dimension in our diagnosis, before, during, and after treatment in this landmark article. Hopefully, it will stimulate routine 3-dimensional perusal of patients, not only for treatment, but for studying growth and development and long-term stability of treatment results. --T.M. Graber
