One of the greatest figures in the development of the dental profession to the high status it enjoys today is all but forgotten. Jonathan Taft was dean of the second dental school in the world and wrote the most important clinical textbook of his time, one that was reprinted in many editions over a quarter of a century. Later appointed dean of the new University of Michigan Dental School, he instituted innovations in admission requirements and course of study that were copied by all subsequent schools and are the standards adhered to today. The editor of one of the most important dental journals for 44 years, a record unmatched to this day, he set the standards for modern dental periodical literature that have done so much to elevate dentistry that today it stands on a par with medicine as a truly science-based profession. He served dentistry in many capacities: president of the American Dental Association, founder of the National Association of Dental Faculties, and founder of the National Association of Dental Examiners. Over his lifetime, he published almost 200 professional papers and probably attended and lectured at more dental meetings than anyone of his day and since. His memory should be resurrected, and the profession must be made aware of the great debt it owes to this intrepid fighter for a better dental profession.

Rater reliability: short- and long-term effects of calibration training.

The purpose of this investigation was to evaluate the immediate effects of calibration on inter-rater agreement to a gold standard (GS) and to determine whether the effects can be sustained over a ten-week period. Valid criteria for a Class II amalgam preparation, a three-point rating scale, and a grade form were developed. Three tests were administered: prior to calibration training, immediately following training, and ten weeks later. Each test consisted of faculty independently evaluating ten prepared teeth. Agreement with GS scores for most of the grading criteria improved as a result of training and did not deteriorate over time. The overall percent agreement was 54.5, 66.9, and 64.6 percent across test periods. The most impressive gains in agreement occurred when the criteria evaluated had a GS score of either "standard not met" or "ideal." There was very little gain when the gold standard score was "acceptable." It is concluded that, with training, inter-rater agreement with a gold standard can improve and such improvement is reasonably resistant to deterioration after ten weeks. Nevertheless, future training ought to consider the use of a mastery approach in calibration training to ensure that a satisfactory degree of agreement with the GS is obtained.
